Swedish manufacturer Heart Aerospace has taken a significant step towards revolutionizing regional air travel with the unveiling of its first full-scale demonstrator for the ES-30 hybrid-electric aircraft. Built almost entirely in the company’s Gothenburg facility, the aircraft, named Heart X1, has been designed to accommodate 30 passengers and offers an electric range of 200 kilometers. For longer journeys, a hybrid-electric system extends the range to 400 kilometers, making it a promising development in the effort to decarbonize aviation.
Heart X1 marks a key milestone in the development of the ES-30 model, the company’s flagship hybrid-electric airplane. The demonstrator will initially undergo ground-based testing, covering key procedures such as charging, taxiing, and turnaround operations. According to Heart Aerospace’s CEO, Anders Forslund, this phase of testing is a crucial precursor to the demonstrator’s first anticipated fully electric flight in 2025.
Forslund highlighted the urgency of addressing carbon emissions within the aviation industry, emphasizing that innovation cycles in aerospace typically span three decades. With less than 25 years remaining to meet global decarbonization targets, rapid advancements in technology are essential. The unveiling of the Heart X1, he remarked, is a testament to the company’s dedication and vision in developing a hybrid propulsion system in under two years.
The ES-30’s innovative propulsion system is expected to play a pivotal role in the broader push for sustainable aviation, a sector that has seen increasing demand for cleaner technologies. Heart Aerospace’s work is supported by grants from Sweden’s innovation agency, Vinnova, and the Federal Aviation Administration’s (FAA) FAST program, which awarded the company $4.1 million to help accelerate the development of its hybrid-electric propulsion management system.
As part of its future roadmap, the company will analyze data from the Heart X1 to inform the design and production of its next iteration, Heart X2. Scheduled for a 2026 launch, this pre-production prototype will be equipped with enhanced capabilities to conduct a hybrid-electric flight, further solidifying Heart Aerospace’s leadership in the green aviation space.
The company is not working alone in its pursuit of sustainable aviation. It has secured key partnerships, including agreements with Air Canada and Scandinavian Airlines (SAS), both of which have already placed substantial orders for the ES-30 aircraft. These partnerships underscore the growing interest among global airlines in adopting low-emission technologies, particularly for regional routes where short-haul flights are most common.
While full commercial certification for the ES-30 is projected to be achieved by 2030, industry experts note that the hybrid-electric aircraft is poised to transform the regional aviation market. The aircraft’s blend of electric and hybrid propulsion, combined with its short-haul capabilities, positions it as an attractive solution for carriers seeking to reduce their environmental impact while maintaining efficient operations.
