Hydrogen Grant Funding in the UK: Complete Guide

The UK has committed to becoming a global leader in hydrogen. With the UK Hydrogen Strategy targeting 10GW of low-carbon hydrogen production capacity by 2030, billions of pounds in public and private funding are flowing into hydrogen production, storage, distribution, and end-use technologies. This guide maps every major grant funding route available to UK hydrogen companies, from the Net Zero Hydrogen Fund through to Horizon Europe, and explains how to position your technology for maximum success.

The UK Hydrogen Strategy and Why Funding Is Available

Hydrogen is central to the UK's net zero strategy. The government's 2021 UK Hydrogen Strategy, updated by the 2023 Hydrogen Strategy Update, positions hydrogen as essential for decarbonising sectors that electricity alone cannot reach: heavy industry, long-distance transport, shipping, aviation, and high-temperature heat. The updated ambition of 10GW by 2030, up from the original 5GW target, signals a doubling of government commitment to the sector.

This political commitment translates directly into funding. The government has allocated over £1 billion specifically for hydrogen across DESNZ (Department for Energy Security and Net Zero), UKRI, and Innovate UK programmes. On top of that, hydrogen technologies are eligible for a range of broader clean energy and industrial decarbonisation funds that are not hydrogen-specific but where hydrogen projects compete strongly.

For climate tech SMEs and mid-stage companies developing hydrogen technologies, this landscape represents a significant opportunity but also a challenge. The number of overlapping programmes, differing eligibility criteria, and varying timelines can make it difficult to know where to focus. This guide breaks down each major funding source, explains who it is for, and provides practical advice on how to approach it.

Net Zero Hydrogen Fund (NZHF)

The Net Zero Hydrogen Fund is the UK government's flagship hydrogen funding programme, administered by DESNZ. With up to £240 million in capital funding, the NZHF supports the commercial deployment of low-carbon hydrogen production projects across the UK. It is the single most important funding programme for companies building hydrogen production capacity at scale.

The NZHF operates across multiple strands, each targeting a different stage of project development:

Strand 1: FEED Studies

Front-End Engineering Design studies for projects that have completed initial feasibility. Grants typically cover up to 50% of FEED costs, with awards ranging from £100,000 to several million pounds depending on project scale. Applicants must demonstrate a credible route to deployment and a realistic timeline for reaching final investment decision (FID).

Strand 2: Capital Co-Investment

Devex and capex co-funding for hydrogen production projects approaching deployment. This strand provides the largest awards in the NZHF, with grants of up to £30 million or more for significant production facilities. Successful applicants need to demonstrate offtake arrangements, planning progress, and private sector co-investment commitment.

Eligibility and Key Criteria

The NZHF targets low-carbon hydrogen production specifically, covering both electrolytic (green) and CCUS-enabled (blue) hydrogen. Projects must be based in the UK and demonstrate a clear emissions reduction pathway. Assessors evaluate technical maturity, commercial viability, scalability, deliverability, and value for public money. Companies with technologies at TRL 6-9 are the primary target, though earlier-stage production innovations may qualify for Strand 1 FEED funding.

Innovate UK Hydrogen-Specific Calls

Innovate UK, the UK's innovation agency and part of UKRI, runs several funding programmes that are directly relevant to hydrogen companies. Unlike the NZHF, which focuses on production deployment, Innovate UK programmes tend to support earlier-stage research, development, and demonstration across the entire hydrogen value chain: production, storage, distribution, and end-use applications.

Smart Grants

Innovate UK Smart Grants are the most accessible entry point for hydrogen innovators. These are always-open, sector-agnostic competitions that fund disruptive R&D with strong commercial potential. Hydrogen technologies compete against innovations from all sectors, so your application must clearly articulate what is genuinely novel about your approach. Single-company projects can apply for £100,000 to £500,000, while collaborative projects involving multiple partners can access up to £2 million. Success rates typically sit between 10-15%, making a strong application essential. The key differentiator for successful hydrogen bids is demonstrating a clear improvement over the current state of the art, whether that is electrolyser efficiency, novel catalyst materials, cost reduction in balance of plant, or innovative storage solutions.

ISCF and Strategic Challenges

The Industrial Strategy Challenge Fund (ISCF) and its successors have run several hydrogen-specific calls. Past challenges have included the Hydrogen Supply Competition, the Industrial Fuel Switching programme, and various calls under the Transforming Foundation Industries challenge. While these tend to be time-limited, new strategic challenges with hydrogen relevance are announced regularly. Grants range from £250,000 for feasibility studies to £10 million or more for large collaborative demonstration projects. These calls typically require consortia with industry, academic, and sometimes public-sector partners.

