Back to Basics: Blue vs. Green Hydrogen

Anyone who follows current events knows that we are currently in a race against time when it comes to offsetting the effects of global warming. Transport emissions are a key part of this race as, in today’s globalised society, they contribute significantly to the rises in temperatures throughout the globe. According to the International Energy Agency tracking report from 2022, transport emissions are responsible for roughly 7.7 Gt CO2 annually – a number that needs to drop to less than 6 Gt before the end of the current decade if we want to reach the Net Zero goal set by the UN.

From biofuels, to liquified natural gas, to electric batteries – the transport sector is currently exploring a variety of solutions that can be put in place to make transport cleaner whilst maintaining its efficiency. One such alternative fuel source is hydrogen – a lot of hype has been given to this fuel source in the industry – and this is why we chose it as the focus of our #BacktoBasics article this month.

What is hydrogen?

Most of us know the formula for the element – H2. We know it is colourless, has no taste or smell, and is highly combustible –we learned this in school. In recent years, research has helped us develop systems that can transform the heat generated by this element into energy.

Today, in many sectors of our society, hydrogen is already being used as a “clean” source of energy. Some such examples are:

  1. Fuel cell electric vehicles (FCEVs): FCEVs use hydrogen fuel cells to generate electricity, which then powers the vehicle’s electric motor. FCEVs have a longer range than battery electric vehicles and can be refuelled in a matter of minutes.
  2. Hydrogen internal combustion engines (HICEs): HICEs are like traditional gasoline or diesel engines but use hydrogen as the fuel source. HICEs produce lower emissions than traditional engines, but not as low as fuel cell electric vehicles.
  3. Hydrogen-powered buses: Several cities around the world have implemented hydrogen-powered buses in their public transit systems (including London (England), Aberdeen (Scotland), Cologne (Germany) and Tokyo (Japan). These buses emit only water vapor and have similar range and refuelling times as FCEVs.
  4. Hydrogen-powered trains: Hydrogen fuel cells are being used to power trains in some areas, such as Germany and the UK. These trains emit only water vapor and have lower noise levels compared to diesel trains.

When thinking about the freight transport sector, we can see that we already have:

  1. Hydrogen fuel cell trucks: Several companies are developing fuel cell-powered trucks for cargo transport (including Toyota and Kenworth). These trucks have a range of several hundred miles and emit only water vapor.
  2. Hydrogen-powered forklifts: Hydrogen fuel cells are being used to power forklifts in warehouses and distribution centres. These forklifts have the advantage of emitting only water vapour and refuelling quickly, reducing downtime compared to battery-powered forklifts.
  3. Hydrogen-powered trains: hydrogen fuel cells are being used to power trains in some areas. These trains could potentially be used for cargo transport as well, with the added benefit of emitting only water vapour and having lower noise levels compared to diesel trains.
  4. Maritime transport: There are several projects underway to develop hydrogen-powered ships for cargo transport. For example, the Hydrogen Energy Supply Chain project in Japan is developing a hydrogen-powered supply chain for liquefied natural gas transport.
  5. Air cargo transport: While hydrogen is not yet being used for commercial air transport, there are several projects underway to develop hydrogen-powered aircraft. For example, Airbus is developing a concept for a zero-emissions aircraft powered by hydrogen fuel cells.

Green or Blue (or both?)

Hydrogen is a clean-burning fuel that can be produced from a variety of sources, including natural gas, biomass, and renewable energy. Blue and green hydrogen are two different types of hydrogen production methods that have distinct differences in terms of their environmental impact and production processes;

  1. Green hydrogen

It is produced through the process of electrolysis, which uses electricity to split water molecules into hydrogen and oxygen. The electricity can be generated from renewable sources such as wind, solar, and hydroelectric power. Since green hydrogen is produced using renewable energy, it is generally considered a clean fuel that has a low carbon footprint. It can be used in fuel cell vehicles, which are powered by hydrogen and emit only water vapor as a by-product. The use of green hydrogen in transport can significantly reduce greenhouse gas emissions and contribute to a more sustainable future.

