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

✅ Reduce peak energy costs by consuming stored off-peak electricity during peak grid pricing periods.
✅ Enhance energy resilience, ensuring continuous operations even during outages or price spikes.
✅ Decarbonise operations by storing excess renewable energy (e.g. solar) generated on-site.
✅ Avoid curtailment charges and absorb excess generation during low demand.

✅ Delay or avoid grid upgrades through behind-the-meter installation, deliver new storage capacity on time.

Technical Performance

Is scalable from 1 – 100 MW and 1 – 1,200 MWh.
Modular and containerised for easy, flexible on-site installation and integration.
Emissions: Produces zero emissions and is designed for the circular economy.

Why Cold Storage Needs On-Site Storage

⚡ High base load: Continuous cooling demands large, predictable electricity supply

🚛 Electrification of onsite and offsite transport leads to increased demand

💷 Peak-time limit exposure: during demand spikes prices can be 2–3× higher.

🌱 Net-zero targets: The cold chain sector faces strict decarbonisation targets.

📉 Grid congestion: some UK sites face operations growth limits due to grid instability.
