Energy enabling technologies

Over 30% of clean energy international patent families (IPFs) come from energy enabling technologies. They are critical to unlocking the full potential of clean energy systems.

Energy storage solutions, such as advanced batteries, help balance supply and demand by storing excess renewable power for use when generation is low. Smart grids enhance the reliability and efficiency of electricity distribution, optimising the integration of variable sources like wind and solar. Hydrogen, especially when produced using renewable electricity, offers a flexible, low-carbon energy carrier for hard-to-decarbonize sectors. Continuous innovation in these technologies is essential to creating a stable, resilient and fully decarbonized energy infrastructure.

Q&A – Insights from the EPO

Are enabling technologies really that important for the energy transition?

Yes, they are. You could even say that they oil the wheels of the energy transition. While renewable energy technologies are maturing and finding their way into the energy mix, the main driver of low-carbon energy growth since 2017 has been innovation in cross-cutting technologies such as batteries, hydrogen and smart grids, as well as carbon capture, utilisation and storage (CCUS) that serve as key enablers of the energy transition.

As shown in the graph below, low-carbon energy innovation is shifting from supply to end-use and enabling technologies.

Which regions lead in electrolyser patents and how are they divided by technology type?

Patenting trends in five main sub-technology areas have been identified. These areas are cell operation conditions and structure, electrocatalyst materials, separators (diaphragms, membranes), stackability of electrolysers (stacks) and photoelectrolysis.

As can be seen in the graph, Europe and Japan are the leading filers of international patent families in all five areas.

Which companies are the most important filers for patents in battery technology?

As illustrated by the graph below, the patent landscape changed slightly with the advent of electric vehicles, which saw car (part) manufacturers enter the field.

Nowadays the most important filers of international patent families in battery technologies are mainly Japanese and Korean large electronics and car manufacturers.

Are “smart grids” getting even smarter?

Artificial intelligence (AI) is gaining a lot of traction in smart grid innovation. AI patenting grew by over 500% in the five years to 2022 and is now the most active area of patenting among enabling digital technologies, led by the United States and P.R. China.

The main area of AI-related IPFs is the “forecast and decision” category which boasts 39% of AI-related international patent families and drove rapid growth in AI-related electricity grid patenting from 2000 to 2022.
