The research of all things in Dacheng Famous Garden ｜ "The most promising clean energy" research has made progress

Green hydrogen refers to the use of hydrogen produced by renewable energy such as solar energy and wind energy, which is considered one of the most promising clean energy sources. Refining industry. In recent years, as a renewable energy medium suitable for long -distance transactions, green ammonia has become a new hot spot for many countries and multinational companies' energy transformation strategies. However, due to the lack of unified quantitative evaluation methods, its comprehensive impact of resources and environment, and sustainability is still a mystery.

Recently, this "most promising clean energy" has made research progress. The research results of the South China Botanical Garden of the Chinese Academy of Sciences show that improving the efficiency and recovery of minerals and freshwater is the key to ensuring the sustainability of "green ammonia".

It is reported that the South China Botanical Garden vegetation and landscape ecological research group and the Japanese National Institute of Technology (AIST) Lin Binle research team cooperated to develop a "life cycle assessment of life cycle assessment for comprehensive evaluation of various resource consumption, emissions and environmental impacts. -The Energy Evaluation (LCA-EME) integrated research method, and is used in Australia-Japan-Japan passenger transportation traffic green ammonia long-range coupling system resources and environmental impact assessment case research.

The results of the study show that the transition from fossil energy to green ammonia energy can reduce 30%of non -renewable energy consumption and 10%greenhouse gas emissions of the transportation system; Note. At the same time, the end environmental impact on human health and biological diversity will increase by 1.56 times; and the increase in these resources and environmental pressure will mainly occur in the production countries (regions) of green ammonia. The "internalization" green ammonia long -range coupling system "external" resource pressure and its terminal environmental impact, improving the efficiency and recovery of minerals and freshwater is the key to ensuring its sustainability.
