The clean alternative to fossil fuels

Sustainable fuels made of solar energy

Solar fuels are synthetic fuels produced from solar energy. They are the most economically viable, efficient, scalable, and environmentally friendly solution for clean, long-distance transportation. A cutting-edge technology that offers a sustainable alternative to fossil fuels.

Why solar fuels?

Compatible.

Solar fuels are chemically akin to fossil fuels. They are fully compatible with the global fuel infrastructure. There is no need to adapt or refit combustion engines, refineries, fuel distribution, or filling stations.

Affordable

Affordable.

Solar fuels are an economically viable substitute for fossil fuels. Our technology is affordable thanks to a much higher energy conversion efficiency than other synthetic fuel technologies.

Versatile.

Jet fuel for planes, gasoline for cars, marine fuel for ships, and diesel for trucks – Synhelion technology yields any type of fuel. Solar fuels can replace fossil fuels in all application areas.

Scalable

Scalable.

Solar fuels are scalable to cover global fuel demand. Thanks to the grid-independent setup of our plants, the technology can scale quickly and independently.

Eco-friendly

Eco-friendly.

The entire life cycle of solar fuels is based on environmentally-friendly principles. The fuels are produced with renewable energy and emit not only less CO2 but also less noxious gases than conventional fuels.

Storable

Storable.

Liquid fuels have a very high energy density. They can be transported and stored for a long time without compromising their quality. A winning combination of two non-negotiables for many fuel-consuming industries.

Independent

Independent.

Ideal conditions to produce solar fuels can be found on any continent. The independence from fossil resources results in greater autonomy. Shorter transportation routes are another key asset.

Carbon-neutral

Circular.

Our solar fuels close the fuel carbon cycle. They only release as much CO2 into the atmosphere as was used for their production.

Solar fuels for the transportation sector

Synhelion can produce any type of carbon-neutral solar fuel: kerosene, gasoline, diesel, methanol, hydrogen, synthetic crude oil, and many more. Our sustainable fuels are compatible with conventional aircraft, ships, trucks, and cars.

Our focus is on decarbonizing those transportation sectors, that are difficult to electrify, such as aviation and shipping. In road transport, electrification plays a key role in reducing CO2-emissions. However, studies show that there will be many remaining internal combustion engine vehicles around the world that will also need to be powered sustainably to meet net-zero emission targets by 2050. As a complementary solution to road electrification, Synhelion’s solar fuels can help achieve these targets.

FAQ

Below you will find answers to the questions we are most frequently asked by our community.

  • What types of solar fuels can you produce?

    We can produce any type of solar fuel: kerosene, gasoline, diesel, methanol, hydrogen, synthetic crude oil, and many more. This is possible because we produce hydrocarbon chains – and simply put, fuels are nothing else but hydrocarbon chains of different lengths.

  • Do solar fuels require special combustion engines?

    No, solar fuels are a drop-in technology, which means that they can replace fossil fuels without any need to change the existing global fuel infrastructure. They are compatible with existing internal combustion engines and jet engines.

  • How much will your solar fuels cost?

    We target a production cost below EUR 1 per liter by 2030. Our goal is to reach production costs competitive with other sustainable fuel technologies.

  • Is it really possible to reverse combustion?

    Yes, it is. When conventional fuels are burnt with oxygen, they release heat, CO2, and water vapor. Synhelion’s technology reverses this process. With the help of solar heat, we recombine water vapor and CO2 into hydrocarbon fuels.

  • Can your technology help to solve the climate crisis?

    The transportation industry accounts for approximately 25 percent – or 8 billion tons – of manmade CO2 emissions per year. CO2 is the principal greenhouse gas contributing to global warming. Replacing fossil fuels with solar fuels is therefore one of the much-needed solutions to fight climate change. However, Synhelion believes that to combat climate change and its related problems, it is important that many different, new technologies and innovations come together.

  • Is solar fuel technology scalable to cover global demand?

    Yes, because solar fuels are produced from abundant resources and the solar fields are installed on non-arable land. An independent study assessing the geographical potential concludes that solar fuels could cover 50 times the current global jet fuel demand.

  • When will this technology be ready to go on the market?

    We are currently building our first industrial plant for the production of carbon-neutral solar fuel in Jülich, Germany. Industrial solar fuel production will start in Germany in 2024, and by 2025, we plan to commission the first commercial production facility in Spain. By 2033, we plan to ramp up production capacity to produce 1 million tons of solar fuel per year, enough to cover about half the kerosene fueled in Switzerland. By 2040, we aim to produce 40 million tons of fuel per year.

  • What markets do you focus on?

    Synhelion’s mission is to support the decarbonization of the transportation sector, especially those sectors that are difficult to electrify, such as aviation and shipping.

    In road transportation, electrification plays a key role in reducing CO2-emissions. While electromobility can be rolled out quickly in some regions of the world, such as Europe, it will take much longer in other regions to significantly reduce the number of vehicles with internal combustion engines (ICE). Studies show that there will be many remaining ICE vehicles around the world that will also need to be powered sustainably to meet net-zero emission targets by 2050. As a complementary solution to road electrification, Synhelion’s solar fuels can help achieve these targets.

  • What is new about your technology? Why hasn’t it been developed before?

    Thermochemical production of solar fuels requires extremely high process temperatures. We solved key challenges in the transformation of solar radiation into process heat and in thermal energy storage. Furthermore, we developed a unique technology to produce syngas. By combining these innovation fronts, we can achieve unprecedented efficiency.
