Spain’s renewable hydrogen bet: A test for the EU’s hydrogen ambitions

Spain combines the EU’s lowest‑cost renewable electricity with a deliberately constructed, policy‑backed hydrogen strategy aimed at industrial scale and export leadership. Rather than deploying all its cheap renewable power primarily to accelerate direct electrification, Spain has made the choice to push renewable hydrogen as an industrial policy instrument and future export product. This strategy rests on intentionally oversized electrolyzer targets, substantial public funding, and the build‑out of export‑oriented infrastructure.

However, potential export demand remains largely dependent on EU‑level policy mandates outside Spain’s control. Spain’s hydrogen trajectory therefore represents a critical test case: Success would validate the EU’s large-scale hydrogen ambitions, while failure would expose structural weaknesses in the EU’s hydrogen decarbonization strategy. In this strategy, renewable hydrogen is positioned as one of the cornerstones of the EU energy transition, targeting a demand of 20 million metric tons (MMT) by 2030, of which 50% is produced domestically and 50% is imported from outside the EU.

Over the past decade, Spain has rapidly expanded its renewable electricity production capacity, nearly doubling installed capacity to 89GW by 2024. Within the EU, only Germany exceeds this figure, with approximately 177GW of installed renewable capacity. However, capacity alone does not determine price competitiveness.

Despite Germany’s larger renewable electricity capacity, Spain benefits from the one of the lowest levelized cost of electricity (LCOE) in the EU. In 2024, the lowest solar photovoltaic (PV) generation costs in Spain were EUR 34.04/MWh, while the lowest-cost onshore wind generation was EUR 39.56/MWh.[1] High solar irradiation, favorable wind resources, and declining technology costs combine to deliver consistently low wholesale electricity prices. As wind and solar generation have near‑zero marginal costs, increasing their share in the electricity mix structurally suppresses wholesale prices.

Electricity prices are the dominant cost component of renewable hydrogen production, typically accounting for 40% to 60% of the levelized cost of hydrogen (LCOH). Reflecting its electricity cost advantage, Spain recorded the lowest LCOH in the EU in 2023 (EUR 6.71/kg) and is projected to retain this position in 2025 (EUR 5.95/kg) and beyond.

This abundance of low‑cost renewable electricity provides Spain with a genuine structural advantage in hydrogen production. However, this advantage does not automatically mean that hydrogen is the most efficient or effective use of renewables from a climate perspective. Direct electrification, where possible across industry, transport, and buildings, would deliver faster and cheaper emissions reductions per unit of renewable electricity deployed. Thus, Spain’s decision to channel a significant share of renewable electricity toward hydrogen reflects a strategic choice rather than a techno‑economic necessity.

Rather than maximizing near‑term emissions reductions through electrification, Spain has chosen a strategy to position itself as the EU’s renewable hydrogen production and export hub. This strategic choice prioritizes long‑term industrial positioning, value‑chain development, and geopolitical relevance over least‑cost emissions abatement.

Spain’s hydrogen strategy is anchored in the Hydrogen Roadmap (Hoja de Ruta del Hidrógeno), published in October 2020. The road map integrates regulatory reform, sector‑specific deployment measures, and the deliberate clustering of supply and demand through regional hydrogen valleys.

Initially, the road map set a target of 4GW of installed electrolyzer capacity by 2030. This target was subsequently tripled to 12GW in the updated National Integrated Energy and Climate Plan 2023-2030 (PNIEC). Crucially, this upward revision was not necessarily driven by a reassessment of domestic hydrogen demand. It rather seems intentionally oversized relative to foreseeable domestic needs in order to secure first‑mover advantages, economies of scale, and export optionality.

Spain’s hydrogen policy does not operate in isolation, but within a layered policy stack that collectively defines the architecture of its emerging hydrogen economy:

Taken together, this policy stack reveals hydrogen as a central pillar of Spain’s industrial repositioning strategy: climate‑aligned, yet driven by industrial policy priorities rather than short‑term decarbonization efficiency.

If the policy framework defines intent, the Strategic Project for Economic Recovery and Transformation for Renewable Energy, Green Hydrogen and Storage (PERTE ERHA) translates that intent into physical assets. The PERTE ERHA functions explicitly as an industrial policy tool. Unlike neutral climate instruments that often prioritize least‑cost emissions abatement, the project is designed to maximize industrial scale, domestic value creation, and long‑term competitiveness, accepting higher near‑term abatement costs as the price of strategic positioning.

Spain’s renewable hydrogen strategy is supported by a complex stack of funding instruments totaling roughly EUR 7bn, primarily structured as grants. Funding is sourced mainly from EU programs, including the Recovery and Resilience Facility and REPowerEU, and is coordinated at the national level under PERTE ERHA. A cornerstone of this approach is the hydrogen valleys program, which concentrates support on large industrial clusters in Aragón, Andalusia, Castile and León, Catalonia, and Galicia. This place‑based approach favors industrial anchoring and scale over geographically dispersed, lowest‑cost projects.

Despite the scale of Spain’s ambition, execution has lagged. More than 43 hydrogen projects have been announced since 2020, spanning research, demonstration, and commercial applications. However, consistent with global hydrogen trends, many projects remain in early development stages. Only a limited number have reached final investment decision (FID) or entered operation. As of early 2026, electrolyzer capacity for projects that are operational or beyond the FID stage totals approximately 570MW.

