The Low Carbon Hydrogen Supply 2 (HYS2) competition is the follow on from the highly successful Low Carbon Hydrogen Supply (HS1) [1] competition and aims to accelerate the development of a wide range of innovative low-carbon hydrogen supply solutions to enable development of a hydrogen economy compatible with net zero targets.

The Low Carbon Hydrogen Supply 2 competition is split into two streams: Stream 1 and Stream 2. HYS2 Stream 1 will be for market entry solutions at Technology Readiness Levels (TRLs) 4-6 and HYS2 Stream 2 will be for more mature solutions/technologies at TRLs 6/7 (HS1 was a single stream competition open to TRL 4-7 technologies). Stream 1 and Stream 2 are independent competitions in legal terms, and each has its own separate pre-commercial procurement process.

Stream 1 aims to identify, support and then develop credible innovative hydrogen supply or enabling technologies to bring about a step change in their development.

Stream 1 is expected to run over two phases as outlined below.

This Contracts Finder Notice is for Stream 1 Phase 1 only.

Stream 1: Phase 1 - Feasibility (up to £6m)

The purpose of the feasibility study is to develop the hydrogen supply technology or enabling technology concept. The feasibility study will support the development of the project team's understanding of the core and ancillary technology, the performance of the technology, the market potential, the route to market (including competition) and costs and delivery plan for Phase 2. There will be a total budget of £6m for Phase 1 with minimum £50k and maximum £300k for each feasibility study. Funding will be split between four categories.

Category 1 - Low Carbon Hydrogen Production
Category 2 - Zero Carbon Hydrogen Production
Category 3 - Hydrogen Storage and Transport
Category 4 - Net Zero Hydrogen Supply Solutions

Stream 1: Phase 2 - Demonstration (up to £24m)

This phase will support the physical demonstration of the hydrogen supply solution, including engineering design, build, trial, decommissioning, market assessment, and knowledge dissemination. The demonstration study should either demonstrate the entire hydrogen supply solution (where necessary simulating scenarios of the hydrogen uses), or key components or a prototype in a relevant environment, or further develop and demonstrate the physical design of new solutions to enable low carbon hydrogen supply solutions. Companies will also develop technical and business plans for market deployment.

Applicants for Phase 2 must be successful for Phase 1 and have completed their feasibility study to be eligible for Phase 2. This will have the same Categories as Phase 1 with up to £6m allocated to each Category, providing a total budget of £24m for Phase 2. The maximum funding available per project in Phase 2 is £6m.

Projects for Phase 2 must be completed by 1 February 2025.
