Hydrogen compression energy loss
Web5 mei 2024 · There are four attractive options. Three will use shipping: ammonia, liquid hydrogen, and liquid organic hydrogen carriers (LOHC). The fourth is compressed hydrogen via pipelines, either newly laid or through upgraded existing gas pipelines. Scale-up saves money, so the minimum scale required is part of the calculation. WebWhen hydrogen in a combustible and explosive composition is compressed and stored for such technological development, the process must be well controlled to eliminate compression heat, static electricity, and catalytic substances, and at the same time the process should be done after substantiation and verification of sufficient safety.
