Currently they run on heavy fuel oil – a substance that is more reminiscent of tar than vehicle fuel. It’s the residue that remains after various crude oil distillation processes have been carried out. While the more volatile fractions such as ke

rosene, gasoline, diesel and household fuel oil are separated off for other uses, the large, robust two-stroke engines of ocean-going giants make do with the leftover black sludge which is so viscous it needs to be heated up before it can be combusted. The changeover to fuels like liquefied natural gas, LNG, has already begun but this in itself won’t be enough. That’s why an increasing number of industry players are looking to hydrogen and are now making initial attempts to embed this fueling option in seagoing vessels. (more…)

The production of ammonia for the fertilizer industry is, according to the IEA (International Energy Agency), the second most important area of hydrogen utilization. We therefore presented some concrete projects for the production of green ammonia in the July 2021 issue of H2-international. But what about the user side? Up to now, ammonia has hardly played any role as an energy carrier, although it could become an important source of energy, especially in transport by ship. The compound has numerous advantages over other energy mediums. At the same time, however, there are still many technical and logistical challenges to be solved, which are being addressed by, among others, the research projects ShipFC and Campfire. (more…)

The joint venture between ElringKlinger and Plastic Omnium has built up a production capacity of 10,000 stack units per year at the Dettingen site. According to chief finance officer Dr. Gernot Stellberger, the fuel cell manufacturer from Baden-Württemberg has a lead of about two years over the competition in the area of industrial stack design. The company is aiming for a sales revenue of up to one billion euros by the end of the decade. In addition to the commercial vehicle sector, there is great interest from the maritime and rail industry. In the joint venture Aerostack with Airbus, EKPO Fuel Cell Technologies GmbH is developing a stack for use in aviation. (more…)

Instead of by electrolysis, hydrogen can also be produced photochemically. A research team at Universität Ulm has developed a molecule that stores energy from light by holding onto electrons released by another molecule. The hydrogen can then be produced with this stored energy at a later time as needed. (more…)

The trend is clear: refineries also need to become greener – recently also to limit the use of Russian oil and gas. In Germany, refineries are responsible for about a fifth of the CO2 emissions by the sector. Green hydrogen can be integrated into existing production processes. Several refineries are currently making this transition. (more…)

The production of green hydrogen is reliant upon electrolyzers being fed solar- and wind-generated electricity. Since these energy sources are fluctuating, and therefore not always available, a different approach and control mechanism is required compared with conventional power plants. At the RefLau model power plant in the area of Lusatia, work is underway as part of a grant project to analyze, initially on a small scale, how Germany’s energy supply could be controlled in the future.
