Lime|loop is a chemical heat battery. It charges on the cheapest electricity hours on the grid, delivers process heat up to 900°C, and captures the carbon from any gas you still burn, in a single cycle.

Gas is cheapest today, and live grid electricity at peak rates is uneconomic for 24/7 process heat. A heat battery bridges that gap, and Lime|loop adds a second CO₂ revenue stream that helps the asset pay for itself.
Averaged European reference figures for illustration.
A closed thermochemical loop using proprietary synthetic lime (CaO ↔ CaCO₃) to store energy in chemical bonds.
Off-peak electricity calcines the Lime|loop sorbent: CaCO₃ becomes CaO, storing energy chemically at high density.
Releases 700–900°C process heat on demand, around the clock, straight into your existing infrastructure.
The same cycle captures CO₂ from the gas you still burn. Offset your ETS bill, or sell to an off-taker.

Lime|loop uses a reversible CaO ↔ CaCO₃ cycle on a proprietary synthetic lime engineered for durability over thousands of charge–discharge cycles. Cheap inputs, dense energy storage, high-purity CO₂ output.
