It uses the same power as a AA battery, according to the article.
The other nice thing is that the carbon slurry that is left over can be used to create graphene.
The energy requirements were low enough that the researchers could power the reaction with one standard silicon solar cell generating roughly 15 milliamps of current at 0.5 volts. That’s less than the amount of power produced by an AA battery.
“It’s very efficient, with almost 35% conversion of the biochar and solar energy into hydrogen,” said Rohit Chauhan, a co-author and postdoctoral scholar in Singh’s lab. “These are world record numbers; it’s the highest anyone has demonstrated.”
