Introduction to Hydrogen Energy Technology

Rayvatek’s carbon fiber winding technology enables the production of robust storage tanks, achieving a container pressure of 700 bar. We have completed relevant certifications and testing, ensuring that this storage tank technology can safely store hydrogen, even exceeding average standards.

The use of hydrogen is becoming increasingly popular. It is produced by electrolyzing water using green electricity and then stored in carbon fiber-wound bottles, before being converted for use in fuel cells. We anticipate the scope of hydrogen use, both concrete and projected, to continue expanding.

Beyond simply providing hydrogen bottle storage tanks for streamlined energy storage or industrial and transportation applications, Rayvatek currently offers customized development for different materials other than hydrogen. For instance, our fluid storage tanks are now being utilized by clients as storage containers for the oxidizers required by small carrier rockets.
