It’s not the first time someone has tried to use hydrogen storage for making homes energy self-sufficient. The latest company to make the attempt is Home Power Solutions, based in Berlin, Germany. When HPS unveiled its Picea unit in March 2017 at the ISH in Frankfurt am Main, the press seemed to be all over it. This may have had something to do with HPS’ former parent company, Heliocentris, having filed for bankruptcy shortly before the trade show. H2-international sat down for an interview with the managing directors of HPS during Hannover Messe to talk about the company’s history and new developments.
