EU battery capacity doubled in a year as solar added more than 90 GW
The EU summer outlook links rapid solar growth with a doubling of installed battery capacity and a growing need for flexible electrical and thermal loads.
-
LFP now powers about 90% of new stationary batteries — what that changes for buyers
Global battery deployment accelerated again in 2025, while lithium iron phosphate became the dominant stationary chemistry. Here is what the shift means when comparing a real storage system.
-
Batteries, renewables and flexible consumption must grow together in Czechia
AKU-BAT’s example shows why generation, batteries and controllable consumption should be planned as one system.
-
Water heaters and thermal stores are becoming grid-flexibility assets
Flexible demand is no longer limited to factories. Water heating, storage heating and controlled thermal loads can absorb electricity when supply is abundant and release useful heat later.
-
Most new Czech home solar systems already include batteries; thermal storage is the next opportunity
A Czech study reports that 84% of newly installed home solar systems included batteries and identifies heat as another practical destination for renewable surplus.
-
Storage can unlock grid capacity before a new power line is built
More than 2,500 GW of projects are waiting in grid queues worldwide. The IEA shows how batteries, flexible connections and grid-enhancing technologies can release capacity sooner.
-
Energy storage now represents 40% of energy patenting — but buyers still need proven systems
Battery inventions account for an unprecedented share of energy patents. Innovation is accelerating, while compatibility, documentation and service remain decisive for a real installation.
