The article highlights the progress and challenges surrounding the production and adoption of green hydrogen in Europe. Despite obstacles such as political and economic setbacks, Europe is witnessing advancements in green hydrogen through subsidies, investments, and operational projects. Lhyfe in France secured a $169 million grant for a water electrolysis plant in Normandy, while Hy2gen in Germany raised $53 million for its renewable hydrogen production. OMV in Austria also initiated a 10MW green hydrogen plant near Vienna for sustainable aviation fuel and renewable diesel. However, criticism exists regarding the reliance on renewable energy credits instead of direct renewable energy sources, potentially leading to a significant net CO2 footprint. Joe Romm, a climate researcher, points out that the cost of producing green hydrogen has not decreased as projected, and alternative technologies like heat pumps and batteries may offer more effective emission reduction. Despite these challenges, the industry continues to make strides towards sustainable hydrogen production and utilization.
