Hydrogen is considered the ideal raw material for a sustainable energy market transformation. However, some questions still await answers. Where will we get our hydrogen? Will we use the gray, blue, turquoise or green variant in the distant and not-so-distant future? Green hydrogen is produced using renewable energy sources and often generated via water electrolysis.
Micro-organisms provide more flexibility than common catalysts, and the methane produced by them is relatively pure. Additionally, the investment costs for Power-to-Gas systems can be lowered by using transformers and power as well as gas network connections of already existing biogas and wastewater treatment plants. This field of study, however, still requires more research to be done, even for
Greenpeace Energy presented a new study in August of 2015 according to which “wind gas” (gas produced with the help of excess power from renewable energy – hydrogen or methane) could contribute to strengthening the transformation of the energy sector. The 97-page comparison of future power supply with and without
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