  1. Blue hydrogen

It is produced from natural gas using a process called steam methane reforming (SMR). During SMR, natural gas is heated with steam to produce hydrogen and carbon monoxide. The carbon monoxide is then converted into carbon dioxide, which is captured and stored underground. This process is known as carbon captureutilisation, and storage (CCUS), which helps reduce greenhouse gas emissions by storing carbon dioxide instead of releasing it into the atmosphere. While blue hydrogen is considered to have a lower carbon footprint than conventional natural gas, it still relies on fossil fuels, making it less environmentally friendly than green hydrogen.

Both green and blue hydrogen can (and are) be used in fuel cell vehicles. However, since green hydrogen is produced using renewable energy, it is considered the most sustainable and environmentally friendly option for transport today. Blue hydrogen, on the other hand, is considered a transitional fuel that can help reduce greenhouse gas emissions while the world transitions to a fully renewable energy system.

According to a report by the International Energy Agency (IEA), the use of blue hydrogen in transport can reduce greenhouse gas emissions by up to 30% compared to conventional gasoline or diesel vehicles. However, the report also notes that blue hydrogen should be used as a stepping stone to green hydrogen, which is the ultimate goal for a sustainable hydrogen economy.

Final thoughts

At the moment it is still unclear which hydrogen option the markets will favour. Blue and green hydrogen are essentially depictions of two different types of hydrogen production methods that have differences in terms of their environmental impact and production processes. Most experts agree that “green” is the better option as it appears to be a net-zero fuel. It is unfortunately also true that green hydrogen is the most expensive one to make (Forbes estimated the production of green hydrogen at $6/kilogram – 2-3 times more expensive than blue hydrogen). Thus, it can be said that most industry members would opt for the blue option – at least in the short term. While blue hydrogen can help reduce greenhouse gas emissions, green hydrogen remains the more sustainable and environmentally friendly option for transport. So, while we work on making green hydrogen more accessible to the markets, we can remain satisfied with the knowledge that even with blue H we are keeping pace with the global warming race. After all, the use of hydrogen (any hydrogen) as a fuel in transport can significantly reduce greenhouse gas emissions and contribute to a more sustainable future.

Container terminal at the Port of Long Beach

Zero Emissions future – the case of the Port of Long Beach

Written by Lidia Slawinska

Written by: Lidia Slawinska, Digital Communications

A net-zero operating terminal is a milestone that most ports around the globe are working towards – as it would mark a significant step towards sustainability. This summer, one port has achieved this remarkable step and begun operating a container terminal that is equipped with nearly all electric and zero-emissions equipment. Already news sources are reporting it as one of the most technologically advanced cargo terminals globally. We are, of course, talking about the Port of Long Beach – and the Long Beach Container Terminal at Middle Harbor (in California, USA) – and we wanted to take a look at it in this #DidYouKnow article.

A decade in the making

The port begun work on the project in May 2011, with an initial estimated cost of $1.5bln. The project was divided in three distinct phases. The first phase was completed in 2016, after which 151 acres opened for business. The next year the terminal was expanded to reach 191 acres, and the final phase of the project ended in July 2021. The Container Terminal now boasts with 300 acres in size, has a completed container yard, a modern administration buiding and an on-dock rail yard to allow for intermodal traffic. The concrete wharf can also receive and process three massive ships at once, with fourteen gantry cranes able to service the shoreline.

The terminal is expected to expand through the North Gate Expansion by 2025, adding an additional 3 acres to the already impressive surface area of the facility.

Net zero emissions

It is doubtlessly difficult for ports to make sure that their operations are carbon neutral – and in line with the global environmental agencies recommendations for the protection of our climate. How did the Port of Long Beach achieve its net zero emissions?

First of all – it ensured sufficient on-shore power supply stations on the berths. All of the vessels are now able to shut down the diesel engines while stationed in port and can connect to the local electrical grid.

Secondly, during the construction it was ensured that all of the major structures were built with features that allow them to save both electricity and water, meeting the American Leadership in Energy and Environmental Design standards.

In-terminal operations are carried out by automated guided vehicles that rely on transponders in the asphalt to manoeuvre around the containers. These vehicles are battery-operated and are also capable of recharging themselves.

