It's an interesting paper but I think most of the limitations in H2 production are in electricity supply, not in water supply

- ncmncm 4y agoElectricity supply cost is plummeting. Water is plentiful, but pure enough water not to foul electrolysers has not been, and efficiency has been low. Avoiding liquid phase bypasses all the difficulties of existing electrolysis.

- s1artibartfast 4y agoSource? From what I've seen Electricity wholesale costs increasing for the last 8 years. Yes there are times of the year where the spot price is low, but the average cost continues to go up.
- ncmncm 4y agoCost is still dominated by natural gas price. As solar and wind build-out saturates in coming decades, mined gas will become unable to compete with renewables and hot storage, most places.
- s1artibartfast 4y agoYour parent post was present tense, not future. Prices today nor the last several years have been plummeting.
- ncmncm 4y agoIf you built a solar farm last year, build another today, and another one next year, the cost for those will be seen on a sharp downslope. There would be no need ever to pay spot market price: you operate when you have power to operate. You could put up wind turbines too if you wanted to operate more regularly. In any case you can't buy these things yet. All costs are necessarily referred to a time when they are available off the shelf.
