US carbon capture specialist Mantel has partnered with Danish thermal energy engineering firm Aalborg CSP to standardise the plant design of its molten salt tank systems for commercial high-temperature carbon capture deployments.
Mantel told gasworld the standardised molten salt tanks are expected to support a roughly 300,000 tonne per year carbon dioxide (CO2) capture system.
The modular design, however, could support projects double or ten times that size without increasing foundational risk.
Under the new agreement with Aalborg CSP, Mantel will leverage Aalborg CSP’s molten salt system engineering experience to standardise its technology and reduce costs across commercial projects.
As part of the collaboration, the subsystem will be manufactured off-site and will contain critical instrumentation, storage, and heating operations.
In terms of the project’s timeline, Cameron Halliday, CEO of Mantel, told gasworld, “The core work will be completed over the next 12 months, [and] a repackaging of the demonstration core concepts will avoid novel piloting deployment.”
The standard design will be informed by Mantel’s 2,000 tonnes of CO2 capture per year at Canadian renewable energy company Kruger’s Wayagamack pulp and paper mill in Quebec, he added.
Mantel is currently advancing several commercial projects that will use the standardised salt tank design. Moving forward, the design will be used across all of Mantel’s future commercial deployments.
CO2 capture technology
Mantel’s molten salt tank subsystem integrates directly into high-temperature industrial operations where steam and heat are critical, including power generation, manufacturing, and oil and gas.
Industrial emissions are absorbed by the molten borate salt, capturing the CO2 and releasing energy, while recovering process heat as clean steam.
The process is said to reduce energy losses and produce a high-purity CO2 stream suitable for sequestration or use without further treatment.
