Its important to qualify that:
A decade or so behind, in the US.
If the US didn't block import of Chinese tech, we could have electrified a decade ago.
The tech available at the current moment, is even more capable of replacing petroleum based electricity.
But our government is banning Chinese tech to serve our outdated industries instead of importing it to serve the population.
As any wise country would do when faced with superior technology, we should import it with the condition of technology exchange. Chinese manufacturers should be training US workers and industrial ownership how to produce cheap, efficient, sodium batteries.
This benefits the populous immediately, and the industries are able to advance into the current century's tech.
All fine and dandy until your grid goes mysteriously offline the day after China moves on taiwan.

It protects American companies who operate in the green energy generation and storage arena from Chinese competition.

If it were a matter of industrial protectionism against a country which was not hostile, not authoritarian, didn't rely on slave labor, etc., then I'd agree with you. Countries have other pressing reasons besides immediate economic advantage to prevent this sort of thing.
To greatly oversimplify: Japan fought against opening their markets, as did China, out of political and social concerns for the stability of their states, far more than economic ones.
