And yes, the first try at this typo'd 119 as 199. Sorry!

On hydrogen - @BloombergNEF research (June 2017) concluded that we could use it for seasonal load shifting/smoothing at a cost of 244 euros per MWh shifted, using electrolysis + fuel cells. With a visible tech pathway down to 119. (Short thread).

244 euros or even 119 euros per MWh is expensive power, but it's not totally ridiculous to cover the last 10-20% of grid decarbonisation. So we're not totally dismissive of H2 for seasonal load shifting long term.

It's a bit hard to see nearer term applications though. Fuel cells are high capex too, so you need to be using them a lot to make it worthwhile for home heating. And H2 vehicles are fast losing to EVs.

Key assumption: electrolysis is done when electricity on the German spot market is priced below average (32 euros/MWh) - electrolyser ends up running at about 51% utilisation, using power at average price of 16 euros. Utilisation really matters because electrolysers aren't cheap.

Perhaps we can afford this for the last 5% of grid decarbonisation. would hope intelligent vehicle to grid charge logic would allow us to harness a massive mobile battery storage to meet another 10%. /1

With Demand side management meeting the remaining 5%. A suite of smart grid levers should be more economic than any one technology. /2

Thanks for quantifying this for us. These sort of “how much would it cost to decarbonize in X way” estimates based on actual price and CF estimates are really valuable for informing discussion.
