EU Project Aims To Switch Data Centers To Second Hand Car Batteries 87

judgecorp writes "A €2.9 million European Commission funded project aims to make data centers more efficient, and one of its ideas is to use second hand car batteries to power data centers. The GreenDataNet consortium includes Nissan, which predicts a glut of still-usable second hand car batteries in around 15 years, when the cars start to wear out. Gathered into large units, these could store enough power to help with the big problem of the electricity grid — the mismatch between local renewable generation cycles and the peaks of demand for power."

    Perhaps you're thinking of lead-acid batteries used in conventional ICE cars? TFA talks about using Li-ion packs from electric vehicles after they've worn down in efficiency. (The article gives the example of a 24kwh pack that only has 18kwh of capacity left, after being used for 14 years.) Even when they're worn out, such batteries are hardly "inexpensive" but they might be a good fit for peak-load smoothing in a data center or similar use. Ultimately, they'll have to be recycled, but this might be a way to get a few more years of service out of them.
