DOE Investments in Environmentally Acceptable Lubricants for Hydropower Applications Fact Sheet

Environmentally acceptable lubricants (EALs) are defined as lubricants that meet U.S. Environmental Protection Agency (EPA) standards for “biodegradability, toxicity, and bioaccumulation potential that minimize their likely adverse consequences in the aquatic environment, compared to conventional lubricants.” Restrictions from state, local, and federal agencies, as well as a growing awareness of the environmental risks associated with petroleumbased lubricants, have shifted government and industry to seek out high-performing EALs. The U.S. Department of Energy (DOE) is working to reduce the environmental impacts of hydropower development and operation by investing in tools and methods to develop, demonstrate, and validate EAL materials.

The Environmental Molecular Sciences Laboratory (EMSL) 2020 Fact Sheet

EMSL, the Environmental Molecular Sciences Laboratory, is a U.S. Department of Energy (DOE) Office of Science User Facility supported by the DOE Office of Biological and Environmental Research (BER). Research at EMSL supports BER’s mission to understand the biological, biogeochemical, and physical principles needed to predict a continuum of processes occurring at the molecular and genomics-controlled smallest scales to environmental and Earth system change at the largest scales. EMSL is in Richland, WA, at Pacific Northwest National Laboratory.

Nanocomposite additives based on graphene sheets and silica nanofibers

A method for producing a composite polymeric article, an additive for a polymeric article, and a composite polymeric article are provided. The method generally includes providing a plurality of graphene nanoplatelets, providing a plurality of silica nanofibers, providing a polymeric material, and distributing the plurality of silica nanofibers and the plurality of graphene nanoplatelets within the polymeric material to achieve a composite article. The additive for a polymeric article includes a plurality of graphene nanoplatelets and a plurality of silica nanofibers. The composite polymeric article includes a plurality of graphene nanoplatelets, a plurality of silica nanofibers, and a polymeric matrix. The plurality of graphene nanoplatelets and the plurality of silica nanofibers are distributed within the polymeric matrix. The silica nanofibers have a mean cross sectional diameter of not more than 100 nm.

Resilient Energy Platform. Fact Sheet: Power Sector Cybersecurity Building Blocks

The Power Sector Cybersecurity Building Blocks, developed through the USAID-NREL Partnership and the Resilient Energy Platform, are designed to help a variety of stakeholders improve security for the electrical grid. This effort grows out of USAID and NREL's discussions with utilities around the world, as well as past cybersecurity assessments performed by NREL on dozens of utilities and government agencies, with a focus on the cybersecurity challenges faced by small and under-resourced utilities. This document outlines eleven building blocks for power sector cyber security. It functions as a guide to help organizations develop a robust, balanced cybersecurity defense program. Individually, each building block represents a cluster of related activities within cybersecurity on which an organization should focus. Using the building blocks, organizations can effectively prioritize their cybersecurity efforts to best thwart a wide range of potential cyberattacks.
