Cutting-Edge Modeling Tools to Enable Low Carbon Grids

11/04/19 • 27 min

Decarbonizing our electricity and transportation sectors will require large deployments of wind, solar, and storage. Ranjit Deshmukh develops models for planning and operations of low carbon electricity grids and analyzes tradeoffs between economic, environmental, and social objectives for regions in the U.S., India, and Africa. These models optimize wind, solar, and other generation, demand, and storage resources for region-specific conditions including spatial and temporal variability of renewable resources.

Coastal Water Security with Distributed Offshore Reverse Osmosis

California's recent drought has highlighted the need for a reliable source of water. Peter Stricker of SeaWell presents a reverse osmosis (RO) system to address climate-driven drought which is an entirely new approach to water supply. The SeaWell buoy is a self-contained floating vessel, moored to the sea floor, with seawater intake and brine diffusion outfall. It contains reverse osmosis equipment, electric power and water piping, and can permeate water at a rate of 950–3,800 acre-feet/year. The implementation plan is to deploy pilot SeaWell Buoys at a water cost already below the cost of State water,initially partnering with water districts to deploy five water portals. Landing sites could be chosen based in previously disturbed areas, such as decommissioned oil receiving facilities and sanitary district outfalls. These deployments will augment new water reuse projects, and share siting and infrastructure. Series: "Institute for Energy Efficiency" [Science] [Show ID: 35163]

Navigating the Design Space of Trajectories Toward Low/Zero-Carbon Energy Systems in California

Transforming our energy infrastructure to support greenhouse gas (GHG) emissions reduction goals will require the deployment of technologies such as electric vehicles and energy storage. Improper integration of these technologies into the electric grid and a lack of careful planning of their scale, however, can significantly reduce their real-world effectiveness in supporting GHG emissions reduction goals. Research by Brian Tarroja and his colleagues at UC Irvine presented here focus on identifying grid integration needs and life cycle planning considerations for electric vehicles and energy storage deployment to better ensure that their potential GHG benefits are fully realized in future electricity systems.
