Uppsala, Sweden — The companies will develop and produce a new high performance type IV pressure vessel liner. Expected improvements include reduced hydrogen leakage and increased resistance to extreme thermal- and pressure conditions.

The partnership combines Steelhead Composites’ leading pressure vessel technology, services, and market position with Graphmatech’s graphene-polymer composites for the hydrogen economy.

Graphmatech’s patent-pending technology mixes graphene flakes in the polymer matrix evenly, preserving much of graphene’s amazing material properties. In comparison to competing materials, the resulting graphene-polymer composites are, among other things, less permeable to gas, more electrically conductive, more thermally conductive, and easier to process in a wide range of manufacturing technologies.

“Partnering with Steelhead Composites is a big step forward in our mission to enable the green transition with graphene. We’re eager to develop and launch this graphene enhanced hydrogen pressure vessel liner together,” says Dr Mamoun Taher – CEO & Founder of Graphmatech.

“As we strive to manufacture and deliver the best hydrogen storage solutions across the globe, we are thrilled to embrace innovative technologies like Graphmatech’s graphene-polymer composites,” says Andrew Coors, CEO of Steelhead Composites.

Safer, less leaky gas tubes to Canada 

Uppsala, Sweden — According to their new MoU, Polytubes and Graphmatech are co-developing tubes for hydrogen and gas distribution.  The pipes are expected to leak significantly less hydrogen gas than current technology. Reducing leakage is not only a financial priority, but also an environmental priority. Hydrogen has a an eleven-times higher global warming potential (GWP)

Reducing hydrogen gas leakage from pipes and storage vessels by more than 40% using graphene

Uppsala, Sweden — Hydrogen is a key part of the transition to a sustainable future, but it poses engineering challenges; the gas molecules are very small, easily escaping through different types of materials. In addition, Hydrogen gas is stored at extreme pressure- and temperature conditions.The materials currently used in Type IV pressure vessels and pipes

A breakthrough in battery recycling helps enable the green transition

Graphmatech, Graphenea, and Northvolt have succeeded in up-cycling end-of-life EV batteries into graphene oxide at industrial pilot scale. This breakthrough uses the material left after Northvolt has extracted valuable metals and minerals. Until now, that remaining material has been waste.   Emma Nehrenheim, Chief Environmental Officer of Northvolt, comments: “The upcycling of graphene oxide from recycled
