Calculation of the Extra Capacity Required of Non-Fossil Fuel Power Generation Systems to Completely Phase Out Fossil Fuels
Abstract
The task to phase out fossil fuels is now at hand. Most studies and publications to date focus on why fossil fuels should be phased out. This paper presents the physical requirements in terms of required non-fossil fuel industrial capacity, to completely phase out fossil fuels, and maintain the existing industrial ecosystem. The existing industrial ecosystem dependency on fossil fuels was mapped by fuel (oil, gas, and coal) and by industrial application. Data was collected globally for fossil fuel consumption, physical activity, and industrial actions for the year 2018. The number of vehicles in the global transport fleet was collected by class (passenger cars, buses, commercial vans, HCV Class 8 trucks, delivery trucks, etc.). The rail transport network, the international maritime shipping fleet, and the aviation transport fleet were mapped, in terms of activity and vehicle class. For each type of vehicle class, the distance travelled was estimated. Non-fossil fuel technology units that are commercially available on the market now were assembled to substitute fossil fuel supported technology. An example was selected to represent each vehicle class, for Electrical Vehicle and Hydrogen fuel cell systems. The requirements to substitute the ICE rail network and the maritime fleet with EV and hydrogen fuel cell systems were presented. The quantity of electrical power required to charge the batteries of a complete EV system was estimated. The quantity of electrical power to manufacture the required hydrogen for a complete H-cell system was estimated. An examination and comparison between EV and H-cell systems was conducted. Other fossil fuel industrial tasks like electrical power generation, building heating with gas and steel manufacture with coal were mapped and requirements for non-fossil fuel substitution were out estimated…
