This makes all of zero sense, especially for a forum populated by engineer-types who are familiar with turning abstract ideas into tangible and highly scalable applications.
A subset of users who use a ton in % terms, and can be targeted cleanly and clearly to change use, translates into a large % decrease with the minimal amount of work.
You are suggesting a waterfall-style approach. Toil for years because it’s harder?
- bryanlarsen 4y agoIf we want to get rid of all gas furnaces within 20 years, we have to start now if we want to do it the cheapest way. Furnaces have a 20 year lifespan, so if we install any more gas furnaces in the future, we'll have to rip them out before end of life. Instead, whenever a furnace needs replacement, put in a heat exchanger. Gas generators OTOH have a 50 year lifespan. They'll have to be ripped out prematurely.
- ZeroGravitas 4y agoModern Gas turbines can run on Hydrogen, and/or blends of Hydrogen and Methane. So they dont need ripped out, just better fuels.
- pfdietz 4y agoYou might have to replace the combustor.
- bryanlarsen 4y agoAnd all of the valves, inspect all of the welds, et cetera. Hydrogen leaks through everything. Just ask NASA why SLS hasn't launched yet.
- pfdietz 4y agoIndustry around the world manipulates 70 million tonnes of hydrogen a year, so I think they have this valve thing figured out.
- bryanlarsen 4y agoThat's not very much, about 0.1% of natgas consumption. And the vast majority is used immediately upon production and not transported or stored. But yes, there are lots of good hydrogen valves out there. Old natgas valves aren't good hydrogen valves.
