Still seems like this is a big guess that sequestration works over long periods, or at all at the scale necessary to be industrially significant. I’m inherently sceptical of anything hydrogen related due to the fuel’s association with delay tactics from the carbon industry. Chevron would prefer we all not buy electric cars in hopes of HFC becoming a real thing which, obviously, is just a farce to keep paying them to produce, transport, and sell solid fuel. I think we are better off as a society not burning carbon at all, not looking for places to put carbon polution.
