Sustainable Clean Energy Laboratory (SCEL) research encompasses the creation, synthesis, and characterization of energy materials, as well as the design, fabrication, and testing of energy devices (e.g., solid oxide cells and membrane reactors). The processing techniques include material jetting, ultrasonic spray coating, direct laser-reactive additive manufacturing of ceramics, metal alloys, and ceramic/metal composites, laser sintering/synthesis/machining, and solid-state reactive sintering. The applications include resilient and efficient energy conversion/storage, hydrogen production, power generation, fuel processing, membrane separation, natural gas utilization, isotope separation, and production/separation/recycling of critical materials. Modern AI/ML tools are used to accelerate research.
