Hydrogen and hydrogen-related technologies will have an important role in world energy projection in the near future. Interest in hydrogen technologies will also increase, especially due to the smart cities concept and the increase in renewable energy supply. In addition to being a clean energy source, the tendency of hydrogen to 100% renewable energy supply makes it ahead of other alternative fuels. The share of hydrogen and related energy technologies in reducing global warming and emissions will continue to increase day by day. For this reason, projections and investment opportunities should be determined for the coming years. In energy projections, the evaluation of hydrogen in terms of energy diversity until 2030 is carried out with EnergyPlan software. Accordingly, the reduction in the amount of emissions and costs were determined by mixing hydrogen into the natural gas pipelines by 5 -10, and 20% by volume by producing electrolyzers with photovoltaic systems and according to the number of vehicles with fuel cells in the transportation sector until 2030.
