The power industry continues to be a hotbed of innovation, with activity driven by rising demand for power and a shift to renewable energy, and the growing importance of technologies such as heat exchangers and cooling systems. In the last three years alone, there have been over 439,000 patents filed and granted in the power industry, according to GlobalData’s report on Innovation in Power: Steam turbine cooling system.

According to GlobalData’s Technology Foresights, which uses over 83,000 patents to analyse innovation intensity for the power industry, there are 90+ innovation areas that will shape the future

Steam turbine cooling system is a key innovation area in power

The cooling system of a steam turbine ensures the transfer of thermal energy from one medium to another while avoiding the overheating of equipment. Cooling systems can be divided into once-through cooling system, closed recirculating/dry cooling tower, and open recirculation/wet cooling.

GlobalData’s analysis 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 are20+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of steam turbine cooling system.

Key players in steam turbine cooling system – a disruptive innovation in the power industry

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

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

Siemens is one of the leading patent filers in the cooling system industry. The smart cooling system offered by the company is efficient and reduces the cooling down time by up to 50% which results in reduced production losses and enhanced turbine life. Some other key patent filers include General Electric , Xyleco , Kawasaki Heavy Industries , Energy Dome , Emerson Electric , IHI .

In terms of application diversity, Xyleco leads the pack. Tenneco and Hitachi stood in the second and third positions, respectively. By means of geographic reach, Xyleco held the top position, followed by Energy Dome and Hitachi .

To remove excess heat from the turbine, the engine operating temperature should be maintained for efficient functioning, and to bring the engine to the right operating temperature as quickly as possible, cooling system becomes the essential part of the power generation process and power plants.
