Response to EU’s next long-term budget (MFF) – EU funding for competitiveness
4 Nov 2025
H2SITE welcomes the European Commissions Communication on the next MFF and its ambition to build a more independent, competitive, and sustainable Europe. We strongly support the vision of an investment-focused budget that aligns financial instruments with strategic priorities such as technological leadership, decarbonisation, industrial resilience, and energy independence. However, for the MFF to deliver tangible impact on innovation, competitiveness, and sustainability, implementation mechanisms must match ambition. Based on our experience, we offer the following comments and recommendations: 1. Strengthening the European Competitiveness Fund: The creation of the ECF is a major step forward. We welcome its intention to bridge research and deployment, streamline programmes, and simplify access to funding. To maximise impact we would recommend ensuring continuity of funding across the innovation chain, from R&D to industrial deployment and manufacturing, avoiding gaps between Horizon Europe, Innovation Fund, and InvestEU instruments. Better efficiency could be done by introducing simplified and faster procedures, reducing administrative burdens that disproportionately affect SMEs and deep-tech startups and establishing common rules and unified portals for all EU competitiveness-related funds, as proposed, to enhance accessibility and transparency. Finally, ensuring evaluation criteria reward innovation potential and impact, not only technological maturity or short-term market readiness would be a very good step, and early-stage technologies with transformative potential, such as hydrogen separation and purification or ammonia cracking technologies, require tailored assessment. 2. Enhancing strategic autonomy and industrial resilience: We support the focus on reducing strategic dependencies, particularly in critical raw materials, clean technology manufacturing, and energy systems. The ECF should promote EU-based manufacturing and supply chains in clean and advanced technologies through targeted support and demand-side instruments (e.g., green procurement, industrial decarbonisation bank). Also, it should encourage cross-border demonstration projects and facilitate collaboration between SMEs, research centres, and large industries to accelerate industrial deployment. Finally, H2SITE strongly believes that the ECF has to support the scale-up of innovative hydrogen and ammonia technologies especially regarding ammonia cracking as a cornerstone of the Clean Industrial Deal and the transition to energy autonomy. 3. Simplification, flexibility, and accessibility: The Communications emphasis on simplification and flexibility is welcome. For this to translate into practice, H2SITE recommends to reduce fragmentation across programmes and funds as the current overlap creates confusion and limits synergies. Moreover, the implementation of results-based funding that measures real-world outcomes (e.g., CO reduction, jobs created, resilience achieved) is better than excessive compliance reporting. 4. Supporting SMEs and emerging innovators: A dynamic MFF must recognise SMEs as drivers of innovation and competitiveness. We recommend to create dedicated SME windows or simplified tracks within the ECF and Horizon Europe as well as funding schemes that de-risk private investment in early-stage deep-tech ventures. Finally, we expect support for publicprivate partnerships and IPCEIs accessible to smaller players, not only large consortia. 5. Aligning with the Green and Digital transitions: The MFFs ambition to allocate at least 35% of expenditure to climate and environmental objectives is essential. However, the EU should integrate climate neutrality, energy efficiency, and circularity as core criteria across all funding streams, not only dedicated green instruments and support digitalisation and data-driven innovation as enablers of industrial efficiency and decarbonisation.

24 Jul 2025
H2SITE welcomes the opportunity to provide feedback on the forthcoming EU Ports Strategy. As a European technology provider specializing in advanced palladium-alloy membrane reactors for hydrogen purification and separation, we are committed to supporting the decarbonization and competitiveness of the maritime sector. We believe the EU Ports Strategy can play a pivotal role in accelerating the adoption of clean fuels and innovative hydrogen technologies across European ports. The maritime sector remains a significant source of CO and NO emissions. Transitioning to hydrogen and its carriers offers a path to near-zero tank-to-wake emissions, either through direct combustion, use in fuel cells, or hydrogen-rich blends. However, hydrogen's transport and storage involve technical and economic challengessuch as high-pressure or cryogenic handlingwhich raise delivery costs and safety concerns. To enable large-scale deployment, the strategy must adopt a comprehensive and integrated approach. This starts with explicitly recognizing ammonia and methanol as strategic hydrogen carriers. Clear recognition will guide investment and regulation, fostering dedicated infrastructure for storage, handling, and bunkering, and enabling their role as viable alternatives to fossil fuels. Equally essential is support for onboard hydrogen generation technologiesspecifically, ammonia and methanol cracking combined with hydrogen purification. These allow vessels to produce high-purity hydrogen on demand, addressing key logistics hurdles and enabling scalable, flexible deployment in both retrofitted and new ships. Aligned with the objectives of AFIR and AFIF, the Strategy should also encourage the deployment of off-grid hydrogen and power systems in ports. These solutions can be deployed more rapidly than major infrastructure upgrades, offering on-demand clean energy and hydrogen without depending on grid reinforcement or variable sources. This facilitates faster decarbonization of port operations and improves energy resilience while reducing CAPEX. A harmonized safety and regulatory framework is critical to ensuring consistent deployment across the EU. Clear standards for handling and converting ammonia and methanol at ports and onboard vessels will mitigate risks, ensure operational safety, and build stakeholder confidence. Infrastructure investment must be prioritized, with EU funding mechanisms supporting ports in adapting facilities to hydrogen carriers and associated technologies. Modernizing port capabilities will position Europe as a leader in clean maritime innovation. Workforce readiness is equally vital. Dedicated training for port staff and seafarers will ensure the safe operation of hydrogen technologies and support long-term sustainability. Finally, sustained support for pilot projects and demonstration activities will be essential to accelerate innovation, validate technologies, and prepare the market for rapid uptake. In summary, the EU Ports Strategy must integrate recognition of hydrogen carriers, support for onboard generation, off-grid systems, regulatory harmonization, infrastructure development, workforce training, and innovation funding into a coherent framework. H2SITE stands ready to collaborate with the European Commission, Member States, and industry stakeholders to help European ports lead the global shift to clean maritime energy.

