The power industry continues to be a hotbed of patent innovation. Activity is driven by the rising demand for electricity, shift away from fossil fuel-powered generation and the need for reduced greenhouse gas emissions, and growing importance of technologies such as heat exchangers and cooling systems. 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: nuclear reactor cooling systems. Buy the report here.

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 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 turbine 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

Nuclear reactor cooling systems is a key innovation area in renewable energy

Most reactor systems employ a cooling system that is physically separated from the water that will be boiled to produce pressurised steam for the turbines, like the pressurized water reactor. However, in some reactors the water for the steam turbines is boiled directly by the reactor core, for example the boiling water reactor. 

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 40+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of nuclear reactor cooling systems.

Key players in nuclear reactor cooling systems – 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’.
