Hydrogen batteries vs. lithium-ion batteries
Researchers in Australia have compared the technical and financial performances of a hydrogen battery storage system and a lithium-ion battery when coupled with rooftop PV. They evaluated two commercially available systems – LAVO and Tesla Powerwall 2 – and found that the lithium-ion battery provides better financial profits, whereas the hydrogen battery offers more battery lifespan for long duration of energy storage.
