The International Energy Agency (IEA) published a revealing report on February 17, 2026, that we link to below. In it, they motivate how batteries are in a security-focused phase supporting distribution grid reliability.
The IEA confirms that globally we are entering a new energy transition. The organization defines the focus points as ‘energy security, industrial competitiveness, and infrastructure resilience’.
Proof That Batteries Are In a Security Phase
The IEA cites impressive evidence of how batteries entered a security-focused phase:
- Energy technologies have become multi-trillion dollar global markets.
- Some one-in-ten patents worldwide relate to new energy technologies.
- This is greater than those for chemicals, pharmaceuticals,or transport.
- These trends underline the sector’s role in national and industrial strategy.
But that’s not all. The IEA has identified over 150 major innovations during 2025. These include solid-state air conditioning, perovskite solar cells, fusion energy, sodium-ion batteries, and next-gen geothermal systems.
But there’s still more to come. Energy security emerged as a leading driver in 2025. This puts security ahead of affordability and emission control. Leading economies are reinforcing their technical competencies, and securing critical material supply chains too.
Public Support Growing For Energy Storage Batteries
Energy storage now commands a leading role among global innovations. This further highlights the role of batteries in national security and power systems. Batteries are firmly in a security-focused phase now, having seized a 40% share of all 2023 patents.
Our blog reflects this trend as we report regularly on revolutionary discoveries in research laboratories worldwide. Some of these new battery technologies will fall by the wayside. Others will eventually find their way via patents to the marketplace.
There is solid proof of this, in one more astounding IEA revelation. Batteries accounted for 40% of all energy patents in 2023. This trend continued through 2024 and 2025, based on preliminary data. We believe there will be more to come …
