How water batteries can bank energy when wind, solar fail

Pumped storage hydropower has been in use for decades, but it's only recently that climate crisis is prompting a renewed interest in how power can be generated from renewable resources, wind and solar , placing a surmountable pressure on the industry. While expensive giant versions of the lithium-ion batteries are being deployed to store the intermittent output, it has yet to be commercialised and made more easily accessible. Pumped hydropower storage has, in comparison, already arrived supplying almost 90% of grid storage. It banks excess electricity when demand is low, particularly during the night, storing it as gravitational potential energy in the summit lake. Leading the world in renewable energy, China leads in pumped storage, with 66 new plants under construction, according to Global Energy Monitor. The Fengning plant near Beijing currently under construction, is set to become the world's largest with 12 turbines that can generate 3600 megawatts, and energy storage,...

SpaceX rocket sends first global water survey mission into orbit

LOS ANGELES:  A SpaceX rocket blasted off early on Friday carrying a US-French satellite designed to conduct an unprecedented global survey of Earth's surface waters, a mission expected to shed new light on the mechanics and consequences of climate change. The Falcon 9 booster owned and operated by Elon Musk's commercial rocket company lit up the predawn sky along California's coast as it roared off its launch pad at the Vandenberg US Space Force Base, about 160 miles (260 km) northwest of Los Angeles. The liftoff, directed by NASA, was shown live on a US space agency webcast. The Falcon 9's upper stage, carrying the satellite, reached orbit within nine minutes. Moments earlier, the reusable lower stage separated from the rocket and flew itself back to Earth, unleashing sonic booms before slowing to a gentle landing at the base. The mission's payload, the Surface Water and Ocean Topography satellite, or SWOT, was released to its own starting orbit ...
