Our Story
Admira DHES Inc. was founded as a specialized engineering consultancy focused on emerging clean energy technologies. Initially working on solar thermal projects, we’ve evolved to become leaders in hydrogen systems, cryogenic technologies, and industrial decarbonization.
Based in Ontario, Canada, we serve clients across North America and globally, bringing specialized expertise to complex energy transition challenges.
Our Approach
We believe successful energy transitions require both technical excellence and practical implementation strategies. Our work is guided by three principles:
- Integration over isolation: We design solutions that work within existing infrastructure while enabling future technologies
- Safety as foundation: Our deep experience in HAZOP/FMEA and process safety informs every project
- Scale-appropriate solutions: We focus on right-sized technologies that deliver meaningful impact for our clients
