Grid storage large containerized batteries is a great idea too. There's even a local company (Aspin-Kemp) that makes them and also marine hybrid boats. The electric company here is a dinosaur wanting gas turbines and no interest in renewable energy just profits for shareholders. They even got caught with their pants down after a hurricane trees fell on power lines due to no tree maintenance for 40 years.
One issue with large battery storage is fires. Where I live is small and island with small towns the biggest city is at best 50,000. The next smallest city of about 15,000 uses grid storage batteries one of which recently caught fire and burned for a week. It's in a small town so the toxic smoke was a big problem. It would be very bad for a home battery system to ignite that's likely why my city does not allow home batteries inside homes.
A new method to douse battery fires needs to be developed. A week long fire and toxic smoke is very stressful.
