About

Founded in 2023, Solidflow is a defense subsystem manufacturer based in Noordwijk, Netherlands working in soldier equipment, space.

Solidflow BV is a small enterprise based in Noordwijk, Netherlands, that develops and produces Cool Gas Generators (CGGs). These solid-propellant devices produce pure gas at ambient temperature without pressurised storage. The company's oxygen generator is being developed with the Royal Netherlands Army and the Dutch Ministry of Defence for supplying oxygen to wounded soldiers, under a contract from the National Technology Programme. Other products include carbon dioxide, hydrogen and MINOS generators for space propulsion and pressurisation, emergency power, and rescue and inflation applications. Solidflow is a spin-off of HDES Service & Engineering BV and traces its technology to TNO, which spun it out in 2011. It is part of the Space Business Innovation Center in Noordwijk and is planning a pilot production facility on the NL Space Campus. The company also has a planned joint venture in Australia with Advier Australia and Spacelink Consulting.
