Public Funding for Greenjets Limited

This 6-month feasibility study, a collaboration between Greenjets Ltd and the world leading Whittle Laboratory, University of Cambridge, aims to develop a scalable AI-driven design for customised e-propulsion engines in the transport sector, specifically for Advanced Aerial Mobility solutions, i.e. drones. Customised drones offer optimised performance for various last-mile delivery use cases, reducing energy consumption and emissions compared to other vehicles. Greenjets, as an early-revenue UK SME, faces challenges in the slow and expensive design process, hindering market penetration. To capitalise on the growing AAM market, Greenjets must achieve optimal bespoke designs within shorter timeframes. The Whittle Laboratory, University of Cambridge has developed a novel methodology combining rapid testing and physical parameterisation to address this. Successful implementation of this methodology will enable AI-driven decision making, reducing design time and allowing Greenjets to scale production to meet diverse customer requirements efficiently.

ZEHPHyr1, Zero Emission Hydrogen Powered Hovercraft, is an 8-month feasibility which will de-risk the key barriers to zero-emission hovercraft operations. These barriers include -- operational barriers (socio-economics, crew training, regulations, life cycle impact), technical barriers (hydrogen-based propulsion system) and availability of hydrogen infrastructure (production, storage, distribution, bunkering, integration with wider infrastructure/mobility). The central innovation in the project is the replacement of the diesel engines in today's hovercraft with a zero-emission hydrogen propulsion system consisting of MW class fuel cells, electric thrusters and high-power batteries. The project's goal is to find credible solutions to overcoming the above barriers and in doing so, pave the way for follow-on phases of development, where the novel propulsion system will be demonstrated on 12-seat and 80-seat hovercraft. Introduction of zero-emission hovercraft into commercial service is expected in 2027/28, with letters of support received from potential end users. In addition to the hovercraft, additional spillover products are expected to be commercialised as a result of the project, namely MW class fuel cells and batteries (into other marine vessels) and electric thrusters (into other industries, e.g., aerospace). The project team consists of a best-of-breed consortium well placed to deliver the desired goals of the project. Led by Blue Bear, the team includes, Griffon Hoverwork Limited, Bramble Energy, Nyobolt, Aquatera and the European Marine Energy Centre (EMEC).

Project InCEPTion will develop a novel all-electric propulsion module that is safe-by-design, scalable, modular, power dense, quiet, efficient and enables the combined use of batteries and fuel cells in aircraft. The module will accelerate the electrification of various classes of electric aircraft (0-30 PAX), from eVTOLs, general aviation eCTOLs, up to sub-regional aircraft. The best-of-breed UK consortium includes - Greenjets (Lead, previously Blue Bear), Drive System Design, Ricardo, Dowty Propellers, M&I Materials, University of Cambridge-Whittle Laboratory, University of Salford-Salford Acoustics. The propulsion module will incorporate and demonstrate key innovations, including rotor and stator aerofoils and structures optimized aerodynamically for enhanced electric efficiency and reduced noise. It will also feature a battery power and control system with advanced thermal management, utilizing dielectric fluid for improved performance, and a rim-driven dual-stage motor for higher power density and operational reliability.
