Energy Department, Power Institute probe walls’ thermal mass

A $65 million Department of Energy (DOE) program will support technologies enabling energy-efficient buildings to interact with one another and the electric grid, potentially lowering greenhouse gas emission levels and improving power infrastructure. Energy Secretary Dan Brouillette announced the funding commitment last month during an Electric Power Research Institute (EPRI) gathering in Charlotte, N.C., where attendees toured a Meritage Homes…

Atlanta-based Quikrete Companies and the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory, Tennessee, have entered a cooperative research and development agreement to design next-generation concrete for production of large-scale structures or elements through a 3D printing process (see “Sweet Success,” page 50). Using an Oak Ridge-developed additive manufacturing system, the two-phase, two-year collaboration will target specially-formulated mixes spawning new construction capabilities.

A $250,000 infusion from the Colorado Office of Economic Development and International Trade’s Advanced Industries Accelerator Grant Program will position Boulder-based concrete construction specialist RCAM Technologies and technology integrator Accucode Inc. to develop wind energy components using 3D printing methods. The grant supports RCAM work on a concrete wind turbine foundation with the potential to reduce offshore deployment costs by up to $4 million per structure and $400 million per plant. The firm will use the funding to expand its 3D concrete printing capabilities at two Colorado partner locations: the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) in Golden, and Accucode’s new Colorado Springs facility.
