CST Optimum enables the rapid uptake of green hydrogen in Australia, the USA, and globally, by providing safe, light, cost-effective, pressure vessels.
Using green hydrogen as a fuel reduces carbon emissions from key industries such as transportation, and those that cannot be easily electrified, including steel and cement production and aerospace.
