Covid-19 pandemic lockdown has slowed down the world economic system. The pandemic has cleared the roads, close factories and grounded planes causing severe economic challenges. The damaging impact of the pandemic amid lockdown has been a blessing in guise for the environment because of significant drop in pollution level as transport and industrial sectors shutdown. Transport and industrial sectors are major contributors to environmental degradation through various emissions as a result of fossil fuel consumption. Energy consumed by transport and industrial sectors will have to shift to viable, readily available, clean, storable, economically and environmentally friendly with no carbon build up post Covid-19 pandemic. Hydrogen energy remains the best alternative option technologies containing greenhouse gas emission and pollutions of several forms. Hydrogen holds the potential to provide a clean, reliable, renewable and economical source of energy for meeting the growing and unending global energy needs post pandemic. The present paper explores prospect of hydrogen gas energy to serve as a competitive fuel option post pandemic and the economic feasibility. In this paper, the role of hydrogen as an energy carrier, hydrogen economy structure, potential of hydrogen economy, hydrogen production methods, hydrogen application and the economic and environmental significance of hydrogen as a viable fuel option post Covid-19 pandemic were thoroughly discussed. There will be a surge in demand and investment for hydrogen economy post Covid-19 to achieve decarbonization of transport and industrial sectors.
