Current Status and Prospective of Offshore Wind Power to Achieve Korean Renewable Energy 3020 Plan

Abstract

This review comprehensively reviewed floating offshore wind power generation technology, which is being newly developed as a mid- to long-term plan for wind energy. From the perspective of investment per megawatt (MW), offshore wind power is still about 50 percent more expensive than land wind power. Nevertheless, many advanced countries began to investigate the data because they wondered why they were immersed in development and investment, and why offshore wind facilities installed on the beach and floating offshore wind installed in the middle of the sea, unlike the land wind we knew. We looked at the basic principles of offshore wind power generation and the technologies used in facilities, and looked at the advantages and disadvantages of offshore wind power generation compared to land wind power generation, and what differences between fixed offshore wind farms and floating offshore wind farms. It is investigated whether it is a realistic plan to verify residents’ opposition to the installation of offshore wind power facilities, the possibility of commercialization such as high operational management costs, and the feasibility of installing facilities for renewable energy 3020 as mid- to long-term goals. In addition, it compares foreign cases with offshore wind power development complexes in Korea, marine wind power generation complexes in operation, and high wind power in Scotland, the first floating offshore wind power in Ulsan, Korea, to overcome difficulties in installing facilities and suggest directions for domestic offshore wind power development. In addition, in Korea, where there are not many countries suitable for wind power generation unlike overseas, it was decided to investigate whether floating offshore wind power could be the answer as planned. The reason why the government is pushing for investment in renewable energy such as solar power and wind power is because energy sources from the sun are eco-friendly. However, the U.S. and Europe, which started the wind power project early, are having difficulty in handling the wings of wind power generators. The energy source looked at the contradictions caused by environmental pollution in the treatment of waste, although it was environmentally friendly, and investigated how waste was treated and utilized overseas. Compared to other countries that entered the offshore wind power business earlier, domestic power generation projects are in their infancy and should focus on developing technology and co-prosperity with neighboring residents rather than on excessive expansion.

Tracking Trends for Offshore Wind Energy Industries and Infrastructures in the South Korea: Focused on the Jeonnam Shinan 8.2GW and Ulsan 6GW Offshore Wind Farm Projects

“…The Renewable Energy 3020 Plan means that Korea plans to build a total of 63.8 GW of renewable energy facilities to increase the proportion of renewable energy generation to 20% by 2030. The government promoted large-scale national projects to increase new and renewable energy power generation facilities, and at the same time introduced a local government-led planned location system for the participation of many people [12,13]. This is a system to encourage resident participation in renewable energy projects and to share profits.…”

A Study on Grid-Cell-Type Maritime Traffic Distribution Analysis Based on AIS Data for Establishing a Coastal Maritime Transportation Network

“…Recently, research on marine development planning and the development of different types of operational ships for use in Korean coastal waters in a variety of ways has accelerated. The establishment of offshore wind farms in line with the Green New Deal policy and Renewable Energy 3020 implementation plan, as well as the establishment of marine port facilities to encourage marine leisure, are major maritime development plans [1,2]. Moreover, different types of navigation technologies from existing vessels are being developed, such as autonomous ship technology, which allows the system to control the ship and operate it without human interference by converging information communication, sensors, and smart technologies with existing ship technology, including water-surface flying ships, which operate at a height close to the surface of the water [3,4].…”

Foundation Types of Fixed Offshore Wind Turbine

“…In the case of offshore wind power, it is easy to construct large power generation complexes compared to onshore wind power, and the construction causes fewer complaints. It also provides high energy efficiency because the wind speed is 70% higher on average than onshore wind power (Park et al, 2021). Despite this, offshore wind power is difficult to install because of the complex marine environment and requires higher installation costs than onshore wind power.…”
