Advanced CNT-based composite material for Hydrogen and CO2 transport tanks
Store your energy light & tight
CUPAH develops a new lightweight, high-performance composite material to pressure vessels for transport of hydrogen and carbon dioxide. By using carbon nanotube (CNT) reinforcement, our material reduces tank weight and energy usage, unlocking scalable & sustainable solutions for the energy transition.
Our CNT-based tank material developments are based on our revolutionary molecular technology which disperse and anchor CNT into composite materials. CNTs have up to 20 times higher specific strength than carbon fibers normally used in pressure vessels. This opens up for much lighter tanks, higher storage capacity as well reduced energy consumption transporting the gas or liquid.

CUPAH is established in 2021 by Morten G. Stage as an innovation company developing a ground breaking carbon-nanotube (CNT) based composite material designed specifically for use in Hydrogen & Carbon Dioxide Transport and Storage tanks.
Our mission
At CUPAH, our mission is to revolutionize the global transport of hydrogen and carbon dioxide through the development of ultra-lightweight, high-performance composite materials for pressure tanks. By leveraging carbon nanotube (CNT) technology, we enable safe, scalable, and energy-efficient storage solutions across both ambient and cryogenic conditions.
We aim to accelerate the decarbonization of heavy transport, industrial processes, and CCUS infrastructure by reducing the weight, cost, and emissions associated with pressurized and cryogenic gas logistics.
Dr. Morten Gjetting Stage is the founder and driving force behind CUPAH. With a PhD in physics from Chalmers University of Technology and a career in the energy sector, Morten brings deep technical expertise and leadership to CUPAH’s mission.
He has held senior roles at DONG Energy (now Ørsted), Maersk Oil, and TotalEnergies, where he led major innovation efforts in carbon capture and energy systems. He chaired the INNO-CCUS partnership and serves on several advisory boards.
In 2024, Morten chose to fully focus on CUPAH, applying his experience to commercialize CNT-reinforced composite tanks for hydrogen and CO₂ transport to eliminate inefficiencies in gas logistics and enable scalable decarbonization in mobility and industry.
Morten continues to advise start-ups, industry, research institutions, and funding bodies.

Within this framework, hydrogen has been singled out as central for addressing both issues and for evolving our energy systems.
Hydrogen storage is a key enabling technology for the advancement of hydrogen and fuel cell technologies in applications including stationary power, portable power, and transportation. Hydrogen has the highest energy per mass of any fuel; however, its low ambient temperature density results in a low energy per unit volume, therefore requiring the development of advanced storage methods that have potential for higher energy density
The main drivers of FCEV TCO reductions are equipment costs (fuel cell system and hydrogen tank outlays) and decreasing cost of hydrogen at the pump.
Going forward, hydrogen technology will become more important, alongside electric power – and not, as is often rumoured, just for utility vehicles,” said Oliver Zipse, BMW CEO. “This is another area where we are delivering: Our small series of the BMW i Hydrogen NEXT will be released next year.
