Clean energy start-ups receive up to £100k each to develop innovative technologies

Case Studies

12 clean energy start-ups have been awarded up to £100k each by the Net Zero Technology Centre (NZTC) to help develop innovative technologies that will assist with the UK’s energy transition. 

In addition to the funding each start-up will also receive access to NZTC’s network of mentors and investors, as part of the Centre’s TechX Clean Energy Accelerator, now in its sixth year. 

Following 15 weeks of investor readiness training, refining business models, business storytelling and more, the programme will feature a Demo Day in June 2024, where the companies will have the opportunity to showcase their solutions to industry and investors, with potential to win further funding.

The winning start-ups are:

  • Airspection: Drones designed for more reliable, more robust and safer offshore infrastructure inspection
  • Apleum: Technology to convert renewable energy, carbon dioxide and water into zero carbon jet fuel
  • Kali Technology: Carbon-zero industrial process heating using low cost, integrated heat pump technology
  • Frontier Robotics: Platform-agnostic software and associated hardware for autonomous underwater inspections
  • HyWaves: Power management control system to increase hydrogen production for dedicated solar-to-hydrogen, and lowering cost
  • H2CHP: Fuel-flexible power generator targeted at ports offering full control over the combustion process to operate at high efficiency with zero carbon emissions
  • INERGIO Technologies: Novel system design that combines advantages of fuel cells and diesel generators for sustainable off-grid and backup power solutions
  • MECHAPRES: High-temperature heat pump with embedded thermal storage for industrial heat decarbonisation, with heat and steam as a service potential
  • Modjoule: Smart, battery-equipped containers for cost-effective electrification of shipping vessels
  • Reaforma: Leveraging construction waste for secure carbon capture and storage in a novel carbon-negative composite
  • Soltropy: Novel solar thermal technology for buildings that harvests carbon neutral heat all year round
  • SurreyH2: Lower cost green hydrogen production technology using a recirculating catalyst, with intrinsic hydrogen storage capability

To date, 57 clean energy start-ups have been supported through the programme, collectively generating £32M in revenue, creating 443 new jobs, and achieving 7 commercialisations already achieved. These companies are forecast to enable 20-25 million tonnes of greenhouse gas emissions savings per year by 2030.

Chief Acceleration Officer & TechX Director Mark Anderson, said:

“As NZTC welcomes its sixth TechX cohort, we reiterate the pivotal role entrepreneurs will play in accelerating the energy transition.

“This year’s cohort introduces compelling innovations, offering solutions to propel the adoption of clean and affordable energy. TechX start-ups are the companies of the future, poised to reshape the energy landscape and help lead us towards net zero.”

UK Government Minister for Scotland Malcolm Offord, said:

“Congratulations to those selected for the TechX Clean Energy Accelerator programme. Start-up companies play a fundamental role in driving innovation in the energy sector, supporting sustainable economic growth, and delivering solutions to the environmental issues we all face today.

“The UK Government is investing £90 million in the Net Zero Technology Centre and more than £2.9 billion to level up right across Scotland.”
