1Position paper on including hydrogen carrier technologies in existing and future public funding schemes
Integrating hydrogen carrier technologies into existing and future public funding schemes is paramount for advancing
the global transition to a clean energy landscape. This position paper advocates for the deliberate inclusion ofhydrogen carrier technologies in funding schemes designed to support scale-up projects, emphasizing the need forcomprehensive and forward-thinking approaches.
Context
The Fit-for-55 framework and associated measures are paving the way towards a clean hydrogen economy for which
imports are needed. The transportation and storage of hydrogen plays an essential role in achieving these targets
Hydrogen Carriers offer sustainable and safe solutions to transport and store hydrogen. Carrier technologies must playa significant role in achieving the EU's decarbonisation goals by connecting supply and demand centres, bothintercontinental and intra-EU.
Defining Hydrogen Carrier Technologies
Hydrogen Carriers include:• Liquid Organic Hydrogen Carrier (LOHC), e.g., Toluene or Benzyltoluene• Liquid Inorganic Hydrogen Carrier (LIHC), e.g., silica-based• Solid Hydrogen Carrier (SHC), e.g., potassium borohydride/KBH4
Hydrogen Carriers can utilise (existing) conventional (liquid fuel) infrastructure for large-scale transportation andstorage of hydrogen. These carriers serve primarily to store and deliver hydrogen and are not used as an energy
product on their own like hydrogen derivatives (e.g., NH3, MeOH). The hazard potential is similar to, or, in some cases,
less than that of most conventional liquid fossil fuels or petroleum-based products 1. Clear advantage of carrier
technologies is the safe and efficient storage and transportation of hydrogen along with its flexibility, due to thefungibility with existing infrastructure and safety practices it offers. As the hydrogen is no longer handled in its
molecular form, the hazard potential significantly decreases. Due to their properties, these carrier technologies arehandled under ambient conditions regardless of their hydrogen load. Some of these carriers, such as Liquid Organic
Hydrogen Carriers (LOHCs) already have a high technology readiness level (TRL 7 or higher as defined by the IEA), of
the full value chain including hydrogen conversion and reconversion.2
Technology neutral scale-up funding
Recent acknowledgement of amongst other the German Hydrogen strategy that a significant amount of hydrogen willneed to be imported into the European Union reinforces that programmes like H2Global or the expected internationalleg of the European Hydrogen Bank should also focus on the import of molecular hydrogen, allowing the tenderapplicants to choose the most economical transport technology for their individual supply chain. Tender designs, that
only include Hydrogen Derivatives (e.g., NH3, MeOH) as eligible product, lead to the exclusion of the above-mentionedhydrogen carrier technologies, especially of LOHCs, inadvertently impacting technology competitiveness and theEuropean Union’s ability to reach its targets. Fallback options for the delivery of Hydrogen Derivatives instead ofhydrogen would delay the facilitation of hydrogen imports and related infrastructure. Therefore, H2Global tenders
and the European Hydrogen Bank import leg should prioritise tenders for delivering hydrogen to the offtaker or for
direct grid injection. This allows for competition among different hydrogen transport technologies and should bereflected in upcoming tender terms and conditions.
By pursuing a technology-neutral stance, funding initiatives can effectively foster innovation and competition whileallowing broader chances to timely import and deliver molecular hydrogen to European offtakers. The signatories callfor international collaboration in establishing robust supply chains for molecular hydrogen, recognizing that a global
effort is essential for the successful deployment of maritime hydrogen import supply chains. Highlighting the readinessof hydrogen carriers to deliver molecular hydrogen, strategic investments will not only accelerate technologicaladvancements but also contribute to the broader goal of achieving a sustainable and decarbonized future are needed.
