Over the past decade hydrogen has really taken centre stage in the search for an alternative fuel for maritime transport. Different applications of the gas have been researched and trialled in various maritime scenarios. The most recent and most successful case in recent years, without a doubt, has been the development and implementation of hydrogen fuel cells. In this #DidYouKnow article we take a look at this technology and consider its impact on the maritime industry.

Hydrogen Fuel Cells

Fuel cell technology has been around since the early 1800s. A fuel cell is an “electrochemical energy conversion device that was invented in 1839 by William Grove to produce electricity by combining hydrogen and oxygen into water” (GenCell Energy). Like regular batteries, fuel cell batteries can convert potential energy into electricity, and result in heat as a by-product. In the 1950s, in the heart of the Cold War arms and space races that took place between the USA and USSR, liquid hydrogen was explored as a powerful fuel and finally used to send rockets into space – taking it one step closer towards the hydrogen fuel cell.

In recent years this technology has been considered for freight transport journeys. As more and more research is being done on different sustainable alternatives to fossil fuels, fuel cell technology took centre stage. Using the example of green hydrogen to power ships, researches have adapted Grove’s traditional concept to be able to use hydrogen’s energy and convert it to electricity and heat, and therewith power the vessels’ propulsion mechanisms. In other words, hydrogen fuel cells combine hydrogen with oxygen, and therewith produce electricity. The hydrogen is sourced from a tank that is built into the cell, where it then reacts with oxygen that is “sourced” from air. The resulting chemical reaction produces electricity, water and heat. The water and heat are released as water vapours, and thus are considered zero-emission by-products.

The electricity provides continuous energy to the ships as long as the cell is fed with the “fuel” – in this case hydrogen gas. This proves to be an advantage over conventional electric batteries that have a fixed shelf-life or need recharging . Fuel cells generate very little noise pollution, can easily be modified for different-sized vessels, and have no distinct moving parts. There is a general consensus that the vast majority of vessels could easily be retro-fitted with this technology – therewith lowering the carbon footprint of the shipping industry.

Hydrogen Sourcing

 It is not difficult to understand why scientists are excited about such capabilities of hydrogen – as it is the most abundant element on our planet. However, it is rare to find it in its isolated form. It can found in water and other hydrocarbon chemical elements such as methane. In order for it to be used in hydrogen fuel cells, the element needs to first be isolated through chemical, biological or solar-driven processes. (An interesting side-note is that nearly 85% of hydrogen is already being produced daily in fossil fuel refineries during the processes of removing sulphur from gasoline).

There are sustainable sourcing solutions utilised by some companies in the world. Hydrogen can be produced using biogas, or through electrolysis that uses electricity generated by solar or wind power. Relying on such sourcing alternatives will help keep CO2 emissions low from the entire hydrogen fuel operation in the transport sector.

Sustainable Shipping

One kilogram of hydrogen has the same energy density as a gallon of diesel.

At the end of the noughts, the European Commission began to direct its policies more actively towards sustainable transport amid growing concerns related to climate change. In the 2008 European Strategic Energy Technology Plan, hydrogen and fuel cells were singled out as the new technologies that would help the transport sector achieve a 60-80% reduction in GHG by the middle of the century.

Because hydrogen fuel cells already exist, and don’t require a huge investment of shipowners to install them in vessels, they are being considered as a fore-runner in the field. William Alan Reinsch, Scholl Chair in International Business estimates that “hydrogen fuel could replace 43 percent of voyages between the United States and China without any changes, and 99 percent of voyages with minor changes to fuel capacity or operations.”

Currently there is already one hydrogen powered ship – the Energy Observer – carrying out a six-year trip around the world. In its virgin voyage, the ship uses solar panels, wind and wave turbines to power the process. Its success coud determine whether the method could prove efficient and effective for various ocean voyages.

Challenges to Hydrogen

It wouldn’t be prudent to assume that hydrogen was the faultless solution that would eliminate all GHG within the shipping industry – as it has some challenges and complications. Hydrogen gas is extremely flammable, and its chemical properties mean that it can burn at both low and high concentrations when combined with oxygen in an uncontrolled reaction. Shipowners need to make sure that important safety measures are in place to lower the risk of such explosions during their transport and storage.

