Switzerland is building the world's most powerful redox flow battery

A construction team in Switzerland is excavating a hole in the ground that'll end up being over 88 ft deep, and spanning the length of two soccer pitches. This pit will be home to the country's first redox flow battery for storing clean energy.

Candle compound brings high density to grid-scale battery technology

There is still some work to do in bringing current redox flow battery designs up to speed in terms of both performance and sustainability, but a new approach tackles the problem on both these fronts, by drawing on a compound commonly found in candles.

Scientists build first redox flow battery made of all-organic materials

As a storage solution for renewable energy, scientists see great potential in what are known as redox flow batteries. A new design from Linköping University is a decidedly green version of this, being the first made from all-natural materials.

Robo-fish is powered by blood-like battery fluid

A team of engineers at Cornell has built a robotic fish powered by electric blood, which not only serves as an energy source, but acts hydraulically to create propulsion as well. This bio-inspired approach addresses one of the great challenges for small, untethered robots – mass vs. power.

World's largest redox flow battery being built in underground salt caverns

Just last week, Tesla announced it was building the world’s largest lithium-ion battery in Australia. Now a German energy company, Ewe Gasspeicher GmbH, is building a redox flow battery in underground salt caverns with enough output to supply a day’s worth of power to 75,000 homes.

A new flow battery technology is expected to cost substantially less and be better for the environment thanks to its organic water-based electrolytes, as seen here in a small demonstration by PNNL researcher Xiaoliang Wei

New flow battery projected to cost 60% less than existing standard

A new flow battery technology promises to drastically lower the cost and sustainability of running energy storage systems. The battery uses low-cost and sustainable organic materials for electrolytes rather than the usual commodity metals, and it could be retrofitted to existing batteries.

Researchers have, for the first time, found a way to store electrons generated by photoelectrochemical (PEC) cells for long periods of time
