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.

Automakers lose about $6,000 on every EV they sell

Electric vehicle intenders want 20-minute charging times, a 350-mile driving range and to pay $50,000 for a car, according to a Boston Consulting Group study. Only one EV on the market — the Hyundai Ioniq 6 SE RWD Long Range model — meets those thresholds.  

Automakers are losing thousands of dollars on every EV they sell, and for the most part not meeting consumer expectations for the vehicles, according to Boston Consulting Group.
