Floating offshore wind power could be the powerful key to reaching decarbonization targets

Introduction

Floating offshore wind power is emerging as a promising solution to harness the power of winds over the ocean and accelerate the transition to clean energy. While fixed turbines have been successful on the East Coast of the US, the challenge lies in deploying them in regions with deep waters, such as the West Coast. In this article, we will explore the future of floating offshore wind power, the advantages it offers, and the innovative technologies being developed to overcome engineering challenges.

The Potential of Floating Offshore Wind Power

Winds over the ocean have the potential to consistently blow at higher speeds compared to land, making them an attractive resource for generating electricity. However, traditional fixed turbines cannot be deployed in waters deeper than 60 meters, limiting their use in areas with abundant offshore wind resources. According to the Global Wind Energy Council, around 80 percent of the world’s offshore wind resources are located in deeper waters.

Floating offshore wind farms offer a solution to tap into these deep-water resources. By utilizing floating platforms, turbines can be installed further from shore, avoiding the “not-in-my-backyard” issue. This opens up vast offshore wind potential in regions like Europe, the United States, and beyond. The Biden administration, for instance, has unveiled the Floating Offshore Wind Shot initiative with the aim of reducing costs and increasing capacity to power millions of homes.

Engineering Challenges and Innovative Solutions

Deploying floating wind turbines in deep waters presents significant engineering challenges. The platforms need to support massive turbines, some exceeding 15 megawatts in size, while maintaining stability in rough seas and high winds. Additionally, the construction and installation processes must be cost-effective and efficient.

Several companies, including Gazelle Wind Power, are developing innovative floating wind platforms specifically designed for the offshore wind industry. Unlike many competitors that rely on legacy solutions from the oil and gas industry, Gazelle’s platform is uniquely tailored to address the requirements of floating offshore wind power.

Benefits of Floating Offshore Wind Power

  • Harnessing Stronger Winds

One of the key advantages of floating offshore wind power is the ability to tap into stronger and more consistent winds over the ocean. Unlike on land, where obstacles can obstruct wind flow, the unobstructed expanse of the ocean allows for the uninterrupted capture of high-speed winds. This translates into increased energy production and greater efficiency compared to onshore and fixed offshore wind farms.

Floating offshore wind farms are uniquely suited to operate in waters deeper than what fixed turbines can accommodate. As approximately 80% of the world’s offshore wind resources are located in areas with deeper waters, the ability to harness wind energy in these regions is crucial for the expansion of offshore wind power.

  • Flexibility in Location

With floating offshore wind farms, the issue of “not-in-my-backyard” is mitigated as they can be positioned far from the shoreline. This flexibility in location allows for the development of wind farms in areas that have less impact on coastal communities and natural habitats. It also opens up opportunities for the utilization of offshore wind resources in regions that were previously inaccessible.

Gazelle Wind Power’s Novel Solution

Gazelle Wind Power, a Dublin-based company, has recently unveiled a modular floating wind-platform design that offers several advantages over traditional solutions. This innovative design utilizes less steel, making the platform cheaper, lighter, and easier to install. By reducing the amount of steel required, a 1-gigawatt offshore wind farm using Gazelle’s solution can save over 142,000 metric tonnes of steel and significantly reduce carbon dioxide emissions.

The key features of Gazelle’s platform are pivoting arms and a dynamic mooring system. The platform is anchored to the ocean floor using vertical mooring lines, which are attached to a counterweight suspended beneath the center of the platform via pivoting arms. This unique design allows the platform to move with the wind and waves while maintaining stability and low turbine pitch.

Advantages of Gazelle’s Floating Wind Platform

Gazelle’s floating wind platform offers several advantages over conventional solutions. Firstly, the platform is smaller and lighter, resulting in a 30 percent reduction in costs compared to traditional semisubmersible designs. The modular nature of the platform enables easy installation without requiring specialized equipment, reducing project timelines and costs further.

Moreover, Gazelle’s platform can be tailored to accommodate turbines of various sizes, including megaturbines exceeding 20 megawatts. By deploying larger and more powerful turbines, the efficiency and cost-effectiveness of floating offshore wind farms can be maximized.

 Progress and Future Outlook

The floating offshore wind industry is gaining momentum worldwide. In 2021, three floating wind projects with a total capacity of 57.1 megawatts came online. Norwegian energy firm Equinor’s Hywind Tampen is currently the world’s largest floating wind farm, and it produced its first power in late 2020. The Biden administration’s commitment to expanding floating offshore wind capacity in the United States further emphasizes the potential of this technology.

According to research provider BloombergNEF, floating wind installations are expected to take off starting in 2027, primarily in Europe and the United States. The ability to harness stronger and less intermittent winds in deeper seas will contribute significantly to decarbonization efforts. Innovative solutions like Gazelle’s floating wind platform will play a crucial role in realizing the full potential of floating offshore wind power.

Conclusion

Floating offshore wind power presents a promising solution for tapping into deep-water wind resources and accelerating the transition to clean energy. The ability to deploy larger turbines further from shore opens up vast offshore wind potential, contributing to the goal of decarbonization. Gazelle Wind Power’s innovative floating wind platform offers a cost-effective and efficient solution, reducing steel usage, emissions, and project timelines. With the industry gaining momentum, floating offshore wind power is set to revolutionize the future of renewable energy.
