The EGS Data Collaboration Platform: Enabling Scientific Discovery

Collaboration in the digital age has been stifled in recent years. Reasonable responses to legitimate security concerns have created a virtual landscape of silos and fortified castles incapable of sharing information efficiently. This trend is unfortunately opposed to the geothermal scientific community's migration toward larger, more collaborative projects. To facilitate efficient sharing of information between team members from multiple national labs, universities, and private organizations, the 'EGS Collab' team has developed a universally accessible, secure data collaboration platform and has fully integrated it with the U.S. Department of Energy's (DOE) Geothermal Data Repository (GDR) and the National Geothermal Data System (NGDS). This paper will explore some of the challenges of collaboration in the modern digital age, highlight strategies for active data management, and discuss the integration of the EGS Collab data management platform with the GDR to enable scientific discovery through the timely dissemination of information.

Getting Data Out of the Ground: Modern Data Challenges Facing EGS Collab, the DOE Geothermal Data Repository, and the Geothermal Industry

The amount of data being generated by the geothermal industry is increasing exponentially. Advanced tools, higher resolution sensors, and digitally integrated equipment are providing valuable insight into geothermal exploration and operational efficiencies, but the volumes of data they generate and the unique properties of Enhanced Geothermal System (EGS) projects are creating challenges of their own. This paper explores those challenges and the steps the U.S. Department of Energy (DOE) is taking to address them through comprehensive data management strategies, improvements to DOE's Geothermal Data Repository (GDR), and the development of a secure data collaboration tool for DOE's Frontier Observatory for Research in Geothermal Energy (FORGE) and EGS Collab projects.

3D printing of thermoset polymers and composites

The present disclosure provides a novel method of 3D printing using frontal polymerization chemistry. This method enables the printing of tough, high quality thermosets in a short time with the option of adding fiber reinforcement. As such, it facilitates fabrication of mechanically robust 3D-printed devices and structures.

Tersoff Benchmarking of Be-C-H Interatomic Potential

To demonstrate prolonged fusion power in ITERs (International Thermonuclear Experimental Reactors), the selection of appropriate plasma facing materials (PFMs) is a vital issue that requires the use of interatomic potentials to simulate the plasma interactions with the PFMs. So it is no surprise that the use of computer codes such as LAMMPS to perform studies in order to determine proper PFMs is necessary based on the complexity of such studies. In recent Tokamak advancements, beryllium was chosen as a first wall material due to its low Z (lower energy loss due to plasma contamination), its low tritium inventory and its oxygen gettering quality. With its high melting point and ability to withstand high heat fluxes, beryllium makes a fine choice for a PFM. In this work, Be-C-H (beryllium-carbon-hydrogen) bonds were investigated in a LAMMPS Tersoff simulation, where the interatomic potentials for Be-C-H were converted to LAMMPS Tersoff format, and were validated by calculating the cohesive energy (E{sub coh}), lattice constant (a), and atomic volume (V{sub 0}) for comparison to Density Functional Theory (DFT), Analytical Bond-Order Potentials (ABOP) and experiment potentials. This benchmark serves as the validation of performing Be-C-H bombardment simulations using LAMMPS.
