El Andalusian Green Hydrogen Valley It has ceased to be a simple concept and has become one of the most advanced energy projects in southern Europe. Around the facilities of Move In Huelva and Cadiz, an industrial ecosystem is being built that combines renewable hydrogen, biofuels and synthetic fuels with a focus on decarbonizing the refinery, transport and other industrial uses.
Much of the attention has shifted towards Palos de la Fronterawhere the company has decided to concentrate the start of the first phase of the valley. This decision is explained by the existence of self-consumption in the La Rábida energy park as well as the financial and regulatory backing of the administrations, while the Cadiz side of the project, in the Gibraltar FieldIt is progressing at a pace conditioned by the international context of maritime transport.
Why does the project start earlier in Huelva than in Cádiz?
Moeve has explained that the first major stage of Andalusian Green Hydrogen Valley It has been activated in Huelva because the company already had one there. all the necessary elements to consume hydrogen in your own refineryThis makes the business easier to start: there is guaranteed demand from day one and, therefore, less uncertainty when committing large investments.
In the environment of San Roque (Cádiz)The situation is different there. The refinery does not have the same level of internal consumption of green hydrogen, which forces the energy company to build a portfolio of external clients, with special attention to maritime sectorThis commercial nuance is key to understanding why the company has chosen to prioritize the Huelva complex, leaving the Cadiz plant for a later phase, once the rules of the game become clearer on a global scale.
Moeve's commercial and clean energy manager, Carlos BarrasaHe explained that the move responds to a viability criterion: while in Huelva the conditions exist to start producing and consuming renewable hydrogen at home, in Cádiz it is necessary to generate demand linked to maritime transportwhich today depends largely on international regulatory decisions.
With this phased strategy, the company aims to start where the risk is lower and profitability can come sooner, leaving the door open to accelerating investment in the Gibraltar Field as soon as the market and regulations allow.
A regulatory blockage that hinders the maritime part of the valley
The main obstacle to developing the Cadiz side of Green Hydrogen Valley It falls within the realm of regulations. International Maritime Organization (IMO) I had on the table a first global agreement with mandatory targets of emission reduction in maritime transportwhich was intended to serve as a reference for shipping companies and shippers to make investment decisions regarding new ships and alternative fuels.
However, the adoption of that package has been interrupted after a motion promoted by Saudi Arabia and supported by the United Stateswhich has led to a one-year suspension of the negotiation process. This pause delays the planned timetable for the entry into force of stricter measures from 2028 onwards and has created a climate of regulatory uncertainty which is noticeable throughout the entire value chain.
In this context, Many shipping companies have decided to postpone the renewal of their fleets or the procurement of clean fuels on a massive scale. The logic is simple: without clear requirements and fixed deadlines, it is more difficult to justify costly investments in new technologies internally, however well-established the discourse on decarbonization may be.
For Moeve, this translates into its investment commitments in San Roque will have to synchronize with the steps taken by maritime transportThe company is keeping the Cadiz project alive and assures that it is working with various partners to fit the commercial and financial pieces together, but assumes that the pace of progress will depend largely on how the international framework for low-emission fuels in ports evolves.
Onuba Project: the heart of the valley in Palos de la Frontera
Meanwhile, the Huelva part of Andalusian Green Hydrogen Valley has taken decisive steps. Moveve has approved the final investment decision for the call Onuba Projectwhich acts as the industrial hub of the valley in Palos de la Frontera and will involve an investment of around 1.000 millones de euros in its first phase.
This action includes the construction of a 300 megawatt (MW) electrolyzerwith the possibility of expanding capacity by an additional 100 MW. This facility will be dedicated to generating renewable hydrogen both for the own consumption of Moeve's plants in the energy park of La Rabida as well as to supply third-party industrial clients seeking to reduce their emissions.
In the corporate structure, Moeve maintains a majority stake of 51% in this first stage, while the Abu Dhabi fund masdar and the company Enalter They join as minority partners. Enalter, majority-owned by Enagas RenovableThis reinforces its presence in the hydrogen value chain and positions it in a project destined to have a significant impact on the European map.
