EU Eco has substantial commercial expertise in developing and delivering thermoelectric generators for the renewable energy market.  Recently together they successfully delivered a seed R&D grant for the UK Space Agency, demonstrating the viability and performance of its thermoelectric generator technology for the space sector, as well as a NATEP demonstration project proving the technical viability of thermoelectrics for hybrid power aircraft.

The team is composed of the following partners: (1) EU ECO, a micro SME and inventor of the Prometheus thermoelectric module/generator (2) Arrow Energy Ltd -  a SME who are the UK’s integration design engineers and hold the UK distribution rights. (3) IWS – InnovationWorks Systems Ltd, a micro SME supporting development and delivery of high tech aerospace technology and projects (4) Cranfield University a world leader in aerospace technology and UK academic leader in aircraft electrification (and participant in the ATI funded Fresson electrification project) (5) Blackburn College, leading college in the UK Midlands and supporter of the Prometheus TEG (6) BAE, No cost participant and end user for the project providing end user requirements for aerospace applications.

The mix of the team is unique and has a 360-degree view of the topic of the commercial, industrial and aerospace electrification and system development including academia, SMEs in a leading role and large primes as the end user.  Arrow Energy have extensive integration design experience across a broad range of commercial and industrial sectors.  The team has been collaborating for the past 4 years with Cranfield University on Prometheus and has an excellent track record of delivering research results, design work and commercial power units on time/budget.  The project will rely on the experience of its key personnel and specifically:




  • 1kW/kg power density, 24-7 with a 150 deg C temperature differential

  • No moving parts

  • Manufacturing and value chain are all UK based (Blackburn)

  • Use of novel 3D/ink printing manufacturing techniques enables use of more semiconductors per square cm (double) compared to competition.

  • Mass and low cost manufacturing process being proved

  • Zero carbon emissions and a 100% green technology

  • Short ROI per application (3-5 years)

  • Heat recovery method

  • Modular power modules in kW, MW blocks

  • Proof of concept technology validated in UK Space Agency and Aerospace Technology Institute R&D grants completed in 2019

  • Significant R&D grants from UK funding councils (UK Space Agency and Aerospace Technology Institute, Innovate UK) and private investors (total of ~1M£)
