Well first of all energy storage, is not production, but as you asked:
1) Reduced need for energy storage. Right to repair for everything, write code that is efficient and lower power, distributed systems which don't require complex centralized systems to run. Taxes on unused compute cycles to help create incentives for this, perhaps.
2) For actual energy storage, something like the sand heat system recently put into use in Scandinavia, or the mechanical earth dams (store energy in potential energy mass, less dangerous than an actual water dam, a lot easier to build). For immediate electric storage at scale you can do e.g. saline water storage tanks which hold mild electric charge, who knows maybe there is some inert chemistry which could be devised for a safer transportable version of a lithium ion battery...
3) For energy production, I am a long time advocate of geothermal. There's no real downside, besides digging holes and I guess maybe a well collapse, but you're limited to loss of whatever is in the whole/immediate surrounding in the case of a cave in, there are no engineering problems to solve except pumping water around, which is a well known task. Solar/wind for ships, airplanes, space vehicles, electric/hydrogen for storage/consumption scenarios where the grid is not accessible (remote locations e.g. the poles, alaska, siberia, African/Asian planes)
Its a company with as I understand it proven designs.
Besides, the concept is trivial and applicable and replicable by almost anyone. I don't understand why there is so much skepticism around these things...
This is a really lazy response, but given the possibility that you genuinely don't understand the gp: Writing better software and reducing the (currently massive) waste of energy on enterprise bullshit and cryptomining would have a meaningful impact on international energy usage, and so help climate change.
It's marginal compared to the other power expenses to be sure, but computing is another rising power cost. Besides my AC, and cooking, I don't have any regular power expenditures other than digital devices, so it seems reasonable to me to want to optimize power expenditure there.
Regarding the distributed vs centralized, the reasoning is large data centers are inefficient and could be replaced mostly with local, low power systems which are barely on at all, versus constant-on, constant-ready server rack systems.
