Hydrogen energy is the most promising secondary energy source in the future and has a significant effect on the development of low-carbon economy. However

using fossil energy to produce hydrogen will cause a large amount of CO_2 emissions while obtaining H_2

which severely restricts the development of hydrogen energy. Carbon capture

utilization and storage(CCUS) is a CO_2 emission reduction technology. The coupling of hydrogen energy and CCUS technology is conducive to the coordinated development of hydrogen energy and CCUS industry. The full text systematically investigates the national hydrogen energy industry development policies and plans from the national level

and compares the hydrogen energy development policies and CCUS incentive policies. On the basis of the development scale of hydrogen energy

it analyzes the CO_2 emission scale of the hydrogen energy in typical regions. Moreover

the paper evaluates the source and sink matching of hydrogen energy and CCUS based on the reduction potential of the CCUS in typical regions. The impact of the synergy of the two on the local economy

employment and production capacity release is also investigated. At the technical level

the carbon emission characteristics of the hydrogen energy technology chain are analyzed

the feasibility of coupling hydrogen energy with CCUS technology is discussed

and suggestions for coupling optimization are proposed. Through policy coordination

technology coupling

and promotion and demonstration at different levels

hydrogen energy and CCUS can achieve coordinated development in the future energy industry.
