Commercially-viable Hydrogen Aircraft for Reduction of Greenhouse Emissions
U.S. Aviation Climate Action Plan has set Sustainable Aviation Net-Zero Carbon Emissions Goals by 2050
• Europe established a strategy in 2020 and is engaging with industry for hydrogen-fueled aviation
– A Hydrogen (H2) Strategy for a Climate-Neutral
Europe
– Sustainable & Smart Mobility Strategy
• The U.S. National Clean Hydrogen Strategy and
Roadmap presents a strategic framework for
achieving large-scale production and use of clean
hydrogen
• SAF reduces emissions and fossil fuel dependency,
but transition to new approach required to achieve 2050 goals beyond SFNP (AACES 2050 study)
• Switch to renewable cryogenic fuels to eliminate carbon emissions from fuel production and aircraft
propulsion (assuming sustainable fuel sources are available)
SAF = Sustainable Aviation Fuel; SFNP = Sustainable Flight National Partnership; AACES = Advanced Aircraft Concepts for Environmental Sustainability
