Floating Offshore Wind Power
The Promise of Floating Offshore Wind Energy for Decarbonization and Sustainability
Floating offshore wind energy is a clean, renewable energy source harnessed from strong, consistent winds found offshore, where there are fewer barriers. It plays a crucial role in decarbonization due to its high potential and strategic value both socioeconomically and environmentally. Unlike traditional offshore wind, which uses fixed structures, floating offshore wind uses floating structures, enabling wind turbines to be deployed in deeper, more distant offshore areas with higher wind potential. This innovation provides new opportunities for clean, inexhaustible energy.
Advantages include a potentially low environmental impact and ease of manufacture and installation, as turbines and platforms can be built on land and towed to their sites. Additionally, accessing stronger winds in deeper waters enhances energy efficiency.
How Floating Offshore Wind Energy Works:
1. Buoyancy Principle: Wind turbines float in the sea due to the principle of buoyancy, which was discovered by Archimedes. This principle states that a submerged body experiences an upward force equal to the weight of the displaced water, allowing large structures to float.
2. Floating Offshore Wind Platforms (FOWPs): FOWPs are substructures made from concrete, steel, or a combination of materials that support wind turbines, providing them with buoyancy and stability. Unlike foundations that rest on the seabed, these platforms are anchored and moored in place.
3. Structure and Stabilization: Floating wind farms consist of turbines mounted on floating platforms. These platforms are stabilized through moorings and anchors, and the design ensures proper weight distribution to maintain stability.
4. Energy Conversion: The wind turns the turbine blades, and the turbine converts this kinetic energy into electricity. This electricity is transmitted via underwater cables to an offshore substation, then to an onshore substation, and finally distributed to homes via power lines.
5. Maintaining Stability: To maximize energy production, floating wind turbines must remain stable, minimizing movement to operate efficiently. Different types of floating platforms are designed to ensure this stability, adapting to various marine conditions.
Types of Floating Platforms For Wind Turbines:
These are some common types of floating platforms for wind turbines:
1. Barge: Large surface area in contact with the water for stability, often equipped with heave plates to minimize movements. The WindFloat Atlantic project off the coast of Portugal utilizes a barge-type floating platform. Each platform supports a wind turbine and is moored in place using a combination of cables and anchors. These barges have a large surface area in contact with the water, providing stability even in rough sea conditions.
2. Semi-submersible: Maximizes volume for buoyancy while minimizing exposed surface area, typically consisting of vertical cylinders joined by beams and braces. The Hywind Scotland project, located off the coast of Scotland, employs semi-submersible floating platforms. These platforms consist of multiple vertical columns submerged beneath the water’s surface, connected by beams and braces. The design maximizes buoyancy while minimizing exposure to waves and wind.
3. Spar: Stability is achieved by placing most of the weight at the lowest point of the structure, often using a hollow cylinder with added mass at one end to maintain verticality. The Gulfstar One platform in the Gulf of Mexico is an example of a spar-type floating platform for wind turbines. It features a hollow cylindrical structure with added mass at the base to maintain stability. The platform supports a wind turbine atop the cylinder, harnessing wind energy in offshore environments.
4. Tensioned Legs Platform (TLP): Utilizes a star geometry with tensioned steel cables or tendons for stability, minimizing dimensions and manufacturing costs. The Fukushima Forward project off the coast of Japan showcases the TLP design for floating wind turbines. This innovative platform consists of a star-shaped geometry with tensioned steel cables providing stability. By minimizing dimensions and utilizing tensioned legs, TLPs aim to reduce manufacturing costs and environmental impact while maximizing energy production.

With hydrogen already established as a fuel for various modes of transportation since the 19th century, its role in industrial applications continues to evolve.
The imperative shift towards decarbonizing the global economy further underscores the potential of hydrogen. If production costs can indeed decrease by 50% by 2030, as anticipated by the World Hydrogen Council, hydrogen is poised to become a key player in the future of energy. Central to this technology is electrolysis, a chemical process that generates hydrogen – a versatile, lightweight, and highly reactive fuel.
This method uses an electrical current to separate the hydrogen from the oxygen in water. If this electricity is obtained from renewable sources we will, therefore, produce energy without emitting carbon dioxide into the atmosphere. As the IEA points out, this method of obtaining green hydrogen would save the 830 million tonnes of CO2 that are emitted annually when this gas is produced using fossil fuels.
Progress in Clean Hydrogen Development
Technological Advancements and Projects:
H2 Green Steel in Sweden: This startup is developing the world’s first large-scale green steel plant powered by Europe’s first giga-scale electrolyzer. It has raised €6.5 billion for its construction.
ACWA Power in Saudi Arabia: This company has initiated a 2.2 GW green hydrogen project, with plans to export hydrogen in the form of green ammonia to Europe, reflecting the project’s global impact.
Global Hydrogen Investments: Projects are scaling up from 20 MW to several 100-250 MW facilities. The Green Hydrogen Catapult coalition, including major players like H2 Green Steel and ACWA, is on track to reach 45 GW of green hydrogen projects by 2030. Read More
Policy and Economic Incentives:
World Bank’s 10 GW Initiative: The World Bank has proposed a 10 GW clean hydrogen initiative to boost the adoption of low-carbon energy, focusing on regions with high renewable energy potential but limited current infrastructure. Read more
Inflation Reduction Act in the U.S.: This act provides significant tax credits for green hydrogen production, aimed at reducing emissions and encouraging investment in renewable energy sources.
Sustainable Steel Buyers Platform (SSBP): This platform brings together corporations from the automotive, tech, and construction industries to support zero-emission steel production using hydrogen. It aims to pool demand and make green steel projects financially viable.
High Production Costs:Producing hydrogen through electrolysis using renewable energy is still expensive. Costs need to be reduced to make green hydrogen competitive with fossil fuels.
Scaling Up Infrastructure: Building the necessary infrastructure for production, storage, and distribution at a global scale presents a significant challenge. Existing projects are often limited in scale and concentrated in specific regions.
Inconsistent Regulations: Different countries have varying regulations and standards for hydrogen production and usage, which can hinder international collaboration and market development.
Additionality and Emissions Accounting: There are debates over how to ensure that hydrogen production genuinely uses additional renewable energy, rather than displacing it from other uses. This affects the credibility and effectiveness of carbon reduction claims
Market Demand and Offtake:
Securing Offtake Agreements: One of the biggest barriers to project development is the lack of guaranteed demand. Companies need long-term agreements to ensure a market for the hydrogen they produce.
Sector-Specific Adoption: While sectors like steel and shipping show promise, widespread adoption across all industries is necessary to achieve a significant impact. This requires coordinated efforts and substantial investments in technology adaptation.
The clean hydrogen initiative is crucial for achieving global decarbonization goals. Significant progress has been made, with large-scale projects and supportive policies paving the way. However, challenges in cost, infrastructure, regulation, and market demand must be addressed to fully realize hydrogen’s potential. Continued innovation, investment, and international cooperation will be key to overcoming these obstacles and harnessing clean hydrogen’s full benefits.
