Heart’s New Hybrid-Electric Plane Could Be in the Skies by 2028

Heart Aerospace is almost ready for takeoff.

The Swedish outfit is set to launch its hybrid-electric airplane in 2028, after reaching several significant milestones in the past few months.

First unveiled in 2022, the ES-30 is designed to make regional travel cleaner and more efficient. (Nine other companies have developed concepts to do the same.) The hybrid can run on either lithium-ion batteries or sustainable aviation fuel (SAF), meaning it will produce fewer emissions than traditional aircraft. It will also be cheaper to operate than conventional competitors, according to Heart.

Powered by four electric motors, the ES-30 can fly 124 miles in emissions-free “electric mode” or 249 miles in “hybrid mode” with the help of two turbo generators. The reserve-hybrid system means that the generators only kick in when additional grunt is needed on longer routes. The ES-30 will also be quieter than gas-powered craft and can take off from runways as short as 3,609 feet.

The ES-30 will offer all the usual creature comforts, too. The spacious cabin features three-abreast seating that can accommodate up to 30 fliers. (Having 25 passengers aboard increases the hybrid range to 497 miles.) The interior also features a galley, a lavatory, and large overhead bins to ensure a comfortable in-flight experience.

Heart has a rather aggressive timeline, but is making solid progress. The company opened a new research and development hub in the United States in May to speed up the development of the ES-30. The team plans to test the propulsion system on a full-scale demonstrator and showcase fully electric flight in 2025. It will then pursue type certification in 2028.

Heart has a decent amount of backing, too. It has already raised $145 million in development funding from significant industry players like United Airlines, Air Canada, and Saab.

“Heart Aerospace has just entered an exciting new phase of hardware testing, and our aim is to have a hybrid-electric passenger plane on the market before the end of this decade;” Heart Aerospace CEO and cofounder Anders Forslund said in a statement. “As we get closer to this goal, collaborations with airports, operators, and regional authorities are crucial to ensure the eco-system needed to support electric aviation.

Heart has secured 250 orders for the ES-30, with purchase rights for another 120 planes. It has also received letters of intent for a further 191 aircraft.
