At the Hydrogen Tech Europe 2024 event, Swedish startup Graphmatech has unveiled its new range of graphene and polyamide composites , known as AROS Polyamide-Graphene, designed for hydrogen storage and transport applications. This innovative material, backed by a SEK 10 million grant from the Swedish Energy Agency, promises to transform the way hydrogen is handled, reducing leaks by up to 83% compared to traditional methods .
Graphene, with its unique strength and conductivity properties, is at the core of Graphmatech’s technology, which improves the polyamide used in Type IV Composite Pressure Vessels (CPV), significantly reducing hydrogen permeability.
This technology is strategically positioned in the market, just when the demand for hydrogen, according to McKinsey & Company, is projected to increase significantly until 2050, which requires advanced infrastructure and sustainable solutions to mitigate the environmental impact of hydrogen in case of leaks.
Graphmatech redefines hydrogen with graphene composites
Graphmatech has distinguished itself by solving a problem that has limited the industrial use of graphene: the agglomeration of particles when produced on a large scale . The new AROS polyamide-graphene composites have eliminated this barrier, increasing the strength and flexibility of the material and improving the competitiveness of polyamide against metallic materials. This innovation allows for thinner and stronger designs in CPVs, while maintaining high safety margins and reducing the carbon footprint .
The AROS Polyamide-Graphene range includes products such as Polyamide-6 and Polyamide-11, each with specific benefits: AROS PA6 , for example, has demonstrated an 83% reduction in hydrogen leakage and an increase in strength of up to 98%, while AROS PA11 exhibits an additional 160% elongation before breaking, increasing its impact absorbing ability.
This initiative by Graphmatech represents a key step in sustainable development and also underlines its commitment to the future of the hydrogen economy. With applications planned in hundreds of thousands of vehicles by 2032, the company is ready to play a key role in the global energy transition, offering solutions that improve safety and efficiency in the use of hydrogen .
