Toyota Moves to Join Volvo and Daimler Truck in cellcentric, Creating a Three-Way Fuel Cell Alliance for Heavy-Duty Transport

Toyota Motor Corporation is set to deepen its role in hydrogen mobility by seeking an equal stake in cellcentric, the fuel cell joint venture currently owned by Volvo Group and Daimler Truck. Under a newly signed non-binding agreement, the three companies intend to establish Toyota as a third equal shareholder, creating a broader industrial alliance focused on developing, producing, and commercializing fuel cell systems for heavy-duty transport and other applications with similar performance requirements.

The proposed move is significant because it brings together three different strengths within one platform. Volvo and Daimler Truck contribute deep commercial vehicle expertise and direct market access in heavy-duty transport, while Toyota adds more than three decades of fuel cell development experience built largely in the passenger vehicle sector. By combining those capabilities, the companies are aiming to improve the technical maturity, production readiness, and commercial viability of hydrogen fuel cell systems in one of the hardest segments to decarbonize.

 

A Strategic Expansion of cellcentric’s Industrial Base

 

cellcentric was established in 2021 as a joint venture between Volvo Group and Daimler Truck, with the goal of building fuel cell systems for heavy commercial vehicles and related applications. Toyota’s planned entry would significantly expand that industrial base, not only by adding another global automotive manufacturer, but by broadening the venture’s technical foundation and manufacturing know-how.

The three companies say the intention is for cellcentric to remain an independent and autonomous entity even after Toyota joins, serving a wide range of customers across heavy-duty on-road and off-road transport as well as heavy-duty stationary applications. That point matters because the venture is not being framed as a captive supply operation for only its shareholders. Instead, it is being positioned as a dedicated center of competence for fuel cell systems, capable of supplying a broader heavy-duty market.

This structure also suggests that the partners see scale as essential to making hydrogen fuel cell technology commercially competitive. In heavy transport, development costs are high, market uptake remains uneven, and infrastructure is still limited. A shared platform can reduce duplication, improve investment efficiency, and help create the production volume needed to lower system costs over time.

Toyota’s Role Extends Beyond Shareholding

 

Toyota’s involvement is expected to go beyond financial participation. In addition to joining as an equal shareholder, Toyota and cellcentric intend to jointly manage the development and production of fuel cell unit cells, which are the core building blocks of fuel cell systems, along with related architecture and control elements.

This is a critical aspect of the agreement because the unit cell sits at the center of fuel cell performance, efficiency, durability, and cost. By bringing Toyota’s long-standing fuel cell engineering experience into direct collaboration with cellcentric, the partnership is trying to strengthen the technical competitiveness of the systems it ultimately brings to market.

The emphasis on combining technologies from both Toyota and cellcentric suggests that the alliance is not merely about scaling what already exists. It is also about improving product design and manufacturing capability in a way that can support more competitive commercial deployment. That could be particularly important in heavy-duty transport, where operators are unlikely to adopt fuel cell systems at scale unless performance, reliability, and total cost of ownership improve materially.

 

Hydrogen Is Being Positioned as a Complement to Battery Electric Transport

 

The proposed three-way alliance also reinforces a wider strategic view shared by the companies: that hydrogen should play a meaningful role alongside battery-electric systems in decarbonizing transport. Daimler Truck explicitly stated that hydrogen must complement battery-electric drivetrains, rather than be seen as an alternative that replaces them entirely.

That is an important framing. In passenger cars, battery-electric technology has moved ahead much faster than hydrogen. In heavy-duty transport, however, the picture remains more open because vehicle range, payload, refueling time, and infrastructure constraints vary widely across use cases. For long-haul, high-utilization, and certain off-road applications, fuel cells remain one of the technologies being seriously considered for zero-emission operation.

The cellcentric expansion therefore reflects a belief that hydrogen still has a strategic future in transport, especially in segments where battery systems may face technical or operational limitations. By increasing collaboration at the system-development level, Volvo, Daimler Truck, and Toyota are effectively signaling that fuel cell technology needs industrial consolidation and shared commitment if it is to become a viable part of the heavy-duty transition.

Infrastructure Remains a Central Constraint

 

The companies also acknowledged that fuel cell commercialization cannot be separated from the wider hydrogen ecosystem. Alongside system development, they said they intend to work with industry associations and partners across the hydrogen value chain to support the development of supply and infrastructure in the early stages.

This is a crucial point because hydrogen vehicle adoption depends not only on the quality of the fuel cell systems themselves, but also on whether hydrogen production, distribution, and refueling infrastructure can scale in parallel. Without that supporting network, even technically mature fuel cell vehicles will struggle to achieve widespread market penetration.

The collaboration therefore appears to be built around a dual assumption. First, fuel cell systems need more scale, deeper technical collaboration, and lower production costs. Second, infrastructure growth will require coordinated effort across multiple industrial actors, not just vehicle manufacturers. The alliance is trying to strengthen the first part while helping advocate for the second.

 

A Signal of Consolidation in Heavy-Duty Decarbonization

 

The broader significance of Toyota’s planned entry into cellcentric is that it reflects a more collaborative phase in transport decarbonization. Heavy-duty zero-emission technologies remain expensive to develop and uncertain in terms of market timing. Under those conditions, partnerships become more attractive because they spread cost, pool expertise, and increase the chance of reaching commercial scale.

Volvo, Daimler Truck, and Toyota will continue to compete independently in all other areas of their businesses, which means this is a focused collaboration rather than a broader strategic merger. Even so, the decision to pursue equal ownership in a hydrogen fuel cell venture is a strong signal that the companies view cooperation as necessary if fuel cells are to become a serious commercial technology for trucks and other heavy-duty applications.

The agreement remains non-binding for now, and a legally binding deal will still need approval from the companies, boards, and relevant authorities. But the direction is already clear. If completed, Toyota’s entry into cellcentric would create one of the most significant fuel cell alliances in the heavy-duty transport sector, strengthening the industrial case for hydrogen at a time when the sector is still searching for scalable pathways to deep decarbonization.
