Green Gravitational Storage with Mark Swinnerton
Whilst working as Vice President of Market Analysis for BHP, Mark realised it was really difficult to see how net zero climate scenarios were going to happen, but that these solutions were necessary to limit climate impacts. This shifted him onto a new path of thinking of “what more could be done, what do people need to stand up and find out and make happen over the coming years”.
Mark left BHP keen to activate something big to prove we can have our low-carbon solutions and our economy at the same time. Green Gravity will be instrumental in providing an opportunity for the next economic life of the very many disused mine shafts across the globe.
The sustainable solution will revive these vertical shafts and take advantage of their height to raise weighted steel objects with renewable energy, store these weights at the surface, and then use gravity to spin a turbine as these are lowered back down the shaft to generate electricity, to be directed straight into the grid when it is needed.
The Green Gravity team and its partners are working from flexible locations around the world, based at the Innovation Campus in Wollongong, helping industry gravitate towards a clean energy future.
We need to be able to add a lot more storage both in Australia and globally. We need those new solutions and that’s where gravitational energy comes into its own, and where it can start to have a huge impact where it actually improves the economics of the transition to renewable energy faster. Mark Swinnerton, CEO, Green Gravity.
