The most sensible solution is synthesised natural gas. Then we can use the existing LNG storage and plant.

It’s a lot easier to store and transport than hydrogen and the capital items already exist.

Curtailment fees should be replaced with purchases of green LNG.

The problem with that is how dispersed carbon atoms are in the atmosphere.

Another option is ammonia, which is quite nasty to deal with.

We can start with non-dispersed carbon atoms coming off industrial processes. Green hydrogen and CO2 into methane

It's more expensive than hydrogen because you need to capture and store the CO2 of combustion. Extracting CO2 from the atmosphere as part of the cycle would be even more prohibitively expensive.
