Founded in 2022, GaltTec is pioneering fuel cell technology to meet the growing demand for lightweight, sustainable, and highly efficient energy solutions. The company’s fuel cells are designed to significantly extend operational endurance for drones and IoT devices, making them a game-changer for industries that rely on long-lasting, portable power sources.
GaltTec already partners with leading drone manufacturers, including Skycorp Technologies, a European pioneer in hydrogen-powered drones, showcasing the real-world potential of its technology.
GaltTec’s dual-use strategy positions its fuel cells as a critical solution for both commercial and defense sectors. In 2024, the company became the first Estonian startup to join the NATO DIANA accelerator program, which supports deep-tech companies contributing to national security and defense. Additionally, GaltTec has signed a cooperation agreement with the Estonian Defence Forces to test ethanol-based fuel cells, further reinforcing the strategic importance of its technology.
