Industries such as cement, steel and petrochemicals emit 8 billion tonnes of CO₂ annually, with carbon capture being the most viable reduction method. However, current global capacity is just 43 Mt, far below the 2,000 Mt required by 2040, and high costs of $70–$195 per tonne hinder adoption. Calcium looping, which uses cheap limestone, offers promise but is limited by sorbent degradation and high energy costs.

Remedium’s ‘Limeloop’ solution, developed after five years of R&D, addresses these challenges by using a synthetic limestone with a unique stabiliser dispersion. This innovation reduces material costs by over 80% and allows Limeloop to capture 36 times more CO₂ over its lifetime.

The carbon capture heat battery further cuts energy costs by operating in dual modes. Mode 1 captures over 90% of CO₂ while providing high-temperature heat for industrial processes, and Mode 2 regenerates sorbents using low-cost, intermittent electricity. This reduces capture costs to just $13/tCO₂, more than 80% lower than current methods.
