CMBlu Energy’s organic flow batteries to be tested in microgrids, cold climates

The U.S. Department of Energy’s Argonne National Laboratory and Idaho National Laboratory will carry out demonstration projects to validate long-duration energy storage tech developed by German manufacturer CMBlu Energy. The collaborative project is designed to improve microgrids in cold climates and make fast charging of electric vehicles more affordable in underserved communities.

Gates-backed Fourth Power pilots thermal storage based on TPV cells

Fourth Power, backed by Bill Gates’ venture firm, has developed high-density thermal energy storage based on thermophotovoltaic cells. The tech, which is reportedly 10 times cheaper than lithium-ion batteries, is based on the U.S. company’s patented liquid metal heat transfer system.

Transformer shortages: New bottleneck of the energy storage supply chain

Transformer shortages are taking their toll on battery energy storage system (BESS) integrators, as competition in the market intensifies.

New opportunities for 4-hour-plus energy storage

Energy storage with more than four hours of duration could assume a key role in integrating renewable energy into the U.S. power grid on the back of a potential shift to net winter demand peaks, says the National Renewable Energy Laboratory (NREL).

Anode-less redox flow batteries capable of fast cycling

Researchers in the US have demonstrated that replacing the planar lithium anode in a redox mediated lithium-sulfur redox flow battery with a high surface area scaffold enables 10 times faster cycling, up to 10 mA cm−2, without short circuit or voltage instability.

Carbon-cement supercapacitors for bulk energy storage

The Massachusetts Institute of Technology (MIT) has developed a scalable bulk energy storage solution with chemical with inexpensive, abundant precursors: cement, water, and carbon black. Their supercapacitors have high storage capacity, high-rate charge-discharge capabilities, and structural strength.

Solid-state lithium-ion batteries based on foil-based negative electrodes

Georgia Institute of Technology researchers used aluminum foil-based negative electrodes with engineered microstructures in an all-solid-state lithium-ion cell configuration. They have reported hundreds of stable cycles with practically relevant areal capacities at high current densities.

Separator tech to prevent battery fires

Nuvola Technology says it has developed a direct deposition polymer separator technology that can eliminate the primary cause of lithium-ion battery fires.

First Solar acquires perovskite specialist Evolar

First Solar has agreed to pay $38 million to buy Swedish manufacturing startup Evolar AB, as it seeks to expand development of high-efficiency tandem PV tech.
