2025 Collaborative R&D Lead participant

An integrated hardware and optimised control system for multi-fuel delivery infrastructure for low carbon vessels and shoreside plant

1 Sep 2025 to 31 Mar 2026

Awarded
£216,681
Total cost £309,544

Whilst transitioning to low-carbon shipping, multiple low-carbon fuels are currently being developed. It is likely that different fuels will be used by ships depending on operational requirements, like voyage duration and specific cargo. This poses difficulties for port operators developing onsite infrastructure which can service demands of vessels with d...

NextGen Electrolysis - Producing Green Hydrogen from Contaminated Water

1 Aug 2024 to 31 Jul 2025

Awarded
£188,902
Total cost £269,860

Green hydrogen has the potential to replace large quantities of natural gas demands in "hard to abate" sectors like industrial heat and transport, however it currently faces certain barriers to widespread adoption. One of these is the requirement for highly purified water, with current electrolysers requiring water which has gone through reverse osmosis, ...
