If it’s not to be Gas or Nuclear, then most often mentioned is battery storage. Problem with battery storage is that it’s expensive.
How expensive? If we decide we need a week of stored power (we currently have only a few minutes of stored battery power around the world), that would cost around $300 Trillion over ten years, at the current battery energy price of $100 per kWh. That’s already a very optimistically low price, as it’s actually around three times that.
At the end of the video above, Matt answers “why haven’t we been using this type of battery more widely?” Which is: price. He suggests that at the price might drop to $100 per kWh. Might.
In which case it would still be hugely expensive to have battery back up. More than Nuclear and way more than Gas. My own, sitting-on-the-sidelines guess: go for Gas. A bit pricier but greener: Gas with Carbon Capture Systems.
