Does Concentrated Solar Power Have the Answer to Intermittency Concerns?

Does Concentrated Solar Power Have the Answer to Intermittency Concerns?

In this post John outlines two developments in the thermosolar concentrated solar power (CSP) arena that are enabling CSP to fulfill the role of baseload suppliers. Molten salt energy storage is naturally suited for CSP facilities and is quite efficient as an energy store — both in terms of low loss and in terms of capital expenditures (compared with batteries for example). By storing power in this way CSP plants can continue delivering power even after the sun has gone down. In addition by pairing CSP with stand-by combined-cycle natural gas generators greater overall reliability can be achieved.

U.S. High-Speed Rail: Time to Hop Aboard or Be Left Behind

U.S. High-Speed Rail: Time to Hop Aboard or Be Left Behind

In recent months, several conservative governors have rejected federal funds to begin constructing high-speed rail lines in their states. But a high-speed rail advocate argues that such ideologically driven actions are folly, as other U.S. states and countries around the world are moving swiftly to embrace a technology that is essential for competitive 21st-century economies.

Four Big Established US Solar PV Companies You Should Know About

Four Big Established US Solar PV Companies You Should Know About

In this survey we are looking at the large US headquartered solar PV manufacturers with a view to examine how they are doing in this difficult economic climate. As basically anyone knows, who has not been cloistered away meditating in some cave, 2009 has been a very tough year for pretty much everyone.

U.S. Department of Energy Announces Winners of the 2009 Solar Decathlon

The Solar Decathlon is a competition in which teams of college and university students compete to design, build, and operate the most attractive, effective, and energy-efficient solar powered house. The winners of the 2009 competition – the fourth to be held – were announced on the National Mall in Washington, D.C. by U.S. Department of Energy Deputy Secretary Daniel Poneman. The contest is organized by DOE’s National Renewable Energy Laboratory and supported by event and team sponsors from the private sector.

How Solar Power Can Help Coal Fired Power Plants Burn Less Coal

The sun can help coal fired power plants burn less coal by pre-heating the water used to make high pressure high temperature steam during periods when the sun is shining. In other words the sun would do part of the work of producing high pressure/ high temperature steam and in this manner the overall hybrid solar/coal power plant would use less coal than a coal only power plant would need to produce the same amount of electric power.

Corporate Sustainability Reporting Has Increased Dramatically

New figures released recently show that the number of companies and other organizations publicly disclosing their performance against a range of key sustainability indicators has risen markedly over the last year. The Global Reporting Initiative is now tracking of over 1000 organizations worldwide who issued sustainability reports based on the GRI G3 Guidelines in 2008 – the highest number ever recorded. The figure represents an increase of 46 per cent on the 2007 figure of 685.

World’s First Solar Gas Hybrid Power Plant Launched in Israel

Aora Solar Energy Company, formerly known as EDIG Solar, an Israeli solar power startup has launched a small 100kw hybrid solar/gas turbine system that will provide power to kibbutz Samar located in the southern desert of Israel. Besides concentrated solar energy, this hybrid power station can also run on other alternative fuels, including bio-gas, bio-diesel and natural gas. By adding the flexibility to run the micro-turbine using an alternative energy source besides the sun this hybrid flexibility the power plant can continue to produce electricity when sunlight is insufficient, such as at night or when it is cloudy.

Debunking The Spanish Study on The Dire Result of Green Jobs Creation – Updated January 1, 2011

By now, everybody has heard about the Studyt out of Spain that supposedly proves that Obama’s green jobs program is a loss cause that will hurt our economy. I think there are numerous flaws with that study. In this update, we have Spain’s response to his claims, proof that his data was falsified, an explanation of how the renewable energy investment did not have the major negative impact on business, in Spain, that his analysis was too simplistic to be applied in any real world model, and what most economists believe is the major cause of Spain’s high unemployment rate. I will also bring to light extremely relevant facts, that the study fails to mention or factor in to the study, and review the US’s history and results from past renewable energy investments. That’s right we have been investing in renewable energy for years.

Which Country Has The Greenest Stimulus Package? Updated June 1, 2009

The US is not the only country looking to renewable energy as a way to boost its economy by providing opportunities for increased investment, building low carbon efficiency into the infrastructure and creating millions of jobs. Australia, The European Union, South Korea, China, Germany, Japan, Italy, Canada, France and the United Kingdom
