Earth does not have an equal distribution of energy sources. Despite the advances in renewable energy, fossil fuels seem to continue to dominate the energy sector in near future. Hydrogen energy is seen as a renewable power system that is an alternatively convenient storage and transmission vector. The present study aims to contribute to the discussion on the implementation of the hydrogen power plants through encouraging state sector investments in renewable energy and private sector investments in hydrogen energy. In this respect, the contribution of hydrogen energy to energy efficiency is that it can reveal the potential of suitable and sustainable energy as a natural source at a competitive price in the future. The study also aims to contribute to energy efficiency by emphasizing the significance of maintaining an international strategic planning process for public and private sector officials to accelerate the effective development of the hydrogen economy infrastructure. The study also underlines that it is essential for the governments to encourage initiatives concerning renewable energy and fuel cell in the process of transition to hydrogen economy in the 21st century.