CR&D and Collaborative R&D

UKRI Collaborative R&D competitions fund multi-partner projects that address specific technical challenges. Hydrogen technologies frequently feature in energy, transport, and manufacturing-focused calls. These projects typically last 18-36 months with total budgets between £1 million and £10 million. Academic partners often provide complementary capabilities in materials science, catalysis, systems modelling, or techno-economic analysis that strengthen the bid.

To stay ahead of upcoming hydrogen-relevant calls, consider running a GrantMatch Scan to map all live and anticipated funding opportunities to your specific technology and stage.

ATI Programme: Hydrogen in Aviation

The Aerospace Technology Institute (ATI) Programme is a joint government-industry initiative that provides grant funding for aerospace R&D in the UK. Hydrogen is now one of the ATI's highest-priority technology areas, reflecting the aviation industry's recognition that hydrogen, whether as a direct combustion fuel or as a feedstock for sustainable aviation fuel (SAF), is critical to meeting net zero aviation targets.

The ATI Programme has funded several landmark hydrogen-aviation projects, including liquid hydrogen fuel system development, hydrogen propulsion architectures, and hydrogen-powered aircraft subsystems. Projects range from fundamental research (TRL 2-3) through to full-scale demonstrators (TRL 6-7). Grant sizes vary considerably: smaller feasibility studies may receive £500,000 to £2 million, while major demonstrators and platform-level projects can attract £10 million to £50 million in public funding.

Eligibility for the ATI Programme requires that the technology has a clear application in civil aerospace. However, the definition is broad enough to include hydrogen production for SAF, cryogenic storage systems, fuel cells for auxiliary power units, and ground-side hydrogen infrastructure for airports. If your hydrogen technology has an aviation pathway, the ATI Programme should be a primary target. Applications require a strong industrial partner, typically a Tier 1 aerospace company or airframer, as part of the consortium.

Hydrogen BECCS and Industrial Decarbonisation Funds

Hydrogen plays a central role in the UK's industrial decarbonisation strategy. Several funding programmes target the intersection of hydrogen and heavy industry, including steelmaking, chemicals, cement, glass, and ceramics. These programmes recognise that many industrial processes require high-temperature heat that cannot be easily electrified, making hydrogen a critical decarbonisation pathway.

The Industrial Energy Transformation Fund (IETF), administered by DESNZ, provides capital grants to help energy-intensive businesses switch to low-carbon fuels, including hydrogen. Phase 3 of the IETF has allocated over £185 million in grant funding for industrial decarbonisation projects. Hydrogen fuel-switching projects are particularly well-suited to this programme, especially where they can demonstrate replicability across multiple industrial sites.

Hydrogen BECCS (Bioenergy with Carbon Capture and Storage) represents a specific funding opportunity at the intersection of hydrogen production and negative emissions. The concept involves producing hydrogen from biomass while capturing and storing the resulting CO2, delivering both clean hydrogen and negative emissions. DESNZ and UKRI have funded feasibility studies and pilot projects in this area, and further funding is expected as the UK refines its greenhouse gas removal strategy. For companies working on gasification, pyrolysis, or reforming technologies that can process biogenic feedstocks, Hydrogen BECCS represents a strategically valuable funding angle.

The Industrial Decarbonisation Challenge, part of UKRI's wider challenge portfolio, has funded large-scale hydrogen deployment projects in industrial clusters. These projects typically involve multiple industrial partners, hydrogen producers, infrastructure operators, and research organisations working together to demonstrate hydrogen at cluster scale. Individual partner grants within these large consortia can reach £5 million to £15 million.

Regional Hydrogen Cluster Funding

The UK's hydrogen strategy has a strong regional dimension. The government has identified several industrial clusters as priority areas for hydrogen deployment, including Humber, Teesside, HyNet (North West), South Wales, Grangemouth (Scotland), and the Southampton-Solent corridor. Each of these regions has its own hydrogen ecosystem, funding mechanisms, and strategic priorities.

Regional hydrogen funding takes several forms. Devolved administrations, particularly the Scottish Government and the Welsh Government, operate their own hydrogen-specific funding programmes. The Scottish Government's Hydrogen Action Plan is backed by dedicated funding for hydrogen production, distribution, and end-use demonstration projects. Scottish Enterprise and Highlands and Islands Enterprise also offer R&D grants that hydrogen companies can access.

