Green Hydrogen and Europe’s Energy Transition

Europe’s long-term climate and energy strategy hinges on the rapid deployment of green hydrogen as a clean alternative to fossil fuels. As the European Union sets ambitious net-zero targets for 2050, attention has turned to an unlikely player in the transition—the very fossil fuel refineries historically associated with carbon-heavy operations. A new analysis by Wood Mackenzie highlights that these refineries could hold the key to scaling up green hydrogen production, positioning Europe as a leader in clean energy transformation.

Why Fossil Fuel Refineries Matter

Refineries across Europe already possess much of the physical and operational infrastructure necessary to produce and process hydrogen. Pipelines, storage facilities, and energy-intensive systems are embedded into these facilities, making them well-suited for adaptation to hydrogen production. Instead of building brand-new greenfield hydrogen plants at massive costs, leveraging existing refinery assets offers both economic and logistical advantages.

Wood Mackenzie’s report stresses that these sites also serve as major energy demand centers, where hydrogen can be consumed immediately in industrial processes or distributed via existing networks. This built-in demand reduces the chicken-and-egg problem of scaling hydrogen markets, as production and consumption can happen in tandem at the same sites.

The Role of Green Hydrogen in Net-Zero Ambitions

Hydrogen is seen as a cornerstone of Europe’s energy future. While blue hydrogen—produced from natural gas with carbon capture—plays a transitional role, green hydrogen, generated from renewable electricity through electrolysis, is the ultimate goal. It has the potential to decarbonize hard-to-abate sectors such as steelmaking, aviation, shipping, and chemicals.

Refineries, with their long history of handling hydrogen for fuel desulfurization and chemical refining, are natural first movers. Transitioning them from fossil-based hydrogen (often called grey hydrogen) to green alternatives could cut millions of tons of CO₂ emissions annually, while also accelerating the growth of Europe’s renewable power sector, which will be required to feed electrolysis systems.

Economic Advantages and Industrial Synergy

Building electrolysis plants from scratch requires not only huge investments but also permitting, grid connections, and workforce development. By reusing refinery infrastructure, companies can cut costs, streamline construction timelines, and take advantage of skilled labor already in place.

Wood Mackenzie points out that integrating hydrogen production into refineries also ensures steady demand, which is critical for lowering the price of hydrogen through economies of scale. Once cost competitiveness improves, hydrogen can be expanded into other markets such as mobility, long-haul trucking, and residential heating.

The Refinery-to-Hydrogen Transformation Model

Many European refineries are already taking steps toward this transition. Projects such as Repsol’s hydrogen initiatives in Spain and Shell’s Rheinland refinery in Germany demonstrate how fossil-heavy operations can be repurposed into clean energy hubs. These facilities are adding electrolyzers, renewable power inputs, and CO₂ capture technologies, making them central to the EU’s hydrogen economy roadmap.

This hybrid model—where fossil fuels and hydrogen production co-exist—may prove vital during the transition years. While fossil-based fuels will still be in demand, the gradual increase in hydrogen capacity allows for a smooth handover toward cleaner systems without destabilizing energy markets.

Energy Security and Strategic Value

Beyond climate goals, refineries transitioning into hydrogen hubs bolster Europe’s energy security. With geopolitical tensions and dependence on imported natural gas, especially from Russia, Europe needs alternatives that reduce reliance on external sources. Green hydrogen, produced domestically, offers sovereignty in fuel supply.

Moreover, by transforming refineries, Europe avoids leaving massive industrial assets stranded. Instead of shutting down refineries outright, the region can adapt them for a new purpose, sustaining jobs and maintaining industrial competitiveness.

Challenges

Despite the advantages, scaling green hydrogen through refineries is not without challenges. Electrolyzer technology must advance in efficiency and drop significantly in cost. Renewable energy generation must expand massively to power hydrogen production at scale. There are also policy and regulatory questions about subsidies, hydrogen infrastructure standards, and cross-border energy trade.

Furthermore, public perception remains a challenge. Critics argue that using fossil refineries risks slowing the transition, allowing oil companies to retain dominance while only partially decarbonizing. Policymakers will need to enforce strict guidelines to ensure green hydrogen replaces, rather than supplements, fossil-based operations.

The Global Context

Europe’s approach is being closely watched by other regions. Asia, particularly Japan and South Korea, is betting heavily on hydrogen imports, while the U.S. is deploying hydrogen hubs under the Inflation Reduction Act. Yet, Europe’s refinery-based strategy could give it a unique edge. By combining existing assets with aggressive policy targets, Europe could leapfrog into large-scale hydrogen deployment ahead of competitors.

Wood Mackenzie emphasizes that Europe’s integrated approach—renewable power, existing infrastructure, and industrial demand—forms a complete ecosystem. If executed effectively, it could place the EU at the forefront of global hydrogen leadership, setting standards and exporting expertise.

A Transformative Moment

The call to repurpose fossil refineries is emblematic of the broader shift in Europe’s energy thinking: transformation rather than abandonment. Instead of dismantling the past, Europe is choosing to build on it, turning yesterday’s carbon-heavy assets into tomorrow’s clean energy pillars.

This strategy carries symbolic weight too. Refineries, once symbols of fossil dominance, could become the flagbearers of decarbonization. Such a transition would not only redefine energy landscapes but also reshape Europe’s industrial identity for decades to come.

The Path Forward

Wood Mackenzie’s findings underscore a pivotal truth—Europe cannot reach its hydrogen ambitions without reimagining its existing energy infrastructure. Fossil fuel refineries, often seen as relics of the past, may turn out to be the catalysts of the future.

By converting them into hydrogen hubs, Europe gains a faster, more cost-effective, and more secure path to scaling green hydrogen. This transformation is not merely technical; it is strategic, economic, and political. If policymakers, industry leaders, and investors align, Europe’s refineries could light the way to a cleaner and more resilient energy future.
