The power industry continues to be a hotbed of innovation, with activity driven by the need for greater renewable power generation and battery storage and improved grid reliability, and growing importance of technologies such as lithium-ion batteries, lithium iron phosphate batteries, lead-acid batteries, and sodium-based batteries. 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 Cybersecurity in Power: Battery energy storage system (BESS).
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.
Battery energy storage system (BESS) is a key innovation area in cybersecurity
Battery energy storage system devices are used widely for storing energy intended for later usage. Energy storage is a mechanism of improving flexibility and maximising the efficiency of the power grid. The application of energy storage is to provide services such as frequency regulation, load shifting, black start and ramping up.
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 30+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of battery energy storage system (BESS).
Key players in battery energy storage system (BESS) – 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’.
