While hydrogen’s deployment as an energy carrier is only in its infancy, this element already forms the backbone of many different industrial processes around the globe. In order to ensure hydrogen feedstock is handled as efficiently as possible, the ELCH electrochemical research cluster at DHBW Mannheim university is carrying out a pioneering joint project which is looking into hydrogen recycling by means of electrochemical compression. The focus of the EH2C project is on recycling hydrogen that accrues during the production of solar cells and other semiconductors. (more…)

According to European Union guidelines, carbon dioxide emissions from heavy-duty vehicles will need to be cut by 30 percent by the year 2030 in order to ensure emissions reductions are on track to meet the EU’s 2050 net-zero target. This would mean that around 200,000 emission-free trucks would have to be operating on Europe’s roads by 2030. That’s the finding of a recent study carried out by the association of German engineers VDI and the testing and certification institute VDE entitled “Sustainable commercial vehicles – a comparison of different technology pathways for carbon-neutral and carbon-free propulsion.” It found marked advantages for the use of fuel cell power systems for long-distance transportation using large commercial vehicles while battery-electric powertrains were seen as clearly beneficial for small commercial vehicles.

News on the H2 regulations by the DVGW

The tasks of grid operators include, on the one hand, the safety-oriented design of the gas infrastructure and, on the other hand, guaranteeing the proper functioning and operational reliability of the gas networks over their lifetime of use. Network operators ensure this by adhering to the requirements in the technical regulations of the DVGW, the German association for gas and water standards (Deutscher Verein des Gas- und Wasserfaches e.V.), for all gases in accordance with reference sheet (Arbeitsblatt) G 260. Which now also includes hydrogen. With the publishing of the new Energiewirtschaftsgesetz (German energy industry law, EnWG) in August 2021, the DVGW also became responsible for establishing the technical rules and requirements for the supply of hydrogen by pipeline to the general public. On the one hand, this is a leap of trust in the expertise of the gas industry and, on the other, an impetus to further develop the regulatory framework especially for hydrogen. (more…)

Dear Readers!

We could have had it so much easier. Everything we need today, we could have built and prepared long ago. But we knew, or at least suspected, that it might eventually come to this. The Club of Rome had prophesied exactly this scenario already fifty years ago. (more…)

The developments in the electrolyzer sector are continuing in great strides. Particularly in costs, where most manufacturers have been able to achieve substantial price reductions in the recent months, even if this has not been reflected in a reduction of the final price in all cases. In addition, both stacks and whole systems are becoming increasingly more compact and efficient. (more…)

Decentralized H2 plants can be economically operated

Up to now, Germany has had an energy supply system that’s as centralized as possible. Large power plants generated electricity and heat, which was then distributed nationwide by means of an extensively branched infrastructure. With the emergence of renewable energies two decades ago, the idea of decentralization became increasingly widespread: since local solar and wind power plants or biogas plants generate electricity or heat on site, this energy can be used locally, without the need for loss-ridden transports. This basic idea is now also being pursued with hydrogen production by electrolysis. Whether such an approach might be sensible was investigated by the Reiner Lemoine Institut in its newest study “Netzdienliche Wasserstofferzeugung” (grid-serving hydrogen production). The results were presented in an online press conference March 10th, 2022. (more…)
