Decarbonise Cold Storage

Reduce costs. Increase resilience. Secure your energy future.

Sherwood Power’s Free Air Battery delivers high-efficiency, zero-emissions energy storage for cold storage facilities. Cut peak energy costs, strengthen your resilience, and meet your net zero goals — all at once.

The Problem

Cold storage is one of the most energy-intensive industrial sectors, operating 24/7 to maintain strict temperature control. Energy use can accounts for up to 70% of a facility’s operational costs with demand often peaking during the most expensive grid periods. At the same time, operators face growing pressure to decarbonise and improve energy resilience.
 
Grid access is another critical challenge. Many facilities are located near ports or industrial hubs where local networks are already congested. Upgrading or expanding connections is often slow, expensive, and uncertain.

The Sherwood Solution

Sherwood Power’s Free Air Bank (FAB) provides embedded, zero-emission energy storage that captures and releases energy in two forms — compressed air and heat — delivering high efficiency and flexibility for cold storage operations
 
✅ Increase electricity supply capacity, on time, at an economic price.
✅ Reduce peak energy costs using excess electricity during peak periods.
✅ Decarbonise operations by onsite green energy.
✅ Avoid curtailment charges and absorb excess generation during low demand.
 
Technical Performance
  • Offers round-trip efficiency of 80%
  • Has a lifespan of 30+ years with minimal maintenance.
  • Is scalable from 1 – 100 MW and 1 – 1,200 MWh.
  • Modular and containerised rapid deployment, scales to your business.
  • Emissions: Produces zero emissions and is designed for recycled.

Why Cold Storage Needs On-Site Storage​

High Base Load

cooling demands large, predictable electricity supply

Increased electrification

demand for onsite and offsite transport

Cost control

limit exposure to time of use price spikes (2–3× higher)

Avoid delays

sites can grow without grid instability constraints

Benefits for Cold Storage Operators
