Mar 11, 2026 - Gravity Batteries: Storing Renewable Energy Underground?! Renewable energy is the cheapest power source on Earth, but we need a way to store it for when the sun sets and the wind stops. While most focus on chemical batteries, Green Gravity is looking "from the ground down" at the power of gravity. In this episode of the Everything Electric Tech Show, we visit a massive industrial site in Australia to witness a revolutionary storage system. By repurposing millions of abandoned mine shafts, this technology turns heavy weights into "mechanical batteries." Using excess solar or wind power, massive weights are lifted to the top of a deep shaft. When the grid needs electricity, those weights are lowered to spin a regenerative motor. This mechanical system boasts an impressive 80% efficiency and offers long-duration storage of up to 24 hours, far exceeding standard lithium-ion limits. With 96,000 legacy mines in Australia alone, Green Gravity is utilising "latent assets" that already have existing grid connections. Join Robert as he explores the Gravity Lab to see the pilot in action before it launches at megawatt-scale.
