In a new interview with Energy Synapse, Sara Taylor, Hydrostor’s Senior Director of Government and Regulatory Affairs, shares how Advanced Compressed Air Energy Storage (A-CAES) can provide dependable, cost-effective power using proven mechanical systems. Sara explains how A-CAES can be developed in a wide range of geological settings, while using significantly less land and water than other large-scale storage options. The discussion also highlights the role A-CAES can play in strengthening Australia’s grid and supporting new investment in reliable infrastructure.

A single 500 MW A-CAES facility can power up to 400,000 homes for eight hours, nearly a third of San Diego. That’s the scale of Hydrostor’s Willow Rock Energy Storage Center in Kern County, California. Using air, water, and rock, our Advanced-Compressed Air Energy Storage technology delivers reliable, long-duration power with no fuel and no emissions. Projects like Willow Rock show what practical innovation looks like. They strengthen the grid, support local jobs, and advance true energy independence.

Hydrostor teams were on the ground last week at Heatmap News Climate Week NYC, Energy Storage Canada 2025, and the National Clean Energy Week shaping the future of energy. Electrification, AI, and industrial growth are driving unprecedented demand for energy storage. But this moment calls for more than quick fixes, it demands a bold rethink of how we plan, build, and scale solutions. Hydrostor’s Advanced Compressed Air Energy Storage is proven, scalable, and ready to anchor the grid for decades to come. #EnergyStorage #LDES #Hydrostor #Innovation #Infrastructure
