Compressed Air Energy Storage (CAES) has been hampered in becoming a leading sustainable storage technology, owing to a need for natural gas as part of the process. With newer technologies in development, it may be possible to skip the fossil gas step.
Above, see a profile of a newer technology, significantly backed by Oil Giant Total.
Below, a snapshot of the existing technology with gas input.
Am willing to be educated! Trying to see significant energy out of these things make my head hurt. Storing heat from the compression process for seasons for example.
Until further notice, this and other PLANS are public relations exercises.
This is just a lot of hot air! Don’t sell your Solar Roadway stock yet!
