In a cruel twist of irony...gasoline and diesel and similar short-chain hydrocarbons are about as good as it gets. We're always going to need significant quantities of hydrocarbons -- for fuels, for feedstocks for plastics and fertilizers, for lubricants, and more. And making syngas, a good base from which the rest can be refined or synthesized, from nothing but atmospheric CO2 and water and energy input, is ancient technology. The only problem is that it's energy-intensive -- which is to be expected, since it takes at least as much energy as is released from burning hydrocarbons, plus all the various inefficiencies. The ideal way forward is with grid-tie rooftop solar that primarily directly powers stuff right there, including BEVs, and the excess going to the grid first for others that can use it that moment, and any remaining surplus (which, of course, at time will be significant) going to manufacturing hydrocarbons from atmospheric CO2. Local battery storage will likely be the economic preference for overnight needs, with existing natural gas (etc.) power plants burning the fuels made during the day making up the difference. Most of the fuels made during the day, though, would go to plastics and fertilizer and jet aircraft fuel and the like. The way we're _actually_ headed, though, thanks to the idiocies of the electric utilities, is rooftop solar without the grid. That gets us oversized local systems with surpluses going to waste. b& -------------- next part -------------- A non-text attachment was scrubbed...
