Global carbon dioxide emissions pressure gives a good development opportunity for hydrogen energy， and it also accelerates the development of hydrogen energy technology. The water decomposition is the main direction of hydrogen production technology， but it needs huge electricity energy consumption. In order to reduce the cost of hydrogen energy， the water decomposition should rely on other clean energy such as solar energy， wind energy. For the wind intermittent fluctuation and non-grid-connected features， the paper explores the development and utilization of rich wind energy resources in the Yellow Sea radial sand ridges， and proposes the hydrogen production technology based on non-grid-connected wind power. The application mode and ways of hydrogen energy in green traffic are analyzed for expanding the comprehensive development of wind power resources， hydrogen energy and green transportation.
