Abstract
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.
Highlights
Since December 2019, there has been outbreak of novel corona virus named covid-19 reported to have emerged from Wuhan in china
Distributed production facilities are smaller in scale and closer to the consumers. As such distributed generations can meet the demand from transportation sector of hydrogen powered fuel cell vehicles during the transition period to a hydrogen economy and once the market expands, the hydrogen production will be scaled up and ‘centralized’ to take advantage of economies of scale as well as the higher efficiency from larger scale production and to meet the greater amount of hydrogen demand in industrial sector
No doubt Post covid-19 pandemic will be a time for global energy shift toward hydrogen economy
Summary
Since December 2019, there has been outbreak of novel corona virus named covid-19 reported to have emerged from Wuhan in china. As an industrial and transport tend to seek fuel option while considering environmental concerns, hydrogen exhibits numerous advantageous properties including its high diffusion velocity, highest heating value of any fuel (per kilogram), wide range of flammability and detonability limits, low ignition energy, high flame speed, and nontoxicity. 1.5 Sources of hydrogen Hydrogen can be source from variety of primary energy such as fossil fuels, nuclear [20], solar [21], wind [22], hydropower [23] and geothermal energy [24] Different energy resources with various pathways can be utilized to generate hydrogen Various processes such as methane steaming steam reforming, water electrolysis, high temperature electrolysis, and thermochemical cycles are available to produce hydrogen as well. As such distributed generations can meet the demand from transportation sector of hydrogen powered fuel cell vehicles during the transition period to a hydrogen economy and once the market expands, the hydrogen production will be scaled up and ‘centralized’ to take advantage of economies of scale as well as the higher efficiency from larger scale production and to meet the greater amount of hydrogen demand in industrial sector
