Refining is the industrial activity that transforms crude oil into the liquid fuels and chemical raw materials on which mobility, industry, and many everyday products depend. According to data from FuelsEurope, it moves 97% of air, sea and land transport in the European Union, covers 100% of military mobility and contributes about 50% of the raw materials used by the continental chemical industry. In Europe, however, refining capacity has fallen by around 20% since 2009 with the closure of 35 refineries. Spain is the exception: it maintains eight operational refineries, has strengthened its capacity in the last two decades and produces about 80% of the kerosene it consumes.
The diesel from the truck that carries the fruit to the supermarket, the kerosene from the plane of a vacation flight or the bitumen that shapes the asphalt of the road come from the same place: a refinery. It is an industrial infrastructure of enormous complexity that makes it possible for energy to reach homes, industries and essential services safely and continuously.
But what role does refining really play in the productive and social fabric and what would happen if Europe stopped considering it a strategic asset for its security and its economy?
Refining is much more than fuel: what it produces and for whom

Refining is a strategic activity with applications that span far beyond mobility, from industry to everyday products.
According to data from the sectoral report prepared by FuelsEurope, refining transforms crude oil into the liquid fuels that move 97% of air, sea and land transport in the European Union, in addition to covering 100% of military and defense mobility needs.
However, its industrial weight does not end in transport. Refineries supply about 50% of the chemical raw materials that feed the manufacturing industry.

Countless products are derived from its processes: bitumen for roads, lubricants for automotive and industry, components for adhesives, coatings, paints, etc. for the manufacture of fertilizers for agriculture, cables, pipes, insulators for industry, etc.
The following table summarizes the main applications of refining by-products:
| Category | Refining by-products |
| Fuels | Gasoline, diesel, kerosene, fuel oil, LPG (butane and propane). Marine fuel, military fuel, renewable fuels. |
| Infrastructure | Road asphalt bitumen, pavement additives. |
| Chemical industry | About 50% of the raw materials: naphtha, aromatics, olefins, plastic bases and synthetic fibers. |
| Manufacturing | Lubricants, waxes, solvents, insulators, cable and pipe additives. |
| Agriculture | Fertilizers, agrochemical formulations and phytosanitary products. |
It is a transformation activity that constitutes the main pillar of the industry, allowing the continuity of continental value chains. However, during the last decades part of this industrial capacity has been losing relative weight within the European context.
A pillar that Europe has been weakening: 35 refineries closed since 2009
A pillar that Europe has been weakening: 35 refineries closed since 2009
Over the past fifteen years, refining capacity on the European continent has experienced a steady decline. Since 2009, 35 refineries have been permanently closed on European soil, which represents the loss of approximately 20% of the total processing capacity, in a context marked by growing international competition, higher energy and operating costs and the need to undertake significant investments to adapt these facilities to new regulatory and technological requirements.
Since 2009, 35 refineries in Europe have been lost, increasing vulnerability and dependence on foreign imports
This withdrawal of industrial assets has not been accompanied by an equivalent drop in demand for refined products. Reducing our capacity may increase European exposure to imports of certain refined products and to disruptions in international markets.
This vulnerability is not new. Europe already had a structural deficit of diesel and kerosene, with a high dependence on imports to cover part of its demand.
Geopolitical events in recent years have highlighted this situation: first, the war in Ukraine forced Europe to reconfigure supply flows; more recently, tensions in the Middle East and disruptions in strategic routes such as the Strait of Hormuz have once again highlighted the risks associated with relying on external markets and logistics corridors for the supply of essential products.
All this raises an inescapable question. What are the risks of this situation?
What is at stake if Europe does not recognize the value of refining
What is at stake if Europe does not recognize the value of refining
Dispensing with domestic refining capacity entails systemic consequences that threaten the economic stability of the continent. Sector analysis identifies clear risks: increased dependence on energy imports, permanent exposure to price volatility in global markets, and loss of highly skilled jobs.
