Hydrogen Freight Transport: Ambar and Carreras Make It Happen

The revolution in cargo transportation is entering a new era with the introduction of hydrogen as a clean energy source. The collaboration between the brewery Ambar and the logistics company Carreras marks a significant milestone in the quest for sustainable transportation solutions, demonstrating how industries can innovate while reducing their environmental footprint.
This pioneering initiative not only represents a technological advance but also a pivotal shift towards a more sustainable future in logistics. The implications of this project could resonate well beyond the regional context, potentially influencing broader transportation practices across Europe and beyond.
Overview of the Hydrogen Transport Initiative
The joint project between Ambar and Carreras aims to reduce carbon emissions during the transportation of beer from Ambar's factory in Zaragoza to Carreras' central warehouse in the Plaza Logistics Platform. The trial, set to last three months, targets a reduction of 30 tons of CO₂ equivalent emissions.
Such ambitious goals require innovative approaches, especially considering the limitations in the availability of hydrogen-powered vehicles in Spain. To overcome this, the project involves retrofitting a hybrid trailer capable of running on both renewable diesel and hydrogen. This flexibility allows for efficient long-distance travel as well.
Interestingly, the tractor unit for this project, developed by the company EVARM, is based on a model that has achieved two consecutive victories in the Mission 1000 category of the Dakar Rally, showcasing its performance and reliability in alternative energy applications.
Technical Aspects of the Hydrogen-Powered Trailer
The hybrid trailer's design is critical to its operational efficiency. It consumes approximately 16 liters of renewable diesel and 3 kilograms of hydrogen per 100 kilometers. In comparison, a conventional truck typically consumes between 33 to 35 liters of B7 diesel. This remarkable efficiency underscores the potential of hydrogen as a viable fuel source in the transport sector.
Key features of the hydrogen-powered trailer include:
- Hybrid propulsion system utilizing both renewable diesel and hydrogen.
- Significant reduction in fuel consumption compared to traditional diesel trucks.
- Engine technology derived from a high-performance racing background, ensuring reliability and efficiency.
Impact on Carbon Emissions
The reduction of carbon emissions is at the heart of this initiative. With a target of decreasing CO₂ emissions by 30 tons during the trial period, the project serves as a case study for others in the industry. Such reductions can significantly contribute to the broader goals of environmental sustainability and climate action.
Ambar and Carreras are committed to not just delivering products but doing so with a conscience. Enrique Torguet, the director of Communication, Institutional Relations, and ESG at Ambar, emphasized: “We want beer to arrive not only freshly packaged but also with fewer emissions.” This statement reflects a growing trend among companies to prioritize sustainability in their operations.
Award Recognition and Future Prospects
The innovative approach taken by Ambar and Carreras has not gone unnoticed. The initiative was awarded the Innovation Award at the Green Gas Mobility Summit 2025, highlighting its significance in promoting hydrogen technologies in heavy transportation.
Looking ahead, this project is expected to serve as a benchmark for future initiatives involving hydrogen in logistics. According to Héctor Benito Serón, the director of projects and sustainability at Carreras, “this test will allow us to understand the practical daily behavior of hydrogen technology in logistics.”
The Broader Context of Hydrogen in Transportation
The transition to hydrogen as a fuel source is not just an isolated initiative. It reflects a broader trend towards decarbonizing the transportation sector. Many countries and companies are exploring hydrogen's potential as a clean energy source for various applications, including:
- Public transport systems, such as buses and trains.
- Heavy-duty freight transportation.
- Maritime transport, with efforts to develop hydrogen-powered ships.
As technology matures and infrastructure develops, the use of hydrogen may become more mainstream, leading to a significant reduction in greenhouse gas emissions across industries.
Conclusion
The collaboration between Ambar and Carreras is a beacon of hope in the pursuit of sustainable logistics. By adopting hydrogen as a fuel source, they are not only addressing the immediate challenges of transportation emissions but also setting a precedent for future innovations in the industry. As the world strives for sustainability, projects like this will play a crucial role in shaping the future of cargo transport.
