SolarReserve, a U.S. developer of large-scale solar power projects, today announced completion of the assembly of the molten salt receiver panels that sits on top of the 540 foot solar power tower for its 110 megawatt (MW) Crescent Dunes Solar…

Duane Tilden‘s insight:

The project will utilize technology […] to capture and store the sun’s energy in order to deliver a firm electricity supply to Nevada, day or night, without the need to burn fossil fuels. The molten salt “receiver” is actually comprised of panels formed by hundreds of special alloy tubes which will be flowing with molten salt for energy absorption and storage. Once complete, the project will be capable of storing 10 hours of full load electricity production, enough to power 75,000 homes at peak electric demand periods, even after dark.

The project closed financing and initiated construction in September of 2011 and is scheduled to complete construction and start plant commissioning at the end of 2013, including first electricity production by the end of the year. The Crescent Dunes project has secured a 25-year power purchase agreement with NV Energy to sell 100 percent of the electricity output of the facility to serve homes across Nevada.  […]

“The energy storage capability of this technology solves the problem of intermittency typical of other renewable energy sources. Additionally, because of it high efficiency, this technology can generate almost twice as much energy as a comparably sized solar facility, including facilities powered by photovoltaic panels or by a direct steam tower.” said Kevin Smith, CEO of SolarReserve.

Wind and Neodymium

Jack Lifton’s research on mineral resources make him an important figure in projecting the future of energy. Lifton spotted the Lemhi Pass thorium reserve discoveries early on, Lifton has recently focused on world rare earth production, and as Lifton has pointed out, rare earths will play important roles in the future of energy. Lifton pointed out the importance of the rare earth element neodymium for the wind generation industry.

There’s another rare earth metal that’s critically important to our society—neodymium. In 1984, General Motors and Sumitomo developed the neodymium iron boron alloy for permanent magnets, which is the basis of all modern electric motors because it allows you to make a very small electric motor with the highest possible power density. Neodymium total world production is less than 20,000 tons. That may sound like a lot to you, but it’s tiny. And the fact is it’s recently been projected that a single wind turbine electric generator producing 1 megawatt of electricity requires one ton of neodymium.

The liquid fluoride thorium reactor (acronym LFTR; spoken as lifter) is a thermal breeder reactor that uses the thorium fuel cycle in a fluoride-based molten (liquid) salt fuel to achieve high operating temperatures at atmospheric pressure.

The LFTR is a type of thorium molten salt reactor (TMSR). […]

In a LFTR, thorium and uranium-233 are dissolved in carrier salts, forming a liquid fuel. Typical operation sees the liquid fuel salt being pumped between a critical core and an external heat exchanger, where the heat is transferred to a nonradioactive secondary salt, that then transfers its heat again to a steam turbine or closed-cycle gas turbine.[2]

This technology was first investigated at the Oak Ridge National Laboratory Molten-Salt Reactor Experiment in the 1960s. It has recently been the subject of a renewed interest worldwide.[3] Japan, China, the UK, as well as private US, Czech and Australian companies have expressed intent to develop and commercialize the technology.

German village delivers great green energy blueprint

Nations as diverse as North Korea and the United States have sent personnel to a tiny village in the east of Germany in a bid to understand its successful energy transformation.

Duane Tilden‘s insight:

…Feldheim is powered by a mix of 43 wind turbines, a woodchip-fired heating plant and a biogas plant that uses cattle and pig slurry as well as maize silage.

Local energy costs of 16.6 euro cents per kilowatt hour (kWh) are just a little more than half of the 27-30 cents Germans pay on average …

Feldheim’s rates are not far off those in Poland, which generates nearly all its electricity from carbon-intensive coal-fired plants.  Households there paid on average 14 cents per kWh in 2012, while those in the Czech Republic, which relies on nuclear for about a third of its power generation, paid about 15 cents per kWh.

DT:  Current electricity pricing in Canada is 6.3 to 11.8 cents/kWh (US$) & United States is 8 to 17 cents/kWh (US$) ~ wiki

Premier Global – DayStar Technologies, Inc. Premier Global Holdings announced that it has demonstrated an active energy material that is the first to combine solar energy generation and power storage into one cell at the molecular level.

Duane Tilden‘s insight:

Laboratory tests validated energy storage capacity exceeding 26 hours, zero degradation and a road map for significantly longer storage times with additional optimization. It is believed that this is the first time sunlight has been captured and simultaneously stored in a highly efficient, low-cost format.

This technology was developed at the University of British Columbia (UBC) and addresses the natural intermittency associated with sun and cloud cover thereby making solar power available anytime day or night. The home is only one application as the technology naturally lends itself as a built-in solution for anyone who uses electricity — including those 1.6 billion without electricity in the remote regions of China, India and Africa.

Whitecourt project is a first for the Calgary-based pipeline company

Duane Tilden‘s insight:

 The Whitecourt Recovered Energy Project captures exhaust heat from Alliance’s compressor stations northwest of Edmonton. The heat is transferred into a closed loop system and powers one of three 40,000-horsepower gas turbines at the site. The power system creates 14 megawatts of baseload electricity. It is expected to be tied into the provincial power grid in May 2013.

Largo, Florida based GDT Tek, a specialist in the use of the use of the Organic Rankin Cycle principal to generate electricity has entered into an agreement in principal to purchase 100% of a landfill gas to energy company.

Duane Tilden‘s insight:

According to the company its system has been proven through a long-term five year installation at a San Jose, California landfill, where waste heat captured from the generator’s engine exhaust and cooling systems is used to generate electricity which is then sold to the grid.

“This acquisition once completed will allow GDT Tek to install our Phoenix units at the landfill location and increase revenue by up to 20%,” explained Bo Linton, President of GDT Tek.

A growing number of energy storage start-ups are promoting the idea that the most economical, most expedient ways to store power revolves around harnessing the four elements of the ancient world: earth, air, water and fire.

Duane Tilden‘s insight:

Energy Cache, for instance, is developing a system that resembles a ski lift for gravel. Gravel is ferried uphill during the day by a series of buckets, and then dropped during peak power hours. The system essentially provides the drop in elevation nature left out.

An Energy Cache system could be erected at a large number of abandoned mining sites, where there is plenty of gravel and an existing grid connection,  […] Along with the physics, the company is analyzing algorithms to ensure smooth power deliver on demand for the power grid. …

Utilities have to engage with consumers and businesses to make the smart grid work.

Duane Tilden‘s insight:

“I had a smart meter, but I didn’t even know I had a smart meter,” said Dick.

Dick and a team of CU engineers are working on exactly this problem: how to inform people about their electricity use. The team is creating an online system called “EMPIRE” — EMpowering People In Reducing Energy consumption.  […]

Huston said that because Boulder’s smart grid was one of the first in the country, some of the technologies it used, such as fiber optic communication technology, turned out to be less ideal than hoped. The new two-way communication technology, installing smart meters for less than a quarter of the population and other features almost doubled the project’s cost within a year after it began. As of October 2012, the total costs were pushing $45 million.
