About Synhelion and our technology

Synhelion is a clean energy company that has developed a unique technology to produce sustainable solar fuels from solar energy. Synhelion contributes to a net-zero transportation sector by replacing fossil fuels with carbon-neutral solar fuels. Our solar fuels close the carbon cycle and drive a world connected by clean, sustainable transportation.

More about us

The transportation industry emits 8 billion tons of CO2 per year. We work to get this number to zero.

Solar fuels

Our solar fuels are sustainable fuels produced from solar energy. They are fully compatible with existing global fuel infrastructure and can directly replace fossil fuels. Solar fuels are carbon-neutral as they will only emit as much CO2 as was captured in their production.

Solar fuel plants

We are currently building the world’s first industrial solar fuel plant in Germany. By 2025, we aim to commission our first commercial solar fuel plant in Spain. The subsequent global roll-out of our technology will contribute to improved global energy security and independence from fossil fuel sources.

Our technology

Synhelion uses solar heat to convert CO2 into solar fuels. Our solutions combine state-of-the-art solar tower systems with proprietary high-temperature thermochemical processes. Self-contained plants that operate independently from electrical grid infrastructure make our technology quickly and broadly scalable worldwide.

Solar heat

Solar energy is the cheapest and most abundant renewable energy resource. We are the first company to sustainably generate process heat beyond 1’500°C with concentrated solar radiation. This makes it possible to drive industrial processes such as fuel production and cement manufacturing with solar heat for the first time.

Our story

Reducing CO2 emissions is the greatest challenge of our time. We contribute to a net-zero transportation sector by replacing fossil fuels with carbon-neutral solar fuels. It all started with a crazy idea at ETH Zurich. What if we could reverse combustion? Currently, we are building the world’s first industrial solar fuel production plant, taking us closer to a world connected by clean and sustainable transportation.
