The University of Bath and sensor manufacturer Druck are developing the world's first flight-certified cryogenic hydrogen pressure sensor through a Knowledge Transfer Partnership (KTP). 

While liquid hydrogen (LH₂) is a leading clean fuel alternative, it must be stored at extreme cryogenic temperatures that exceed the limits of current aerospace sensors. Using the University of Bath's IAAPS institute, a facility specialized in net-zero and cryogenic infrastructure, the team will design sensors capable of monitoring LH₂ systems to ensure safety, detect leaks, and optimize efficiency in flight.

Carl Sangan, Professor of Sustainable Propulsion and Power at the University of Bath, noted:

"This is an extremely exciting KTP, giving us the opportunity to support the aerospace industry in delivering net-zero travel. We look forward to collaborating with Druck to develop flight-qualified cryogenic hydrogen pressure sensors."

Druck already maintains over 500,000 sensors in operation, but this partnership pushes into a new technological frontier. As Druck's President, Gordon Docherty, stated:

"If successful, this innovation will represent one of the most significant breakthroughs in harsh environment pressure measurement technology this century. We're excited to work with the University of Bath and help make hydrogen-powered flight a reality."

Funded by Innovate UK, this KTP merges academic research with industrial expertise to bring hydrogen-powered flight one step closer to the runway.
