Time to do right by future generations

Time to do right by future generations

by | May 14, 2022 | Germany

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

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…)

A consortium has shown that it’s possible to extract climate-neutral hydrogen from seawater. Involved in the SEA2H2 project are automotive and industrial supplier Schaeffler, the startup Hydron Energy, which joined the Schaeffler Group in summer 2021, and Wageningen Food & Biobased Research, or WFBR for short, which is in turn part of Wageningen University.

For the production of the 14 TWh of green hydrogen capacity the German federal government expects by 2030, no more water is needed than what a city with around 200,000 inhabitants consumes. This was the calculation of the DVGW (Deutscher Verein des Gas- und Wasserfaches), the German association for gas and water standards, in the study “Klimaschutz und Resilienz” (climate protection and climate resilience) from April 2021. According to it, the use of electrolyzers with comparatively low input of water is feasible. Electrolyzers also perform favorably in comparison to coal-fired power plants. For example, the water demand of the energy industry today, which is primarily coal-fired, is more than 50 percent of the total water withdrawal of Germany for the year 2020, according to data from the federal environmental agency UBA (Umweltbundesamt).