24 Jul 2025
H2SITE welcomes the European Commissions initiative to develop an EU Industrial Maritime Strategy, and its close alignment with the upcoming EU Port Strategy. As a technology provider specialising in hydrogen purification and membrane-based ammonia cracking, we are an active player in enabling the decarbonisation of maritime transport, in line with EU Green Deal objectives and the FuelEU Maritime Regulation. We would like to highlight the following priorities and recommendations from the perspective of an innovative SME delivering deep-tech solutions for clean ammonia and hydrogen use in ports and onboard ships: 1. Recognise the Role of Enabling Technologies such as Ammonia Cracking and Hydrogen Purification To achieve deep decarbonisation in maritime transport, Europe must support the deployment of ammonia as a hydrogen carrier, not only as a fuel in itself. Technologies like membrane reactors for onboard ammonia cracking and hydrogen purification are vital to: Power PEM fuel cells with high-purity hydrogen (>99.97%) Retrofit ships using hydrogen-ammonia blends Reduce infrastructure pressure by allowing flexible, modular deployment in ports The EU Industrial maritime strategy should explicitly support port-based and onboard hydrogen extraction from ammonia through technology-neutral R&I and infrastructure funding. 2. Prioritise Ammonia Infrastructure in Ports under AFIR & the Port Strategy The current AFIR lacks explicit operational targets for ammonia bunkering. Yet ammonia is the most promising hydrogen carrier for long-range maritime transport. H2SITE calls the EU to include ammonia in port bunkering infrastructure targets (AFIR, AFIF) and support storage retrofits, floating bunkering, and safety certification development. 3. Support SME Innovation and First-of-a-Kind Demonstrations Europes maritime competitiveness relies on homegrown clean-tech innovators, especially SMEs like H2SITE. Demonstration projects such as H2OCEAN and MERCHANT, in which H2SITE deploys onboard ammonia-to-hydrogen systems, show strong potential for replication in EU ports and vessels. We would recommend allocating targeted Innovation Fund, Hydrogen Bank, and CEF Transport support for SME-led projects and modular solutions enabling port decarbonisation. 4. Foster Regulatory Coherence and Certification Alignment (IMO/EU) Ammonia and hydrogen fuels will only scale if EU and IMO frameworks are harmonised. The Commission must streamline certification schemes for alternative fuels, covering: Feedstock origin Carbon intensity Molecule purity The EU Industrial maritime strategy should promote harmonised, digital certification schemes that integrate purity specifications (especially for PEM use) and lifecycle assessments. 5. Enable Short-Sea Shipping and Retrofit Market Development Short-sea and coastal shipping segments offer a rapid decarbonisation opportunity using ammonia-derived hydrogen, especially in retrofit configurations combining diesel-electric systems with PEM fuel cells or hydrogen-ICEs. The EU should include short-sea and retrofit-specific targets in the EU Industrial maritime strategy and allow for soft-loan or CAPEX support for conversion-ready vessels and port-side ammonia cracking units. 6. Ensure Strategic Autonomy by Supporting EU Clean Fuel Technology Providers As global competition intensifies, the EU must avoid new dependencies in the maritime energy transition. It is vital to support the development and manufacturing of clean propulsion components and systems in Europe, including: Membrane reactors Hydrogen purification technologies Ammonia-compatible safety and detection systems This should be reflected in the Industrial Maritime Strategy through the creation of strategic value chains for clean fuel equipment as part of the Clean Industrial Deal. In conclusion, we applaud the EUs commitment to strengthening Europes maritime ecosystem.

