NASA Battery
What do you do if a satellite runs out of batteries? It’s prohibitively expensive to send a team into orbit and pop in some new AAs, and as a result many satellites use very efficient, reliable and long-lived nickel-hydrogen batteries. We’re talking about batteries that last decades. That sounds like the sort of battery that could revolutionize grid-scale energy storage and really help out renewables back here on Earth, which is why EnerVenue is backing nickel hydrogen batteries as the next step forward! But if batteries rugged and powerful enough for spacecraft already exist, then why haven’t we used it back here on Earth until now?
