Faceți loc litiului: bateriile cu aluminiu și sulf declanșează o revoluție energetică

In January 2024, a study in Nature Communications reported an aluminum-sulfur battery retaining 85.4% capacity after 1,400 cycles at 85°C. In October 2024, Lyten announced plans for the world’s first Li–S battery gigafactory in Nevada, aiming for 10 GWh/year by 2027. In 2023, Phinergy and Indian Oil unveiled India’s first aluminum-air battery vehicle. Laboratory Li–S cells have reached 400–500 Wh/kg.

Revoluția Stocării Energiei din 2025: Baterii Revoluționare, Sisteme pe Bază de Gravitație și Hidrogenul care Alimentează Viitorul

Global battery storage capacity must reach 1,500 GW by 2030, a 15-fold jump, according to the IEA. Lithium-ion battery prices fell about 20% in 2024 to $115/kWh. The world’s largest vanadium flow battery, 175 MW/700 MWh, was completed in Ulanqab, China. CATL plans to launch second-generation sodium-ion batteries in 2025, targeting over 200 Wh/kg.

Revoluția stocării hidrogenului: Descoperirea verigii lipsă a energiei curate

NREL and GKN Hydrogen commissioned a 500 kg metal hydride hydrogen tank in Colorado, the first of its kind, at the end of 2024. Hydrogenious is building the world’s largest LOHC plant in Germany, set to open in 2027. Uniper began filling a salt cavern with hydrogen in Germany in September 2024. NASA tests in late 2024 showed new insulation cut hydrogen boil-off by about 50%.

Bateriile cu ioni de sodiu vin – mai ieftine, mai sigure și pregătite să perturbe pe cele cu ioni de litiu

China activated the world’s largest sodium-ion battery storage farm in July 2024, with 100 MWh capacity, developed by HiNa Battery and Datang. JAC began mass production of an electric car using sodium-ion batteries, while CATL plans to launch its next-generation sodium-ion cells by late 2025. Sodium-ion batteries offer lower raw material costs and improved safety but have 20–30% less energy density than lithium-ion.

Revoluția celulelor de combustie: Cum energia pe bază de hidrogen transformă transportul, energia și tehnologia în 2025

Over 70,000 hydrogen fuel cell forklifts operate daily in warehouses, with major fleets at Walmart and Amazon. Toyota Mirai, Hyundai Nexo, and Hyundai’s XCIENT trucks use PEM fuel cells, while Japan has tens of thousands of SOFC units in homes. Daimler Truck and Volvo formed Cellcentric for truck fuel cells. DMFCs power portable devices, but with lower efficiency than PEM.
