Cambridge clean energy startup Remedium wins £50k Climate Impact Prize

The prize, awarded by NZTC sponsor ConocoPhillips, is given to the startup with the most promising emissions reduction and commercial impact potential.

Remedium’s technology, Limeloop, captures carbon dioxide from industrial processes such as cement and steel production – sectors that are especially difficult to decarbonise. The system uses a custom-made synthetic limestone and a heat battery to trap more CO₂ at a significantly lower cost.

It promises to remove over 90 per cent of emissions while producing high-temperature heat for industry, with the potential to reduce capture costs by more than 80 per cent compared to current methods. It comes as new figures highlight the centre’s role in boosting the economy, supporting innovation and creating jobs across Scotland and the UK.

Omid Saghafifar, Chief Executive of Remedium, said: “Winning the Climate Impact Prize is a real boost for our team. It recognises the progress we’ve made and the potential of our technology to help cut emissions.

“The TechX programme has helped us sharpen our thinking and move faster towards getting our solution into the hands of customers.

“This award comes at the right time for us. The funding will support the next phase of our development, whether that’s building partnerships, testing at scale or refining the technology. “We’re genuinely grateful to NZTC and ConocoPhillips for their backing and belief in what we’re building.”

Held at Aberdeen’s Music Hall, the event marked the conclusion of this year’s 18-week TechX accelerator programme.

Each of the graduating startups pitched their ideas to an audience of industry leaders, investors and tech experts. The event was also livestreamed to viewers worldwide.

This year’s group of 12 startups includes companies focused on greener fuels, digital tools for offshore energy, low-carbon hydrogen and new methods for capturing or cutting carbon emissions.

While Cambridge-based Remedium took the top prize, all participants will receive further support through TechX Growth, a two-year programme offering co-working space, access to NZTC’s network of experts and investors, and its ecosystem partners.
