Studies of the development of clean hydrogen have often focused on the production side. Infrastructure built and used for storage and transportation warrants more attention. Among the topics that should be assessed are system design, operation, integration, and ownership; market design and...

As renewable hydrogen becomes central to decarbonizing hard-to-abate sectors, such as steel manufacturing or heavy transport, deployment in Emerging Markets and Developing Countries depends on obtaining timely environmental and social permits on the social acceptance of hydrogen production...

Achieving a net-zero energy system in Europe by 2050 will likely require large-scale deployment of hydrogen and seasonal energy storage to manage variability in renewable supply and demand. This study addresses two key objectives: (1) to develop a modeling framework that integrates seasonal...

Electric, hydrogen, methanol, and biofuel cars are becoming popular for reducing road transport emissions. In limited operational contexts, these technologies are commonly called clean or zero-emission, but resource availability, lifetime implications, and infrastructural restrictions determine...

Transforming EU-funded research into real-world solutions: H2SITE brings membrane reactor and separator technology to market; Scaling up innovation: an incubator for Europe's electrolyser industry; On the road to zero emissions: advancing MEA performance for fuel cell vehicles; Bringing hydrogen...

he energy transition is not only topical in an European context, but has important ramification for the Global South. In his master’s thesis, Jakob Rammer addresses this global dimension and provides a nuanced analysis of energy projects in Chile supported by European actors. Using the example...

Drop-in alternative liquid fuels—Renewable Diesel (RD) and Sustainable Aviation Fuel (SAF)—offer material near-term abatement for hard-to-electrify transport segments, such as Aviation and heavy-duty transport; their deployment depends on pathway-specific costs, hydrogen requirements, and...

The study provides a technical analysis as support for further standardization activities on the gas quality in Europe's future hydrogen infrastructure. It synthesizes key literature on the influence of different supply chain elements on hydrogen gas composition and assesses the implications of...

This study critically examines HYBRIT (Hydrogen Breakthrough Ironmaking Technology), a Swedish flagship project-led by the government-owned iron ore company LKAB-to produce fossil-free sponge iron using hydrogen from fossil-free electricity. Positioned as a cornerstone of the EU Green Deal and...

Clean hydrogen is a nascent technology that could play an essential role to achieve net-zero emissions. However, less than 10% of announced clean hydrogen projects worldwide have reached final investment decision, as equity and debt investors often consider these projects to be too risky. This...

Hydrogen produced from renewable energy sources or with carbon capture and storage is an important pillar for reducing global emissions. Using structured interviews, we collect and analyze expectations of 47 industry, science, and government experts on hydrogen pathways and policy needs in...

The EU CBAM is the EU's landmark tool to put a fair price on the carbon emitted during the production of certain carbon-intensive goods, including hydrogen, entering the EU. It will ensure that the EU's climate objectives are not undermined and encourage cleaner industrial production in non-EU...

Many countries of the Global South struggle to achieve inclusive growth paths despite investment in the exploitation of rich resources. Resource-based industrialization literature stresses the potential for achieving broader development effects via the development of production linkages with...

Green hydrogen, a zero-carbon emission fuel, has become a real competitor to transform the energy market, thanks to improvements in the electrolysis process, decreased costs, and the presence of renewable energy resources. Energy industries have shown considerable progress in hydrogen production...

The year 2024 saw a year of important developments for the Clean Hydrogen JU, continuing built on the achievements of previous years and intensifying the efforts on hydrogen valleys. With a total operational commitment of EUR 203 million, and the launch of 22 new projects, the overall portfolio...

This report supports the European Commission (DG ENER) in the design and implementation of a European import auction for renewable hydrogen and its derivatives under the European Hydrogen Bank (EHB). The EHB aims to contribute to the EU's climate neutrality goal by 2050. While domestic auctions...

Este informe analiza y destaca la oportunidad de Colombia para posicionarse como un actor clave a nivel global en el suministro de combustibles basados en hidrógeno verde para el transporte marítimo y otros sectores. El análisis evaluó la incipiente economía del hidrógeno verde en Colombia...

Whereas hydrogen is currently a marginal energy carrier, the aim of the EU is to trigger low-carbon hydrogen production that covers around 10 percent of EU’s energy needs by 2050. If this comes true, it will be an energy revolution. We study competition between green and blue hydrogen by...

Global efforts to keep the rise in average temperatures within 1.5 degree Celsius are falling short. To achieve this goal, more extensive decarbonization measures are necessary across all sectors of the economy. Clean hydrogen is hydrogen that is produced using methods that result in limited or...

Combined cycle (CC) plants are expected to play an important role in balancing generation of heat and electricity from non-dispatchable renewable energy sources. In this work, we study different retrofit options for using hydrogen in CC plants to reduce the plant's CO2 emissions. These options...

The economies of fossil fuel exporters are threatened by global efforts to transition away from using unabated fossil fuels. Producing clean hydrogen, for export or domestic use in manufacturing, provides a potentially major opportunity to continue exploiting their fossil fuel resources....

As decarbonisation efforts accelerate globally, the role of large-scale underground storage for energy and climate-related gases – natural gas, hydrogen, and carbon dioxide – is becoming increasingly important. While the demand for natural gas as a transition fuel is expected to rise at...

The European Commission highlights hydrogen as an important energy carrier and chemical feedstock that could help decarbonise sectors otherwise deemed hard-to-abate. Europe's existing natural gas grid is seen as a promising asset to repurpose for the transportation of hydrogen. This technical...
