An MIT research team had what they describe as a eureka moment when they discovered an inexpensive catalyst that can be made from cobalt and phosphorous, which dramatically reduces the amount of electricity required to split water into oxygen and hydrogen. Why is this a big thing? If the technology is scaled up, then it would not only be a cost-effective, environmentally-friendly way to store solar power, but also a clean way to collect hydrogen and oxygen as fuels.
