High efficiency carbon capture with FlueCO₂ Membranes

In the effort to achieve reduced carbon emissions globally, capturing carbon at the source (point capture) is a critical component to any viable strategy.  The FlueCO₂ technology, developed by Luna Labs, is designed for integration into natural gas combined cycle (NGCC) power plants to capture CO₂ post-combustion by removing carbon from the flue gas. The FlueCO₂ membrane works with an active transport mechanism that powers CO₂ separation with low pressure steam and H₂O’s concentration gradient. FlueCO₂ offers superior separation performance capture with an unrivaled combination of CO₂ permeability and selectivity of CO₂ over nitrogen (N₂).

Using methodologies laid out in the National Energy Technology Laboratory (NETL) Cost and Performance Baseline for Fossil Energy Plants, Luna Labs modeled the performance of NGCC power plants with the FlueCO₂ technology across different electricity pricing scenarios, carbon tax/credit structures, and regulatory structures.  FlueCO₂ NPV projections are greater than the B31A power plant in any future regulatory/tax scenario and outperforms the B31B power plant in all 14 scenarios.

Conventional Dual-Phase Membranes

• Molten carbonate liquid phase
• Solid oxide ion conduction required to maintain mass/charge balance and transport CO₂ through liquid phase
• Requires high temperatures (>600 °C)

FlueCO₂ Dual-Phase Membranes

• Molten hydroxide-carbonate liquid phase
• All mass transport through the liquid phase by coupling CO₂ permeation with the partial pressure of water vapor
• Fast, low temperature operation (200 °C)
