Great project to generate and store green energy on the form of H2. Believe as of today the project has advanced. Many challenges are on the project based on short or long term forecast. Generating 3000 TWh to 4000 TWh on 2050 and storing 1200 TWh on 2050 on green H2 will need production of 43330-5774 TWh per year electricity. During 2023 world renewable energy from wind and solar was around 3000 TWh and EU may have contributed 250 TWh solar and around 420 TWh from wind (believe these are correct). Europe must increase green energy by 6 times within 27 years and convert the green electricity on green H2. Hope this project will reach the goals, but hard to believe that these will be economical. The H2 storing on depleted gas natural reservoirs may be achieved, but this will reduce the energy efficiency to as low as 20% or less. Then what about the cost?
