Many industrial countries already have lots of gas power plants. If they don’t actually need to run that often and don’t need that much fuel, just run them on hydrogen or biogas instead.
Near zero investments to be made. Just somewhat larger operational costs per MWh delivered.
If you collocate some industry that needs hydrogen (necessary for green steel and fertilisers for instance) then making and storing the hydrogen on-site should be fairly cost efficient.
Running hydrogen in gas turbines has been demonstrated already btw.
- kragen 2y agoright now only about a third of the 18 terawatts or so of world marketed energy consumption is electrical. to electrify the rest of the existing economy, we need to triple electrical generation capacity. since some of that new capacity will be intermittent sources like solar and wind (probably almost all of it) we also need to expand peaker plant or battery capacity, probably a lot, in order to supply essential uses that aren't amenable to demand response; the alternative is blackouts and deindustrialization if your peaker plants are gas turbines, running them less drives up their capex per megawatt hour delivered, so i'm interested in how much that capex is i agree that hydrogen is a plausible form of storage and can certainly be used for gas turbines