This gap between ambition and delivery is stark. With operational capacity of roughly 30MW and a delayed pipeline of around 540MW, Spain remains far from its 12GW 2030 target. Based on typical assumptions regarding load factors and efficiency, 540MW of electrolyzer capacity would produce approximately 44 kilotons (kt) of hydrogen per year. At full realization of the target, 12GW could yield around 980kt annually, but this remains a theoretical upper bound rather than a realistic near‑term outcome.

Renewable hydrogen demand in Spain, and in the EU more broadly, is almost entirely policy‑manufactured. Under the revised Renewable Energy Directive (RED III), member states must ensure that 42% of industrial hydrogen consumption is renewable by 2030. RED III also introduces a 1% renewable fuel of non‑biological origin (RFNBO) target for the transport sector, defined as a share of total transport energy consumption. RFNBO refers to renewable hydrogen and hydrogen‑derived fuels such as renewable ammonia and renewable methanol.

However, RED III allows substantial national discretion in implementation. And, despite the deadline by 2025, Spain has not yet transposed RED III into national law. In its draft Transport Decarbonization Decree from 2026, Spain proposes a voluntary system for RFNBO use in industry, with credits tradable to the transport sector. By contrast, RFNBO use in road transport is made mandatory, starting at 0.7% of the energy pool in 2028 and rising to 2.5% by 2030, with at least 1.5 percentage points of this obligation falling on the refinery sector.

Based on Spain’s 2024 road transport energy consumption of approximately 1.21m terajoules, the 2028 obligation would create demand for around 70kt of hydrogen used in RFNBOs, rising to approximately 250kt by 2030. This figure represents gross demand prior to the application of flexibility mechanisms, such as multipliers or double counting.

Other transport sectors in Spain currently face no RFNBO consumption obligation, with aviation being the notable exception. Aviation is not governed by RED III but by the sector‑specific ReFuelEU Aviation regulation, which sets binding RFNBO mandates at the EU level. Unlike directives, regulations require no national transposition and apply directly and uniformly across all member states upon entry into force.

It is hard to find reliable data about jet fuel consumption in Spain. Estimates suggest consumption of around 7.5MMT per year in 2023. When applying the 2030 RFNBO requirement of 1.2%, this results in demand amounting to 30kt per year for e-kerosene production.

In aggregate, road transport and aviation obligations could generate approximately 280kt per year of RFNBO demand by 2030. This figure represents gross demand prior to the application of flexibility mechanisms, such as multipliers or double counting. It also abstracts from the fact that RFNBO obligations under RED III and ReFuelEU Aviation are defined in final energy terms, rather than in tons of hydrogen. Converting these energy‑based targets into precise hydrogen volumes therefore requires explicit assumptions regarding fuel production pathways, conversion efficiencies, and lower heating values.

Demand of 280kt is more than six times what Spain can currently produce with its existing and near‑term electrolyzer capacity, but 3.5 times less than what 12GW installed electrolyzer capacity could roughly produce. Crucially, future demand growth depends not on Spanish policy alone, but on the transposition and enforcement of RED III obligations in hydrogen‑importing countries such as Germany and the Netherlands. Demand risk therefore lies largely outside Spain’s control.

As questions emerge around whether Spain can scale domestic hydrogen production quickly enough, North Africa is often cited as a potential complementary supply source. The region combines strong solar and wind resources with geographic proximity to southern Europe, making it a recurring reference point in EU hydrogen debates. Spain does not intend to become structurally dependent on hydrogen imports from North Africa. Instead, potential imports could reinforce Spain’s role as a transit and aggregation hub rather than an end market.

While Spain is geographically well positioned to receive hydrogen or derivatives from North Africa, this part of the strategy remains largely hypothetical. Supplier countries, notably Morocco, are still in early phases of hydrogen strategy development, with unresolved questions around production costs, water availability, domestic prioritization, and geopolitical risk. In practice, North African imports represent option value rather than a credible near‑term supply source and cannot be relied upon to mitigate risks for either Spain’s or the EU’s hydrogen strategy within this decade.

Spain’s hydrogen strategy is best understood not as a response to near‑term decarbonization needs, but as a long‑horizon industrial policy built on a structural advantage: the EU’s lowest‑cost renewable electricity. By intentionally oversizing electrolyzer targets relative to projected domestic demand, Spain is seeking to lock in a first‑mover position as the EU’s renewable hydrogen supply hub.

This strategy may succeed in creating a competitive hydrogen industry. However, it entails significant execution risk, large upfront investment ahead of market maturity, and heavy reliance on policy‑mandated demand in external markets. Spain’s ability to translate ambition into timely project delivery, and the willingness of other EU member states to enforce hydrogen demand mandates, will ultimately determine the outcome.

Spain’s hydrogen trajectory therefore represents a decisive test case for the EU’s hydrogen ambitions. If Spain, with the EU’s best electricity economics and strong policy support, cannot make hydrogen work at scale, the prospects for an EU-wide decarbonization strategy involving hydrogen will be fundamentally called into question.
