But these things have already been researched for some time. More than being researched, they have been put into practice. And this has already shown us that they are relatively expensive and hard to scale, while hydrocarbons are cheap and scale well and are not subject to much in the way of political risk or NIMBYism. And this will continue to be so for decades at least.
