Concentrating Solar Power Program Review 2013 (Book) (Revised) APRIL 23–25, 2013 CONCENTRATING SOLAR POWER PHOENIX, ARIZONA PROGRAM REVIEW 2013 SunShot Concentrating Solar Power Program Review 2013 Welcome Dear Colleague: On behalf of the U.S. Department of Energy (DOE) SunShot Initiative, it is my pleasure to welcome you to the SunShot Concentrating Solar Power (CSP) Program Review 2013. The SunShot Initiative was launched in 2011 as a national collaborative effort aimed at addressing an aggressive cost reduction goal for solar-generated electricity to achieve grid parity without subsidy by the end of the decade. Since October 2011, the SunShot CSP Program has committed over $130M to new funding initiatives for CSP technologies. Combined with the awards continuing from prior funding opportunities, the Program maintains an appropriately balanced portfolio of projects at industry, national laboratories and universities developing technologies for the near-, mid- and long-terms. The Program Review features presentations by DOE awardees working at the forefront of research, development, and demonstration towards reducing costs and increasing performance of CSP technologies. The Review also brings together a broad base of external stakeholders to engage in and contribute to the deployment of the CSP technologies being developed under the SunShot Initiative. Plenary sessions on each day of the meeting include keynote talks that offer broad perspectives on topics ranging from quantifying the value of CSP and thermal energy storage, presented through grid integration analysis as well as from the vantage of a utility company, to global projects and opportunities for CSP from an international financing viewpoint. Complementing the keynote presentations are highlight talks featuring three recently graduated projects from the portfolio that have leveraged successful technology developments with DOE funding and continued the momentum towards commercialization. It is an exciting time for CSP, with tremendous activity building up worldwide as many countries invest in CSP systems as part of their sustainable energy infrastructure. In the U.S., several large-scale commercial CSP plants are poised to be commissioned beginning in 2013 that will collectively more than triple the current capacity. As a culminating event of the Program Review, attendees will have a unique opportunity to witness a part of this growth through a tour of the Abengoa Solana Generating Station, a 280 MW parabolic trough plant with six hours of thermal energy storage—one of the brand new CSP plants revving up to contribute to the nation’s renewable energy portfolio. Your participation greatly enhances the success of the Program Review, and I invite you to have engaging discussions with the attendees—be it for networking, seeding collaborative ventures or providing technical feedback.

  • Estimating the Quantity of Wind and Solar Required to Displace Storage-Induced Emissions † ‡ Eric Hittinger*, and Ineŝ M
    Article Cite This: Environ. Sci. Technol. 2017, 51, 12988-12997 pubs.acs.org/est Estimating the Quantity of Wind and Solar Required To Displace Storage-Induced Emissions † ‡ Eric Hittinger*, and Ineŝ M. L. Azevedo † Department of Public Policy, Rochester Institute of Technology, Rochester, New York 14623, United States ‡ Department of Engineering & Public Policy, Carnegie Mellon University, Pittsburgh, Pennsylvania 15213, United States *S Supporting Information ABSTRACT: The variable and nondispatchable nature of wind and solar generation has been driving interest in energy storage as an enabling low-carbon technology that can help spur large-scale adoption of renewables. However, prior work has shown that adding energy storage alone for energy arbitrage in electricity systems across the U.S. routinely increases system emissions. While adding wind or solar reduces electricity system emissions, the emissions effect of both renewable generation and energy storage varies by location. In this work, we apply a marginal emissions approach to determine the net system CO2 emissions of colocated or electrically proximate wind/storage and solar/storage facilities across the U.S. and determine the amount of renewable energy ff fi required to o set the CO2 emissions resulting from operation of new energy storage. We nd that it takes between 0.03 MW (Montana) and 4 MW (Michigan) of wind and between 0.25 MW (Alabama) and 17 MW (Michigan) of solar to offset the emissions from a 25 MW/100 MWh storage device, depending on location and operational mode. Systems with a realistic combination of renewables and storage will result in net emissions reductions compared with a grid without those systems, but the anticipated reductions are lower than a renewable-only addition.

From the start, the company has always strived to do more, and to do important and meaningful things with the resources we have. Alphabet is a collection of businesses -- the largest of which is Google. It also includes businesses that are generally pretty far afield of our main internet products in areas such as self-driving cars, life sciences, internet access and TV services. We report all non- Google businesses collectively as Other Bets. Our Alphabet structure is about helping each of our businesses prosper through strong leaders and independence. We have always been a company committed to building products that have the potential to improve the lives of millions of people. Our product innovations have made our services widely used, and our brand one of the most recognized in the world. Google's core products and platforms such as Android, Chrome, Gmail, Google Drive, Google Maps, Google Play, Search, and YouTube each have over one billion monthly active users.

  • Abengoa Solar Develops and Applies Solar Energy Technologies in Order
    Solar Abengoa Solar develops and applies solar energy technologies in order to combat climate change and ensure sustainability through the use of its own Concentrating Solar Power (CSP) and photovoltaic technologies. www.abengoasolar.com Solar International Presence Spain China U.S.A. Morocco Algeria 34 Activity Report 08 Solar Our business Abengoa is convinced that solar energy combines the characteristics needed to resolve, to a significant extent, our society’s need for clean and efficient energy sources. Each year, the sun casts down on the earth an amount of energy that surpasses the energy needs of our planet many times over, and there are proven commercial technologies available today with the capability of harnessing this energy in an efficient way. Abengoa Solar’s mission is to contribute to meeting an increasingly higher percentage of our society’s energy needs through solar- based energy. To this end, Abengoa Solar works with the two chief solar technologies in existence today. First, it employs Concentrating Solar Power (CSP) technology in capturing the direct radiation from the sun to generate steam and drive a conventional turbine or to use this energy directly in industrial processes, usually in major electrical power grid-connected plants. Secondly, Abengoa Solar works with photovoltaic technologies that employ the sun’s energy for direct electrical power generation, thanks to the use of materials based on the so-called photovoltaic effect. Abengoa Solar works with these technologies in four basic lines of activity. The first encompasses promotion, construction and operation of CSP plants, Abengoa Solar currently designs, builds and operates efficient and reliable central receiver systems (tower and heliostats) and storage or non-storage-equipped parabolic trough collectors, as well as customized industrial installations for producing heat and electricity.
