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.

45+ 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 45+ innovation areas that will shape the future of the industry.

Within the emerging innovation stage, solar-powered desalination, wind turbine performance monitoring, and renewable energy storage are disruptive technologies that are in the early stages of application and should be tracked closely. Foldable solar panels, solar thermal collectors, and geothermal collectors are some of the accelerating innovation areas, where adoption has been steadily increasing. Among maturing innovation areas are wave energy converters and solar cell protective films, which are now well established in the industry.

Innovation S-curve for environmental sustainability in the power industry

Solar thermal collectors is a key innovation area in environmental sustainability

A solar thermal collector is a device in which solar energy is collected by absorbing solar radiation in an absorber and then transferring that heat to a medium (water, solar fluid, or air). Solar thermal collectors are either concentrating or non-concentrating.

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 170+ companies, spanning technology vendors, established power companies, and up-and-coming start-ups engaged in the development and application of solar thermal collectors.

Key players in solar thermal collectors – 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’.

Patent volumes related to solar thermal collectors

GlassPoint Solar is one of the leading patent filers for solar thermal collectors. The New York-based company intends to deliver the lowest-cost solar steam to power industrial processes and has been delivering solar process steam in commercial quantities since 2012 through its enclosed trough technology. It has been developing and improving this technology over the last ten years, resulting in a portfolio of 100 issued and pending patents. More than 60 percent of installed base of solar process steam in the world uses GlassPoint’s enclosed trough technology. GlassPoint Solar signed a memorandum of understanding with Saudi Arabia’s leading mining company Ma’aden in June 2022 to develop the world’s largest solar process steam plant.

Another leading patent filer, Brenmiller Energy, offers sustainable thermal energy storage solutions and has developed bGen™, a patented high-temperature thermal energy storage technology based on storing heat using crushed volcanic rocks. It launched the next generation thermal storage technology, bGen™ ZERO, in August 2023.

In terms of application diversity, Flex leads the pack, while BASF and W&E International Canada stood in the second and third positions, respectively. By means of geographic reach, Drift Marketplace held the top position, followed by Flex and Magaldi Group.
