CCU is a broad term that covers processes that aim at capturing CO2 from flue gas or directly from the air and converting it into a variety of products such as renewable fuels, chemicals, and materials. CO2 has already been used for decades with mature technologies in various industrial processes to produce e.g. beverages, fertilisers, etc. But today, numerous new CCU technologies at various stages of development and commercialisation aim at mitigating climate change. These technologies have the potential to
- reduce net CO2 emissions,
- remove CO2 from the air,
- provide substitutes for carbon-intensive and fossil-based products,
- store and transport renewable energy,
- generate marketable products.
