>> perhaps we can make liquid fuels out of H2

> You're describing hydrocarbons.

This is technically correct, but at the right pressure, it becomes politically incorrect.

Right now there is already a huge push against fossil fuels, to the point that countries are setting dates for forbidding internal combustion engines in cars. Note that this will take effect independently of the source of fuel, fossil or otherwise. And methane, which is relatively easy to produce from bio-waste, it is a potent greenhouse gas.

For now, the public is divided. Nobody likes the consequences of global warming but nobody likes to give up the convenience of hydrocarbons.

Give it some time or add some more climate shock, and the public may change opinion to be against all fuels that contain some form of carbon, no matter the origin.




The problem is cost.

Technically it is quite possible to produce hydrocarbons today. In theory a government could mandate, for example, 25% green hydrocarbons in fuel in 2030.

In practice, nobody will do that because that is political suicide.

The good thing about the current BEV cars is that over the lifetime of the car they are cost effective. I will be disruptive for a while. But we now have enough experience with BEV cars to know that they are a practical solution.

Telling people that they can keep driving ICE cars in the future, without telling them that green hydrocarbons are going to cost a fortune and would prevent everybody except some rich people from actually driving ICE cars does not help.

Of course, that could all change if we can find a cheap way to make green hydrogen at scale. With current technology we need to get rid of ICE cars. We can always revisit that if green hydrogen becomes abundant.

Personally I would also be happy if all burning of hydrocarbons gets removed from cities. There is no reason to keep breathing exhaust gasses other than that the fuel is cheap.


ICEs in cars hurt local air quality and cause significant noise pollution. Even if you eliminate the fossil fuel aspect, it's still worth switching to EVs.

Aeroplanes have no viable alternative right now, and the noise/particulates issue aren't as big of a problem unless you live near an airport.

Nobody wants to give up the convenience of personal transportation using automobiles. And for the United States, a good chunk of which was designed around that this is a serious problem.
