P2G systems use electrolysis powered by renewable energy to split water into hydrogen and oxygen—i.e., P2G converts electrical energy to chemical energy in the form of hydrogen. Constraining storage solutions to “electricity-in, electricity-out” only will increase the cost of intermittency.

In contrast, flow batteries can independently scale the power (electrode area) and energy (arbitrarily large storage volume) components of the system by maintaining all of the electro-active species in fluid form. The design permits larger amounts of energy to be stored at lower cost than with traditional batteries. Background.

The authors point out their study looked at only two criteria, kilometers travelled and greenhouse gas offsets, but did not examine the performance of electricity and ethanol for other policy-relevant criteria such as water consumption, air pollution or economic costs. “We
