Northern Region Coal Prospects
This presentation was delivered to the audience attending the U.S. DOE/USEA Northern Regional Coal Workshop in Bismarck, ND on March 11, 2026. The presentation highlights the opportunity for coal plants in the region to provide power to military installations and data centers. There is also an analysis on how coal-fired power stations maintain regional supply during extreme cold weather events. Finally, a summary slide is presented that highlights a recent business case analysis on diverting captured carbon dioxide for use in enhanced oil recovery in the Bakken.

Development of Position-sensitive Transition-edge Sensor X-ray Detectors
We report on the development of position-sensitive transition-edge sensors (PoST's) for future x-ray astronomy missions such as the International X-ray Observatory (IXO), currently under study by NASA and ESA. PoST's consist of multiple absorbers each with a different thermal coupling to one or more transition-edge sensor (TES). This differential thermal coupling between absorbers and TES's results in different characteristic pulse shapes and allows position discrimination between the different pixels. The development of PoST's is motivated by a desire to achieve maximum focal-plane area with the least number of readout channels and as such. PoST's are ideally suited to provide a focal-plane extension to the Constellation-X microcalorimeter array. We report the first experimental results of our latest one and two channel PoST's, which utilize fast thermalizing electroplated Au/Bi absorbers coupled to low noise Mo/Au TES's - a technology already successfully implemented in our arrays of single pixel TES's. We demonstrate 6 eV energy resolution coupled with spatial sensitivity in the keV energy range. We also report on the development of signal processing algorithms to optimize energy and position sensitivity of our detectors.

NETL Coal Energy Atlas: A Collection of Coal/Energy Related Maps
The NETL Coal Energy Atlas contains a comprehensive collection of coal and energy-related maps and graphics curated by the National Energy Technology Laboratory (NETL) Systems Analysis group. It serves as a living document providing an overview of the U.S. coal and energy sectors. The volume is structurally organized into six key thematic areas. Ultimately, the atlas functions as a modular baseline for data integration, allowing researchers to drill down into specific regional locations or customize geographic base layers for advanced systems analysis.
