Our Solution

The primary challenge in scaling up carbon capture technology is not its technical feasibility, but its cost. The cost is particularly high in industries such as cement ($104 to $194 per tonne) and steel ($71 to $119 per tonne). Consequently, these sectors are often reluctant to adopt carbon capture solutions despite their significant COâ‚‚ emissions. To drive meaningful adoption, any breakthrough in carbon capture must substantially reduce these costs.

​

 To address this, we have developed two key innovations:

  1. Limeloop — our proprietary carbon capture material that captures 36 times more COâ‚‚ over its lifetime than natural limestone.

  2. Smart Carbon Capture Battery (SCCB) — our novel carbon capture process that integrates carbon capture with a heat battery. By leveraging fluctuations in electricity prices, SCCB effectively reduces the energy costs associated with COâ‚‚ capture by more than 80%.

Limeloop

Our proprietary sorbent, Limeloop, was developed by Moji over four years of PhD research. Through extensive R&D, we identified the most effective and cost-efficient synthetic limestone. Our innovation lies not only in the selection of stabilizers but also in their unique dispersion method. This technique allows the stabilizers to form a structural skeleton within the sorbent, preserving its performance across multiple cycles. As a result, Limeloop can capture 36 times more COâ‚‚ over its lifetime compared to natural limestone, reducing material costs by over 80% and significantly improving the economic feasibility of calcium looping for large-scale carbon capture.

Smart Carbon Capture Battery

At Remedium, we have developed a heat battery that operates by capturing carbon dioxide from high emitting industries to store electricity. Remedium's carbon capture heat battery is the first of its kind and by adding revenue to carbon capture, it drives down the cost associated with it. Deploying our technology:

  • minimizes your carbon dioxide emission,

  • at minimum carbon capture cost of only $10 per tonne,

  • and provides a high temperature heat storage solution.

Modular Carbon Heat  Battery

The third product we are developing at Remedium is a modular heat battery that leverages Limeloop’s high performance to provide efficient high-temperature heat storage. Utilizing the same chemical reaction as our Carbon Capture Heat Battery, the Modular Carbon Heat Battery (MCHB) is a scalable solution designed for industrial applications. Available in two sizes—20 ft units with a 7-8 MWh capacity and 40 ft units with a 15-20 MWh capacity—MCHB offers a compact, cost-effective, and flexible approach to high-temperature heat storage, making it ideal for a wide range of industrial processes.