The final aspect of the Californian terminal is the emphasis that has been placed on faster truck turnaround times, which further reduced the port’s emissions.

Intermodality at the forefront

There is no doubt that one of the aspects that port terminals can focus on is to increase their intermodal capacities – as bringing trucks off the roads would significantly lower the GHG emissions produced by their diesel engines. The Port of Long Beach was not an exception, and in its construction has included a intermodal rail yard that includes 70,000ft of tracks. “There are 12 tracks, and each is almost a mile long,” says Thomas Baldwin, director of project management at the port. “There are four storage tracks, and eight working tracks. Five dual cantilevered gantry cranes with room for a sixth. It’s one of most modern railyards ever built, with 1.1 million-TEU capacity ” (August 20th, 2021: ENR). In the near future, the port is also planning to expand its on-dock rail capacity to 35%, acknowledging that one fully stacked train can replace up to seventy-five trucks on the road – further alleviating the pressure on our environment.

Innovating into a clean energy future

Becoming a green port is no small feat. There are many innovative ports in the world that have already incorporated significant changes to their operations to lower their emissions and thus conform with international standards. The Long Beach Container Terminal can certainly be used as an example for other ports to follow, as it shows the signs of being the world’s first “all-electric, zero-emission mega terminal” and “will [help the port] increase [its] throughput, improve air quality and maintain [its] status as a leading gateway for trans-Pacific trade” – as was highlighted by Maria Cordero, the executive director of the port (August 23rd, 2021: Splash 247).

Sustainability

Sustainability of transport and logistics in the Mediterranean

Written by Eduard Rodés, Director of the Escola Europea

Written by Eduard Rodés, Director of the Escola Europea

The concept of sustainability, although open to many interpretations, can be understood as based on two elements. The first is the transport network, which is, at European level, fundamentally structured by the work carried out in recent years by the European Commission (EC) on the Trans-European Transportation Network (TEN-T) and which necessarily conditions that of its neighbouring countries, and therefore by extension Mediterranean countries. The transport network is one of the three networks that are essential for economic and social development. The second element is made of the energy and telecommunications networks, which are elements of the digitalisation process. The transport network is dependent on the other two, both in terms of efficiency and sustainability.

The efforts to advance the concept of sustainability are based on the approval by the United Nations (UN) Assembly of the 2030 Agenda in September 2015, structured by the 17 Sustainable Development Goals (SDG). Sustainable development cannot be understood without simultaneously taking into account the interrelationship between the different goals. Spending more time trying to scrutinise the aspects related to Goal 13 on climate change, or Goal 9, which deals with industry, innovation and infrastructure in this article would not be wise, as they depend to a broad extent on the other 15 goals and their mutual interactions to reach the targets. It is most likely that the problem to solve is not pollution or sustainability but the consequences we are facing from our actions in the past two centuries. The underlying problem is our way of life and the habits we have acquired. This is where the COVID-19 pandemic has forced our societies to look at themselves in the mirror. It can now be understood that another way of organising our societies is possible and that everything is more ephemeral and fragile than previously thought.

Sustainability has become one of the critical factors in shaping the policies of all countries. The United Nations, with its Agenda 2030 initiative, and the European Union (EU) with the Green Deal, has set the course for a low-carbon society in 2050. The COVID-19 has further strengthened the need to carry out this sustainability revolution. The road ahead will not be easy and will inevitably lead to drastic changes in the configuration of the transport and logistics sector.

A World in Transition

COVID-19 appeared in the middle of a period of strong transition. Time will tell if there is a change of cycle, leaving behind the silicon and information period, and moved towards robotics, artificial intelligence, and simulation models in virtual environments. Now, the systems we are developing are prepared to aggregate much more data than we have ever had. The programmes can analyse it and simulate scenarios on which to base decisions, much more accurately than those we would have been able to make without their help. This transition is taking place in the three networks previously identified (transport, energy and telecommunications) and as a result of their evolution.

