Gravitricity: Fast, Versatile Energy Storage Solution: UK

Globally, we are generating more electricity from intermittent renewable energy sources than ever before. We are slowly making steps to a decarbonized world, but for our renewable energy, we are still reliant on weather-dependent sources, like marine, wind, and solar. We will need new technologies to capture and store energy during periods of low demand and with a quick release when needed. The idea of the British start-up Gravitricity almost seems too good to be true. By using enormous weights, the company wants to turn mine shafts into low-cost energy storage systems – with 'some of the best characteristics of lithium batteries and pumped storage.' Is this the large-scale electricity storage the world needs, or is it, in fact, too good to be true?

The concept seems to be so simple. Gravitricity describes their innovative technology as a huge 'clock weight.' "A cylindrical weight of 500 - 5000 tonnes is suspended in a deep (preferably already existing) 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."

Gravitricity: Fast, Versatile Energy Storage Solution Like A Dream

The target groups are network-constrained users and operators, distribution networks, and major power users. The technology operates in the 1MW to 20 MW power range. With a design life of fifty years, response time from zero to full power in less than one second and efficiency between 80 and 90 percent, Gravitricity seems like a dream. It is a way to utilize existing mines or purpose-built shafts. ‘Future deployments will be able to utilize existing mines or purpose-built shafts, allowing development wherever storage is required,’ according to Gravitricity. And there is more: the start-up claims levelized costs well below lithium batteries.

For all the above reasons, Gravitricity already has its fanbase. The company received an Innovate UK (the government’s innovation agency) funding of 650.000 pounds to start on its prototype. Also, Gravitricity is teaming up with the well-respected Dutch winch and offshore manufacturer Huisman Equipment BV. ‘The first full-scale prototype will be deployed in 2021 or 2022 at a disused mine in the UK,’ the start-up reveals.

According to the Bloomberg New Energy Finance's Global Energy Outlook 2018 – the annual economic forecast for the world's power mix to 2050 –there will be '$600 billion of global spend on energy storage to 2040. ' Gravitricity 's goal is to '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,' as they write on their website.

What do you think: will Gravitricity enable existing grid infrastructure to go further in a renewable energy world by providing this essential energy storage?
