Synhelion: Turning Sunlight into Jet Fuel

The Swiss deep-tech startup turning solar heat into liquid fuel for net-zero aviation

While others install solar panels for electricity, Synhelion is using concentrated solar heat to crack water and CO₂ into synthetic hydrocarbons. This isn't a carbon capture pipe dream—it's a working industrial process.

""We're not just generating electricity from the sun—we're storing solar energy in liquid form, creating a battery that powers existing engines.""

The Technology Play

Synhelion's core innovation is a thermochemical process that uses concentrated solar radiation to reach temperatures exceeding 1,500°C. At these temperatures, they split CO₂ and water into CO and H₂—synthetic gas that can be refined into diesel, jet fuel, or gasoline. Unlike biofuels, this requires no agricultural land, no food crops, and produces zero net emissions when the fuel burns.

The Market Timing

With the EU's SAF blending mandate requiring 2% sustainable aviation fuel by 2025 and 70% by 2050, Synhelion is perfectly positioned. Their keyword data shows searches for 'eu saf blending mandate' (230 monthly volume) and 'saf mandate' (250 monthly volume) drive significant traffic. This isn't just climate tech—it's compliance tech for an industry facing existential regulatory pressure.

The company's traffic reveals a sophisticated audience. With 15,051 monthly visits and 52% organic search, they're attracting aviation executives, policy makers, and sustainability officers researching mandates. The 32% direct traffic suggests strong brand recognition in a niche industry. Their social presence on YouTube, LinkedIn, and Instagram indicates they're building thought leadership, not just product demos.

  • Solar-to-fuel efficiency exceeds 20% in pilot plants—industry-leading for concentrated solar thermochemistry
  • Their 'Dawn' plant in Switzerland has produced over 1,000 liters of solar diesel, validated by third-party testing
  • Partnerships with Swiss International Air Lines and CEMEX demonstrate commercial viability beyond pilot scale
  • The 64-person team is heavily weighted toward process engineering and chemical engineering PhDs
Doesn't produce biofuels from crops or waste
Creates synthetic hydrocarbons directly from solar heat
Doesn't rely on carbon capture storage
Uses existing refinery infrastructure for final processing
Doesn't generate electricity for the grid
Produces drop-in fuels compatible with current engines

The Bottom Line

Synhelion is betting that aviation's decarbonization won't come from electric batteries or hydrogen, but from liquid fuels that work with today's infrastructure. With $40M in funding and a working pilot plant, they're either 10 years ahead of the market or 10 years too early. The SAF mandate timeline will decide.