Specific Feedback on Key Points: 1. Emissions from Aviation and Maritime Sectors: We support the EU's efforts to encourage a global carbon pricing system through the ICAO and the IMO. H2SITE's technology can play a crucial role in reducing emissions from maritime transport by enabling the use of clean hydrogen as a fuel source. 2. Carbon Leakage: We recognize the importance of addressing carbon leakage, especially for industries exposed to climate policy costs. H2SITE's solutions can help mitigate this risk by providing cost-effective hydrogen purification technologies, which can be integrated into industrial processes to reduce emissions without compromising competitiveness. 3. Carbon Absorption and Utilization: The inclusion of permanent carbon absorption methods, such as bioCSC and DACCS, in the EU ETS is a positive step. H2SITE's technology can complement these efforts by ensuring that hydrogen used in various applications is of high purity, thereby maximizing the efficiency of carbon reduction strategies. 4. Thermal Power Thresholds: We support the evaluation of lowering the thermal power thresholds for inclusion in the ETS. This could encourage smaller emitters to adopt cleaner technologies, including those provided by H2SITE, thereby broadening the impact of emission reduction efforts. 5. Linking with Other Carbon Markets: Establishing links between the EU ETS and other carbon markets can enhance liquidity and reduce the cost of emission reductions. H2SITE's technology can be a valuable asset in such integrated markets, providing a reliable means of reducing emissions across different sectors. 6. Maritime Emissions: We support the Commission's plan to evaluate the carbon pricing mechanisms and market-based measures that could be adopted by the International Maritime Organization (IMO) in 2025. This evaluation should ensure that any new measures complement the EU ETS and avoid double charging for maritime operators. H2SITE's technology can facilitate the transition to cleaner fuels, such as hydrogen, thereby supporting these regulatory efforts. H2SITE strongly believes that the Commission should extend the scope of the ETS to include emissions from smaller vessels, specifically those with a gross tonnage of less than 5,000 but not less than 400. By including smaller ships, the ETS can drive broader adoption of emission-reducing technologies, including those offered by H2SITE. This extension will create a more level playing field and encourage innovation across the maritime sector. The Commission should closely monitor the implementation of the recent extension of the ETS to maritime transport. This includes assessing the impact on essential maritime services, such as those providing territorial continuity to islands and remote regions, including the EU's outermost regions. H2SITE's technology can play a crucial role in ensuring that these services can effectively utilize hydrogen as a clean fuel, supporting both environmental and economic objectives. We advocate for simplifying and improving the ETS to ensure coherence with other EU legislation, particularly regarding the treatment of biomass and the promotion of renewable and low-carbon maritime fuels. H2SITE's membrane reactors can help streamline the adoption of hydrogen-based solutions, aligning with the EU's goals for a cleaner and more efficient maritime sector. Rationalizing the rules for monitoring, reporting, and verification will reduce administrative burdens and encourage wider participation in the ETS, further driving the adoption of clean technologies like ours. 7. Market Stability Reserve: The review of the Market Stability Reserve parameters is essential for maintaining the effectiveness of the ETS. H2SITE's technology can contribute to stabilizing the market by providing a reliable and efficient means of reducing emissions, thereby supporting industrial growth and competitiveness.

