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 2024, 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 1 million tons of solar fuel per year.

Our success story

June 2024

Synhelion inaugurated the world’s first industrial-scale plant to produce synthetic fuels using solar heat in Jülich. By inaugurating DAWN, Synhelion proves that our solar fuel technology is ready for large scaling.

June 2024

Synhelion and Pilatus Aircraft Ltd enter into a strategic cooperation with the aim of accelerating the scaling of solar fuels for aviation. Pilatus has also become a shareholder of Synhelion, underpinning its commitment to actively defossilize aviation.

August 2023

Synhelion and Cemex scaled their technology to industrially-viable levels. This includes the continuous production of clinker, the most energy-intensive part of cement manufacturing, using only solar heat.

February/June 2023

The U.S. Department of Energy awarded US$ 3.2 million to Synhelion’s joint project with Cemex and Sandia National Laboratories as well as US$ 2.7 million to the joint project with the University of Florida.

December 2022

Synhelion raises CHF 22 million investment to drive the scaling of solar fuel production. SWISS’ first investment underpins its commitment to bringing Synhelion’s fuels to market.

September 2022

Synhelion starts construction of DAWN – the world’s first industrial demonstration plant to produce solar fuels using solar heat.

August 2022

Synhelion is the first company in the world to succeed in producing syngas on an industrial scale using only solar heat as energy source.

March 2022

SWISS is going to be the world’s first airline to use Synhelion solar fuel.

February 2022

Synhelion and Cemex produce the world’s first solar cement.

November 2021

Synhelion successfully closes its CHF 16 million Series B funding round.

October 2021

Switzerland’s largest automobile importer AMAG Group makes its first investment in Synhelion with its climate and innovation fund.
