Ultralight and sustainable hydrogen tanks

Important results from the project

The goals have been met: Two prototypes have been manufactured and have also been shown at a conference in Poland. Contact with new possible financing has begun here. The two different manufacturing methods can be assumed to be similar in actual manufacturing, although dry-wound in our case took longer time due to the fact that it is a completely new manufacturing method for us. The dry-wound prototypes are much better from a recycling perspective because they can be wound up into long fibers.

Expected long term effects

SSAC has taken another step towards being able to commercialize hydrogen tanks. New collaborations have begun where the knowledge from this project is very important. New project at the EU level has also been sought, which would cause further networks and kunksap to emerge.

Approach and implementation

The arrangement has worked well and with good cooperation within the consortium. Two prototypes were designed where one focused on durability (dry-wound hydrogen tank). Both were designed to meet the requirements specification that SSAC had. The test printing showed that some things need to be improved where the problem was not the fiber-lined tank itself, but more on connections and gluing with the liner needed - which is therefore a commercial product and was not manufactured in the project.
