Gloyer-Taylor Laboratories (GTL) has said its composite tubing can reduce liquid hydrogen boil-off and chill-down time when transferring the energy carrier for aviation applications.
Results from a NASA SBIR (Small Business Innovation Research) programme have shown that GTL’s blended hybrid laminate (BHL) technology, designed for cryogenic tubing, can reduce the cooling time, hydrogen boil-off and the dry mass of cryogenic fluid transfer lines.
The US-headquartered firm said that up to 70% of liquid hydrogen can be lost during the transfer from one tank to another due to boil-off.
However, with the newly developed tech, an aircraft could fill its liquid hydrogen tanks in minutes and easily manage the small amount of hydrogen that is boiled off during fill operations, reducing fuel costs and increasing operational safety, the company claims.
