SkiesFifty

SkiesFifty is an investment and advisory firm focused on accelerating sustainable aviation. Its stated aim is funding the journey to carbon-neutral skies by 2050. The company says its team of over 30 combines aviation, sustainability, energy, chemical engineering and investment expertise. It describes itself as a commercial investor that pursues financial returns with purpose.

The company says sustainability is becoming the aviation industry's number one issue. Aviation accounts for about 2.5 percent of global emissions, or 4 to 6 percent including non-CO2 effects. The industry has committed to net carbon neutrality by 2050. Under business-as-usual scenarios, aviation emissions are set to rise by 2 percent a year. SkiesFifty argues that more investment and collaboration are urgently needed.

The firm notes that Sustainable Aviation Fuel costs between two and five times as much as regular jet fuel, and makes up only 0.1 percent of current fuel volumes. It says only 25 to 40 percent of emissions can be cut through efficiency gains. The remaining 60 to 75 percent need investment in new technology and commercialization.

SkiesFifty invests across venture capital, private equity, public markets and infrastructure. It backs breakthrough technologies and scalable solutions. Its expertise covers sustainable aviation fuel, carbon removal, advanced propulsion and autonomous operations.

The portfolio includes HiiROC, Hydrobe, Firefly, Frontline Bioenergy, Gigablue and Catalsys. Strategic partners listed are ICAO, IATA, Boeing, Amadeus, the SAF Coalition, Project Sky Power and the Sustainable Aviation Future congress.

Recent news includes an advisory and development partnership with Stratus Energy Partners to accelerate decarbonization of aviation. SkiesFifty has also signed a collaboration agreement with TNO, the Dutch independent applied research organization, to strengthen the technical basis of its SAF investment decisions. The firm publishes articles from its people on SAF investment and on lessons from Asia's approach to innovation. The partner team includes former airline and consulting executives.
