Such small-scale energy systems can operate on or off the larger electricity grid, providing electricity for businesses or communities. That power flows to Crusoe, a cryptocurrency miner that pivoted into developing AI data centers, which has built a facility with 2,000 graphics processing units adjacent to the lot of repurposed EV batteries. (That’s tiny as modern data centers go: Crusoe is developing a $500 billion AI data center for OpenAI and others in Abilene, Texas, where it expects to install 100,000 GPUs across its first two facilities by the end of the year, according to Forbes.) Redwood’s project underscores a growing interest in powering data centers partially or entirely outside the electric grid. But the company stresses they’re an ideal fit for addressing the growing energy needs and climate emissions of data centers.
