With real uncertainty clouding the world’s supply of lithium, alternative battery chemistries will be crucial as we continue our uptake of electric vehicles and mobile devices. One exciting candidate in this space is sodium-ion, and a research team in … Continue reading Powdered sodium battery design promises a 15% leap in energy density
Wave Swell Energy’s remarkable UniWave 200 is a sea platform that uses an artificial blowhole formation to create air pressure changes that drive a turbine and feed energy back to shore. After a year of testing, the company reports excellent results.Co… Continue reading Blowhole wave energy generator exceeds expectations in 12-month test
Wind and solar power are intermittent, generating power when it’s available rather than when it’s needed, so the green energy transition will require huge amounts of energy storage. This could end up taking many forms, from conventional lithium-based “… Continue reading World’s first commercial sand battery begins energy storage in Finland
Perovskite is poised to become a major material for solar cells, but before then it needs to overcome a major durability issue. Engineers at Princeton have unveiled a new perovskite solar cell design that tests suggest could last as long as 30 years of… Continue reading First perovskite solar cell to cross 30-year expected lifespan
Solar cells are an increasingly important source of renewable energy, but there’s still room for improvement. Stanford engineers have now developed a pyramid-shaped lens that can focus sunlight from any angle onto a solar cell, keeping it collecting po… Continue reading Pyramid lenses catch light from any angle to boost solar cell efficiency
Michigan energy systems company Sesame Solar announced this week what it calls the world’s first 100-percent renewable mobile nanogrid. Powered by both its wing-like solar panel spread and green hydrogen, the next-generation modular nanogrid gets trans… Continue reading Fast-deploying solar/hydrogen nanogrid wheels emergency power off-grid
In many ways, space is the perfect place for a solar energy array. There are no clouds in the way, no seasonal variability, no atmospheric filtering, and your solar panels can operate at peak efficiency around the clock, since the planet doesn’t block … Continue reading China tests world-first full-function space solar verification tower
Italian company Energy Dome has opened the first of its remarkable grid-level energy storage plants. These “CO2 batteries” can store renewable energy over long periods and release it quickly, at less than half the cost of big lithium batteries.Continue… Continue reading Energy Dome launches world’s first CO2 battery energy storage facility
Renewable energy is intermittent, so energy storage and release will be critical in the next few decades. IIASA researchers have put forth a fascinating solution, proposing to turn skyscrapers into giant gravity batteries for remarkably cheap renewable… Continue reading Lift Energy Storage System: Turning skyscrapers into gravity batteries
Researchers at the National Renewable Energy Laboratory (NREL) have broken the world record for solar cell efficiency. Reaching almost 40 percent, the new device boasts the highest efficiency recorded for any type of solar cell in real-world conditions.
