First test flight of largest all-electric aircraft used just $5 of electricity
Summary
Heart Aerospace flew the largest battery-electric aircraft, the X1, for nearly 30 minutes using only $5 worth of electricity. This test is part of developing a hybrid-electric regional airliner, the ES-30, which combines electric motors with traditional engines to reduce fuel use and emissions.Key Facts
- The X1 is the largest all-electric aircraft to fly, with a max takeoff weight over 25,000 pounds.
- It flew at Plattsburgh International Airport on August 12, powered by four electric motors and batteries delivering over one megawatt.
- The flight lasted nearly half an hour and cost about $5 in electricity.
- Current battery technology limits purely electric planes to short flights of 100 to 200 miles, restricting them to air taxi roles.
- Heart Aerospace plans to produce the ES-30, a hybrid-electric plane that can fly 125 miles on electric power alone and 500 miles in hybrid mode combining electric and turboprop engines.
- United Airlines has agreed to buy 100 ES-30 planes, with other airlines also investing in the project.
- The ES-30 aims for flight testing in 2028 and commercial certification by 2031.
- Rising jet fuel prices, linked to geopolitical tensions such as the US-Israeli war on Iran, are pushing the airline industry to explore cleaner and more cost-effective aircraft options like hybrid-electric planes.
