For roughly the last month or so, I’ve danced all around the subject / title of this brief paper with the posts referenced below. However, I’ve seemed to do this without bringing these together, as this post will do.
So what is a hydrogen hub? It is a major user of green hydrogen that will use renewable electricity from the grid to produce adequate supplies of green hydrogen via an electrolyzer and store this hydrogen in high pressure tanks. The storage might have several functions:
- The electrolyzer can be sized based on average demand rather than peak demand.
- Storage potentially disassociates times of production and use to allow the electrolyzer to use the least-cost renewable electricity for the former when it’s available.
- Stored hydrogen can be used for backup when there is an electric outage.
