The U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) announced on November 27, 2023, that a machine learning tool developed by the National Renewable Energy Laboratory (NREL), with support from BETO, makes it easier for material scientists to “mak[e] polymers more sustainable and higher performing — especially with the reliance on petrochemicals for making plastics.” According to BETO, using artificial intelligence (AI), PolyID: Polymer Inverse Design™ “can...

By Lynn L. Bergeson and Carla N. Hutton   The U.S. Department of Energy’s Bioenergy Technologies Office (BETO) announced on January 23, 2023, that researchers at the National Renewable Energy Laboratory (NREL) examined the benefits and trade-offs of current and emerging technologies for recycling certain types of plastics to determine the optimal options. According to BETO, the researchers provided a comparison of various closed-loop recycling technologies, which allow for the reuse...

By Lynn L. Bergeson and Ligia Duarte Botelho, M.A.   On July 6, 2021, the U.S. Department of Energy (DOE) Bioenergy Technologies Office (BETO) and National Renewable Energy Laboratory (NREL) announced Phase I selections for the Waste-to-Energy Technical Assistance for Local Governments Program. Designed by NREL to provide assistance in the development of waste-to-energy (WTE) technologies on behalf of BETO, the goal of this program is to identify gaps and gather data and...

By  Lynn L. Bergeson and Ligia Duarte Botelho, M.A. National Renewable Energy Laboratory (NREL) researchers are leading analyses of recycling, repairing, and reusing solar photovoltaic (PV) installations in support of NREL’s mission to incentivize a circular economy for energy materials.  According to NREL, the increase in the installation of PV systems is leading to environmental and supply chain concerns because the technology relies on imports and mining of raw...

By Lynn L. Bergeson and Ligia Duarte Botelho, M.A. On February 22, 2021, the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) announced its comprehensive strategy to decarbonize transportation by 30-85 percent by 2050. A strategy based on research and engineering, it aims to enable industry stakeholders, government bodies, communities, and early adopters to meet their climate goals. In a nutshell, the strategy takes a whole-system approach to...

By Lynn L. Bergeson On March 22, 2018, the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) announced that by studying and comparing the cellulose-degrading enzymes of two fungi, NREL researchers have pinpointed regions on these enzymes that can be targeted via genetic engineering to help break down cellulose faster.  The article published in Nature Communications, “Engineering enhanced cellobiohydrolase activity,” describes NREL’s...

By Kathleen M. Roberts Researchers at the DOE National Renewable Energy Laboratory (NREL) are seeking responses to a survey on biorefinery operations.  Yimin Zhang, an environmental engineer at NREL, and Marshall Goldberg, a subcontractor for NREL, developed the brief survey to improve the NREL’s understanding of the next generation biofuel industry and its contribution to the local, state, and national economy.  Industry stakeholders in the planning, construction, or...

By Kathleen M. Roberts On November 29, 2017, the U.S. Department of Energy (DOE) announced that a collaboration between the National Renewable Energy Laboratory (NREL) and Oak Ridge National Laboratory (ORNL) resulted in the successful modification of a microorganism to produce a versatile fermentation intermediate that can be upgraded into valuable biobased fuels and chemicals.  NREL’s cellulosic ethanol fermentation organism (Zymomonas mobilis), is capable of exclusively...

By Lauren M. Graham, Ph.D. On September 26, 2017, the U.S. Department of Energy (DOE) announced the selection of an additional project for the Bioenergy Technologies Office’s (BETO) Advanced Algal Systems Program funding opportunity announcement (FOA).  DOE is awarding up to $3.5 million to the National Renewable Energy Laboratory (NREL) to more than double the productivity of biofuel precursors from algae.  Researchers aim to improve productivity by increasing algal...
