Gas supply system, gas supply method and hydrogen refueling station

Abstract

The invention belongs to the technical field of energy supply, and particularly relates to a gas supply system, a gas supply method and a hydrogen refueling station. The gas supply system comprises a gas unloading system, a compressor, a hydrogen storage tank, a filling system and a control system, wherein the gas unloading system is used for transferring hydrogen in gas source equipment to the compressor; the compressor is used for pressurizing the hydrogen and then filling the hydrogen into the gas storage tank; the filling system is used for filling the hydrogen in the gas storage tank into hydrogen filling equipment; the control system is used for monitoring the hydrogen pressure in the hydrogen filling equipment, the hydrogen pressure in the gas storage tank and the hydrogen pressure in the gas source equipment, and is also used for controlling the startup and shutdown of the gas unloading system, the compressor and the filling system; the gas supply system is modularly arranged; or the gas unloading system, the compressor, the hydrogen storage tank, the filling system and the control system are arranged in at least one skid-mounted box. The gas supply system can be flexibly arranged, the occupied area is reduced, and popularization and application of the hydrogen refueling station are promoted.

Description

technical field [0001] The invention belongs to the technical field of energy supply, and more specifically, relates to a gas supply system, a gas supply method and a hydrogen refueling station. Background technique [0002] As a clean, efficient, safe and sustainable new energy, hydrogen energy is regarded as the most promising clean energy in the 21st century. In recent years, the United States, the European Union, Japan and many other countries and regions have raised the development of hydrogen energy and fuel cells to the national strategic level, and formulated specific action plans, policies and development routes. The main reasons restricting the development of hydrogen energy at this stage are the high cost of hydrogen production and weak hydrogen energy infrastructure. Fuel cell vehicles and hydrogen refueling stations are an important part of the hydrogen energy industry. Hydrogen refueling station is an important infrastructure to provide hydrogen source for hy...

AI Technical Summary

Problems solved by technology

The advantage of in-station hydrogen production is that it can save hydrogen transportation costs and reduce the volume of hydrogen storage tanks in hydrogen refueling stations; the disadvantage is that hydrogen production equipment occupies a large area and its application is limited

The problems existing in the existing hydrogen refueling stations mainly include: 1) The number of hydrogen refueling stations is small and relatively scattered, which brings great inconvenience to the refueling of hydrogen fuel cell vehicles; 2) The equipment layout of existing hydrogen refueling stations is large, The large area also limits the promotion and application of hydrogen refueling stations; 3) The hydrogen refueling station has a long time span from project approval to completion and operation, and the on-site construction period is long; 4) Existing hydrogen refueling stations do not support users to use fuel cards, Gas card, charging card for settlement
