Haven't heard much of hydrogen fuel cells in a while. Maybe trains would easier from an infrastructure point of view, although anything that increases the cost of trains still further is unlikely to be popular.

The trouble is creating the hydrogen takes about twice as much electricity per mile than just using the electricity directly.
ReplyDeleteAdrian Chapmanlaw Fortunately, Germany has clean, non-polluting coal energy for that. Good thing they renounced to those high-emission nuclear plants!
ReplyDeleteElie Thorne nuclear isn't the answer either, wind, solar, hydro, batteries, vehicle to grid etc etc etc.
ReplyDeleteAdrian Chapmanlaw Nuclear is a good a stopgap as we have until better stopgap can be found with affordable large-scale batteries, solar panels that don't leave toxic waste for the next generation, windgens that don't hate the local environment and thorium powerplants - which can in turn help us until fusion and space solar start working somewhere in the next century.
ReplyDeleteElie Thorne if every house hold in the UK had solar, battery and a air source pump we would be 90% of the way there
ReplyDeleteAdrian Chapmanlaw Which would require cheaper batteries (lithium reserves aren't infinite - let's hope sodium holds its promises) and either solar panels that don't leave toxic waste at the end of their lives or some pretty good recycling industry in a few decades. Doable, but we're not quite there yet.
ReplyDeleteAnd also a competent government that can create and enforce the right policies in order for the whole gigantic project to be done. Well, science-fiction it is, then.