An added complication that would need to be addressed is that the element (even in its liquid form) is very energy dense. This means that the fuel cells themselves take up more volume on larger vessels – potentially lowering the profitability of the voyages themselves for ship owners (with diminished cargo spaces on the vessels themselves).

Finally, the cost of the type of hydrogen sources is also important to take into account. Hydrogen Fuel Cells use so-called “Green Hydrogen” (there are three types – Gray, Blue and Green, with Green being touted as the most ecologically sourced) – which currently is the most expensive hydrogen available on the market. For the shipping industry to be truly sustainable, this is the hydrogen type that would need to be used, and therefore its costs would need to be adjusted to make it appealing to the private sector.

A Greener Future

There is no doubt that the path ahead for the shipping industry is difficult and full of unknowns. There is no one-answer-fits-all solution to try to eliminate GHG emission from the oceanic trades. Different solutions are currently being tested and are being developed at astonishing rates. More than one would need to exist for the goals set by the IMO for 2050 to be reached.

Hydrogen Fuel Cells are proving to be very effective and, if embraced by the shipping industry, could prove integral towards the goal of zero emissions maritime transport. Even though no giant vessels have embraced the technology, smaller ferries and ships have begun operating in the USA, France, Norway and Belgium. Moreover, “oil major Royal Dutch Shell has invested in several hydrogen production projects in Europe and China, arguing that hydrogen is “advantaged over other potential zero-emissions fuels for shipping,” as attested by William Alan Reinsch – a huge sign that even the traditional fuel sourcing companies are coming on board.

There is still a long road ahead, but with the continuous innovations from scientists and financial contributions from big players in the industry, the goal of achieving global net zero emissions by 2050 could, perhaps, be attainable. Hydrogen fuel cells could be responsible for a significant step in that direction.

Big Data is a field that extracts and analyses data from data sets that are too large or complex to be dealt with by traditional data-processing application software. But why does it matter to the maritime industry? For this month’s #DidYouKnow series we have prepared an infographic that details the main concepts that surround real-time data and maritime transport. 

Curious to know more? These and many other concepts are covered in our Motorways of the Sea course. Contact us to find out what are the upcoming courses this year.

#DidYouKnow: Spotlight on Algeria

In 2017 the Escola Europea, along with the Escola’s founding partners, has launched the MOS Magreb project. Its objective was to increase the cooperation between the countries in the North and South of the Mediterranean Sea. The project evolved into TransLogMed, which now counts with 42 partners from Spain, Italy, Morocco, Tunisia, Algeria, with the goal of incorporating other partners from Egypt in the future. The long-term objective of this project is to foster the development of the Motorways of the Sea between the Mediterranean countries, which will in turn help promoting inclusive growth and youth employability, as well as sustainable development in the region.

This month we have caught up with Mr. Mohamed Lazhar Benaissa, an academic at the École Nationale Supérieure de Technologie (ENST) in Alger, the deputy director for external relations and continuing education and a lecturer at the Escola Europea to give us an overview of the logistics scene in Algeria.

 

Logistics in Algeria

Algeria’s geographical location as the largest country in Africa, situated at the crossroads of important trade corridors (Europe-Africa, Mediterranean Sea), gives it the opportunity to play a major role in the field of logistics. To the north, Algeria has a 1,200 km long seafront overlooking the Mediterranean Sea and is home to 11 trading ports through which more than 95% of its foreign trade passes. However, this situation should not mask the numerous constraints related to the characteristics of these ports and their current organisation. According to the United Nations Conference on Trade and Development, the Maritime Transport Connectivity Index [1]for Algeria in 2019 is only 12.81/100, far behind countries such as Egypt (66.72) and Morocco (58.19).  This is because the ports are often of ancient foundation[2] and are located within large cities that have prospered without sparing the land reserves necessary for their harmonious development. Whether first or second generation, these ports are subject to simple load breaks and do not meet the criteria that characterise modern logistics ports[3]. Currently the feedering used consists of coupling transoceanic containerised traffic headed towards large European ports with short-distance traffic headed towards Algeria, which increases the transit time of inputs. This will subsequently see their time lengthening once again during the transhipment operations. This results in insufficient yields and malfunctions that generate incessant bottlenecks and yields additional logistics costs.