Onuba is not limited to the electrolysis plant: it also integrates renewable generation facilities to power the process and a set of internal infrastructures that will allow the management of different streams of hydrogen and derived products within the energy park, optimizing flows and costs.
Luxia and the Innovation Fund: Europe's commitment to Huelva
One of the key components of the Huelva deployment is luxia, the project with which Moeve presented itself to the 2024 call for proposals for the Innovation Fund (IF24) of the European Union. This initiative is designed to demonstrate the first large-scale production of renewable hydrogen, both of biological and non-biological origin, and of two strategic derivatives: Green methanol and renewable ammonia.
According to the information sent to Brussels, Luxia corresponds to the central production plant of the Andalusian Green Hydrogen Valley in Huelva, nestled within the broader umbrella of Onuba ProjectThe Innovation Fund has awarded this proposal 203 millones de euros, aid that is integrated into a community program of 2.700 million intended for net-zero emissions technologies.
This European funding is in addition to the over 300 million euros of NextGenerationEU funds previously awarded to the Huelva valley, under its classification as Project of Common European Interest (IPCEI / PCI)The combination of both sources positions the Moeve initiative as one of the projects with the greatest public support in southern Europe in the field of renewable hydrogen.
Within the La Rábida energy park, the project will deploy a “hydrogen ring” which will act as an internal distribution system. This scheme will link the green hydrogen plant, The HR3 treatment plant, the production facility of HVO (second generation biofuel) and other units, with a system designed to combine different sources of renewable hydrogen and adjust the supply to each customer in real time.
Capacity, investment and employment: the dimension of the Andalusian Valley
If both the Huelva plant and the one planned in are taken into account San Roque, the Andalusian Green Hydrogen Valley aspires to achieve a total electrolysis capacity of 2 gigawatts (GW) once both are fully operational. At that scale, the complex could produce on the order of 300.000 tons of green hydrogen per year, a figure that places it among the major European initiatives in the sector.
The planned joint investment for the valley is around 3.000 millones de euros distributed between the two production centers in Huelva and Cádiz. If parallel projects in the surrounding area, such as the biofuels plant, are included, some estimates raise the total effort to nearly 2.200 billion euros in just the two large facilities in Huelva, reflecting the magnitude of the investment commitment.
In terms of employment, the calculations used by the company and the administrations point to the creation of up to 10.000 jobs between direct, indirect, and induced costs throughout the different phases of construction and operation. At the Palos biofuels plant alone, there are already around 500 people working on the construction site, with expected peaks of up to 2.000 workers when the most intense phase of assembly is reached.
The roadmap is not limited to the supply of hydrogen as such. The valley's industrial plan includes boosting the production of advanced biofuelssustainable aviation fuels and synthetic derivatives such as methanol and green ammonia, key to decarbonizing sectors that are difficult to electrify directly, such as maritime and air transport or certain branches of heavy industry.
Construction schedule and connection to the biofuels plant
The Minister of Industry, Energy and Mines of the Regional Government of Andalusia, Jorge Paradela, recently detailed the planned schedule for the deployment in Huelva. This was conveyed after a technical visit to the energy park of La Rabida, the works on the Huelva side of the valley, that is, the Onuba ProjectThey are scheduled to begin throughout this semester, with the aim that the Green hydrogen production to start in 2029.
Meanwhile, construction of the Moeve's 2G biofuels plant in Palos de la Frontera, already considered as the largest production complex for these renewable fuels in southern EuropeThe investment associated with this unit is around 1.200 millones de eurosAnd the company's forecast is that it will begin production at the end of 2026This will allow its entry into service to overlap with the development of the valley.
Paradela has emphasized the Interrelationship between the biofuels plant and the hydrogen valleyIn its initial phase, the Palos facility will focus on manufacturing second-generation biofuels and sustainable aviation fuels. Later, when the valley produces renewable hydrogen on an industrial scale, it will also have... raw material for the production of synthetic fuels (e-fuels), highly valued by the European Union, which has set specific objectives for its use in aviation and potentially in other modes of transport.
