How to Run Underground Power to a Shed
As the world generates more and more electricity from intermittent renewable energy sources, there is a growing need for technologies which can capture and store energy during periods of low demand and release it rapidly when required.
At Gravitricity we are developing a novel storage technology which offers some of the best characteristics of lithium batteries and pumped storage. Ideally suited to network-constrained users and operators, distribution networks and major power users, the technology operates in the 1MW to 20 MW power range and enables existing grid infrastructure to go further in a renewable energy world.
Gravitricity are truly grateful for the support and are now all set to commence fabrication of our proof of concept demonstrator. If you would like to keep up to date with our progress and any future funding rounds, please sign-up here to our company newsletter. Our patented technology is based on a simple principle: raising and lowering a heavy weight to store and release energy.
The Gravitricity system suspends weights of - tonnes in a deep shaft by a number of cables, each of which is engaged with a winch capable of lifting its share of the weight. Electrical power is then absorbed or generated by raising or lowering the weight.
The weight is guided by a system of tensioned guide wires patents applied for to prevent it from swinging and damaging the shaft. The winch system can be accurately controlled through the electrical drives to keep the weight stable in the hole. Each unit can be configured to produce between 1 and 20MW peak power, with output duration from 15 minutes to 8 hours.
The key requirement is a deep hole in the ground; it can be a disused mineshaft brought back into use, or a purpose-sunk shaft. Shaft depths can be from m for new shafts down to m for existing mines. The grid connection is through modern power electronics to permit rapid switching between generation and absorption of power and the system can deliver active as well as reactive power to help with grid stability.
The ground provides the bursting resistance other than at the very top of the shaft. The winches and generators will be contained in the pressurized space so that only electrical cables need to penetrate the pressure vessel walls. Initially we will prove the technology using existing mine shafts. We are working with Dutch winch and offshore manufacturer Huisman Equipment BV and are developing an Industrial Consortium to take the technology to market. Huisman was originally founded in as a steel construction company and now has the capacity to develop products from concept to delivery.
Their product range can be subdivided into four main categories: Heavy Lifting Equipment, Drilling Equipment, Pipelay Equipment and Mooring Systems and varies from stand-alone components to highly engineered integrated systems.
Our technology will provide balancing services on transmission grids as well as appealing to network-constrained users and generators, distribution networks and major power users seeking a reliable, fast response, and long-term means of storing power. The Gravitricity technology is inherently durable and flexible. It can also be sited at locations where energy storage is particularly required: on constrained distribution grids, behind customer meters, and on micro-grids where the technology can provide long-term system balancing.
On existing grids Gravitricity installations can be considered as long term infrastructure assets that maximise the utility of existing grid hardware. In many situations they can be deployed to minimise or remove altogether the requirement for expensive distribution grid upgrades as demand and supply patterns change. On emerging grids, Gravitricity systems will significantly reduce the requirement for redundancy in grid hardware.
There is very significant opportunity to reduce the cost of rural electrification across the developing world by deploying long-life storage technologies. Martin Wright, Chairman, has a background in entrepreneurial company development eg.

Imperial College Analsysis suggests early Gravitricity projects will be cheaper than lithium for frequency response applications. Gravitricity's first-of-a-kind 4MW prototype system will be cheaper than batteries on a levelised cost of storage basis.
The modelling emphasizes the importance of long life and lack of degradation for revenue stacking. Please contact Gravitricity by email if you would like a copy of the report.
REA shortlist here. Scottish Renewables Shortlist here. Gravitricity teams up with worldwide lifting, drilling and subsea specialists Huisman to build prototype energy store. Dutch-based Huisman Equipment BV are a perfect winch partner for Gravitricity and form the centre-piece of the Industrail Consortium being built to take the technology to market. They will supply winch-drive modules for the 4MW full-scale prototype planned for , and future systems.
This innovation funding will be used to design and build our kW concept demonstrator, ready for testing in late It will confirm Gravitricity's commercial characteristics, validate our simulations, and provide a physical proof-of-concept demonstration. Gravitricity is now raising seed funding to match the grant and would like to speak to potential investors, particularly those with power systems or mining experience. Gravitricity ltd has been selected for the prestigious Cleantech Innovate Investor Showcase in March Charlie Blair will be presenting details of the kW Concept Demonstrator and the associated investment proposition.
Lazards have published Version 3 of their Levelised Cost of Storage benchmarking analysis. This time the financial advisory firm have included capex and operating data from numerous new Lithium Ion batteries deployed since Version 1 in Both of these require high-power and rapid response and are of interest to Gravitricity.
Gravitricity has worked with experts from Imperial College London to understand how our storage costs compare. Our fast-response, multi-cycle technology is exceptionally well suited for any application requiring a high c-rate and several daily cycles. Gravitricity is working with Imperial College Storage Labs to understand how our costs compare to other technologies.
Results are very encouraging. He'll be speaking in the late morning session fittingly titled 'Scaling to GW; It's not just Lithium' along with speakers from flow-battery, CAES and electrolyser technology developers.

Before digging, call the utility locating service to mark any underground pipes or wires. Begin by digging a trench from the house to the shed. This can be done with a trenching machine or a shovel. The trench should be 18 inches deep to bury electrical conduit according to code.
