Projects
London South Bank University and Hydrostar Europe Limited KTP 25_26 R2
1 Mar 2026 to 28 Feb 2029
To develop an integrated hydrogen purification, compression, and storage system using advanced metal hydride technology, enabling cost-effective production of high-purity, high-pressure hydrogen for fuel cell applications in heavy goods vehicles and clean transport, supporting HydroStar's expansion into the rapidly growing green hydrogen market.
HyDigest: A Novel Pathway for Regenerative Organic Fertiliser and Optimised Biomethane Production
1 Jan 2026 to 31 Dec 2028
UK farmers are experiencing pressure to decarbonise farming operations, with the NFU targeting Net-Zero emissions for agriculture by 2040\. The use of synthetic fertiliser is a core source of agricultural emissions, with high manufacturing emissions from natural gas feedstocks, but also through the fast releasing properties of fertiliser resulting in conv...
Demonstrating an innovative hybrid hydrogen and electric powertrain with a novel metal hydride based thermal management system for NRMM.
1 Sep 2025 to 31 Aug 2026
A consortium consisting of leading academia-(LSBU), technology developers-(HydroStar), and industrial first-movers-(KKB), will deliver this ARMD4 project. The consortium will build/showcase a hybrid powertrain utilising both hydrogen and electric technology. The core innovation is a novel thermal management system that utilises waste heat from the battery...
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
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...

1 Oct 2024 to 30 Sep 2028
no public description
An optimised control system for dual-fuel delivery infrastructure for low carbon vessels.
1 Oct 2024 to 28 Feb 2025
In the transition 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, such as voyage duration and specific cargo. This poses difficulties for port operators developing onsite infrastructure which can service the demands of vessels wi...
NextGen Electrolysis - Producing Green Hydrogen from Contaminated Water
1 Aug 2024 to 31 Jul 2025
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, ...
Producing Renewable Hydrogen from Unpurified Water using Floating Photovoltaic Powered Direct Electrolysis
1 Jun 2024 to 28 Feb 2026
HydroStar is a dynamic and innovative company developing Next Generation electrolyser systems which can use impure water as feedstock and remove rare/expensive materials from the design entirely. HydroStar also develops safe and efficient metal hydride hydrogen storage systems which have no leakage and can be used for the compression of hydrogen without t...
An innovative hybrid infrastructure system delivering both electric and hydrogen for vessel fast charging/refuelling using off grid renewable energy and onsite wastewater.
1 Apr 2024 to 31 Mar 2025
In the transition to low carbon shipping, multiple low carbon fuels are currently being investigated. It is likely that in the future different fuel types will be used by ships depending on their operational requirements, such as voyage duration or cargo being carried. This poses a difficulty for port operators in the development of infrastructure which c...
