New Idea To Turn Abandoned Mines Into Batteries

February 9, 2023 | Leave a Comment

Open Image…Save ImageOpen Image (using #TmpD/ia)… The International Institute for Applied Systems Analysis (IIASA) has offered a new technique called Underground Gravity Energy Storage that turns decommissioned mines into long-term energy storage solutions. Renewable energy sources are central to the energy transition toward a more sustainable future. However, as sources like sunshine and wind are inherently variable and inconsistent, finding […]

Gravity Is Back In Energy Storage In A Very Different Way

January 11, 2022 | Leave a Comment

The puzzle that bedevils renewables in electrification is storage. We usually think of batteries as the obvious solution and that is an excellent answer in small quantities and short periods of time. The problem lies in renewables needing daylight or wind to generate power and when the base energy source sets or dies down the […]

Can Pumped Hydro Systems Work At Small Scale?

October 27, 2016 | 19 Comments

Université Libre de Bruxelles School of Engineering researchers are investigating whether energy storage via pumped hydro systems is possible on a very small scale, particularly in buildings. The team used the Goudemand apartment building in Arras in France as their case study for Pumped Hydro Energy Storage (PHES). So far pumped-storage hydroelectricity systems are to […]

Almost Free Energy That Might Work Out

May 28, 2015 | 38 Comments

There is a new energy generating idea based on floating the buckets of a bucket elevator running backwards in a column of water. Its almost that simple. Add an air compressor to blow the water out of the buckets for the ride up and a generator connected to one of the elevator shafts and you […]

Energy From Simply Trying to Float

May 30, 2012 | 5 Comments

Here’s the at home test, push a plastic cup that’s upside down into water.  Gravity working on the mass of the displaced water is trying to push the cup back up, that’s buoyancy.  Simple enough, and there is a wealth of places to do this, wells, ponds, lakes, standpipes, water heaters, anywhere that gravity can […]
