1.Nuclear energy as primary energy and hydrogen energy as secondary energy Fossil resources are unevenly distributed on the earth and are a finite source of primary energy that is widely used in industry(factories,etc.),transportation(automobiles,etc.),and energy conversion(power generation,etc.).It must be said that the mass consumption of fossil resources is non-sustainable.Primary energies that can replace fossil-fuel-based energy include renewable energy and nuclear energy,while hydrogen energy has the potential to be a secondary energy source that can be widely used in industry for various purposes,including the use of hydrogen as raw material for chemical products,a reducing agent,and fuel.For example,the International Energy Agency(IEA)has provided a roadmap[1]for achieving net-zero emissions by 2050,stating that about 530 Mt∙a^(-1)of global hydrogen is needed.This is about six times the hydrogen demand in 2020(about 90 Mt∙a^(-1)).
