In this study, an integrated system is designed to produce renewable hydrogen and blend it with natural gas available in the Black Sea in the City of Zonguldak for countrywide utilization, and a case study is, in this regard, considered for Turkey. To use the natural gas reserves in a more efficient and environmentally friendly manner, blending it with the addition of 20% hydrogen by volume is the prime focus of this study. For this purpose, hydrogen production capacities from renewable energy sources such as solar, wind, and wave are calculated and found out as 174,210 kg, 1432 kg, and 1257 kg, respectively. The effects of hydrogen addition on blend gas consumption and the lifetime of existing reserves are investigated. With the addition of 20% hydrogen by volume, annual blend gas consumption increased from 46.55 billion m3 to 54.11 billion m3, while natural gas consumption decreased from 46.55 billion m3 to 43.29 billion m3. Thus, the reserve life has increased from 11.6 years to 12.5 years.
