eREGENERATE - Resistive heating in structured hydrophobic sorbents for a highly efficient and fully electrified Direct Air Capture technology - addresses key challenges in DAC related to the high cost and energy consumption by combining durable, low-cost materials with a fully electrified process powered by renewable energy.
It introduces four main innovations:
- Hydrophobic zeolites are developed as long-lasting, water-repellent materials that efficiently capture CO2 even at low concentrations and in humid air.
- An electrically conductive support structure improves airflow, reduces energy use, and enables rapid heating for CO2 release.
- A novel electrical swing process uses renewable electricity for both capture and release.
- A first-of-its-kind algorithm that optimizes the entire CO2 capture and conditioning process, while also accounting for the energy source mix and the influence of weather conditions to help reduce the high energy demand of capture and improve both energy efficiency and CO2 purity along the way.
eREGENERATE has an interdisciplinary consortium consisting of the following 13 partners from 10 different countries. In addition to coordinating the project, SINTEF will also contribute to the development of the hydrophobic zeolites, process modelling and optimization, and lab-scale testing of the developed materials and modules.
