An Idea Born in


H55 is proud of its Swiss heritage. Switzerland is a leading player in hydro-energy and its reputation for high value-add industries in the field of energy management technologies has and continues to be an important factor contributing to the growth of the company.

Through Switzerland’s federal engineering schools, ranked as some of the highest educational institutions in Europe, H55 actively collaborates across several research and development projects with the country’s best engineering and scientific minds. Through the support of the Canton of Valais and the City of Sion, the company also benefits from a state-of-the-art airport facilities where its technology is integrated, and flight tested.

Our facility in

As part of its international expansion plans, and in particular being able to respond to the company’s growing North American customer base, H55 has established a fully owned subsidiary in Canada, H55 Inc. Located in the greater Montreal area, H55 Inc collaborates with existing customers for development, customisation, and after sales support. A manufacturing facility will see battery pack production beginning in 2024.

Being present in a major global aerospace cluster offers many opportunities for H55 to collaborate with companies and research institutions that are part of a vibrant aviation ecosystem and who are all committed, as with H55, in demonstrating the advantages of adopting efficient and cost-effective sustainable technologies.

Located in the heart of one of Europe’s leading aviation hubs, and in close proximity to H55’s growing customer base, the Toulouse subsidiary office will serve as an important strategic base for H55’s operations. The new office includes development, testing, aircraft integration, and customer support functions. H55 France will allow H55 to strengthen its relationships with key partners, industry stakeholders, and customers both in France and across Europe, as well as serve as a key recruitment center to draw on the highly experienced local aerospace talent pool.
