Sustainable Energy provides technical, financial, economic and commercial support for energy storage solutions, helping clients optimise the capture, storage, and use of heat and electricity across their sites and/or networks.
Our experience covers technical feasibility, detailed design, system integration, and performance analysis to ensure storage solutions deliver maximum efficiency, reliability, and commercial benefit.
Seasonal thermal storage
We design and assess seasonal thermal storage systems that capture heat and/or coolth for use months later, helping balance supply and demand across the year. Depending on site or network requirements, this can include underground borefields, large insulated water tanks, or engineered pit or aquifer storage. Benefits include maximising renewable heat use, reducing reliance on backup fuels, improving network efficiency, and lowering operational costs.
Our services cover sizing, system layout, integration with heat networks, and techno-economic analysis, helping clients choose the most effective storage solution for performance, cost, and long-term reliability.
Thermal pit storage
Pit storage offers cost-effective bulk energy storage, making it ideal for seasonal thermal applications where large volumes of heat need to be captured for later use. Compared to above-ground tanks, pits can store much larger volumes at lower cost, with lower heat losses and greater flexibility for network integration.
Sustainable Energy provides technical modelling support for large-scale thermal pit storage, including feasibility studies, design of insulated storage pits, and integration with district heating networks. We assess technology options, site-specific factors for space, ground conditions, and heat recovery potential. Our approach ensures practical, efficient solutions that maximise renewable heat utilisation and network performance.
Modelling energy storage
The characteristics of different charge and discharge rates and parameters affect how effective energy stores can be. We carry out detailed time based energy store modelling to optimise storage performance and efficiency.
By analysing network dynamics, charge and discharge cycles, and system interactions, we help clients understand operational performance, inform sizing and design, and support investment decisions. This modelling ensures energy stores deliver maximum value and integrate effectively with wider heating or electrical networks.
Electrical storage
Assessing how to get the best impacts from local renewable generation, microgrids, electricity demand, time of use tariffs and sector coupling involves detailed models that can simulate technical and commercial scenarios.
We provide support for battery and other electrical storage systems, including feasibility, techno-economic assessment, sizing, specification, and integration with generation or demand assets.
Benefits include grid balancing, demand management, improved renewable energy utilisation, and maximised return on investment.
Our services ensure electrical storage is technically robust, operationally practical, and commercially viable.
