Green Hydrogen into European markets at scale: the TES Green Cycle explained

TES’ prime objective is to replace the fossil gas system by importing green gas (CH4) produced using green hydrogen generated from solar PV in the solar belt, as well as to introduce CO2 circularity. In Wilhelmshaven, TES is building Germany's first Green Energy Hub, which will enable the import of 250 TWh of green gas by 2045.
TES provides green hydrogen at scale into global markets with an innovative business model based on proven technologies to current and future hydrogen users, particularly across mobility, industrial and power sectors. In the initial years, TES will supply an optimal mix of green and clean hydrogen to offer European customers with economic “zero emission” alternative energy at scale. Clean hydrogen will help end-users transition their assets and processes over time before fully switching to green hydrogen.
