Lower Costs. Increase Resilience. Decarbonise Cold Storage.
Refrigeration is essential. Energy waste isn’t.
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.
Cold Storage Is One of the Most Energy-Hungry Sectors — And One of the Most Impactful to Decarbonise
Cold storage facilities consume 4–5x more energy per square foot than typical commercial buildings. With refrigeration accounting for up to 80% of their energy use, operators face:
- Volatile energy costs
- Rising curtailment and negative pricing periods
- Pressure to decarbonise from supply chain partners and regulators
Sherwood Power offers a new approach — scalable, site-based energy storage that slashes bills, improves uptime, and aligns with sustainability goals.
