The power industry continues to be a hotbed of patent innovation. Activity is driven by increasing global power demand, renewable energy auctions, and  the growing importance of technologies such as offshore wind turbines, floating platforms, and interconnectors. In the last three years alone, there have been over 656,000 patents filed and granted in the power industry, according to GlobalData’s report on Innovation in power: offshore wind turbine pre-assembly.

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early emergence to accelerating adoption, before finally stabilizing and reaching maturity.

Identifying where a particular innovation is on this journey, especially those that are in the emerging and accelerating stages, is essential for understanding their current level of adoption and the likely future trajectory and impact they will have.

40+ innovations will shape the power industry

According to GlobalData’s Technology Foresights, which plots the S-curve for the power industry using innovation intensity models built on over 70,000 patents, there are 40+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, variable speed gas turbines is a disruptive technology that is in the early stages of application and should be tracked closely. Perovskite photoactive layering, power distribution control system, and CAES gas turbines are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are geothermal heat pumps and prepaid electricity metering, which are now well established in the industry.

Innovation S-curve for the power industry

Offshore wind turbine pre-assembly is a key innovation area in power

A tower for an offshore wind farm typically consists of multiple components. All the pieces must be put together to create a complete tower and be prepared for installation at their final offshore location. The assembly work can be undertaken at the final offshore location, but it can be exposed to risks. Assembling and installing the foundation, tower and other parts of wind turbines before they are transported to, and erected at, their ultimate offshore location is known as offshore wind turbine pre-assembly.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 100+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of offshore wind turbine pre-assembly.

Key players in offshore wind turbine pre-assembly – a disruptive innovation in the power industry

‘Application diversity’ measures the number of applications identified for each patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.   

‘Geographic reach’ refers to the number of countries each patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Siemens is one of the leading patent filers in offshore wind turbine preassembly. In May 2023, FairWind was awarded the turnkey pre-assembly contract for the offshore wind farms Vesterhav Nord and Syd at the Port of Esbjerg, Denmark. FairWind will be responsible for the pre-assembly erection of 41 Siemens Gamesa’s SG 8.0-167 DD turbines. In August 2023, Global Wind Projects was awarded a contract by Siemens Gamesa for the pre-assembly of 54 wind turbine towers for the 450MW Neart na Gaoithe (NnG) offshore wind farm, being developed by EDF Renewables and ESB off the coast of Scotland. Some other key patent filers in the automotive industry include General Electric, Wobben Properties, and Vestas Wind Systems.

In terms of application diversity, Kolon Global leads the pack, while Toda and Toda Construction Shanghai stood in the second and third positions, respectively. By means of geographic reach, Actividades de Construccion y Servicios held the top position, followed by Keppel Group and Toda.
