You also need to account for grid scale energy storage to deploy renewables at any meaningful capacity. Unfortunately we still don’t have a cost-effective solution that works at grid scale. Batteries don’t last long enough.
- adrianN 5y agoPower2Gas works at grid scale, but I agree that it's cost should come down a bit more. Right now it's cheaper to shape the demand side in most countries than to invest into storage. However, I am also taking into account about 200€/ton CO2.
- jasonlaramburu 5y ago>Power2Gas works at grid scale You also have to consider round trip efficiency. Anything less than 75% is probably a non-starter. Lithium Ion approaches 93% but still has a very high cost of ownership.
- adrianN 5y agoWell yeah, poor round trip efficiencies are an important part of what makes power2gas expensive. I find it unlikely that we'll have enough batteries to cover cold, dark winters, so I assume that we'll won't get around power2gas completely. The infrastructure to store large amounts of gas is already built, so that is nice.
