new technologies are providing actionable pathways for lowering greenhouse gas emissions for aircraft travel.
The future of sustainable aviation is at our fingertips, with new technologies providing actionable pathways for lowering greenhouse gas emissions for aircraft travel. Advancements in electrification and fueling are one exciting aspect, but research at the National Renewable Energy Laboratory goes beyond power generation with a holistic approach to optimize energy use throughout the entire system design.
“NREL research aims to decrease costs, reduce component footprints, and improve vehicle performance, reliability, and efficiency,” said NREL Senior Researcher Sreekant Narumanchi. “These component designs can be incorporated into various applications—from commercial aviation to smaller takeoff and landing vehicles. In addition, our findings can help optimize next-generation aircraft, including those powered by electricity, hydrogen, or alternative fuels.
The first project, led by the General Electric Global Research Center, will design a 2-MW fully integrated all-electric aircraft powertrain and demonstrate a 350-kW lab-scale prototype to enable zero-carbon-emission narrow-body commercial aircraft with all-electric propulsion. The second project, led by Marquette University, also focuses on building high-power-density motors and power electronics for aviation.
Both projects explore a unique approach to developing electric motors and integrated electric-drive systems for hybrid-electric aircraft by reducing system weight and volume to support increased range and efficiency — all without sacrificing aircraft safety and reliability.
