About
BlueShift is a Cambridge, Massachusetts startup founded in 2024 developing a membrane-free redox-based electrochemical system that extracts critical minerals and rare earth elements from industrial waste (mine tailings, coal fly ash) while simultaneously mineralizing CO2 from seawater into carbonates. The company exited stealth in March 2025 with $2.1M pre-seed funding from ConocoPhillips, Ridgeline, and MassCEC, and is building a pilot facility at Boston Harbor with a one-ton-per-year nickel/REE target by Q2 2026.
