RAEL lunch seminar: Development and Test Plans for a small Vertical Axis Turbine Designed and Built by the Russian State Rocket Center, under Berkeley Lab auspices

Date: 
Wednesday, April 7, 2010 - 12:00pm - 1:00pm

Location: 323 Barrows Hall (ERG Reading Room)

Summary: Berkeley Lab Engineering Division teamed with Empire Magnetics, Rohnert Park and the Makeyev State Rocket Center under a DOE NNSA non-proliferation project to develop and test a series of small wind turbines of vertical axis design. Over the years, about 100 Russian scientists and engineers worked on the project and the hydrodynamic, aerodynamic and mechanical test facilities of the SRC were used. The objective was to create a highly manufacturable Darieus unit with a modest Tip Speed Ratio (quiet and low impact damage potential) that would be suitable for urban or village use. Test units of 1, 3 and 30 kW were completed and 5 3 kW beta units arrived in California in December. They will be tested to the new Small Wind Certification Committee standards of AWEA in the next few months under funding provided under the Technology Commercialization Fund of the lab. Commercial sales have begun in Russia and Empire Magnetics is forming a company for sales outside the FSU. Presuming the test program to be successful, future contributions by Berkeley Lab and the Campus will be discussed.

RAEL Lunch Seminar: "An Economic Analysis of Wind Energy Harvest"

Date: 
Wednesday, March 10, 2010 - 12:00pm - 1:00pm

Location: 323 Barrows Hall (ERG Reading Room)

Summary: We will present a new approach to wind energy development that simultaneously optimizes a wind farm and its financing for an improved economic analysis of wind energy projects. In our analysis we compare the energy yield of optimal wind energy projects with different turbine technologies under varying electricity price and wind speed scenarios. We perform extensive simulation studies and build statistical confidence intervals for the annual energy yield as well as the project's net present value at risk. The proposed approach eliminates the need for a trial-and-error financial feasibility study and, consequently, improves the harvest of the wind energy.

Carey King, Research Associate, Jackson School of Geosciences

Dr. Carey King studies energy systems, how they work together, how they impact the environment, and how and why humans as a society consume energy resources. He specializes in dynamic systems modeling and nonlinear optimization methods. Much of his recent work has focused on the nexus between energy and water for projecting water demand for electricity generation and alternative automobile fuels. As part of his energy-water studies, Dr. King has authored journal publications, a chapter for the Texas State Energy Conservation Office on the role of water in Texas' energy future as well as a report for the Texas Water Development Board that projects water demand scenarios for future electricity production. Additional work in which Dr. King is engaged includes the economics of carbon capture and sequestration, the design of beneficial combinations of renewable energy and storage systems, and the creation of tools to help the public and policymakers understand the trade-offs among different electricity generation sources.
