The world needs zero carbon energy. now.
Solar produces energy when the sun shines, not always when it is needed.
Intermittent renewables need storage
Challenge
Intermittent Generation
Renewables such as wind and solar are intermittent, producing energy when the wind blows and the sun shines. This means that the production of decarbonised energy does not match with the demand for that energy.
Green Gravity solution
Storing renewable energy for use at peak times
Storage allows power producers and consumers to smooth production and demand. This allows renewable energy to be time shifted to when it is needed the most, reducing its cost and ultimately accelerating the shift away from coal.
Challenges of the current storage options
Pumped hydroelectricity is large and cheap but uses lots of water and land.
Lithium batteries are flexible but they are 100% imported, have short life, have low recycling levels and can catch on fire. Other options include chemical flow batteries which are experimental and compressed or liquid air using large investment in complex machines.
Our technology provides low-cost, flexible and ultra-green energy storage.
Circular
Driving circular economic value by reusing old mine shafts to support green energy.
Flexible
Provides short or mid duration storage or grid ancillary services.
Sustainable
Low noise, small land use, no water, chemicals, or destruction of farmland. Our technology can be fully recycled, unlike battery options.
Local
Locally sourced materials, supply chain and workforce create economic value in the local community.
Low-cost
Offering attractive economics due to reuse of infrastructure, high efficiency, low operating and maintenance costs and long life of the asset.
Long Life
Our system does not degrade, meaning we invest once to match long run energy security needs, avoiding the costly performance degradation of batteries.
Our technology will drive serious, economic, decarbonisation. now