In Europe, the refining industry directly and indirectly supports more than 76,000 workers, contributes 1.8% to the EU GDP and generates more than €31 billion in indirect commercial activity. Added to this is the fact that neglecting this industrial base makes the energy transition process itself more expensive and slows it down.
When a facility is completely dismantled, recovering that industrial capacity requires rebuilding and making substantial investments. On the other hand, keeping industrial assets operational or susceptible to conversion facilitates their adaptation to new technologies and energy uses, taking advantage of existing infrastructures, technical knowledge and capabilities.
Building new facilities from scratch often requires high investments and longer lead times than adapting certain existing assets, although the difference depends on each project and technology. Without refining, Europe not only loses security of supply in the present, but also industrial capacities, skilled employment and part of the associated productive activity, which tends to move to other regions.
Unlike the current of closures experienced in much of Europe, Spain decided to follow a different course and strengthen its industrial network.
The Spanish exception: 8 refineries and reinforced capacity
The Spanish exception: 8 refineries and reinforced capacity
Spain represents a positive exception and an example of long-term strategic vision in comparison to the loss of capacity in the rest of the continent. In the last two decades, while Europe reduced its refining capacity by 20%, in our country we have increased capacity by around 15%, consolidating a highly competitive industrial network made up of eight operating refineries.
In the last two decades, while Europe reduced its refining capacity by 20%, Spain has a significant refining capacity that represents approximately 13% of the European total
This differentiated position is the direct result of sustained investment. Over the last decade, Repsol has allocated an average of approximately €1 billion per year to its five industrial complexes in Spain, including maintenance, modernization, efficiency and production adaptation.
This sustained investment allows us to operate facilities of high technical complexity, capable of processing more than 100 different types of crude oil mainly from the Atlantic basin (United States, Mexico, Brazil) and North Africa, avoiding the exclusive dependence on vulnerable international routes. This operational flexibility has been decisive during the recent international crises. According to data reported by the Government in April 2026, Spain produced around 80% of the kerosene it consumes, a capacity that contributes to strengthening security of supply and responding more quickly to possible disruptions in international markets.
The regional and national economic impact of this network is undeniable: the refining system contributes significantly to the creation of value, industrial employment and the competitiveness of numerous production chains in Spain.
But the strength of these facilities lies not only in securing the current supply, but in their ability to evolve towards the new energy model.

Converting an existing refinery into a multi-energy center makes it possible to take advantage of existing infrastructures to boost the production of fuels and hydrogen from renewable sources. According to sector estimates, taking advantage of already installed infrastructures, logistics and technical knowledge allows capital investment costs to be reduced by between 30% and 50% compared to building greenfield plants from scratch.
Cartagena, Tarragona and Puertollano: Repsol’s operational examples
An industrial transformation that is already an operational reality in our industrial complexes. In Cartagena, Repsol launched the first large-scale 100% renewable fuels plant in the Iberian Peninsula in 2024, with the capacity to produce 250,000 metric tons of 100% renewable diesel and sustainable aviation fuel (SAF) per year. In Tarragona, the company reached a technological milestone by producing 100% renewable gasoline on an industrial scale for the first time. And in Puertollano, it has transformed a conventional refining unit to manufacture 200,000 metric tons of renewable diesel per year, one of the first reconversions of this type carried out in the Iberian Peninsula.
| Complex | Project | Capacity | Milestone |
| Cartagena | 100% renewable fuel plant (diesel of 100% renewable origin + SAF) | 250,000 t/year | First large-scale plant in the Iberian Peninsula (2024) |
| Tarragona | Production of 100% renewable gasoline | Industrial scale | First technological milestone of its kind in Europe |
| Puertollano | Reconversion of conventional refining unit to 100% renewable diesel | 200,000 t/year | One of the first reconversions of this type on the peninsula |
However, for this industrial investment effort to be maintained and deployed on a larger scale, the sector requires a key prerequisite.
