Question because I'm not familiar: if you need water to make hydrogen, isn't that an issue in countries that are having water issues, like India?

- kristjank 4y agoI am not familiar either, but I imagine the answer is similar to the vegan argument against grazing cattle: not all water sources are made equal.
- xyzzyz 4y agoAs a very rough approximation (just to get a proper order of magnitude), to make enough hydrogen fuel through electrolysis to run a car, you need about as much water as you would need gasoline. Compared to daily household needs, it’s insubstantial, and compared to agricultural needs, it’s less than rounding error.
- ummonk 4y agoThe amount of water used would be minuscule, and besides, electrolysis is probably cheaper using sea water anyway. Water shortages happen because agriculture uses so much water, not because we don’t have much of it.
- kumarvvr 4y agoNot much water is required to produce hydrogen in the scale required. And, it can also be captured and recycled.