The Energy Transition

The Mediterranean, like the rest of the world, faces the need to seek out renewable energy sources. The consumption of hydrocarbons and energy produced with fossil fuels is reaching the end of the cycle. Governments face the need to seek alternatives that will maintain economic activity while reducing the environmental impact of emissions. Energy efficiency and the progressive penetration of renewable energies must enable economic reactivation in the short term and, at the same time, allow for the consolidation of the value chain associated with their deployment. They are also the pillars of decarbonisation, which gives a boost to the rest of the sectors while improving business and industrial competitiveness through a downward price path.

The energy transition also promotes the implementation and development of new technologies, which are fundamental for managing the demand for electricity and the supply of security in a 100% renewable system, in an industry segment in which the Mediterranean has the potential to acquire leading positions.

The development of hybrid plants allows for more flexibility. Different types of technologies can coexist in the same system, which can already be seen, for example, in wind power plants utilising solar panels. In such cases, the energy can be distributed using the same connection point and the access capacity already granted, provided that the technical requirements are met.

According to the Observatoire Méditerranéen de l’Energie (OME), “it is estimated that energy demand per capita will increase by 62% in the Southern and Eastern Mediterranean countries by 2040 (using 2018 as the reference year). The Mediterranean region is also experiencing intense industrialisation and growth in tourism, putting additional pressure on available energy resources” (UfM, 2019).

These regional challenges, if adequately addressed, can be turned into business opportunities that can contribute to a sustainable energy transition. The Mediterranean is rich in renewable energy sources, such as wind, sun and water. Therefore, it has the potential to promote the transition to more sustainable and low-carbon energy systems. There is also the potential to increase energy efficiency through the development of new technologies that allow, for example, energy-saving and storage. Moreover, the development of gas and energy transmission interconnections will lead to the progressive integration of energy markets in the region, which is an opportunity for countries to better address the energy security challenges.

The problem is addressed from various perspectives depending on the “community” from which it is analysed. The most visible today is the city, which is currently undergoing a process of significant changes due to the evolution of distribution caused by the rapid growth of e-commerce (further accelerated by the COVID-19).

Ports have initiated determined shifts towards an energy transition in their territories. This has led to the emergence of professions such as officers in charge of the energy transition. The working programmes go through the different elements that make up energy consumption and their sources of production.

The first issue is a legislative framework that has been developed to force the transition while maintaining a certain rate of deployment. A second point relates to savings and efficiency policies, as these are aspects that can be applied immediately and with excellent results if used correctly. A third issue relates to energy sources, and significant changes have already been made in recent years in this regard. Gas has played a leading role in the last ten years, and during this period gas-powered ships have been built, supply systems for trucks have been developed, and some tests with port machinery have been established.

One of the critical aspects that condition the implementation process of low-sulphur fuels with low CO2 emissions is the possibility of the Mediterranean being declared an Emission Control Area (ECA). This is one of the most rapidly changing scenarios for the future. The Mediterranean will be an ECA area no later than 2024, as decided at the meeting of the Contracting Parties to the Barcelona Convention (COP21) held in December 2019 in Naples. The agreement will lead to the presentation of the proposal at the Marine Environment Protection Committee (MEPC) of the International Maritime Organisation (IMO) in 2022.

This is a significant challenge for the shipping companies, which have been working on the emission reduction aspects for years. In 2018, the IMO adopted Resolution 304(72) on the initial strategy for the reduction of greenhouse gas (GHG) emissions from ships, which set a reduction of 40% by 2030 and 70% by 2050. The lifespan of a vessel is approximately 30 years, so times should be calculated taking this into account (IMO, 2018).

Today’s large fuel families are also in transition. Liquefied natural gas is evolving towards biomethane and hydrogen, biodiesel to second and third-generation biofuels, liquid petroleum gas to biogases, and bioethanol to synthetic ones. In all cases, it will be necessary for ships to dedicate more space to storage, as the energy power is lower, and they will need a higher quantity for a result similar to what is attained using traditional fuels.

Maritime transport in the Mediterranean is considered to be “Short Sea Shipping”, which in turn represents 80% of the world’s fleet and one of the main contributors to air quality in port cities. Ports in the Mediterranean are generally located in big cities and operate alongside them, seeking a balance between the advantages of having a port that provides a service and the disadvantages of port-related operations. What is clear is that Short Sea Shipping is configured as a network in the area in which it operates. Ships from the Southern Mediterranean work with the countries of the North and vice versa. Therefore, the regulations that will be implemented will necessarily affect practically all operations. It seems clear that governments will use coercive measures to force a rapid move towards carbon-neutral solutions.

