Remedium was named winner of the Climate Impact Prize at the Net Zero Technology Centre’s annual TechX Demo Day in Aberdeen. The prize, awarded by NZTC sponsor ConocoPhillips, is given to the startup with the most promising emissions reduction and commercial impact potential.
It comes as new figures highlight the centre’s role in boosting the economy, supporting innovation and creating jobs across Scotland and the UK. Held at Aberdeen’s Music Hall on Thursday, 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.
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.
The TechX programme accelerates the development of clean energy solutions, providing a clear pathway to field trials, commercial partnerships and adoption.
By harnessing TechX’s resources, NZTC aims to reduce the time it takes for these innovations to reach the market, and increase the likelihood.
Since its launch in 2017, TechX has supported 81 startups through its accelerator, with more than 1,300 companies applying to take part.
Companies supported by TechX – including its 2025 cohort – have created 380 jobs, attracted £160 million of equity investment and generated £36 million in revenue, with over 90 per cent still thriving. Overall, NZTC has co-invested £420 million and delivered 1,550 jobs through its technology development and deployment projects.
