Minerals From Waste, Carbon From the Ocean

The world urgently needs critical minerals like nickel and rare earth elements to power the energy transition, but traditional mining is environmentally destructive and geopolitically fraught. BlueShift, based in Cambridge, Massachusetts, is tackling both problems at once with a membrane-free electrochemical technology that extracts critical minerals from alkaline industrial waste and seawater — while simultaneously removing CO2 from the ocean as limestone.

Co-founded by Deep Patel and David Kwabi, the technology was developed through research at the University of Michigan and Harvard, with support from ARPA-E. BlueShift raised a $2.1M pre-seed round backed by ConocoPhillips and is currently running a pilot at Boston Harbor through the Greentown Labs and MIT The Engine accelerator programs.

A Two-Revenue-Stream Approach

BlueShift's process is 10 times more energy efficient and 7 times cheaper than competing mineral extraction methods. What makes the business model particularly compelling is its dual revenue stream: the company can sell extracted critical minerals while also generating carbon removal credits from the CO2 sequestered as limestone. With Patel's engineering background from Amazon Lab126 and UMich, and Kwabi's electrochemistry expertise from MIT and Yale, the founders bring both the technical depth and commercialization experience needed to bring this science out of the lab.
