Why is it more plausible than heat pumps? We don't have infrastructure to ship hydrogen the way we do natural gas. It's not like one can use the same pipes.
Why are heat pumps not plausible? You can get them today.
- jl6 5y agoThe UK is replacing its metal pipes with plastic pipes: https://piperepair.co.uk/2020/08/04/pipe-replacements-to-cut-britains-gas-networks-carbon-footprint-by-two-thirds/ https://piperepair.co.uk/2020/08/04/pipe-replacements-to-cut... Aside from the cost (which might come down), heat pumps have some inherent disadvantages - reliance on insulation, and slow ramp up time. So no more opening the windows at night for fresh air, then getting the house back up to temperature in the morning.
- 0ldskool 5y agoEverything you described would be a problem with hydrogen as well if not more so. You would need much much more insulation + special pipes for hydrogen usage. I don't know about slow ramp up times, I've never heard this. It takes mine about 10-30seconds for a 3 story house to start up. "So no more opening the windows at night for fresh air, then getting the house back up to temperature in the morning." I don't understand, how does hydrogen solve this problem? How is this not a problem for other sources? Random note: I'm all for heat pumps & all for hydrogen. They just aren't for the same use cases. Heat pumps are good for heating+cooling of spaces. Hydrogen is good way to store electricity when care about energy-to-weight and/or need quick fuelling.
