The U.S. Department of Energy’s (DOE) Office of Fossil Energy is investing $4m in federal funding for four national lab-led research and development projects to identify new concepts and technologies for producing oxygen (O2) via air separation for use in flexible, modular gasification systems.
These projects are supported through a Laboratory Research Call: ‘Technical Support for Advanced Air Separation Concepts and Technologies for the Production of Oxygen’, issued in June 2018. The objective is to develop air separation technologies to be used in advanced fossil energy-based modular energy systems that will make progress toward enabling cost-competitive, coal-based power generation with near-zero emissions. The air separation technologies developed could eventually find applications in coal-fed, small-scale (1-5 MWe) modular gasification-based power plants.
The National Energy Technology Laboratory (NETL) will manage the projects, which are described below:
‘Advanced Oxygen Separation from Air Using Novel Mixed-Matrix Membranes’ – Idaho National Laboratory (Idaho Falls, ID) intends to create a durable, high-performing membrane material that dramatically advances current technology by taking advantage of an O2/nitrogen (N2)-selective polymer material and minimising or eliminating its loss of performance through the inclusion of chemically tailorable and durable nanoparticles.
