Green Hydrogen Production from Ocean/Sea Renewable Energy Sources Gains Momentum

Strategic Insights -

A new study introduced a novel techno-economic framework for green hydrogen production by integrating Ocean/Sea Current Turbine (OCT) technologies with desalinated seawater electrolysis. The research, conducted by Malatya Turgut Ozal University, proposed a framework that combines geospatial location selection, optimal technology matching, and detailed cost modeling under current (2024) and future (2050) scenarios. The study identified the Kilitbahir site in the Çanakkale Strait as the most suitable location for a 2 MW pilot facility, with estimated hourly hydrogen production of 22.413 kg in 2024 and 37.137 kg by 2050.

Key Takeaways:

  • The study introduced a novel techno-economic framework for green hydrogen production by integrating OCT technologies with desalinated seawater electrolysis.
  • The proposed framework combines a geospatial location selection model, optimal technology matching, and detailed cost modeling under current (2024) and future (2050) scenarios.
  • The Kilitbahir site in the Çanakkale Strait was identified as the most suitable location for a 2 MW pilot facility, with estimated hourly hydrogen production of 22.413 kg in 2024 and 37.137 kg by 2050.
  • The study applied and tested the proposed framework in TÜRKEY, where ten candidate coastal locations were assessed as a case study.
  • The Levelized Cost of Electricity (LCoE) values for 2024 ranged between 98.24 and 100.66 USD/MWh, decreasing to between 42.24 and 42.85 USD/MWh by 2050.
  • The Levelized Cost of Hydrogen (LCOH) for 2024 was calculated at 8.808 to 8.973 USD/kg, dropping to 2.34 to 2.365 USD/kg in the 2050 projection.
  • The study's novelty lies in its integration of spatial decision-making, emerging marine technologies, and forward-looking economic modeling.