At present in Spain, gas is at the forefront with a prepared infrastructure that will make it possible to reach 2035 without the need to invest in this concept. For operators, it is profitable because they must bear a significant initial investment to adapt their ships. Still, the cost of fuel is more economical, allowing a return on investment in a relatively short time.

In recent months, hydrogen has been gaining ground as an alternative to traditional fuels in maritime transport for several reasons. It is abundant and available everywhere. In a fuel cell, the generated waste is O2 and water. As a fuel, it has zero emissions, is not toxic, is not a greenhouse gas, can be produced from renewable resources, and is a source for other fuels such as e-fuels and blue fuels. We will have to get used to new nomenclatures such as “Green Hydrogen” produced from renewable energies or “Blue Hydrogen” generated from gas, which generates CO2 in the production process that is captured and stored in underground deposits. Hydrogen has the disadvantage of being difficult to store and transport, and involves complementary elements such as ammonium, ethanol and octane. Ammonia stands out as it is a substance that does not contain carbon in its molecule and therefore does not generate CO2 emissions during its decomposition reaction, besides being the second most-produced chemical compound worldwide after sulphuric acid.

Research is currently underway for the subsequent decomposition of ammonia for its use with catalysts. These include graphene, which due to its characteristics could be an ideal candidate. From a Mediterranean point of view, it is clear that energy sources based mainly on solar energy and gas provide a significant competitive advantage, as the changes that are expected to occur are relatively rapid.

The Digital Transition

To understand what is happening in telecommunications systems, it is worth analysing the role that they have played during the pandemic. It is no longer a question of seeing how technology evolves in the field of communications and how it will affect us. It is about realising that society has been re-structured around a different way of making and maintaining relationships, driven at this time by the pandemic, which, we all assume, will remain as a new form of interaction. The pandemic has accelerated the digital transition, thus reconfiguring human and environmental relationships. At the expense of proximity, some interactions have been enhanced and our environmental impact reduced. During this period, a reasonably high level of educational activity has been successfully maintained. International projects have been supported, many people have teleworked, and the reality is that it seems that quite a few will continue to do so, even if only partially, for the foreseeable future (if not forever). Interestingly, none of this would have been possible without a significant development in digitalisation.

Two clear consequences of this pandemic have been the drastic reduction in mobility and the exponential increase in e-commerce and door-to-door sales. All of it was possible, based on a working system supported by telematics and the digitalisation of documentation and associated information. Everything that was being developed in the world of transport has accelerated rapidly, and where before everyone was putting obstacles in the way, now everyone is looking for solutions. If something could be done telematically, it was done, whether it was administrative boards or family meetings. Some changes will be more disruptive, such as the 5G technology that will allow exchanges of information in real time. This is understandable as there will be no latencies in communications. This is linked to the important development of robotic processes.

Another essential aspect linked to the energy network is its management and use. The “Smart Grid” concept is based on a form of efficient electricity management that uses computer technology to optimise the production and distribution of electricity, to better balance supply and demand between producers and consumers, and to improve the security and quality of supply following the requirements of the digital age. Better energy management will make it possible to create energy communities that will self-manage their production and consumption. Initiatives in this direction are being considered in the Port of Barcelona itself, but the idea goes further. This capacity for knowledge and management that a computerised world allows gives rise to different systems of governance, dependence and resilience. Fortunately, it is not a question of technologies that are difficult to access for the countries of the Mediterranean basin, which already have the necessary energy and know-how.

Digitalisation has a fundamental impact on transport. Advances in digital mapping systems, fleet and transportation management and the development of mobility management networks are transforming its landscape. Each transport system has its network. For land transport, the European Commission is working with the “Intelligent Transport System”, which enables an integrated system of information for traffic, safety, efficiency and sustainability. In short, it is working on the efficient management of the transport network based on the mass collection of data and interaction with the vehicles and drivers themselves.

