The "dual carbon goal" refers to the goal of reducing carbon dioxide and greenhouse gas emissions to combat climate change. In this context, sustainable energy ecosystems and renewable energy for hydrogen storage in airports have become the focus of research. Airports, as places with high energy consumption, are faced with the important task of reducing carbon emissions. Research on sustainable energy ecosystems aims to develop and apply various renewable energy technologies to meet the energy needs of airports. These technologies include solar energy, wind energy, biomass, etc. By utilizing natural resources and renewable energy sources around the airport, the dependence on conventional energy sources can be reduced, reducing the carbon footprint and lowering the environmental impact. Hydrogen production is a method of storing energy by converting electrical energy into hydrogen gas in order to convert it back into electricity when needed. In the study of renewable energy for hydrogen storage, airports can use renewable energy to generate electricity and use the electricity to break down water into hydrogen and oxygen. The hydrogen produced can be stored and supplied to the airport's energy system when needed. This hydrogen production and storage system is efficient and environmentally friendly, providing a continuous and stable energy supply to the airport and reducing dependence on conventional energy sources. The study of sustainable energy ecosystems and renewable hydrogen storage at airports can provide innovative solutions to achieve the "double carbon goal". The results of these studies will help promote sustainable airport energy development, reduce carbon emissions, improve air quality, and provide cleaner and more environmentally friendly energy options for future air traffic systems.
