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.
Both hydrogen batteries and lithium-ion batteries have been identified as promising stationary energy storage solutions for integration with rooftop solar systems. However, while lithium-ion batteries have been widely installed by both homes and businesses, hydrogen batteries only started to take off in 2021 with the world’s first commercial deployments by Australia-based startup LAVO.
Both technologies have their pros and cons. Hydrogen batteries have around 40% lower roundtrip…
