Renewable diesel for a cleaner tomorrow

Solar diesel

Synhelion’s renewable diesel cuts fuel-related CO₂ emissions by up to 99% compared to fossil diesel. As a drop-in solution, our solar diesel directly replaces fossil fuels without compromising on performance. Our diesel is compatible with existing engines and infrastructure, making it an immediate and effective way to reduce emissions.

This is the future of transportation – sustainable, scalable, and ready today.

Key characteristics and benefits

Sustainability

Produced from RED-II-compliant biomass waste and solar energy, Synhelion’s solar diesel reduces lifecycle CO₂ emissions by up to 99% compared to fossil fuels.

Compatibility

Synhelion’s solar diesel is a drop-in fuel that is compatible with today’s infrastructure and engines. No modifications are needed to storage facilities, distribution infrastructure, fuel systems, or engines.

Performance

Synhelion’s solar diesel delivers the same range and engine performance as fossil diesel, ensuring uncompromised efficiency.

Compliance

Synhelion’s solar diesel is fully compliant with national and international diesel standards. Our solar diesel meets the specifications of EN 15940 and international equivalents, and it can be mixed with fossil diesel.

Air quality

Due to the absence of impurities like aromatics found in fossil fuels, our solar diesel burns cleaner, contributing to improved air quality around the world.

Renewable diesel in action

Synhelions fuels steamboat with solar diesel

Solar fuel hits the water. For the first time ever, Synhelion has fueled a ship with its renewable solar diesel produced at plant DAWN. An over 110-year-old steamboat was symbolically fueled with Synhelion’s first barrel of solar diesel. A milestone for more sustainable mobility on the water.

Synhelion fuels passenger bus with solar diesel

Synhelion and Zurich Airport have reached another milestone on the road to more sustainable transportation solutions: for the first time, a passenger bus at Zurich Airport has been fueled with solar diesel from Synhelion’s DAWN plant. Synhelion has thus proven that the technology is ready for deployment and the next phase of scaling.

Global CO₂ emissions
Together, shipping and heavy transport accounts for around 6.5% of global CO₂ emissions.

Market size
Demand for renewable heavy transport and marine fuel is expected to reach 138 million tons per year by 2050.

Defossilization strategy
Sustainable fuels play a crucial role in defossilizing shipping and heavy transport.

Our solar diesel customers

Zurich Airport

Zurich Airport has signed a five-year offtake agreement from 2027 for renewable diesel with Synhelion. The renewable diesel will initially be used to power the airport’s passenger buses and later to fuel special non-electric vehicles.

Lake Lucerne Navigation Company

Lake Lucerne Navigation Company (SGV) AG, a leading Swiss transportation company, has signed a five-year fuel offtake agreement with Synhelion. From 2027, the company will purchase solar diesel to power its historic steamboats.

Lenzerheide Bergbahnen AG

Lenzerheide Bergbahnen AG, a leading Swiss tourism company, has signed a long-term offtake agreement for solar diesel with Synhelion. The renewable fuel will be used in the snow groomers of the Arosa Lenzerheide ski area for slope preparation starting from the 2027/2028 season.
