Trees naturally pull CO₂ from the air as they grow, storing carbon in their wood. By managing forests sustainably, we can use wood and forestry residues to create products and generate energy, reducing our reliance on fossil fuels.

At bioenergy facilities, sustainably sourced biomass—such as forestry residues—is used to produce heat and power. During combustion, biogenic CO₂ is released, but instead of entering the atmosphere, it’s captured from the plant’s flue gases using proven technology. This process shifts the system from carbon-neutral to carbon-negative.

Once captured, the CO₂ gas is cooled and compressed to make it compact and stable, essential for safe and efficient transportation. In this liquid-like state, it can be stored in tanks until it’s ready to be moved.

The liquified CO₂ is then shipped to its permanent storage location by pipeline, train, or specialized vessel under stringent safety measures that ensure secure handling at every step.

Upon arrival at the storage site, the CO₂ is injected deep underground into geological reservoirs called deep saline aquifers—often located beneath the North Sea. These reservoirs lie beneath a thick, impermeable rock layer that prevents the CO₂ from migrating upwards.

Within the aquifer, the CO₂ is trapped in tiny pore spaces, dissolves into the salty water, and over time forms solid minerals. This natural barrier of rock, combined with these processes, keeps the CO₂ securely locked away for more than a thousand years.
