Understanding Cespira: A Name with a Mission
The name 'Cespira' itself is a testament to the JV's core objective. As explained by Dan Sceli, CEO of Cespira, it thoughtfully combines 'espira'—meaning 'breathe out'—with 'C' for 'clean'. This linguistic fusion perfectly encapsulates their commitment to reducing harmful emissions and fostering a healthier environment. The visual identity of Cespira further reinforces this mission: the distinctive turquoise symbol nestled above the 'i' in the logo is far more than a mere design element. It symbolises the collaborative spirit between Volvo Group and Westport, the seamless integration of established technologies with cutting-edge clean fuel solutions, and, crucially, the molecular structure of hydrogen, which stands at the very heart of Cespira's future ambitions. Moreover, this symbol reflects a broader aspiration: to forge partnerships with multiple Original Equipment Manufacturers (OEMs), thereby expanding the reach and impact of their groundbreaking technology across the industry. Collaboration, as Cespira asserts, is fundamental to achieving true decarbonisation.
The Power Behind Cespira: HPDI Fuel System Technology
At the core of Cespira's offering is the patented High-Pressure Direct Injection (HPDI) fuel system technology. This isn't just another incremental improvement; it's a transformative solution designed to enable internal combustion engines (ICEs) to operate with significantly reduced emissions, and even with carbon-neutral or fossil-free fuels. What makes HPDI particularly compelling is its ability to integrate seamlessly into existing ICE architectures. This means that fleets and manufacturers don't necessarily need to overhaul their entire powertrain infrastructure to benefit from cleaner operations. Instead, HPDI offers a viable pathway to decarbonisation by allowing current engines to run on alternative fuels.
How HPDI Redefines Fuel Compatibility
The beauty of HPDI lies in its versatility regarding fuel sources. While traditional ICEs are largely limited to fossil fuels, HPDI technology unlocks the potential of a diverse range of cleaner alternatives. Currently, it offers substantial CO2 reductions when utilising biogas and natural gas. Looking ahead, the technology holds immense promise for hydrogen—a truly zero-emission fuel at the point of use. This adaptability ensures that vehicles can transition away from fossil fuels, such as diesel, towards more sustainable options like bio-fuels, e-fuels, or green hydrogen, all without compromising on the critical aspects of performance and efficiency that are vital for demanding applications like long-haul trucking and heavy-duty off-road uses.
Key Advantages of HPDI Technology:
- Significant CO2 Reductions: Offers immediate and substantial cuts in greenhouse gas emissions.
- Fuel Versatility: Compatible with biogas, natural gas, e-fuels, and poised for hydrogen.
- Integration into Existing ICEs: Avoids the need for entirely new engine designs, simplifying adoption.
- Uncompromised Performance: Maintains the power, torque, and efficiency expected from heavy-duty engines.
- Scalability: Designed to overcome barriers to adoption and expand access across the mobility sector.
Decarbonisation for the Heavyweights: Long-Haul and Off-Road
The impact of HPDI technology on decarbonisation is particularly significant for sectors that rely heavily on robust internal combustion engines. Long-haul trucking, which forms the backbone of global logistics, and demanding off-road applications, such as construction and mining, are prime candidates for Cespira's solutions. These sectors face unique challenges in transitioning to fully electric solutions due to range requirements, payload demands, and charging infrastructure limitations. HPDI offers a pragmatic and powerful intermediate step, providing immediate reductions in greenhouse gas emissions while leveraging existing engine technology and refuelling infrastructure that can be adapted for cleaner fuels.
Lars Stenqvist, CTO at Volvo Group, underscored this point, stating, "The HPDI technology is important for decarbonisation, offering immediate reductions in greenhouse gas emissions while utilising existing ICE. This can be achieved today with biogas and natural gas, and we foresee exciting possibilities with hydrogen." This sentiment highlights HPDI as a bridge technology, capable of delivering tangible environmental benefits in the present while laying the groundwork for a hydrogen-powered future.
Volvo's Strategic Investment and Vision
The establishment of Cespira in 2024 represents a significant strategic move for both Volvo Group and Westport Fuel Systems. Volvo Group holds a 45% interest in the JV, committing approximately $28 million initially, with potential for an additional $45 million as an earn-out. This substantial investment by Volvo underscores their strong belief in HPDI technology as a crucial component of their long-term sustainability strategy. Volvo aims to exploit the opportunities presented by Cespira to further develop and test its trucks equipped with hydrogen-powered internal combustion engines. This foresight positions Volvo, through Cespira, at the forefront of the industry's shift towards more sustainable heavy-duty transport solutions.
The collaboration is not just about financial investment; it's about pooling expertise. Volvo brings its extensive experience in heavy-duty vehicle manufacturing and market reach, while Westport contributes its patented HPDI technology and deep understanding of advanced fuel systems. This synergy is designed to accelerate the development and commercialisation of clean fuel solutions, making them accessible and effective for a wider range of OEMs and applications.
HPDI Technology vs. Traditional Diesel: A Comparative Glance
To truly appreciate the advancements brought forth by Cespira's HPDI technology, it's helpful to consider how it stacks up against traditional diesel engines, which have long been the workhorses of heavy-duty transport.
HPDI Fuel System vs. Traditional Diesel Engine

Overcoming Barriers and Expanding Reach
A key focus for Cespira is to overcome the existing barriers to the adoption of advanced clean fuel technologies. While the benefits of HPDI are clear, widespread implementation requires addressing challenges related to infrastructure, cost, and OEM integration. By creating a dedicated joint venture, Volvo and Westport aim to streamline the development, manufacturing, and commercialisation processes, making HPDI technology more accessible and attractive to a broader market. Their ambition to partner with multiple OEMs is central to this strategy, ensuring that the impact of their clean fuel solutions extends far beyond their own product lines.
