The significance of Realizing a Hydrogen Energy Society:Energy Saving: Use of fuel cells enables high energy efficiency.Energy Security: Hydrogen can be produced from various primary energy sources, including unutilized energy sources such as by-product hydrogen, flaring gas, and brown coal; and renewable energy sources. Procuring these energy sources from areas of relatively low geopolitical risk leads to enhancing energy security, and using renewable energy promotes energy self-sufficiency.Environmental Load Reduction: Hydrogen does not emit CO2 when consumed. Applying Carbon Capture and Storage (CCS) technology to hydrogen production or using renewable energy enables a completely CO2-free system.Industrial Promotion: Japan is ranked first in patent applications regarding fuel cells and is strong in this field.
