Picture this: an energy storage system that laughs in the face of -40°C winters while charging faster than you can finish your morning coffee. Meet the Capess Graphene Supercapacitor Battery GTEM-48V7400-E – the Clark Kent of energy storage solutions turning into Superman across industries. Unlike traditional batteries that throw tantrums in extreme temperatures, this graphene-powered marvel maintains 80% capacity even when Jack Frost is working overtime.
When Siemens recently deployed these units in their Hamburg wind farm, they reduced energy spillage by 40% during peak gusts. How's that for putting Mother Nature's mood swings to good use?
Stackable modules that play nice with existing infrastructure? Check. Fire-resistant electrolytes that make safety inspectors actually smile? Double check. Tesla's Megapack might need to watch its back – our graphene gladiator offers 25C discharge rates that leave lithium-ion batteries gasping for breath.
Traditional batteries are the Usain Bolt of power – quick bursts then collapse. Supercapacitors? They're the ultra-marathoners. Combine both through hybrid configuration and you've got an Olympic decathlon champion. The GTEM-48V7400-E's secret sauce? Graphene's electron highway system that makes charge carriers feel like they're riding bullet trains.
Beijing's subway system doesn't trust just any battery for emergency lighting. After testing 15 alternatives, they standardized on Capess units. Why? Try 200,000 charge cycles without performance drop-off – that's like circling the globe 8 times without changing tires.
As renewable energy hits 35% of global grids, utilities are scrambling for storage that doesn't blink during cloudy days or calm nights. The GTEM series' 98% round-trip efficiency makes energy accountants do actual cartwheels (safety goggles recommended).
Remember when battery swaps required more tools than a NASA launch? Capess' modular design lets technicians hot-swap modules faster than a pit crew changes tires. Diagnostic LEDs that even your colorblind intern can understand? Now that's what we call engineering empathy.
Rumor has it Capess Labs is experimenting with self-healing nanocoatings – imagine batteries that repair minor damage like human skin. Pair that with wireless load balancing and we're looking at infrastructure so smart, it could probably get a PhD.
From data centers tired of playing thermal Jenga to electric ferries crossing the Norwegian Sea, the GTEM-48V7400-E isn't just another battery. It's the energy storage equivalent of teaching fish to ride bicycles – impossibly brilliant until you see it in action.

This report explores trends in battery storage capacity additions in the United States and describes the state of the market as of 2018, including information on applications, cost, ongoing trends,. . This report explores trends in battery storage capacity additions in the United States and describes the state of the market as of 2018, including information on applications, cost, ongoing trends,. . In this report, we provide data on trends in battery storage capacity installations in the United States through 2019, including information on installation size, type, location, applications, cost.

The remaining states have a total of around of 3.5 GW of installed battery storage capacity. Planned and currently operational U.S. utility-scale battery capacity totaled around 16 GW at the end of 2023. Developers plan to add another 15 GW in 2024 and around 9 GW in 2025, according to our latest Preliminary Monthly Electric Generator Inventory.
Two states with rapidly growing wind and solar generating fleets account for the bulk of the capacity additions. California has the most installed battery storage capacity of any state, with 7.3 GW, followed by Texas with 3.2 GW.
This report focuses on battery storage technologies, although other energy storage technologies are addressed in the appendix. Electrical, thermal, mechanical, and electrochemical technologies can be used to store energy. The capacity of battery storage is measured in two ways: power capacity and energy capacity.