In the maritime world, the Safe Sea Net, the vessel traffic monitoring in EU waters, managed by the “European Maritime Safety Agency”, is gaining importance. Through it, it is possible to monitor the movement of ships in the Mediterranean, which in turn makes it possible to control environmental aspects with the Clean Sea Net service. The European Commission has continued to improve single window systems with a new initiative born at the height of the pandemic, namely the “EU Single Window Environment for Customs”, which aims to facilitate the actions of the various public administrations involved in the clearance of goods entering and leaving the Union.

The ports have entered a period of digitalisation of all their operations and territories. The Internet of things (IoT) has made it easier to have a massive amount of information available, which in turn has made it possible to create a knowledge base on which to support much more efficient management systems. Ships have become sophisticated centres of sensors and data generators, producing and transmitting information from anywhere, often in real time. At the same time, advances in satellite communications are improving connectivity, allowing for massive increases in the volumes of data transferred at an ever-lower cost.

The Transition of the Transport Network

Finally, the transition of the transport network, supported by infrastructure and physical characteristics, and which include ships, trains and trucks, and structured around energy and information, needs to be addressed. When talking about transport in the Mediterranean, we need to discuss what the European Commission defines as the Motorways of the Sea and Short Sea Shipping. The Commission is considering the creation of a single European maritime space and, in a way, a Mediterranean space. For the Commission’s Motorways of the Sea Coordinator, Kurt Bodewig, the second pillar of the three pillars of its strategy stresses the need to ensure smooth maritime transport by improving multimodal connectivity, and thus ensuring better connections to the TEN-T corridors and better links with neighbouring countries (European Commission, 2020). This programme was launched in July 2020. It reflects the principles of the new legislature of the European Parliament adopted in June 2019, and the guidelines set by the President of the European Commission, Ursula von der Leyen, and the “Green Deal” programme, which is already setting the agenda for all the countries of the Union. It is important to note that the transport sector has been dramatically affected by the measures to contain the pandemic. The continuity of services has been ensured by transport workers under challenging conditions, showing that their role is critical in serving the essential needs of the population. By extension, the transport sector will also be crucial in supporting the post-COVID-19 economic recovery. This will particularly rely on the maritime and port transport sectors, with cruise, ferry and Ro-Pax operators being the most affected.

The sector faces two significant challenges: on the one hand, an evolution towards a concept of mobility as a service, which implies the integral management of information systems and means of transport oriented to the service of mobility; and, on the other, and always under the same principles, synchro modality and the physical Internet. These challenges are two new ways of visualising freight and passenger transport in which digitalisation, and clean energies will play a fundamental role.

Conclusions

The transitions in the energy, telecommunications and transport networks pose a disruptive change in the transport sector. Companies will have to reconfigure their strategies because they will have to change their means to adapt to the new situation, and management systems will be increasingly based on the digitalisation of operations, with artificial intelligence applying to their day-to-day activities. This brings about new opportunities for companies and the entry of new players from different markets. These new players may have competitive advantages over the rest, something that has already been witnessed in other sectors. Mobility will continue to be a fundamental element in development but will be adapted to a new reality that has emerged from the COVID-19 pandemic. Companies will have to reconfigure many of the professional profiles to adapt them to the new reality and to favour the new skills that will be required for a circular economy. These are what we call “Blue Skills”. Training to cope with this transition will be a crucial factor in facilitating that transition.

Energy prices will change very significantly. Solar energy will gain prominence, giving a competitive advantage to countries with deserts, where solar energy performance is very high. This is an excellent advantage for the Southern Mediterranean countries. These price fluctuations will doubtlessly cause instability for a certain period.

Sustainability becomes the driver towards economic recovery. The challenge of building a new sustainable society will mark the agendas and efforts of the post-COVID-19 generation, which is much more open and aware of the challenges that we will have to face.

It is too soon to know how the COVID-19 will affect public transport. It still seems that the pandemic will last for some time, although more hope has emerged with the emergency approvals of the new vaccines in some countries, which should help overcome it. Transport will change, above all, because it already had to change with or without the COVID-19. It will do so with environmentally friendly mobility and be more adapted to serving people and goods thanks to non-polluting fuels and artificial intelligence digitalisation processes. Change is on the Blue Horizon ahead, so let us sail towards it sustainably together.

