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.
A stable energy supply in the future can only be ensured with the storage of energy on a large scale. On the basis of the liquid organic hydrogen carrier system (LOHC) and with the aid of PEM electrolysis and solid oxide fuel cells, the dimensions and above all the capacity of a storage power plant to replace…
Natural gas and hydrogen have much in common, but can a gas power station be adapted for hydrogen use? One organization that has been trying to answer this question since the summer is the Vattenfall energy corporation. In partnership with Gasunie, a Dutch gas infrastructure services business, and Statoil, a Norwegian oil company, it aims to examine whether a retrofit is technically feasible.
Construction of MEKS, Sperenberg’s multi-energy power plant, now entirely hinges on state government approval. In mid-July, the mayors of the four German towns involved signed a contract for the establishment of a community working group. But whereas local authorities would certainly welcome MEKS, the ones at state level have put a hold on the project, saying the selected area was not suitable for the construction of wind power facilities.
At the end of April 2015, GP Joule began testing its electricity fill-in concept. As part of the 200 kW H2 biogas project, the engineers at the head office of the company in Reussenköge, Germany, installed two electrolyzers, each with 5 kW stacks. In May, the plant was extended, with 16 additional stacks initially being installed. By the summer of 2015, the first four stacks were set to be replaced with a total of 24 new modules so that the nominal output then totals 200 kW. This enables
