Ocean-based carbon dioxide removal technology is ramping up, with startups and existing companies racing to develop electrochemical techniques that either remove carbon from seawater or prompt oceans to suck up more. Electrochemical marine carbon dioxide removal (mCDR) aims to store carbon in the ocean or strip it from seawater using electricity. Broadly speaking, mCDR is … Continue reading Electrochemical removal of ocean CO2 offers potential — and concerns