What refining needs to remain strategic
What refining needs to remain strategic
To consolidate this industrial transformation and avoid the closure of new plants in Europe, it is essential to have a predictable regulatory framework that acts as a real enabler of investment and not as a bureaucratic or fiscal brake.
The refining sector urges the correction of the cost differences that currently reduce the competitiveness of European plants compared to facilities in third countries. European Union refineries face regulatory costs that their competitors outside Europe cannot bear, which promotes the entry of imported products and can end up displacing industrial activity and emissions outside our borders. An example is the high cost of CO2 associated with the European emission allowance market (EU ETS).
Therefore, I consider it necessary to move towards a framework based on technological neutrality, which allows us to compete under more balanced conditions and make progress in reducing CO2 emissions.
The sector proposes applying a technological-neutral approach that values the different solutions based on their ability to reduce GHG emissions, their viability and their contribution to each mode of transport. The energy transition must be based on the complementarity of all viable solutions, ensuring a level playing field between renewable electricity and renewable fuels in all means of transport.
This approach can promote a more flexible transition, in which electrification and renewable fuels play complementary roles according to the characteristics of each use.
An essential asset

Recognizing the fundamental value of refineries in due time allows us to have accessible, safe and continuous energy while we advance in the development of new technologies that allow us to reduce our carbon footprint.
Europe is at a strategic crossroads: supporting the transformation of its industrial and energy base or accepting a growing foreign dependence that will undermine its autonomy and decision-making capacity. Safeguarding our European refining capacities, modernizing them and providing them with a fair regulatory framework is the best guarantee to ensure the resilience and progress of our continental economy. This debate is framed in the same logic as energy autonomy and security of energy supply, pillars of the new European energy model.
Frequently asked questions about the refining industry in Spain and Europe
Spain has 8 operating refineries, which places it among the European countries with the highest refining capacity. Overall, this network represents approximately 13% of total European capacity, after increasing it by around 15% in the last two decades, in contrast to the 20% reduction recorded in the rest of the continent.
Because it transforms the raw material, producing the liquid fuels to move 97% of civil transport and 100% of military transport in the European Union, and providing about 50% of the inputs used by the chemical industry and all essential products such as bitumen for asphalt, lubricants, waxes and solvents vital for agriculture, construction and health.
While in Europe 35 refineries have closed since 2009, losing about 20% of total capacity. According to sectoral data, Spain has increased its capacity by around 13% in the last two decades, maintains 8 operational refineries, and is among the European countries with the highest refining capacity. This investment strength makes it possible to self-produce around 80% of the kerosene consumed by the country and cushion geopolitical shocks and price volatilities in international markets.
A multi-energy center is a traditional refinery converted to produce renewable fuels, renewable hydrogen and other energy vectors together with conventional products. Transforming complexes already in operation allows capital investment costs to be reduced by between 30% and 50% compared to building plants from scratch, taking advantage of the logistics, transport connections and technical knowledge already installed to scale the production of renewable fuels quickly and economically.
In addition to gasoline, diesel, kerosene and LPG, asphalt bitumen for roads, industrial lubricants, waxes, solvents, insulators and industrial additives are derived from refining, as well as about 50% of the chemical raw materials (naphthas, aromatics, olefins) used by the manufacturing industry to produce plastics, synthetic fibers, fertilizers, agrochemicals, adhesives, paints or construction materials.
It ensures that all viable technologies compete on a level playing field to reduce CO2 emissions, promoting both renewable electrification and renewable fuels across all means of transport. This avoids relying on a single solution and allows for realistic progress without jeopardizing industrial competitiveness or the affordability of energy for citizens.
Over the last decade, Repsol has allocated an average of approximately €1 billion per year to its five industrial complexes in Spain, including maintenance, modernization, efficiency and production adaptation. This sustained investment makes it possible to operate facilities capable of processing more than 100 different types of crude oil.
