John Petersen One of the most fervently debated and poorly understood topics in energy storage is the subject of battery recycling. What percentage of the raw materials that go into a battery can be economically recovered from used batteries with existing recycling technology and infrastructure? While the details are quite complex, this article will offer a high-level overview of the economics of battery recycling for energy storage investors. Lead-acid batteries are the most recycled products in the world. The process is both straightforward and cost-effective. When batteries arrive at the recycling plant, they're put through a shredder...

Thin film can also be productized in ways no panel can. It can be turned into something retailers can sell or bloggers will...
