The expansion of BRICS and its impact on the use of renewable energy sources: a case study of hydrogen energy

Considering the increasing energy needs and environmental challenges in the world, BRICS members have also put in place a policy of reducing dependence on fossil fuels and moving towards more sustainable energy sources. This study aims to investigate the role and impact of the expansion of this bloc on the development and use of renewable energies, with a special focus on hydrogen energy. In this article, the combined method (quantitative and qualitative) and the theoretical framework of sustainable development and energy transition have been employed. Based on the results, BRICS can play an important role in accelerating the development of hydrogen energy by using policies such as knowledge and technology exchange between member countries, increasing investment in research and development of hydrogen energy, and financing hydrogen energy production infrastructure projects by the new BRICS Development Bank.
