Power Conditioning Systems for Renewables, Storage, and Microgrids

Ongoing
Objective: To establish standards and measurement methods, and test for smart grid and microgrid Power Conditioning Systems needed to transition from today’s low penetration of nondispatchable intermittent renewable energy sources to flexible grid operations that can actively adjust to varying grid
Schematic of a radial p- n- Junction

Theory and Modeling of Materials for Renewable Energy

Ongoing
Nanostructured materials offer potential benefits for a range of renewable energy applications that rely critically on interfaces for separating charges, including photovoltaics, thermoelectrics, and electrochemical energy storage. The use of nanostructures allows scientists and engineers to

Sub-nanoscale electron microscopy of complex nanostructures

Ongoing
The properties of advance materials are becoming ever more reliant on the ability to manipulate their chemistry and structure at very fine length scales. For example, the relevant feature sizes in state-of-the-art transistors continue to decrease, even as the complexity of the architectures employed
hydrogen gas dispensers test

Portable Field Test Standard for Evaluation of Hydrogen Gas Dispensers

Completed
This project provides a metrological tool and standards supporting the fair trade of hydrogen gas as a vehicle fuel of the future. Objective(s): The Fluid Metrology Group (FMG) and the Office of Weights and Measures (OWM) collaborated in designing, constructing, and testing a hydrogen gas dispenser
