A Perspective on Decarbonizing Mobility: An All-Electrification vs. an All-Hydrogenization Venue

The growing demand for low-carbon fuel is predicted by ultimate goals to fit the carbon neutrality 2050 in many countries and regions including European Union. According International Energy Agency, CO2 emissions related transportation stand around 30% of total annual emissions, so, decarbonization mobility sector has highest priority. In this work, we attempt evaluate expected fuels, blue green hydrogen, electricity order compare available required capacities fuels electricity. our calculations based on figures from 2020, transition toward H2 would require an amount hydrogen equal 366 million tons/annum, 2035, requirement will increase up 422 which several times larger than existing production capacities. We have estimated volume capture storage facilities full globally, case driven it exceeds 4.0 billions tons per annum, while coal-fired plants more 10.0 annum. addition calculation resources, cost capital investments compared different possible solutions points view: economic viability, technical readiness, social perception. Finally, can be concluded that a complex solution involving both electrification, must significantly increased following decade fulfill climate goals.
