Grid-Scale
We’re solving grid flexibility challenges
Energy intensive businesses urgently need the flexibility to store and shift energy – at scale. That’s where we come in. We are working towards a new grid-scale solution based on our PRISMA Advanced Liquid Air Energy Storage (LAES) technology. It has been adapted and scaled up to act as a long-duration energy store that can charge and discharge multiple times a day.
We have the answers.
Electricity grids around the world are beginning to feel the strain of rising demand. The transition to variable renewable energy sources is essential for decarbonisation, but it makes power systems more complex to manage due to their intermittency. PRISMA is the answer.
How it works
- During periods of low demand, PRISMA takes excess electricity (either from the grid or onsite renewables), and uses it to convert ambient air into cold, liquefied air. The compact liquid air can be stored in huge volumes in a vacuum insulated tank.
- During peak electricity demand (when more power is needed), the liquid air is transformed back into a gas. This gas drives a turbine, producing the required electricity at speed.
- PRISMA turns stored energy into power when it’s most needed. This flexibility makes it ideal for supporting data centres and other high-energy industries as they balance increasing energy demands with the need to decarbonise.
PRISMA: A sustainable alternative
to lithium-ion batteries
Compressed air generation is a major energy consumer, accounting for around 10% of all industrial electricity use in the UK. With rising energy costs and increasing pressure to decarbonise, it’s critical to optimise your compressed air systems now.
20 years+ product life
Suitable for extended storage periods - from 8-100hrs+
More sustainable - no disposal issues

FAQs
Still got questions? We’ve got the answers!
How is PRISMA connected to the Grid-Scale technology?
PRISMA is the key technology that has been developed into a grid-scale offer. So, we started with PRISMA, which offers industrial behind-the-meter energy storage. We developed and scaled that technology for a new purpose.
How does Grid-Scale compare to battery storage in terms of longevity and performance?
Grid-Scale is more suited to long-duration energy storage (8-10+ hours), whereas lithium-ion batteries are generally optimised for shorter durations (up to 4 hours). Grid-Scale has lower degradation over time and less environmental impact, making it safer.
What are the key benefits of Grid-Scale?
Our grid-scale solution supports clean power for 2030 and ambitions for net zero by 2050, including elements of industrial plans such as contracts for difference.
Most businesses have to pay for renewable generation and storage as a service. Our technology enables users to have grid-flexibility, and if they have on-site renewables, they have the potential to not only save carbon but also to significantly reduce their energy costs.
Which industries are most suited to Grid-Scale?
Heavy industry and high-energy usage sectors are ideally suited to our Grid-Scale solution due to their substantial storage and energy management needs.

- Data centres
- Mining
- Cement industry
- Large manufacturing plants
