DOE Outlines Research Needed to Improve Solar Energy Technologies

To help achieve the Bush administration’s goal of increased use of solar and other renewable forms of energy, the Department of Energy’s Office of Science has released a report describing the basic research needed to produce "revolutionary progress in bringing solar energy to its full potential in the energy marketplace."
"This report demonstrates the important contribution the entire scientific community can make to the development of new sustainable energy resources," [Director of DOE's Office of Science Raymond] Orbach said. "Science and basic research can and must play a key role in addressing the energy security needs of our nation."

Every hour more energy from sunlight strikes the Earth than is consumed on the planet in a year. Yet today, solar electricity provides only approximately one thousandth of the total electricity supply. The report notes that a "huge gap between our present use of solar energy and its enormous undeveloped potential defines a grand challenge in energy research" and that "sunlight is a compelling solution to our need for clean, abundant sources of energy in the future."

The report notes that progress in the proposed research could lead to: artificial "molecular machines" that turn sunlight into chemical fuel; "smart materials"” based on nature’s ability to transfer captured solar energy with no energy loss; self-repairing solar conversion systems; devices that absorb all the colors in the solar spectrum for energy conversion, not just a fraction; far more efficient solar cells created using nanotechnologies; and new materials for high-capacity, slow-release thermal storage.

Fluor Invests in NuScale

By
You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Wednesday Update

By
From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

By
Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...
