Reducing the content of carbon dioxide in air is the key to addressing climate change. Carbon capture and storage is an important measure to reduce carbon dioxide emission. Capturing carbon from ambient air directly needs large amounts of energy. The loads on carbon capture devices are flexible, which to some extent can be driven by intermittent energy. Renewable energy such as wind power and solar energy has great potential for development, which has the characteristics of fluctuation. Using renewable energy to capture carbon from ambient air ...
