The final week of the 2020 Virtual Integrated Project Review Meeting, hosted by the U.S. Department of Energy (DOE) and NETL, will explore the accomplishments and upcoming work to be undertaken by two NETL-led programs — the National Risk Assessment Partnership (NRAP) and the Science-informed Machine Learning for Accelerating Real-Time Decisions in Subsurface Applications (SMART) Initiative.  A full slate of presentations and updates on the SMART Initiative will be held Monday, Nov. 2, and Tuesday, Nov. 3. Click here to review the SMART Initiative Annual Review Meeting agenda and to obtain online registration and WebEx instructions. The NRAP Technical Meeting, scheduled for Wednesday, Nov. 4, and Thursday, Nov. 5, will feature an array of speakers who will discuss the development of tools and approaches for effective risk management of carbon storage sites.

A team of national laboratories, led by Lawrence Berkeley National Laboratory and Lawrence Livermore National Laboratory (LLNL) with support from the National Energy Technology Laboratory (NETL) and Stanford Linear Accelerator Laboratory, is collaborating in a multi-scale modeling project that resulted in an approach that significantly improves the prediction of hydraulic fracture propagation. The results and modeling approach from the multi-lab project titled “A New Framework for Microscopic to Reservoir-Scale Simulation of Hydraulic Fracturing and Production: Testing with Comprehensive Data from Hydraulic Fracturing Test Site (HFTS) and Other Hydraulic Fracturing Field Test Sites” have since been adopted by numerous oil and natural gas operators following the publication by the Society of Petroleum Engineers (SPE).

NETL researchers such as Dominic Alfonso are using advanced computational tools to repurpose carbon dioxide (CO2) from a waste product into chemical building blocks to manufacture fuels and a range of high-value items. The work undertaken by Alfonso and other members of NETL’s Computational Materials and Engineering Team focuses on recycling CO2 generated by fossil energy plants and other industrial sources into chemicals, alcohols, acids and syngas, which are used to manufacture fuels, polymers and fertilizer. “For more than a century, we have used fossil fuels to produce our electricity and for a variety of other purposes. However, when we extract energy from fossil fuels, we create CO2, the primary greenhouse gas emitted through human activities,” Alfonso said. “We can address this issue by using CO2 from factories and power plants as a chemical feedstock. Waste CO2 emissions can become something you can recycle into valuable products, providing a strong financial incentive to reduce the amount of CO2 released into the atmosphere,” he added.

Since joining NETL last year, computer scientist MiKyung Kang, Ph.D., has supported the Lab’s high-performance computing (HPC) environment across all three of its research facilities, empowering the Lab to continue finding new ways to fuel the nation using the abundant supply of fossil fuels in a sustainable manner. Kang grew up on South Korea’s Jeju Island, one of the world’s New 7 Wonders of Nature and well known for its beautiful sand beaches and volcanic landscape of craters and cave-like lava tubes. She earned her B.S., M.S., and Ph.D. in computer science and statistics from Jeju National University, inspired by the rapid changes in technology she saw growing up. New Tech, New Possibilities

Representatives from alloy producers, original equipment manufacturers, end users and other industrial stakeholders will join NETL and other national laboratories to review research plans and progress during the virtual 2020 eXtremeMAT Industrial Stakeholder Meeting on Thursday, Oct. 15, 2020. Fossil energy transformational power technologies like ultra-supercritical steam plants and supercritical carbon-dioxide power systems have the potential to increase efficiencies and bolster clean coal efforts because they operate at higher temperatures and pressures. However, these technologies are subject to “extreme” operating environments – harsher and more corrosive conditions compared to those found in traditional power plants. Furthermore, today’s current fleet of fossil power plants are increasingly being subjected to cycling conditions due to the penetration of renewable energy sources into the electricity grid. Accelerating the development of improved steels, superalloys and other advanced alloys is of paramount importance in deploying materials solutions to address materials challenges associated with both the existing fleet and future power systems.

In an effort that could lead to accelerated design and deployment of advanced energy systems, NETL researchers have added a valuable new capability to the Lab’s world-renowned Multiphase Flow with Interphase eXchanges (MFiX) modeling software suite. Rather than modeling particles as spheres, as is the case with most discrete element modeling (DEM) techniques, NETL researchers have developed and validated an algorithm to simulate non-spherical shapes that better approximates real-world particles, significantly increasing modeling accuracy. Real-life granular materials such as coal and biomass are non-spherical in nature. However, researchers have long used simple spheres in DEM simulations to represent various interacting particles found in multiphase flow systems like fluidized beds, gasifiers and chemical looping reactors. While this technique is computationally efficient and allows for the simulation of hundreds of millions of particles necessary to model industrial-scale systems, it fails to adequately account for the gas-solid interaction in the reactor. 

NETL Director Brian Anderson will join other experts in rare earth elements (REEs) and critical materials (CMs) at a congressional launch of the House Critical Materials Caucus, being held virtually Sept. 24 at 12 p.m. (ET).   Anderson will join representatives Guy Reschenthaler and Eric Swalwell, who co-chair the Caucus, along with Adam Schwartz, director of Ames Laboratory, and Brian Gabriel, industrial analyst with the Office of the Deputy Assistant Secretary of Defense for Industrial Policy. Representatives Reschenthaler and Swalwell announced formation of the new House Critical Materials Caucus on July 24, 2020, to help the United States develop the technical expertise and production capabilities to assure a long-term, secure and sustainable supply of energy critical elements. Anderson will introduce NETL’s scientific and technical solutions aimed at developing an economically competitive supply of REEs and CMs, which will assist in securing and maintaining the nation’s economic growth and national security.

A program supported by NETL will prepare a new generation of welders in the use of advanced alloys that will enable electric generating stations to run with greater efficiency, produce fewer greenhouse gas emissions and supply affordable electricity using the nation’s abundant fossil energy resources.   Today, the Appalachian Regional Commission (ARC), the Lab’s partner in the Advanced Welding Workforce Initiative (AWWI), issued a request for proposals (RFP) inviting states, counties and cities, institutions of higher education, unions and other organizations to develop training programs to teach high-tech welding skills that can be used in the energy sector. These skills will also be broadly applicable for positions in the emerging aerospace, aviation, automotive and petrochemical industries, which will need welders and other employees with expertise in working with high-performance materials.

Key recommendations to guide the operation of a first-of-its-kind testing facility to develop next-generation power plants have been issued by NETL researchers. If successful, testing at this facility will provide a pathway to lower the cost of electricity, shrink the environmental and physical footprint of power generation systems and conserve water.
