Explore the solution ↗︎What is the Free Air Bank?
The Free Air Bank, or FAB, is Sherwood Power's energy storage system. We use air and water to store energy, helping businesses save surplus renewable generation for later use.
What energy sources can the FAB work with?
The FAB can bank energy from any electricity source, including wind, solar, anaerobic digestion, biomass and combined heat and power (CHP). It can also work with a diesel generator where storage could help it operate more efficiently.
Electricity can come from generation on site, supply through the grid or a blend of both. Your supply sources, generation plans and demand profile help us explore the right configuration for your site.
How long can energy be stored?
Duration depends on the configuration and how retained heat is managed.
Tell us when energy is available and when you need it. Those timings help define what your system should do.
How does the FAB compare with other storage options?
Start with your requirements: demand, duration, space, costs and future plans. Ask for a like-for-like assessment based on the same operating conditions.
We can discuss where the FAB could fit within your site's energy strategy.
Built around
your requirements
Think about today's needs and tomorrow's changes.
How much energy can a system store?
The FAB is modular. Storage capacity and electricity output are sized separately.
Share your demand profile and the hours you want to cover so the discussion starts with your needs, rather than a standard package.
How much space will we need?
Request a site-specific layout covering the equipment footprint, access, connections and maintenance space.
A site plan is a useful starting point. A generic container dimension isn't a complete installation layout.
Can the system grow with our business?
Yes. Additional storage and generation modules can support changing needs.
Discuss planned loads, new tenants or further development early, so expansion can be considered in the site layout.
Can we relocate it if our lease ends?
The containerised modules can be relocated, subject to assessment of the new site and its connections.
If relocation is part of your plans, raise it at the start of the project.
What does a FAB system cost?
Request a quotation for your configuration and installation. Share your site location, energy needs and project plans to help define the scope.
Ask for clarity on what the proposal includes, from equipment and integration to ongoing support.
The detail behind
the decision
Request the specifications relevant to your proposed system.
Request technical information ↗︎How efficient is the FAB?
Ask for current round-trip efficiency data, including the system configuration, operating conditions and what is included in the measurement.
Use that information to compare options on a consistent basis.
What pressure does the system operate at?
Request the current pressure specification and safety information for the proposed configuration as part of your technical review.
What operating life should we plan for?
Ask for the design-life assumptions, maintenance schedule, component replacement plans and warranty terms for your proposed system.
Can charging and discharging happen at different rates?
Yes. Different rates and simultaneous operation can be designed into the system.
Discuss the operating pattern you need during the configuration review.
Does it always discharge at full output?
No. Discharge output can be varied.
Ask for the operating range and control approach relevant to your site's demand.
