OFFSHORE ENERGY STORAGE MARKET
The process of storing energy produced by renewable sources, such as wind or solar power, in facilities that are offshore is known as offshore energy storage. In order to store extra energy during times of high generation and release it when there is a need or when the renewable source is not actively producing power, it entails the use of a variety of storage technologies.
Offshore energy storage has drawn interest as a potential remedy for the erratic nature of renewable energy sources and to increase the stability and dependability of the grid.
Utilizing the enormous offshore wind resources and available space is one of the main benefits of offshore energy storage. As wind speeds change and the power generation can be variable, offshore wind farms frequently encounter problems linked to intermittency.
A more steady and dependable power supply can be achieved by incorporating energy storage technologies, which will allow excess wind energy produced during peak wind periods to be absorbed and stored for later use.
Offshore deployments of several energy storage systems are possible. The usage of battery energy storage systems (BESS) is one such strategy. For instance, lithium-ion batteries are ideal for offshore applications because of their high energy density, quick response times, and modular deployment capabilities.
These battery systems can ensure a steady supply of electricity to the grid by storing excess energy during times of low demand and discharging it during periods of peak demand or when the wind speed declines.
Compressed air energy storage (CAES) is another possibility for offshore energy storage. This method uses surplus electricity to compress air, which is then stored in subterranean caverns or undersea constructions.
The compressed air is released when the energy is needed, which then powers turbines to produce electricity. In comparison to batteries, CAES systems are capable of storing a lot of energy and have a longer discharge time. They may be especially well suited to offshore settings, where space restrictions are less of an issue.
Another new option for offshore energy storage is hydrogen storage. Hydrogen can be created through water electrolysis using surplus electricity, and it can then be stored for use as a fuel source in future power plants or for other purposes.
Large tanks can be used to store hydrogen, which can also be moved using pipelines or ships. Since it may be utilized for various industrial processes or converted back into electricity using fuel cells, its adaptability as an energy carrier makes it a desirable alternative for offshore storage.
Systems for offshore energy storage have various advantages. They can support grid stabilization, supply and demand balancing, and better integrating of renewable energy sources into the current energy infrastructure.
Offshore storage systems can decrease curtailment, lessen the need for fossil fuel-based backup power plants, and enable a larger penetration of renewable energy into the grid by storing excess renewable energy and releasing it during times of high demand.
Furthermore, the difficulties brought on by a lack of onshore space, visual impact issues, and potential conflicts with other land uses can be avoided by putting energy storage facilities offshore.
Utilizing the existing transmission connections and infrastructure, offshore installations can be placed close to offshore wind farms that are already operational or are slated for construction.
Offshore energy storage does, however, come with difficulties. Subsea cables and other specialized infrastructure are needed to link the storage systems to the grid.
In comparison to on-shore installations, maintenance and monitoring of offshore storage facilities can be more difficult and expensive. Environmental factors including the effect on marine habitats and the potential for stored material leakage must be properly taken into account.
In conclusion, offshore energy storage is a viable strategy to increase grid stability and further the integration of renewable energy sources. Offshore storage systems can reduce the erratic nature of renewable energy sources and offer a more dependable and robust source of power by storing excess energy produced by offshore wind or other renewable sources for later use.
Unlocking the full potential of offshore energy storage and expediting the transition to a sustainable energy system will depend on continued developments in energy storage technologies, as well as supportive policies and investments.
Energy storage systems must connect to offshore and onshore grids, requiring high-voltage direct current (HVDC) converters and transmission infrastructure.
The Global Offshore Energy Storage Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Siemens Energy and Aker Solutions have signed a Memorandum of Understanding (MoU) to collaborate on the development of offshore energy storage systems. The two companies will combine their expertise in offshore wind, energy storage, and subsea engineering to develop innovative and cost-effective offshore energy storage solutions.
Equinor, Norwegian energy company, has announced plans to deploy the world’s first floating battery system at its Hywind Tampen offshore wind farm. The battery system will be used to store and deliver energy from the wind farm, helping to balance the grid and provide backup power.
EDF Renewables, the renewable energy arm of EDF Group, has announced plans to develop a 400 MW offshore energy storage project off the coast of New Jersey. The project will use a combination of battery and pumped hydro storage technologies.
Europe is expected to dominate the global offshore energy storage segment during the forecast period, owing to an increased investment in renewable sectors, such as, solar- powered, onshore, and offshore wind energy, and geothermal energy. A key figure driving investment in renewable technologies is the implementation of strict ecological guidelines with limited fossil fuel by products.
North America is expected to hold a significant share of the global offshore energy storage market owing to the implementation of smart city projects and the rise in demand for IoT gadgets incorporated with environmentally friendly power sources in the region.
Hitachi completes the acquisition of ABB power grids in July 2021 to address renewable energy, establish a distribution channel to the power industry, and expand its access to the utility segment in all regions.
Tesla acquired Maxwell Technologies Inc. in May 2020 to increase the energy holding capacity of the standard capacitors. This will broaden its product range of applications including transportation, industrial, and grid energy storage.
A new lithium-ion-based energy storage system for ships has been introduced by Rolls-Royce. For a shipowner, the energy storage system (ESS) represented a significant “green investment,”
According to Rolls-Royce, Save Energy, a liquid-cooled battery system with a modular construction that enables the product to scale in accordance with energy and power requirements is now a product offered by Rolls-Royce.
Save Energy confirmed with worldwide laws governing low- and zero-emission propulsion systems, the business stated. Rolls-Royce claims that profits are maximized when the system is appropriately sized for the particular vessels and has intelligent power control. The ENERGIX program of the Norwegian Research Council in Norway has contributed to the cost of developing the ESS.
A wide range of marine applications, including ferries, cruise ships, and multipurpose vessels, are covered by the energy storage system thanks to the involvement of three ship-owning businesses, Color Line, Norled, and the Norwegian Coastal Administration Shipping Company.
As part of the company’s provision of entire ship systems, the SAVe Energy system will be shipped from the Rolls-Royce Power Electric facility in Bergen, Norway.
On several of the projects we are now working on, SAVe Energy is being used. This includes the Hurtigruten cruise ferry upgrading program, the cutting-edge fishing vessel that Prestfjord recently ordered, and the ongoing offshore support vessel retrofits. Peak shaving, spinning reserves, and battery-powered boats are just a few places where SAVe Energy can be used.
