carbon neutral is absolutely good enough. Why the hell wouldn’t it be?!
H2 (or green electricity) is carbon negative when it displaces FF use. unnecessary and expensive efuels are not. DAC is/can be carbon negative. But sequestering the CO2 is less expense than combining it with H2 into an efuel that negates the capture value of DAC. A carbon tax and dividend is a better social mechanism for cost (including climate cost) reductions even when investing in DAC reduces the tax collections and dividends.
throwing out all the liquid fuel infrastructure
A misunderstanding, that stems from extreme volume of disinformation, is that energy transition means “first we have to nuke all infrastructure from orbit” strawman, that is used to protect the status quo. Instead, less then no new dead ender energy infrastructure investments should be made during transition, and then one day, fairly far away, old inefficient machinery will not be worth repairing, even though access to fuel will continue existing for a very long time, and no matter how inneficient it is, a machine will be sold for something greater than 0 to someone who needs it for backup, or because it is cheap.
Just because you can’t hold H2 in your existing beer mug container doesn’t mean H2 handling is not a largely solved problem. Ammonia is higher energy density than liquid H2 with propane container handling solutions.
