The need for negative emissions technologies to address our climate crisis has become increasingly clear. At the rate that our planet is emitting carbon dioxide – adding about 50 gigatons every year – we will have to remove carbon dioxide at the gigaton scale by 2050 in order to achieve “net zero” emissions.
Carbon dioxide dissolves in oceans, lakes and ponds, forming bicarbonate ions that can reenter the atmosphere as carbon dioxide later. Now, researchers have developed tiny “nanojars” that split bicarbonate into carbonate and capture it. They will present their results at ACS Fall 2021.
An Engineering professor, Chulalongkorn University has successfully converted carbon dioxide to methanol via a thermochemical method that consumes less energy and provides more yield, providing an alternative solution to reduce greenhouse gas emissions and stimulate the circular economy.
