Biokull - en konkret karbonlagringshistorie

Biochar Carbon Removal

Biochar is the result of a unique interaction between natural processes and technology: plants and trees are responsible for carbon capture, while technology is responsible for stabilization. Through pyrolysis, we can stabilize the carbon and store it in the ground for hundreds of years when burying it. Each kilogram of biochar from our supplier is equivalent to removing 3.01 kg of CO2 from the cycle.

Biochar is a unique climate technology in a number of areas

1) Measurable negative emissions: 1kg biochar = -3.1 kg CO2e

2) Long-term carbon storage: 75% of the carbon remains unchanged for over 1,000 years, while 25% decomposes after 100 years. (Figures from Permanence of soil-applied biochar, Schmidt et al, 2022)

3) Certified and verified: Recognized by the IPCC and SBTi as Negative Emissions Technology (NET) as necessary to reach the climate goals. The storage comes with climate credit from

4) Only mature NET ready for scaling. Biochar is available now!

5) Biochar production is an energy-positive process. The excess heat goes to nearby industry.

Norsk Karbonlagring's model makes even more of biochar's potential available

6) Inert (does not react with air or soil) = flexible. The carbon can be stored in agricultural land across the country, or in other places our partners want.

7) The carbon comes in handy: Biochar improves soil structure, slows down the effect of fertiliser, increases microbiological life and contributes to climate adaptation (more robustness against a lot of water and drought).

8) Additionally: Our partners enter the start of the carbon storage process. We do not give you credit for an already completed project - we let you take ownership of the entire process, with the credit as a receipt.

9) We require that all raw material/biomass be residual wood/waste/bioresidue

The sum of this allows us to write a credible, verifiable and local climate history together with our partners.
