AFAIK because there is no other basket (hydrogen, the more promising, is far behind electricity, mainly because it is difficult to distribute and store).
- causi 4y agomainly because it is difficult to distribute and store Untrue. Energy losses in hydrogen storage and transmission are significant (11%) but much smaller than the losses at the electrolysis step (24%) and the redox step (46%).
- mywittyname 4y agoHydrogen is largely produced via steam reformation, making it a natural gas powered battery that's shittier than electricity in almost every way.
- natmaka 4y agoThis is at best not very pertinent, for many reasons. 1/ Losses vary according to the way the hydrogen is produced then used, and there are multiples paths. Overview: https://assets.siemens-energy.com/siemens/assets/api/uuid:5342163d-2333-4c8d-ae85-2a0e8d45db56/white-paper-efficiency-en.pdf https://assets.siemens-energy.com/siemens/assets/api/uuid:53... Moreover there are ways enabling a very high yield, for example high-temperature electrolysis (some recent gas turbines can be fed with a gas-hydrogen mix, up to 100% hydrogen) 2/ This is about green hydrogen ( https://en.wikipedia.org/wiki/Green_hydrogen https://en.wikipedia.org/wiki/Green_hydrogen ), therefore the electrolysis step is done thanks to electricity over-produced by renewable sources (without burning any combustible no producing any waste). Consequently the total cost of those losses are very low, as not using this overproduced electricity would lead to lose 100% of it.
- carom 4y agoLos Angeles recently banned gas stoves. We are most certainly heading toward single basket homes. Another example is that new construction can not have wood burning fireplaces.
- whimsicalism 4y agoThe air pollution in these regions due to fireplaces & cars is ridiculous, I don't think they are banning these things nationwide.
- carom 4y agoThe air pollution from gas stoves is a fraction of a percent of cars. I have not done the math on wood fireplaces.
- whimsicalism 4y agoWood fireplaces are definitely significant. I lived in a high hill on SF and think many don't realize quite how much haze is generated here on colder days. I specifically omitted gas stove, not sure air pollution is the reason for that one.
- carom 4y agoWood does release other particulate matter, but in terms of carbon (and climate change), burning a few logs is the equivalent of many people's daily commute. I'm not advocating for using this as a primary form of heating, but in the case of emergency, I would love to be able to heat my home with wood.
- jstarfish 4y agoNew York also banned gas stoves. You can expect more urban areas to follow suit; things are moving that direction because of the fire/explosion hazard in densely-populated areas.
