Rising Tide Lifts All Buoys
PNNL served as workshop partner for the 2024 Marine Technology Society Buoy Workshop, held this year in Sequim, Washington, where PNNL operates the only marine research facilities in the Department of Energy system.
PNNL to Install 24-Hour Flow Battery in Richland Campus
This is the first time a flow battery with 24-hour discharge capacity will be deployed and tested in a field environment.
SYSTEMS AND METHODS FOR MONITORING ORGANISMS WITHIN AN AQUATIC ENVIRONMENT
Systems and methods for monitoring organisms within an aquatic environment are described. According to one aspect, an injectable acoustic transmission device includes a body configured to be injected inside of an organism, a transducer within the body and configured to convert a plurality of electrical signals into a plurality of data transmissions which are transmitted externally of the body and the organism, a plurality of circuit components within the body and configured to use electrical energy from a power source to generate the electrical signals which are provided to the transducer, and wherein the transducer defines an internal volume and at least one of the circuit components is provided within the internal volume of the transducer.

GRID STABILIZATION USING ADJUSTED VOLTAGE REGULATOR RESPONSE TO GRID CHARACTERISTICS
This IDR proposes the use of volt-var optimization (VVO) to improve the dynamic performance of microgrids. The proposed idea uses existing hardware assets, and does not require expensive new equipment. Operationally the concept is similar to the power system stabalizers seen on large transmission generators, except that it is relying on the response of the end use load for the primary control affect. While VVO has been used to reduce energy consumption for 30+ years, the proposed work is operating on the time-sclae of milliseconds. This is a new way to use the VVO effect, and to my knowledge has not been done before.
New Sodium, Aluminum Battery Aims to Integrate Renewables for Grid Resiliency
A new sodium battery technology shows promise for helping integrate renewable energy into the electric grid. The battery uses Earth-abundant raw materials such as aluminum and sodium.
