Controlling the global warming temperature rise to 2°C or even 1.5°C is crucial for addressing climate change. Artificially removing carbon dioxide from the atmosphere is key to achieving net-zero CO2 plans. Carbon capture and storage (CCS) plays an important role in reducing emissions associated with fossil fuel use.Direct air capture (DAC), which extracts CO2 from … Read more
