Long-term storage needs, ‘green gases,’ & the energy transition

by Todd Davidson

“There are times when it is really not windy, or is cloudy, for days or weeks on end.  If you shift to a high renewable world and have one of these weather patterns, I am not sure lithium-ion batteries are not the right solution for this kind of grid-scale storage. One of the potential other solutions is ‘power-to-gas’ (P2G). P2G is less energy-efficient than a battery. But when you start to talk about decarbonizing other sectors of the economy, P2G may be a potential solution there.”

 

“If you want 100% wind, water and solar, we’re going to need a lot of storage. And that storage is going to be very expensive.” If we can get creative and figure out how to leverage the existing natural gas infrastructure to distribute hydrogen or renewable methane, now we’re on to something. At least it needs to be part of the conversation.”
