The idea that we could extract hydrogen cheaply from biomass - literal 'bionic duckweed' - is unrealistic when you think about the difficulty of extracting hydrogen from anything. It is typically an energy-intensive process that creates a gas that is then extremely difficult to store or transport. It would be brilliant if we could use hydrogen - which when burned, generates only water - to power more stuff. But it is very far away from being practical.
In the transportation sector, unfortunately, there is an awful lot of bionic duckweed. Electric cars, for all their fault, are not bionic duckweed. They are very real bit of technology that do, on the important measure of carbon emissions at least, starkly improve the damage done by cars to the environment. But much else is. Chief among them is the idea of autonomous, 'self-driving' cars.
For every electric vehicle the manufacturers sell, they lower their fleet-wide average a bit. That, in turn, frees them up to sell another monstrous petrol-burning SUV. [...] They do not even have to sell the electric cars themselves. In the first quarter of 2022, other automakers in the United States paid Elon Musk's firm $679 million in credits that it earned from overshooting the overall fuel efficiency targets, or about $2,200 for every car the firm produced. Every Tesla on Amerca's roads creates a little bit more regulatory space for another Chevrolet Suburban. Before 2022, Tesla was making more from selling the right to pollute to other car firms that it was in profit from selling its own cars.
