Horizon Energy Systems is headquartered in Singapore, where its group of scientists and engineers dedicate their advanced power systems R&D to aerospace & defence products and clients. The company's innovations are recognized as best-in-class for the purpose of powering all-electric Unmanned Aerial Vehicles (UAV). and has successfully collaborated with many renowned UAV manufacturers. Horizon was one of the first in the world (2005) to demonstrate fuel cells as a power source for flight. Since then, the company has accumulated extensive flight mileage and have been tested on different platforms. This valuable experience coupled with cutting-edge fuel cell technology, give Horizon a significant advantage when designing optimal power systems for such all-electric UAVs. Today, Horizon is proud to introduce the AEROPAKTM - a power system that greatly enhances the possibilities for today's and tomorrow's UAVs. Background Horizon Energy Systems is a subsidiary of Horizon Fuel Cell Technologies; the latter was founded in 2003 to introduce commercially viable, clean hydrogen fuel cell powered products in various markets including consumer and industrial segments. Thinking big yet starting small, the company focuses on turning fuel cell technologies into products. To date, Horizon has successfully launched over 20 innovative fuel cell products in the consumer markets and targets applications in consumer electronics, portable emergency power, stationary back-up power and clean transportation industries. Horizon Energy Systems was established in 2009 as a separate subsidiary dedicated to Aerospace and Defense markets. Its purpose is to serve increasing demand for high performance power systems for demanding applications such as UAV. Horizon Energy Systems specializes in providing fuel cell and integrated hydrogen generation systems for UAS: prolonging flight time, reducing operational costs and casualties, and facilitating new mission frontiers.
