Swedish car-battery maker Northvolt is expanding into aviation, as it targets the nascent field of decarbonizing commercial flight.
Lower-weight, higher-density lithium metal batteries developed by Northvolt’s Cuberg subsidiary improve upon lithium ion, which is suitable only for test flights and demonstrations, said Richard Wang, the California unit’s chief executive officer.
Cuberg has signed up several major customers for both ground testing and flight testing, and hopes to announce some in the next quarter, Wang said in an interview. The company aims to tackle emerging markets for fixed-wing electric planes, hybrids and electric vertical takeoff and landing aircraft, or eVTOLs.
Cuberg was already working on aviation battery systems when it was acquired by Northvolt two years ago. The deal gave the startup access to its Swedish parent’s experience with battery systems and packs, opening opportunities in a developing market for electric-powered air travel that could reach tens of billions of dollars by 2030, Wang said.
“Between our battery cell and battery systems people, we probably have perhaps the largest and best resourced aviation battery strategy in the world,” Wang said.
While lithium-ion batteries have pushed the range of all-electric passenger cars beyond 300 miles, they’re too heavy for all but the smallest of aircraft, limiting their commercial use. Even the smallest passenger jetliners are out of reach for battery propulsion. European planemaker Airbus SE is betting on hydrogen as an alternative to fossil-derived jet fuel. Read More…
