The electrolyzer storage in Picea refers to the integrated electrolyzer and hydrogen storage unit. The alkaline electrolyzer (70–80% efficiency) produces hydrogen from water using surplus solar power, which is then stored in dedicated tanks. This combined system eliminates the need for external hydrogen infrastructure, making it suitable for remote or grid-constrained locations. The electrolyzer operates in conjunction with a battery to handle short-term energy fluctuations, while hydrogen storage handles long-term needs. The Picea 2’s compact design (70% lighter than previous models) further optimizes space for integrated electrolyzer-storage units.
