Project Innovation + Advantages:
Developed by the University of California, Los Angeles (UCLA), the AMENDER project presents a transformative approach for CDR that exploits the ocean-atmosphere equilibrium of CO2 and enormous abundance of divalent alkaline cations in seawater. These attributes are leveraged electrochemically by flowing seawater through mechanically regenerable electrode surfaces. The minerals formed trap CO2 durably in dissolved and/or solid forms. The decarbonated seawater is then capable of absorbing more atmospheric CO2. Water’s alkalization also generates hydrogen (H2), a clean fuel. UCLA’s AMENDER system could enable a levelized cost of removal of <$100 per tonne of CO2 mineralized.
