United Grows Its Electric Battery Portfolio with Investment in EPS


Electric Power Systems (EPS) modules are technology that could be compatible with and used in support of United's future decarbonizing investments

United is targeting EPS modules for potential use in airline's current ground operations, while eyeing an all-electric flight academy in the future

United today announced an investment in Electric Power Systems, a company producing battery technology that can potentially be used for a broad suite of aerospace applications. Rather than producing battery cells, the company's compatible module technology can be adapted to support a variety of batteries, optimizing performance and safety. The versatility of the technology could allow United to consider EPS's modules for a number of near-term applications, and as part of its longer-term operations that support decarbonization. This is United's second investment in electric battery technology, after sodium-ion battery-maker Natron.

“Typically, we've had a clear vision of how to integrate sustainability investments into our operations. What makes EPS's technology different and exciting is the scope of operational possibilities where we have the option to deploy it today and, in the future, to help electrify and decarbonize our operations,” said United Airlines Ventures President Michael Leskinen. “United's best roadmap to reaching net zero carbon emissions by 2050, without relying on traditional carbon offsets, is by using every tool at our disposal – that includes the potential use of EPS's impressive portfolio of electric aircraft powertrain solutions, including high-performance power electronics, and energy storage systems.”

Electric Power Systems aims to provide a whole battery “ecosystem” for aviation, from the packs on aircraft to charging stations on the ground. This in turn is designed to keep costs low and provide rapid charges without degrading the life of the battery. Key to the entire proposition of electric aviation is designing a battery that can store a high amount of energy with as little weight as possible. If a battery is too heavy, it makes an aircraft uneconomic compared to conventional fossil fuel-powered planes.

“We are excited to collaborate with United Airlines Ventures as we continue to advance electric aviation technology,” said Nathan Millecam, CEO of Electric Power Systems. “United's investment will enable us to scale our operations and expedite the development of our cutting-edge powertrain solutions. By working together, our aim is to revolutionize air travel and build a more sustainable future for the industry.”

United is exploring options to move its pilot training academy, Aviate®, away from internal combustion-powered training aircraft to electric ones. EPS's powertrain could serve as the core propulsion system for a family of future electric aircraft concepts, starting with an electric trainer and scaling to larger variants as technology advances.

Additionally, United has more than 12,000 pieces of motorized ground equipment across its operations, of which about one third are currently electric. EPS's battery modules could potentially be deployed in support of several uses, including:

  • Charging electric ground equipment
  • Charging anticipated future electric aircraft such as electric air taxis
  • Electrified auxiliary power unit (APU) start products
  • Electrified cold-chain storage product for cargo containers

United's Commitment to Net Zero Emissions by 2050United aims to be 100% green by reducing its GHG emissions 100% by 2050, without relying on traditional carbon offsets. In addition to the UAV Sustainable Flight FundSM, United has launched a SAF purchasing program called the Eco-Skies Alliance and established a venture fund – United Airlines VenturesSM – to identify and invest in companies and technologies that can decarbonize air travel. These strategic investments include carbon capture, hydrogen-electric engineselectric regional aircraft and airtaxis. In May 2023, United received validation of our 2035 near-term emissions reduction target from the Science-Based Targets Initiative (SBTi) to reduce our carbon intensity 50% by 2035 from a 2019 base year. This year, United became the first U.S. airline to show customers an estimate of each flight's carbon footprint in their search.
