Hydrogen fuel in aerospace could cut down on the vast amounts of CO2 produced in air travel and shows. Balanced systems and initiatives will help promote hydrogen fueling, but the push to decarbonize air travel is difficult and costly. By Aadya Karthik

Condensation trails, the vapor trails left behind planes, account for 35% of aviation's total global warming impact. Smarter architecture of flight paths and plane choices could dramatically reduce this effect. By Lakshanya Rajesh

With battery limitations slowing the path to fully electric aviation, hybrid-electric systems are emerging as a practical alternative. Combining conventional engines with electric propulsion can cut emissions, improve efficiency, and provide a scalable transition toward sustainable flight. By Heer Patel

Fuel efficiency in commercial aircraft when cruising is far worse than any other state due to wing shape optimization. Active aerodynamics designed for takeoff, landing, turbulence, and much more could help increase fuel efficiency and bolster performance.

Excess carbon emission is one of the biggest challenges in the world of aerospace sustainability. This article explores the potential role of sustainable aviation fuel and alternative rocket fuels in decarbonizing the aerospace industry. 

The majority of commercial aircraft parts are made from recyclable materials. Decommissioned aircraft could serve as building blocks for future planes, but safety regulations and industry standards make recycling every piece of an aircraft unfeasible.

Despite high upfront costs, sustainable aviation fuels offer long-term strategic value to the U.S. military: reducing dependence on foreign oil, stabilizing energy access during geopolitical crises, and potentially cutting future fuel costs. In this EcoAero article, Aviraj Dastidar weighs the case for green investment in defense aviation.

Arkisys is building modular spaceports designed for long-term servicing and refueling tha will push satellite infrastructure beyond one-and-done missions. With robotics, standard interfaces, and a “Cutter” vehicle for last-mile delivery, CEO David Barnhart envisions a future where space platforms grow, adapt, and generate recurring revenue.