English regions benefit from the UK Shared Prosperity Fund, Town Deals, and Levelling Up Fund, all of which can support hydrogen infrastructure projects. Combined authorities and local enterprise partnerships (LEPs) in hydrogen cluster regions often provide additional match funding or letters of support that strengthen national-level bids. Being embedded in a recognised hydrogen cluster can significantly strengthen your application to the NZHF or Innovate UK calls, because assessors value projects that contribute to established cluster development plans and have clear routes to offtake.

For companies that are not already located in a hydrogen cluster, the strategic question is whether to partner with cluster-based organisations or to target non-cluster funding routes. Both approaches can work, but the cluster pathway offers advantages in terms of shared infrastructure, regulatory support, and a pre-existing ecosystem of potential customers and partners.

Horizon Europe Hydrogen Opportunities

With the UK's association to Horizon Europe confirmed, UK hydrogen companies now have full access to the largest research and innovation funding programme in the world. Horizon Europe allocates approximately EUR 95.5 billion across 2021-2027, and hydrogen features prominently in Cluster 5 (Climate, Energy and Mobility) of Pillar II.

The Clean Hydrogen Joint Undertaking (Clean Hydrogen JU) is the most important Horizon Europe vehicle for hydrogen companies. It is a public-private partnership between the European Commission, Hydrogen Europe (the industry association), and Hydrogen Europe Research (the research association). The Clean Hydrogen JU publishes annual work programmes with specific call topics covering the entire hydrogen value chain, from advanced electrolysis and novel production methods through to hydrogen storage, transport, distribution, and applications in transport, industry, and the built environment.

Typical Clean Hydrogen JU grants range from EUR 2 million to EUR 5 million per partner within consortia of 5-15 organisations from at least three different countries. The funding rate for research and innovation actions (RIA) is 100% of eligible costs, while innovation actions (IA) are funded at 70% for commercial partners and 100% for research organisations. UK companies can lead these consortia, which is a significant advantage in shaping the project scope and direction.

Beyond the Clean Hydrogen JU, standard Horizon Europe calls under Cluster 5 regularly include topics relevant to hydrogen companies, such as integrated energy systems, sector coupling, and energy storage. The EIC Accelerator also funds breakthrough hydrogen technologies through its blended finance instrument (up to EUR 2.5 million grant plus up to EUR 15 million equity investment). Building a European consortium requires time and relationships. Our Consortium Leadership service helps UK hydrogen companies identify the right partners and structure competitive bids.

How to Position Your Hydrogen Technology for Maximum Success

Winning hydrogen grant funding requires more than a strong technology. Assessors evaluate applications against specific criteria, and understanding what they prioritise is the difference between a funded project and a rejection. Based on our experience supporting hydrogen bids across every major UK programme, here are the factors that separate winning applications from the rest.

Quantify the Innovation Gap

Every hydrogen bid must clearly articulate what exists today, why it is insufficient, and precisely what your innovation changes. Generic claims about “improved efficiency” are not enough. Assessors want specific, quantified comparisons: current electrolyser stacks operate at X kWh/kg, your technology targets Y kWh/kg, and this matters because it reduces production cost by Z%. Benchmark your technology against the state of the art using published literature, competitor specifications, and industry roadmaps.

Demonstrate Market Pull

The hydrogen economy is still nascent, which means assessors are particularly focused on whether real customers will buy your product. Letters of support from potential offtakers, Memoranda of Understanding with industrial end-users, and evidence of commercial conversations all strengthen your bid. If you are developing production technology, show who will buy the hydrogen and at what price. If you are developing end-use technology, show the total addressable market and why customers will switch from incumbent solutions.

Build a Credible Consortium

For collaborative bids, your consortium composition tells assessors whether the project can actually deliver. Include partners that cover the full value chain: technology developers, component suppliers, systems integrators, end-users, and academic partners for underpinning research. Avoid consortia where every partner is doing the same thing. Assessors want complementary capabilities with minimal overlap. Each partner should have a clear, justified role with defined deliverables.

Align with Policy Priorities

Hydrogen funding is inherently political. Your application should explicitly connect to the UK Hydrogen Strategy, the Ten Point Plan for a Green Industrial Revolution, the Net Zero Strategy, and, where relevant, regional hydrogen cluster plans. Show how your project contributes to the government's 10GW target and how it creates UK jobs, builds UK supply chain capability, and supports export potential. Assessors working within DESNZ and UKRI are evaluated on how their portfolio delivers against these policy objectives.

