SSET has been planning, distributing, investing industry chain of clean energy, actively constructing comprehensive energy station of oil, gas, hydrogen, PV, electricity and LNG plant. We have mature technology of preparation, transportation, fueling for the LNG application. We can prepare, store, fuel H2, and have the manufacturing and applying ability of hydrogen industry chain downstream application. We have various methods to product hydrogen by water electrolysis, petrochemical resources, chemical materials, tail-gas from chemical plant. Depend on technology of cryogenic and air separation, we research and improve technology of hydrogen production which is more efficient and lower cost, and research safe and reliable hydrogen storage, fueling plant.
