Read the latest positive news, breakthroughs, and inspiring stories about clean energy storage, curated daily by BrightWire.
Scientists in Germany have cracked a major code in battery technology, creating cells that last over 1,000 charging cycles while keeping most of their power. This breakthrough could make electric cars cheaper and help store renewable energy more efficiently.
A Bangalore company has created iron-air batteries that can hold renewable energy for up to four days, solving one of the biggest challenges facing solar and wind power. Using just iron, air, and water, the technology could make clean energy grids work even during windless, cloudy weeks.
Scientists discovered that iron powder can store renewable energy for months and work in converted coal plants. This breakthrough could make wind and solar power available worldwide without building massive new infrastructure.
Chinese automaker BYD is developing sodium batteries so cheap and durable they could revolutionize how the world stores renewable energy. At just 4 cents per watt-hour, these batteries could last over three decades in power grids.
A Canadian company turned solid bedrock 2,000 feet underground into a massive mechanical battery that stores clean energy for decades. The technology sidesteps the environmental problems of lithium batteries entirely.
Scientists created a water-based battery that could safely store renewable energy for years without catching fire. The zinc-manganese battery overcomes a major problem that has plagued clean energy storage.
A Slovenian engineering firm just landed the contract to build Norway's biggest pumped-storage hydropower plant, turning mountains into a massive renewable energy battery. The €220 million project proves small countries can drive Europe's green energy future.
