The power industry continues to be a hotbed of innovation, with activity driven by a number of factors, including the need for higher efficiency, lower emissions, and improved reliability and growing importance of technologies such as evaporative cooling, passive cooling, and forced air cooling. 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: Gas turbine air cooling.

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 of the industry.

Gas turbine air cooling is a key innovation area in power

A gas turbine air cooling system cools the hot air that is generated by the turbine. The cooled air is then used to cool the engine, which in turn increases the efficiency of the turbine.

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 10+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of gas turbine air cooling.

Key players in gas turbine air cooling – 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’.

Mitsubishi Power is one of the leading patent filers in gas turbine air cooling. Mitsubishi Power and China’s Sepco 3 have been awarded a full turnkey contract with Aluminium Bahrain (ALBA ). Mitsubishi Power will supply the combined cycle power unit, which comprises of M701JAC gas turbine, an air-cooled version of J-series gas turbines and a steam turbine.

In terms of application diversity, Raytheon Technologies leads, followed by General Electric and Hitachi in the second and third positions, respectively. By means of geographic reach, Siemens , Kawasaki Heavy Industries , and Rolls-Royce are some of the leading patent filers in battery energy storage systems.
