So far, specific details are thin on the new battery designed for home use that Tesla’s announcing next week. But just based on what we do know, it’s a pretty big deal. The quest for a good battery that can store home-generated power is kind of like the holy grail for a renewable energy future. This one product might change everything.
A New York Times article published earlier this week essentially sets up the problem that Tesla’s battery will solve. In Hawaii, 12 percent of homes have some kind of solar energy, by far the highest rate for any place in the US at the moment. In fact, that rate is growing too quickly—solar customers are dumping so much energy back onto the grid that they’re taxing the delicate and often aging infrastructure that was only designed to deliver power to homes. What’s happening in Hawaii is actually indicative of what’s going to be an issue everywhere as many cities start to see an increase in large-scale solar implementation: There’s going to be too much energy generated, and nowhere to put it.
