Hydrogen as a Sustainable Mobility Fuel: A Global Perspective and Opportunities for India

Reducing greenhouse gasses (GHGs) emissions has become a prime concern worldwide. Transportation is one of the important sectors, responsible for emitting about 17 percent of GHGs and other harmful gases globally. To overcome the same and supplement battery electric vehicles, hydrogen is proposed as the fuel of the future for the transportation sector. It can either be burnt in internal combustion engines or used in fuel-cell electric vehicles. Many countries support the research and development of hydrogen-powered vehicles due to their climate-friendly attributes. In this direction, this review paper aims to compile hydrogen policies and roadmaps related to the mobility sector from different countries. The paper also presents the scope of hydrogen as a sustainable fuel in India, exploring its socio-economic aspects and deployment scenarios.
