CO2 is an immense environmental problem today. As we seek specific countermeasures against climate change, reducing CO2 is mission-critical. To achieve a carbon-free society, large-scale implementation of renewable energy and hydrogen solutions are in demand, calling for practical systems and infrastructure.

Composite tanks will be a game-changer in this energy shiftーfor safe, efficient storage and transportation, as important as the manufacturing of clean energy itself.

Space Walker is developing a winged reusable rocket mobilized by carbon-neutral liquefied biomethane propellant.

In rocket development, tanks are a key component that have a significant impact on the overall weight. Strict requirements must be cleared―such as lightweighting of the tank, storage efficiency, pressure resistance, strength, not to mention safety standards.

Under these conditions, Space Walker is developing a linerless cryogenic liquid composite tank, aiming for further weight reduction in contrast to conventional composite tanks with liners.

We are also developing ultra high-pressure gas composite Type IV tanks with plastic liners and resin-impregnated carbon fiber winding. These products will be used here on Earth; in cylinder bundles for hydrogen trailers and other transfer equipment, composite tanks for hydrogen stations, and for use in fuel cell drones and other applications.

Born from space rocket development, Space Walker tanks will contribute not only to the future of space but also here on earth. With products that store and transport hydrogen as well as other clean fuel and energy transitions, we will contribute to low-carbon mobility and the realization of a decarbonized society.
