IEA calls for sixfold expansion of global energy storage capacity

The International Energy Agency (IEA) has issued its first report on the importance of battery energy storage technology in the energy transition. It has found that tripling renewable energy capacity by 2030 would require 1,500 GW of battery storage.

EcoFlow unveils air-to-water heat pump, PV-powered water heater

EcoFlow has launched a new air-to-water heat pump for residential applications. The new product, equipped with R290 refrigerant, is available in 9 kW and 20 kW versions.

CATL unveils first mass-producible battery storage with zero degradation

China-based Contemporary Amperex Technology Co. (CATL) has launched its new TENER energy storage product, which it describes as the world’s first mass-producible 6.25 MWh storage system, with zero degradation in the first five years of use.

How safe are LFP batteries?

Researchers found that nickel manganese cobalt (NMC) batteries generate larger specific off-gas volumes, while lithium iron phosphate (LFP) batteries are a greater flammability hazard and show greater toxicity, depending on relative state of charge.

Tesla reports record energy storage deployment figures

Tesla’s electric vehicle (EV) sales are plummeting, but its energy storage business is surging, with more than 4 GWh deployed in the first quarter of 2024 alone.

Iron-based redox flow battery for grid-scale storage

Researchers in the U.S. have repurposed a commonplace chemical used in water treatment facilities to develop an all-liquid, iron-based redox flow battery for large-scale energy storage. Their lab-scale battery exhibited strong cycling stability over one thousand consecutive charging cycles, while maintaining 98.7% of its original capacity.

Sodium-ion batteries – a viable alternative to lithium?

While lithium ion battery prices are falling again, interest in sodium ion (Na-ion) energy storage has not waned. With a global ramp-up of cell manufacturing capacity under way, it remains unclear whether this promising technology can tip the scales on supply and demand. Marija Maisch reports.

Evaluating the profitability of vanadium flow batteries

Researchers in Italy have estimated the profitability of future vanadium redox flow batteries based on real device and market parameters and found that market evolutions are heading to much more competitive systems, with capital costs down to €260/kWh at a storage duration of 10 hours.

Next-gen battery trends

Lithium ion is the industry standard for a reason. Marija Maisch examines the most promising technological advances that could lead to further improvements in performance and cost from this versatile battery chemistry.
