China-Spain cooperation in the green energy sector has deepened markedly over the past year, with renewable manufacturing, energy storage, and clean technology supply chains emerging as priority areas for bilateral investment. The pattern was reinforced during Spanish Prime Minister Pedro Sánchez’s official visit to China between 11 and 15 April 2026, during which he and his cabinet held a series of business meetings designed to attract Chinese investment into Spain’s energy transition.
It was within that framework that HiTHIUM signed a Memorandum of Understanding for Strategic Investment Cooperation with the Government of Navarra on 15 April. The agreement commits the company to building its first European manufacturing base — a large-scale energy storage cell and battery system facility in the Navarra Autonomous Region — deepening HiTHIUM’s industrial footprint across the continent.
The Deal in Headline Terms
The signed Memorandum of Understanding for Strategic Investment Cooperation with the Government of Navarra establishes the project’s core parameters across location, scale, structure, and timeline.
- Location and Scope
The plant will be built in the Navarra Autonomous Region of northern Spain, an area with an established industrial base in renewable energy components. The facility combines two functions under one roof: lithium-ion cell manufacturing for stationary storage applications, and assembly of complete battery energy storage systems (BESS).
- Investment Size
The first phase of the project carries a planned total investment of approximately €400 million — over RMB 3 billion. Both parties have indicated that subsequent phases will be considered as the facility ramps up.
- Partnership Structure
HiTHIUM and the Government of Navarra will establish a joint venture to develop, construct, and operate the gigafactory. The structure binds the regional government to the project beyond the role of host — it becomes a direct partner in the venture, with corresponding alignment of incentives.
- Project Timeline
The agreement is the culmination of more than two years of engagement between the two sides. According to Navarra’s Minister of Industry, Mikel Irujo, the process involved seven visits by HiTHIUM representatives to Navarra and four trips to China by Navarrese delegations. Operations at the new facility are projected to begin in 2027.
- Employment Impact
The plant is expected to generate approximately 700 direct jobs in Navarra once operational, with additional indirect employment across the regional supply chain.
- High-Level Endorsement
The signing took place in the presence of Prime Minister Pedro Sánchez. Navarra’s President, María Chivite Navascués, signed on behalf of the regional government; HiTHIUM Founder and Chairman Wu Zuyu signed on behalf of the company.
Why Navarra, Why Spain?
HiTHIUM’s choice of Navarra over alternative European jurisdictions rests on a combination of market conditions, regional capabilities, and counterpart engagement.
- A Demanding but Strategic Market
European demand for energy storage is among the strongest in the world, driven by renewable integration targets, grid flexibility requirements, and rising electricity costs. The continent also presents one of the most complex regulatory environments for energy storage manufacturers, with country-by-country variation in permitting, safety, and content standards. Local manufacturing presence is increasingly the precondition for accessing the largest project pipelines.
- Spain’s Structural Advantages
Spain combines political stability, a mature legal framework, and exceptional renewable energy resources — among the highest solar irradiation and wind potential in Europe. These conditions create both end-market demand for storage and an industrial logic for siting production close to that demand.
- Government Responsiveness in Navarra
The Navarrese government’s engagement throughout the courtship period was substantive rather than ceremonial. The pace of decisions — from President Chivite’s site visit to HiTHIUM’s Chongqing facilities in November 2025, through HiTHIUM’s announcement of intent in March 2026, to the April signing — reflects a regional administration prepared to move at the speed required by a major industrial investor.
- Industrial Ecosystem
Navarra has a long-standing wind power industry and a developed supplier base in renewable energy components, mechanical engineering, and power electronics. For an entrant building both cells and systems, that ecosystem reduces the cost and risk of standing up a local supply chain from scratch.
- Talent Pipeline
Navarra’s universities and vocational training institutions feed a labor market already accustomed to advanced manufacturing. For a facility expected to employ around 700 workers across cell production, system assembly, engineering, and operations, that pipeline is critical to ramp.
- Mutual Fit
On the Navarrese side, attracting an internationalizing Chinese energy storage leader fits a regional strategy of positioning Spain as a European clean energy hub. On HiTHIUM’s side, Navarra offers an EU industrial address with all the legal, commercial, and logistical advantages that follow. The result is a project where both parties have substantive reasons to push it forward.
What the Plant Means for HiTHIUM?
Beyond the project’s external commercial logic, the Spain commitment reshapes several aspects of HiTHIUM’s internal trajectory.
- A Step Change in Globalization
The Navarra facility is HiTHIUM’s first European manufacturing base — a heavy-asset commitment that brings greater operational complexity but also stronger market entrenchment.
- Brand Elevation Through Bilateral Engagement
HiTHIUM Founder and Chairman Wu Zuyu was invited to speak as a representative of the new energy storage sector at the business meeting between Prime Minister Sánchez and Chinese entrepreneurs in Beijing on 14 April. Inclusion at that level — alongside leaders from other strategic Chinese industries — confirms HiTHIUM’s standing as a peer participant in high-level bilateral economic discussion, not simply as a project counterparty.
- A Hedge Against Trade Volatility
International trade conditions for energy storage are growing more complex, with tariff exposure, content requirements, and political risk shaping where products can be sold competitively. Local European production reduces HiTHIUM’s dependence on any single export route and improves its resilience to shifts in cross-border trade conditions.
- Long-Term Signal to European Customers
For European developers and utilities evaluating supplier risk over 15- to 20-year project lifetimes, a long-dated capital commitment in EU jurisdiction is among the strongest signals a Chinese manufacturer can send. The Navarra investment converts HiTHIUM’s European market intent from contractual undertaking to physical commitment.
Conclusion
Cell and system manufacturing in the EU was, until recently, the domain of European and Korean players, with Chinese entrants confined to supplying cells into European integrators. HiTHIUM’s Navarra plant — alongside the broader wave of Chinese battery investment in Spain — points to a different equilibrium taking shape: one in which Chinese storage technology is increasingly built where it is consumed, on European terms, in partnership with European governments. For HiTHIUM, the Spanish plant is a single facility; for the wider energy transition in Europe, it is a data point in a larger industrial rebalancing that is only beginning.
