Does America Have a Hydrogen-Powered Future?

Using rising gas prices as the background, Knight Ridder's Robert Boyd is taking a look at the future of hydrogen-powered vehicles:

But the cost of delivering a hydrogen-powered car to market is a major obstacle, as is the cost of converting tens of thousands of service stations from gasoline to hydrogen. Despite its abundance in nature, producing hydrogen in a usable form costs three to four times more than refining crude oil into gasoline.

What's more, while burning hydrogen is non-polluting, generating the electric power needed to produce it, say by splitting water (H2O) into hydrogen and oxygen, could produce more pollution.

Scientists are experimenting with enlisting living organisms, such as bacteria and algae, that can make hydrogen from sunlight and are seeking ways to generate hydrogen from nuclear and solar power. The costs of such technologies are still unknown.

The higher the cost of gasoline, however, the more competitive hydrogen will be, said Thomas Sheahen, an analyst at the National Renewable Energy Laboratory's Washington office.

"At most, the cost (of hydrogen) should equal the cents-per-mile cost of gasoline," said Steve Chalk, the Energy Department's National Hydrogen Program manager. "I hope it will be lower."

Fluor Invests in NuScale

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

An Ohio School Board Is Working to Save Nuclear Plants

Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Wednesday Update

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