The Algerian fleet

As regards the Algerian maritime fleet, as of the end of 2017, it was made up of 16 (often) obsolete units distributed among :

  1. 8 bulk carriers, 4 multi-purpose vessels and 2 RO-RO vessels belonging to the public company CNAN[4],
  2. 1 RO-RO and 1 bulk carrier belonging to the private company Nolis, a subsidiary of the Cevital[5]group.

What about containerisation?

As for containerisation, which has been gaining significant market share value over the past several years, it has proven of great benefit to foreign shipping lines as, in the virtual absence of the national flag, it allows them to freely set transport prices. According to World Bank figures[6], container traffic increased from 2007 to 2018 from 200.050 to 1.465.800 TEUs respectively, which is equivalent to an average annual growth rate of 20.6%. Given this growth opportunity, it is not surprising that we are witnessing the establishment of international terminal operators in Algerian ports such as the Singaporean Portek in Bejaia and the Emirati DP World in Algiers and Djendjen.

Where is Algeria on the digitisation scene?

During port passage, the lack of a rapid information systems makes it difficult to forecast the capacity of goods to be loaded, which, in the case of temperature-controlled products for example, would keep them on the quayside without any guarantees of preservation and respect for the cold chain. At the time of writing, only the Algerian customs can use a computer system called SIGAD in order to speed up the customs declaration circuit. In its most recent version, this system has a risk management system that classifies goods according to 3 circuits: green, orange and red. In the green circuit, goods are not subject to examination. In the orange circuit, the control consists of a documentary examination and in the red circuit, a physical inspection of the goods is required.

What of intermodal transport?

In terms of land transport infrastructure, Algeria has substantial networks whose quality has improved in recent years. Nevertheless, the motorway network is still insufficient and the lack of connections to several ports bears a cost. The rail network, for its part, is still in the process of development in terms of quality and coverage.

Road transport logistics, which dominates 90 per cent of goods flows, is only slightly outsourced by companies, since more than 50 per cent of the market is still handled by own-account transport. There is currently a growing awareness of the advantages of using transport for hire or reward and outsourcing the transport function, and the opportunities for growth for this sector are ample.

The provision of road transport services has long been a public monopoly. The opening up of the sector in 1988 led to an atomisation of the sector through the creation of very small companies with vehicles of all ages and of varying condition. It is therefore more a question of small-scale, or even informal activities that risk increasing the financial and organisational risks and reducing the scope to optimise the services offered. Air transport plays only a marginal role and rail freight activity, which is already weak, has been in inexorable decline for decades and is limited to heavy goods transport. Multimodal transport is almost non-existent.

Distribution is dominated by wholesalers present in most economic sectors and in particular in agri-food products (beverages, sugar, etc.). Few of them follow known logistics models, such as Numidis of the Cevital group. Indeed, with the exception of large conurbations (Algiers, Oran, Sétif…), where large modern warehouses are beginning to appear, storage facilities are of modest size (from 2 to 4,000 m²), of old-fashioned design, lack functionality and do not have special equipment such as loading docks. The players are either industrialists (acting on their own account), wholesalers or retail traders.

Thus, logistics services are essentially limited to the subcontracting of transport operations.

Can you tell us a little bit more about the training situation in Algeria?

The current supply of training is insufficient in many areas, no doubt due to the lack of formal demand from the sector and a lack of impetus from the public authorities.

The Algerian authorities have been trying to improve the logistics situation since 2007, when the first master plan for the establishment of new logistics platforms was prepared. However, the implementation of the latter has not yet materialized. The other actions undertaken were :

  • The World Bank has been approached to prepare a logistics strategy and upgrade the legislative and regulatory framework, as several ministries and agencies are currently involved in logistics and are sometimes in conflict of jurisdiction;
  • The preparation of a project for the construction of a modern port in Hamadania about 100 km west of Algiers with a Chinese partnership;
  • Digitisation through the implementation of an electronic port one-stop shop. This will help unite the whole logistics chain of the ports and the segments that interact in its activities. It will also enable the digitisation of procedures and a better coordination and planning of port operations.

One can already wonder whether these actions will end up putting logistics in Algeria on the rails of modernity.

The Ship Agent

/in , , , ,

When we think about the arrival of a vessel to the port, the first thing we think about is the loading or discharging of the cargo. Even though this is not entirely incorrect, many ships have more specific requirements and needs upon arrival. This is where the role of the ship agent comes in, and this is what we chose to focus on in this post for our #DidYouKnow series.