These synergies explain why the Andalusian administrations speak of a “world reference center for green molecules” in Huelva. The works, both of the biofuels plant and the Onuba project, are technically complex, but the official narrative insists that both are progressing well and that the deadlines, although conditioned by factors such as the expansion of the capacity of the electricity gridThey remain within the expected margins.
Institutional impetus and positioning of Spain in Europe
Institutional support for Andalusian Green Hydrogen Valley It comes from several fronts. In addition to the Junta de Andalucía, which has streamlined permits through its Project Accelerator Unit and has processed authorizations in about six months, the Central Government and the European Commission They have injected resources through various calls for aid.
In the final round of Innovation Fund (IF24)The European Commission distributed 2.700 millones de euros across 54 projects from 17 European countries linked to sectors such as refining, cement, steel, renewable energy, and transport. Moeve's project in Huelva is among those receiving the highest funding: 203 millones de euros, second only to an Italian cement decarbonization initiative (Dream), endowed with 216 million.
In this distribution, Spain is positioned as the second country with the most selected projectswith six supported initiatives, second only to France. In addition to luxia, have obtained European funding proposals such as VB1F (turbines with microlaminated wood for existing wind farms), Connect2 Sea (maritime transport of liquid CO₂ in the Mediterranean), AUTO (plasterboards with lower energy and water consumption), Green Heat Asturias (electrification of industrial heat using photovoltaics) and Inspire-PV (recovery of photovoltaic equipment), which reinforces the image of Spain as an emerging hub for climate innovation.
During the development phase of these projects, the European Climate, Infrastructure and Environment Executive Agency (CINEA) It will support the developers to ensure that the requirements of the Innovation Fund are met and facilitate progress towards financial closure and construction. Looking ahead to the next call for proposals in 2025, the Commission has announced an even larger budget of 2.900 millones de eurosThis opens the door for new developments linked to hydrogen and renewable fuels to be submitted to these programs.
Moves in the Spanish renewable hydrogen ecosystem
Beyond its own projects, Moeve is reinforcing its role in the Spanish green hydrogen ecosystemThe company has recently joined the alliance as a promoting partner. SHYNE (Spanish Hydrogen Network), a platform that brings together large energy, industrial and technology companies to promote projects for the production, logistics and use of renewable hydrogen throughout the country.
SHYNE, which already had promoters like Alsa, Bosch, Enagás, Enagás Renovable, Navantia Seanergies, Repsol or Talgo, has also added Exolum as a new promoting partner. With these additions, the association strengthens both its capacity to logistical deployment —in the case of Exolum, which specializes in the storage and transport of liquid and gas bulk cargo— as its muscle in the large-scale production phase, in which Moeve aspires to become one of the leading figures.
The company's management insists that Spain has competitive renewable resources, a mature energy infrastructure network, and favorable climatic conditions. to generate large volumes of green hydrogen and synthetic fuels at reasonable costs. In this sense, alliances like SHYNE are seen as a way to coordinate the value chain, share risks, and accelerate the implementation of high-impact projects such as the Andalusian Green Hydrogen Valley.
With European financial support, regional regulatory guidance, and participation in sectoral consortia, Moeve is trying to position Andalusia—and especially... Huelva and the Gibraltar Field— on the map of futures European hydrogen corridors, which are expected to facilitate the exchange of green molecules between production centers and large consumer hubs.
This entire network of projects, alliances, and institutional support paints a picture in which the Andalusian Green Hydrogen Valley It acts as a central piece of the energy transformation in southern Spain: Huelva is consolidating its position as a spearhead with Onuba and Luxia, supported by the large biofuels plant and a robust package of European aid, while San Roque is progressing more cautiously, awaiting the finalization of the maritime transport regulatory framework. If the deadlines are met and the investments materialize, the entire valley could become one of the most important renewable hydrogen industrial hubs in Europe, with the capacity to supply green molecules, biofuels, and e-fuels to various sectors and strengthen Spain's energy competitiveness.
