The aviation industry faces increasing pressure to reduce its environmental impact, particularly regarding carbon emissions and noise pollution. Traditional aircraft propulsion systems contribute significantly to these issues, necessitating the development of more sustainable alternatives.
Ascendance develops hybrid-electric propulsion systems for aircraft, offering a pathway to significantly reduce CO2 emissions and noise pollution compared to conventional aircraft. Their Sterna technology can be integrated into new aircraft designs or retrofitted into existing models. Ascendance's hybrid-electric approach combines electric motors with traditional combustion engines, optimizing fuel efficiency and reducing reliance on fossil fuels. The company's Atea aircraft, powered by Sterna, demonstrates the potential for substantial emissions reductions in passenger transport, medical services, and cargo operations. By leveraging hybrid-electric technology, Ascendance aims to drive the aviation industry towards carbon neutrality and more sustainable air travel.
Ascendance's primary customers include aircraft manufacturers, airlines, cargo operators, and medical transport providers seeking to reduce their environmental footprint and operating costs.
