The hydrogen from the planned cooperation should be produced from natural gas with the help of carbon capture and storage (CCS).
RWE can then deliver this to its customers in Germany and in the rest of Europe.
The basic agreement also provides for closer cooperation between companies in the liquefied natural gas (LNG) business.
Climate-friendly hydrogen plays a key role in the energy transition, as it can be used to replace climate-damaging carbon dioxide.
The aim is the production of hydrogen from renewable energies, so-called green hydrogen.
Since the required amount cannot initially cover the demand, blue hydrogen could be produced temporarily.
The CCS method ensures a reduction in CO2 emissions.
The safeguarding of the fluctuating green electricity generation could be done by gas-fired power plants, which also use green hydrogen for production.
"But until that happens, interim solutions such as gas, LNG and blue hydrogen will be needed," said Javier Moret, head of RWE Supply & Trading's LNG business.