EU Bodies agree on Port Waste Facilities

Representatives from the Presidency of the European Council, the European Parliament and the European Commission have reached a provisional agreement on the proposal for the new EU directive on port reception facilities.

Ships will be allowed to deliver all garbage when paying a fixed port waste fee, without port-specific limitations towards the volumes delivered. This will guarantee that ports keep investing in efficient port reception facilities, which are to be supported by transparent cost recovery systems.

“This agreement is an important step towards the further safeguarding of the marine environment, the working space of our shipping industry,” said Martin Dorsman, secretary general of European Community Shipowners’ Associations (ECSA).

“By facilitating all ships to deliver their waste to adequate port reception facilities ashore, the EU is showcasing how we can halt the generation of marine litter. This contributes towards the United Nationals Sustainable Development Goals to prevent and significantly reduce marine pollution of all kinds.”

Global outlook

Although the directive mainly focuses on European ports and ships entering those, the EU legislators clearly recognise the importance of ensuring smooth operation of maritime traffic between EU and non-EU ports, stated ECSA. The organisation pointed out this is demonstrated by the alignment of the EU legislation with the IMO’s International Convention for the Prevention of Pollution from Ships (MARPOL), which has been amended since the current directive was adopted in 2000.

“We are looking forward now to take up the work again which started many years ago in the port reception facilities subgroup of the European Sustainable Shipping Forum ESSF and are eager to continue the good cooperation with the NGOs, the EU ports, the EU legislators and the Member States in a new expert working group,” emphasised Mr Dorsman.

Report: LNG Comparable to Other Fossil Fuels

There is no widely available fuel, including LNG, to manage climate change and local pollutants in tandem, according to a recent study by researchers at The University of Manchester.

The researchers carried out a life cycle assessment of current and future fuels used by the shipping companies to quantify their environmental impacts. The alternative fuels assessed in the study were LNG, methanol, liquid hydrogen, biodiesel, straight vegetable oil and bio-LNG. They measured the impacts of local pollutants (sulfur oxides, nitrogen oxides and particulate matter) and greenhouse gases (carbon dioxide, methane and nitrous oxide).

Fuels can incur the release of emissions at various stages of their life-cycle, for example during refining or transportation, or during the cultivation of the fuel if it is bio-derived. The latter may have impacts associated with cultivation, land-use change and agricultural inputs such as fertilizers. Although the upstream emissions are not attributed to the shipping sector, it is essential to ensure wider implications of fuel switches are accounted for, say the researchers. Failure to take upstream emissions into account in any sectoral assessment risks locking in carbon intensive solutions.

Dr Paul Gilbert, Senior Lecturer in Climate Change Mitigation, said: “In particular, LNG is a promising option for meeting existing regulation, but it is not a low greenhouse gas emissions fuel.

“To understand the full extent of the environmental implications it is important to consider the emissions released over the full life-cycle and not just during fuel combustion. Otherwise, there is a risk of misleading the industry and policy on the true emission penalties of any alternative fuels.”

The two conventional fossil fuels and LNG produce comparable baseline greenhouse gas emissions. When taking into account non-CO2 emissions, any reductions of greenhouse gas emissions in terms of CO2e are negligible for LNG, states the study. The main life-cycle hot-spots include liquefaction efficiency; extent of venting and flaring; and methane slip – the unintended release of methane during ship operation.

Even under idealized conditions, reductions of CO2 emissions are strictly limited. Bio-LNG produced from agricultural waste is an exception. The results show that it has the potential to cut CO2 emissions significantly. However, feedstock is limited.

The figure (sourced from the Journal of Cleaner Production) shows lifecycle emissions in terms of carbon dioxide equivalents, distinguishing between upstream and operational emissions.

The study says effort needs to be directed at overcoming barriers to exploiting the identified low carbon potential of fuels or finding alternatives. Gilbert said it is important to ensure that any short-term measure doesn’t diminish the potential roll-out of low carbon fuels, in particular when taking into account the long life times of ships and fuel supply infrastructure.
