As our TechX programmes continues to go from strength to strength, so do our alumni, with 45 technology start-ups successfully completing the accelerator programme.

The alumni have completed over 20 field trials and six have commercialised (Intebloc, Nudge Exchange, Optic Earth, Resolute Energy Solutions, Sentinel Subsea and Test1). Find out how the TechX Accelerator programme and its growth programme have helped scale them to shape the future of clean energy technology. 

Mocean Energy

A start-up from the second cohort in 2019, Mocean Energy has secured more than £5.5 million in public funding for its wave energy technology. In November 2020 the Edinburgh start-up raised £612,000 equity seed funding and £250,000 from Innovate UK to advance the design of its Blue Star wave machine and drive its adoption in subsea oil and gas.

Mocean is currently in a £1.6M project with the Net Zero Technology Centre, Harbour Energy, EC-OG and Modus to demonstrate the potential of its Blue X wave energy prototype to power a subsea battery and a remote underwater vehicle.

"When we joined the TechX Accelerator programme, Mocean was small, and the energy transition was just beginning. With support from the Net Zero Technology Centre, government, and industry, we are now making an impact.

"TechX push you out of the nest - meeting potential customers and meeting potential partners. It’s taken me out of my comfort zone, out the door, meeting and talking to people a lot more!"

Cameron McNatt, Managing Director of Mocean Energy


A start-up from the third cohort in 2020, Carnot has raised £370,000 in pre-seed funding and won a £300,000 Eureka Eurostars grant in December 2020.

Co-founded in 2019, Carnot is developing game-changing power units with twice the efficiency, half the fuel consumption and potentially zero CO2 emissions compared to current engines.

"You’re either part of the problem or part of the solution - the Net Zero Technology Centre are certainly the latter. They are doing a great job in bringing all the solutions together in one big roundtable.

"As a cleantech start-up operating in energy generation/storage, we definitely benefited from the TechX Accelerator - working with the talent and expertise offered through the TechX programme and the partners/mentors associated with it."

Archie Watts-Farmer, Chief Executive Officer of Carnot


A start-up from the third cohort, Supercritical has radically redesigned the electrolyser to deliver low cost, pressurised, zero-emission hydrogen.

In May 2021 the company completed a three month BEIS-funded feasibility study for its green hydrogen based decarbonisation technology at Beam Suntory’s Ardmore distillery. In June they were awarded a £320,000 Smart Grant by InnovateUK to help develop and test their fully operational multi-cell electrolyser module, which is capable of operating above the critical point of water and delivers high pressure hydrogen without any hydrogen gas compressors.

"Through the TechX Accelerator programme, we have made some amazing progress forging relationships with industry who are clearly looking for decarbonisation solutions."

Luke Tan, Chief Product Officer of Supercritical
