Maybe not actually powered by renewable energy but potentially so.
- zejn 5y agoOrkney is known to have an abundance of community wind energy, which they are unable to export to Scotland due to cable capacity limitations. They're experimenting with H2 generation instead.
- ncmncm 5y agoThere will be good reasons to produce NH3, as well. But that also needs H2. H2 is not a super-great long-term storage medium. NH3 is a good choice to use to fuel retrofitted transport shipping (which would just need new tankage and plumbing, not new engines) and to drive generators in places where solar is not practical much of the time, such as north of 55 degrees latitude.
- tonyedgecombe 5y agoNH3 = Ammonia.
- azornathogron 5y agoI wonder why they don't experiment with a bigger cable... Are grid interconnectors much more capital intensive or higher maintenance than Hydrogen generating plants? (Genuine question - I have no idea of the relative costs here)
