H55 SA is a Swiss company created in 2017 by three members of the Solar Impulse Project, the first round-the-world solar flight. With the strategy of offering electric propulsion solutions to aircraft manufacturers, with systems safety review leading to airplane certification ready, H55 has dedicated the last year and a half to the development of its EPS55 patented technology: The Electric Propulsion System for the Air Transportation of Tomorrow.

EPS55 is a ground-breaking and cost-effective Electric Propulsion System (EPS) for Very Light Aircrafts (VLA) and Vertical Take-off and Landing (VTOL) with a certifiable Battery Management System able to handle multiple battery systems, electric motors, hybrid systems and do so while setting priorities in an organized hierarchical way. EPS55 has already proven its feasibility with the integration of a first prototype in an acrobatic aircraft in 2017 which achieved performance values far ahead any of its EPS competitors: 1-hour flight time with 40% of battery reserves at a direct costs per hour of only 18€.

Electrifying aviation market is a real and urgent need to achieve noise and green-house emissions reduction of the sector, which reached 768 million tonnes of CO2 in 2016. In addition, safety is a major issue and reducing the human failure factors, which account for the largest reason of air accident fatalities among light aircrafts, is a must. Regarding costs, electrifying light aircraft industry will be market feasible only if final operational costs are approximate to other means of transport like vehicles.

Electric aircraft market has a huge potential: it is projected to grow from 6.61€ Billion in 2018 to 9.27€ Billion by 2021, at a CAGR of 7.33% and is predicted to keep growing at a CAGR over 4% after 2021. EPS55 will reach this market by 2021 and will enable the next necessary step for electric aviation to become a reality.
