Projects
REducing Greenhouse Gases from Ammonia Engines (REGGAE)
1 Sep 2025 to 31 Mar 2026
**REGGAE** will deliver innovative and cost-effective catalytic technologies for the simultaneous reduction of N2O greenhouse gases, toxic NH3 and NOx emissions from NH3-fuelled engines. This will be achieved through innovative de-N2O catalytic and Ammonia-Slip-Catalyst (ASC) formulations and an aftertreatment systems design. In a collaboration between JM...
REACT: Retrofittable Emission-Free Ammonia Combustion Technology
1 Sep 2025 to 31 Mar 2026
The project will involve pre-deployment trials of a mono-fuelled ammonia engine generator set, developed as a retrofit solution for current diesel engines. The work builds upon recent feasibility research under the EPSRC "_MariNH3_" programme and CMDC4 "_ENTICE_" project, which has proven experimentally in state-of-the-art ammonia engine laboratories how ...
Backup generator for Ports Utilities and Ships
1 Sep 2025 to 31 Mar 2026
Hydrogen and hydrogen energy vectors (e.g. NH3) are alternatives to accelerate the sustainable decarbonisation of power generation and transport sectors, while reducing overall energy demand as well as social and environmental impacts. There are hundreds of thousands of generators within ports and ships which are operated on fossil fuels (e.g. diesel). Th...
SMARTY: Sustainable Methacrylate Advanced Research Technology for Yeast
1 Sep 2025 to 28 Feb 2027
Project lead, Ingenza Ltd. will apply cutting edge engineering biology to advance the commercial utility of a non-conventional yeast with properties very suited to industrial use (e.g. rapid growth, feedstock versatility, high product tolerance) but severely lacking to date in the methods and genetic tools necessary for effective biotechnology application...
Greater Manchester Electro-Chemical Hydrogen Cluster (GMEHC) phase2
1 Apr 2025 to 31 Mar 2026
The **Greater Manchester Electro-Chemical Hydrogen Cluster (GMEHC) phase 2 project** builds on GMEHC phase 1's aim to create an ecosystem to facilitate accelerated innovation and an investible business case. It will bring together areas of regional expertise to support innovation, enhance Greater Manchester's and the UK's capability in electrochemical hyd...
APOLO
1 Jan 2024 to 31 Dec 2027
Through a holistic approach, APOLO aims to tackle the challenges of power conversion from ammonia and develop an efficient and flexible ammonia cracking technology. This technology will be coupled with fuel cells and engines to achieve complete decarbonization of the maritime sector. As the main objective of the call is to demonstrate scalability beyond 3...
AEROSOLS
1 Jan 2024 to 31 Dec 2026
Considering the growing transport demand and dependence on oil, collective and immediate actions must be taken to abate emissions and mitigate their environmental and health impacts. Very fine particles emissions, and the formation of secondary aerosols through atmospheric processing, are believed to be the pollutant with the greatest public health impact...
Quantum Computing based density functionals for fast and accurate materials and chemistry simulations
1 Nov 2023 to 31 Mar 2025
Quantum computers have the potential to lead to a transformative increase in the available computational power. The size and quality of the quantum computers available today are increasing rapidly, and advancements in ability to implement quantum error correction are getting us closer to have quantum computers which will be able to outperform even the bes...
Feasibility of catalyst simulation on near-term quantum hardware
1 Sep 2023 to 28 Feb 2025
Quantum computers are expected to be able to solve hard computational challenges that are beyond the reach of our best standard supercomputers. After many years of research in both academia and industry, quantum computers are at the point of outperforming their standard ("classical") counterparts in certain specialised problems. One of the most exciting a...
