An article on combating the catastrophic impacts of global warming through carbon emissions reduction and carbon dioxide removal strategies. The technologies for reducing emissions are mature, but removal strategies require support. Only 45% of CO2 emissions remain in the atmosphere, with the rest absorbed by the oceans and biological cycle. Ocean acidification due to CO2 dissolution threatens marine species and ecosystems.
Researchers are exploring solutions like ocean alkalinity enhancement (OAE) to rebalance ocean pH and absorb atmospheric CO2. Electrochemical approaches like bipolar membrane electrodialysis show promise in combating ocean acidification. Economic incentives and rising climate change awareness are driving the development of carbon dioxide reduction technologies like BMED.
Challenges include membrane limitations and operational costs, but efforts are underway to develop cost-effective OAE solutions. Start-ups like Ebb Carbon, SeaO2, and Vesta are focusing on ocean carbon dioxide removal through OAE. Collaboration between stakeholders is essential to address challenges and validate large-scale OAE implementation globally. Support and funding are crucial for scaling these technologies and combatting climate change effectively.
