A London-based start-up is shrinking the size of carbon capture plants as it tries to popularise a green technology that’s been slow to expand beyond limited applications.

Carbon Clean Solutions is building small, replicable reactors that can remove carbon dioxide from industry and power generators. Carbon capture could be a key way for companies to eliminate their emissions quickly, as governments issue net-zero mandates before the COP26 climate summit in Glasgow, Scotland.

Techniques have been around for years, but the low price of pollution dimmed their appeal. In Europe, it costs about €60 (R1,000) to release a metric ton of carbon dioxide into the atmosphere for industries covered by the bloc’s emissions market.
