World’s largest fully battery-powered plane, X1, completes maiden flight; 30-seat hybrid-electric plane used $5 worth of electricity and other details
X1, the world’s largest fully battery-powered jet has managed to successfully complete its maiden flight in upstate New York. According to a report by Popular Science, built by Los Angeles-based Heart Aerospace, the aircraft consists of 30-seats and it flew for 27 minutes at an altitude of 1,100 feet. The interesting part about the flight is that it was completely powered by batteries. With a wingspan of 106 feet and weighing over 25,000 pounds, the X1 represents a significant milestone in electric aviation. The test flight consisted of only the pilot and there was no passenger present on the plane. Heart Aerospace, the company behind the test revealed that X1 consumed electricity of worth $5 during the entire flight. This underscores the potential cost savings of electric aviation. However, the $5 figure only reflects raw energy costs and exclude other expenses such as crew, airport fees, maintenance, and battery degradation.Along with this, the company also claims that its upcoming hybrid-electric model, the ES-30, could be 40% cheaper to operate than conventional regional aircraft, thanks to reduced fuel and maintenance costs.
The flight: 27 minutes on battery power alone
X1, the electric aircraft is built by a Los Angeles-based company Heart Aerospace. The aircraft spans 106 feet from wingtip to wingtip and stretches 76 feet from nose to tail. The flight weighs more than 25,000 pounds. It comes with seating arrangement for 30 passengers. During the test flight, the plan took off from a regional airport in New York earlier this week and flew for around 27 minutes on battery power. During the flight it claimed the altitude of 1,100 feet. Heart Aerospace founder and CEO Anders Forslund said the flight showed that electric propulsion can now operate at the scale of a commercial airliner, calling it proof of concept for the technology at that size.
From test flight to commercial ambition
The X1 flight serves as an early proving ground for Heart’s real commercial target: a hybrid-electric aircraft called the ES-30, which the company hopes to bring into passenger service by 2031. That aircraft has already drawn interest from major carriers, including United, Air Canada, and JSX, who are reportedly attracted by the prospect of lower maintenance costs and less exposure to volatile jet fuel prices.Heart Aerospace was originally founded in Gothenburg, Sweden, before officially relocating its headquarters to Los Angeles in April 2025 as part of its push to get the regional hybrid-electric plane certified and flying commercially.
Why it matters: Emissions and economics
It is important to note that electric aviation consists two potential selling points. The first and foremost is environmental: aviation is estimated to account for roughly 2.5 percent of global carbon dioxide emissions, and planes also emit other heat-trapping pollutants like nitrogen oxides. The industry has set a goal of reaching carbon neutrality by 2050, a target widely seen as unlikely to be met even with advances in sustainable fuel. Electric aircraft, particularly those charged using renewable electricity, could help chip away at that footprint, though not transform the industry outright any time soon.The bigger draw for airlines, though, is cost. Jet fuel prices have been volatile, averaging $3.50 per gallon in the week before the test flight — up 63 percent from a year earlier. Electric motors also have fewer moving parts than jet engines, which in theory means lower maintenance costs, an argument automakers have made for years in pushing electric vehicles. Heart claims that reduced fuel and maintenance costs combined could make its future ES-30 as much as 40 percent cheaper to operate than similarly sized conventional regional aircraft.
The $5 flight
Heart also touted a headline-grabbing statistic: the X1’s test flight reportedly used just $5 worth of electricity. The figure is eye-catching, but it only reflects raw energy costs. It excludes other major operating expenses such as crew, airport fees, routine maintenance, long-term battery degradation, and insurance. Whether airlines would see meaningful net savings from switching to hybrid-electric aircraft — and whether any of those savings would ever reach passengers through lower fares — remains unclear.Forslund argued that electric commercial aircraft could eventually reshape airline economics broadly and help lower the overall cost of air travel, though that outcome is still speculative at this stage.
Future of hybrid-electric aviation
While the X1 demonstrates the feasibility of large-scale electric flight, its range is limited to about 125 miles. Heart’s hybrid-electric ES-30, expected to enter service by 2031, extends that range to 500 miles with a combustion engine range-extender. Airlines including United, Air Canada, and JSX have already expressed interest. Heart Aerospace CEO Anders Forslund said, “Electric commercial aircraft have the potential to fundamentally reshape airline economics and, ultimately, lower the cost of air travel for passengers.”
