Global offshore wind energy resources are abundant and have a vast market demand as renewable energy. Due to offshore wind power's randomness, intermittency and anti-peaking characteristics, there are still many challenges for its large-scale grid-connected consumption. Offshore wind power hydrogen production technology can effectively improve the utilization rate of wind power and has become a hot direction for offshore wind power development and research. Therefore, the transportation of hydrogen to shore is a crucial part, especially important in terms of safety and economy. This paper studies the technical solutions of pipeline and ship transportation for offshore wind power hydrogen production. The economic model of pipeline and ship transportation for offshore wind power hydrogen production is established by integrating the benefits of hydrogen sales, equipment investment, operation, maintenance and decommissioning dismantling costs. The economic comparison of offshore wind power hydrogen production and transportation schemes for different offshore distances, considering the costs varying of unit production, is also introduced in this pater. These results reveal that the economic benefits of the project can be significantly improved by improving the service life of the relevant equipment and reducing the construction cost, and pipeline transportation takes a financial advantage when the offshore distance is close, and ship transportation takes advantage when the offshore distance is far. The longer the operation time, the stronger the compensation effect on the project's investment cost.
