Bioenergy with Carbon Capture and Utilization (BECCU)
Producing energy from biomass and capturing the CO₂ for utilization.
What is Bioenergy with Carbon Capture and Utilization (BECCU)?
Bioenergy with Carbon Capture and Utilization (BECCU) involves generating energy (electricity, heat, or biofuels) from biomass, capturing the CO₂ produced during this process, and then using that captured CO₂ as a feedstock for various products or processes. Unlike BECCS, where CO₂ is stored, in BECCU it is re-used.
Why is Bioenergy with Carbon Capture and Utilization (BECCU) important?
BECCU is important because it combines renewable energy production with carbon management, potentially creating value from captured CO₂ while reducing reliance on fossil fuels. If the utilization results in durable storage (e.g., in building materials), it can contribute to carbon removal.

Frequently asked questions
The key difference is what happens to the captured CO₂: in BECCS, it's permanently stored (e.g., underground), while in BECCU, it's utilized as a resource for other products or processes.
BECCU can be a carbon removal method if the CO₂ utilization leads to durable, long-term storage of the carbon, effectively preventing its return to the atmosphere (e.g., in concrete). If the CO₂ is used for short-lived products or released quickly, it's not considered carbon removal.
Applications include producing synthetic fuels, chemicals, plastics, building materials (e.g., concrete), or enhancing photosynthesis in greenhouses.
