My readers know that I have great optimism for the future of solar power. As the cost of solar cells drops, the challenge is to bridge the gap from sundown to sunrise. A recent article “‘Major Discovery’ Primed To Unleash Solar Revolution” suggests that “MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn’t shine.”
The article goes on to describe a low cost, low loss method used to split water into hydrogen and oxygen, in effect creating a household fuel cell. While this system may still be years away, it may provide the much needed storage solution once solar (and wind) power becomes economically viable.
