Hydrogen application technologies and environmentally friendly smart energy system

Abstract

Climate change and fossil fuel depletion are the main reasons for many countries around the world to develop and implement energy transition strategies. Being a very clean burning fuel (generating steam only), hydrogen will play an important role in the transition from fossil energy to CO2-free energy. The paper introduces recent advances of hydrogen technology applied in transportation, industry, and power generation in the world; challenges regarding hydrogen safety and technology; barriers in social perception; and some recommendations for the development of hydrogen technology and environmentally friendly smart energy systems in Vietnam.