Get the Financials Right

Hydrogen projects often involve significant capital expenditure, which means your financial case needs to be robust. Include detailed cost breakdowns, realistic co-funding plans, and a credible path to commercial viability without ongoing subsidy. For production projects, your levelised cost of hydrogen (LCOH) analysis should be transparent and benchmarked against DESNZ and industry projections. Assessors will challenge unrealistic cost assumptions. It is better to be conservative and credible than optimistic and questionable.

GreenFundr's Hydrogen Sector Experience

Hydrogen is one of GreenFundr's deepest sectors. Our founder and team have supported hydrogen bids across the full spectrum of UK and European programmes, from early-stage Innovate UK feasibility studies through to multi-million-pound NZHF production projects and Horizon Europe collaborative research.

Our track record includes work on projects such as LH-SIFT (Liquid Hydrogen for Sustainable Intermodal Freight Transport), a cross-sector initiative developing liquid hydrogen supply chains for heavy-duty transport applications. We have also supported Hydrogen Highways projects focused on building hydrogen refuelling infrastructure corridors and distribution networks. These projects require deep technical understanding of hydrogen systems, from electrolysis and liquefaction through to storage, distribution, and dispensing, combined with the grant-writing expertise needed to present complex technical programmes in the format that assessors expect.

What sets our hydrogen support apart is that we understand both the technology and the funding landscape. We know which programmes are coming, which have historically funded hydrogen projects, and what assessors in each programme prioritise. This means we can advise not just on how to write a strong bid, but on when to bid, which programme to target, and how to structure your consortium for maximum competitiveness.

Frequently Asked Questions

What is the largest hydrogen grant available in the UK?

The Net Zero Hydrogen Fund (NZHF) is the single largest dedicated hydrogen funding programme in the UK, with up to £240 million allocated across multiple rounds. Individual awards under the NZHF can reach tens of millions of pounds for large-scale production projects, particularly those at FEED (Front-End Engineering Design) stage or beyond. For smaller companies and earlier-stage technologies, Innovate UK Smart Grants and ISCF-style challenges typically offer between £100,000 and £2 million per project.

Can startups apply for hydrogen grant funding in the UK?

Yes. Several funding streams are specifically designed for early-stage hydrogen companies. Innovate UK Smart Grants are open to innovative businesses of any size, and many UKRI calls actively encourage SME participation. The key requirement is demonstrating a genuinely novel technology or approach, not company size. Startups should be realistic about which programmes match their technology readiness level: TRL 3-5 technologies suit Innovate UK feasibility studies, while later-stage demonstrations require the NZHF or sector-specific deployment funds.

Do I need a consortium to apply for hydrogen grants?

It depends on the programme. Innovate UK Smart Grants can be submitted by a single company, though collaborative applications often score higher because they demonstrate a credible route to deployment. Horizon Europe and most ISCF-style challenges require multi-partner consortia, typically with at least one academic partner and cross-sector industry representation. The NZHF can accept single-company applications for production projects, but feasibility and FEED studies often involve engineering consultancies and offtakers as partners.

What Technology Readiness Level (TRL) do I need for hydrogen funding?

Different programmes target different TRL bands. Innovate UK feasibility studies typically require TRL 2-4 at the start of the project. Industrial research and Smart Grant projects usually target TRL 4-6. The NZHF primarily funds TRL 6-9 projects that are moving toward deployment and commercial operation. Horizon Europe Pillar II calls span TRL 3-7 depending on the specific topic. Matching your current TRL to the right programme is critical. Applying at the wrong stage is one of the most common reasons hydrogen bids fail.

How long does it take to receive hydrogen grant funding?

From submission to grant offer, most Innovate UK programmes take 3-5 months. Horizon Europe projects typically take 6-9 months from call deadline to grant agreement signature. The NZHF process varies by strand but generally takes 4-8 months including due diligence. You should plan for a further 4-6 weeks for contracting before funds are released. This means you need to start preparing your bid at least 6-8 weeks before the submission deadline, or earlier for consortium bids that require partner alignment and letters of support.

Can UK hydrogen companies still access Horizon Europe funding after Brexit?

Yes. The UK formally associated to Horizon Europe in January 2024, meaning UK-based organisations can participate in and lead Horizon Europe projects on the same terms as EU member state organisations. This is particularly valuable for hydrogen companies because many Horizon Europe Clean Hydrogen Joint Undertaking calls offer grants of EUR 2-5 million per partner. UK companies can also access the EIC Accelerator, which provides up to EUR 2.5 million in grant funding plus optional equity investment for breakthrough technologies.
