Description

To preserve Swiss cultural heritage while advancing sustainability, Synhelion and SGV AG launched a world-first initiative: powering the iconic 110-year-old steamboat Gallia on Lake Lucerne with Synhelion’s renewable solar diesel. These historic vessels cannot be electrified without compromising their original engines, key to their heritage. The solar fuel comes from Synhelion’s first production plant DAWN in Jülich, Germany, which has been producing sustainable, synthetic fuels on an industrial scale since summer 2024: a renewable drop-in fuel that requires no modifications to existing engines and infrastructure. By integrating cutting-edge technology into a traditional setting, this project sets a powerful precedent for defossilizing hard-to-electrify transportation sectors. It combines innovation and cultural preservation in a scalable model for sustainable mobility, setting a new standard for renewable marine fuels and more sustainable mobility on the water.

Impact & Result

SGV and Synhelion are pioneering sustainable maritime mobility. SGV signed a long-term offtake agreement for 100 tons of solar diesel annually starting in 2027. Synhelion’s renewable fuel reduces lifecycle CO₂ emissions by up to 99% compared to fossil diesel, enabling SGV to cut around 300 tons of CO₂ each year.

Solution Spotlight

Solar fuels are synthetic fuels produced from solar energy. They are climate-friendly, renewable, and affordable. A cutting-edge technology that offers a truly sustainable alternative to fossil fuels. Synhelion is on a mission to replace fossil fuels by economically viable synthetic fuels. The solution uses high-temperature solar heat to convert water and CO2 into synthetic fuels; so-called solar fuels. These fuels are compatible with the current global fuel infrastructure and reduce net CO2 emissions by up to 100%. The technology combines state-of-the-art solar tower systems with proprietary high-temperature thermochemical processes for the production of solar fuels.
