This is our history.

A vision coming true.

From theory to fuel production

It all started with a crazy idea at ETH Zurich. What if we could reverse combustion? The idea worked – at first on paper, then in the lab, and finally in the field. In 2016, Synhelion was founded to bring solar fuels to market. With our pioneering technology, we want to create a global impact and effectively reduce CO2 emissions.

Solar fuels enable industries to drastically lower their immediate carbon footprint and develop a roadmap toward complete carbon neutrality. In 2023, we will launch the world’s first industrial solar fuel production plant. Within the next ten years, we are planning to ramp up production capacity to produce 875 million liters of solar fuel per year, enough to cover about half of Switzerland’s jet fuel consumption.
