The power industry continues to be a hotbed of innovation, with activity driven by increasing demand for energy storage solutions and balancing energy demand and supply, and growing importance of technologies such as organic PCMs, inorganic, hygroscopic materials, and solid-solid PCMs. 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 Environment Sustainability in Power: PCM Thermal Energy Storage.
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 stabilising 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.
90+ 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 83,000 patents, there are 90+ innovation areas that will shape the future of the industry.
Within the emerging innovation stage, smart lighting system, PCM thermal energy storage and solid electrolyte fuel cell membrane are disruptive technologies that are in the early stages of application and should be tracked closely. Ceramic oxide nuclear fuel, geothermal heat pumps, and hybrid PV plants are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are combined-cycle gas turbines and ethylene co-polymer PV modules, which are now well established in the industry.
Innovation S-curve for environmental sustainability in the power industry
PCM thermal energy storage is a key innovation area in environmental sustainability
Thermal energy storage through the phase change material (PCM) can store and release large amounts of energy. To retain and release energy, the system depends on the shift in phase of the material. For example, processes such as solidifying, melting or evaporation require energy.
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 PCM thermal energy storage.
Key players in PCM thermal energy storage – 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’.