16 Apr 2025
H2SITE is an innovative SME active in hydrogen purification and production. As such, H2SITE contributes directly to industrial decarbonisation by enabling access to clean hydrogen where and when it is needed even in hard-to-abate or distributed contexts. 1. Speeding Up Permitting Procedures We strongly support the Commissions objective to simplify and accelerate permitting procedures for decarbonisation technologies. For innovative SMEs like H2SITE, long and complex procedures delay deployment and market access. In particular: Membrane-based hydrogen systems are often misunderstood or not clearly addressed in current permitting frameworks, which are primarily designed around large-scale electrolysers or CCS infrastructure. Standardised guidance at EU level on the deployment of small to mid-scale hydrogen purification systems (including safety and siting rules) would help Member States avoid unnecessary duplication and delays. 2. Recognition of Distributed and Niche Technologies as Priority Projects While the draft Act focuses on large industrial clusters, it is crucial to include distributed decarbonisation technologies as well particularly those enabling flexible hydrogen access in ports, terminals, remote sites or mobile applications. H2SITEs systems: Enable onboard hydrogen use through ammonia cracking and purification on ships, helping decarbonise maritime transport. Can recover and purify natural hydrogen at the point of extraction, opening access to new low-cost, low-carbon hydrogen sources in Europe. Provide grid compatibility monitoring by measuring and ensuring hydrogen blending levels in natural gas do not exceed regulatory limits, ensuring system integrity and consumer safety. Support regional interconnections and decentralised infrastructure, aligning with the resilience goals of the Clean Industrial Deal. Such applications should be considered priority enablers in the EUs decarbonisation strategy and be eligible for support and fast-tracked permitting. 3. Incentives and Funding Mechanisms for Industrial Decarbonisation We encourage the European Commission to prioritise financial mechanisms that reduce investment risk and accelerate deployment of low-carbon technologies. In particular: Dedicated EU funding windows under the Innovation Fund or Horizon Europe for SMEs that supply enabling decarbonisation technologies, such as hydrogen purification or modular processing units. Contracts for Difference (CfDs) or Carbon Contracts for industrial decarbonisation, helping industries bridge the cost gap between conventional and low-carbon solutions. Tax credits, CAPEX subsidies or operational aid for early deployment of hydrogen-related technologies including purification and distribution should be made available to both technology suppliers and adopters. Blending public-private finance to de-risk deployment through EIB instruments and innovation procurement tools. Importantly, EU instruments should not only support flagship mega-projects, but also ensure accessibility for high-impact SMEs and mid-scale technologies that are ready for market but face significant scale-up barriers. 4. Creating and Protecting European Lead Markets H2SITE welcomes the proposed support for European low-carbon products and clean technologies. However, we stress the need to: Ensure that SMEs can access lead markets and benefit from EU procurement and innovation support. Promote flexible hydrogen technologies that can adapt to existing industrial setups and energy infrastructures. Avoid a one-size-fits-all approach when defining clean industrial technology purification, separation, and distributed H2 production are as critical as generation technologies. We support the development of a voluntary EU label for low-carbon products, and urge the Commission to also consider certification pathways for hydrogen purity and distributed usage efficiency, not only carbon intensity.

25 Mar 2025
H2SITE welcomes the Strategic Technologies for Europe Platform (STEP) as a timely and strategic initiative to reinforce Europes leadership in critical clean technologies. As a European technology provider, we specialize in hydrogen purification and separation through palladium alloy membrane reactors a technology essential to enabling renewable and low-carbon hydrogen deployment at scale. While STEP rightly focuses on clean tech manufacturing, it is crucial to ensure that hydrogen conditioning technologies purification, separation, and hydrogen recovery are fully integrated into its scope. These are vital enablers for the hydrogen economy and Europes energy sovereignty. Purification and Separation: The Hidden Backbone of the Hydrogen Economy Policy and investment efforts often concentrate on hydrogen production (electrolysers) or storage. Yet, hydrogen conditioning the ability to purify hydrogen to required standards, separate it from other gases, or recover it from carriers or blends is equally strategic. Without advanced purification and separation capabilities, Europe risks bottlenecks in: - Meeting high-purity hydrogen demands for industry, mobility, and energy; - Unlocking the value of imported hydrogen carriers (ammonia, methanol, LOHCs) at ports and industrial hubs; - Enabling the sustainable use of natural hydrogen resources; - Managing hydrogen-natural gas blends in grids, ensuring compliance with safety and regulatory limits; Facilitating cross-border or regional interconnections, where gas quality and hydrogen content must be controlled. H2SITE: A European Solution with Broad Applications Our membrane reactors enable among others: - Ammonia cracking and hydrogen purification both at import terminals and onboard ships, providing clean fuel directly to vessels; - Purification of natural hydrogen at the source, enabling its valorization; - Real-time separation of hydrogen blended into natural gas grids, preventing regulatory caps from being exceeded; - Gas quality control at interconnection points, supporting cross-border energy flows. - Water gas shift - Hydrogen recovery from industrial processes - Production of hydrogen from biogas/biomass These applications are essential to: - Operationalize hydrogen imports and trade; - Secure high-purity hydrogen for sensitive uses (fuel cells, industry); - Optimize hydrogen infrastructure investments across Europe; - Decarbonisation of Industrial processes. We strongly encourage the STEP Platform to: 1. Recognize hydrogen purification, separation, and conditioning technologies as strategic clean tech areas; 2. Include port infrastructure, onboard systems, and grid-level applications within its eligible projects; 3. Support the deployment of European solutions that maximize the efficiency and flexibility of the hydrogen supply chain; 4. Ensure strategic autonomy in technologies critical to hydrogen valorization, beyond production. H2SITE stands ready to contribute to Europes clean energy transition by unlocking hydrogen where it is in carriers, blends, or natural formations and delivering it where it is needed at the right purity. We believe STEP has a unique opportunity to position Europe as a leader not only in hydrogen production but also in the technologies that make hydrogen usable, tradeable, and scalable. We welcome further engagement with the European Commission and STEP stakeholders to elaborate on these points.
