New carbon dioxide-removing catalyst can take the heat

May 24, 2012 4:13 am | News | Comments

The current method of removing the greenhouse gas carbon dioxide from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that has developed an entirely new catalyst for separating out and capturing carbon dioxide, one that mimics a naturally occurring catalyst operating in our lungs.

NREL simulates shade conditions in repeatable test for solar arrays

May 15, 2012 8:25 am | News | Comments

The National Renewable Energy Laboratory has released a new repeatable test protocol that simulates real shade conditions and can predict with much greater precision the effects of shade on a solar array. The new test demonstrated that under heavy shading conditions the use of microinverters instead of typical string inverters can help mitigate the impacts of shade by improving system performance by more than 12%.

A new look at prolonged radiation exposure

May 15, 2012 3:42 am | by Anne Trafton, MIT News Office | News | Comments

A new study from Massachusetts Institute of Technology scientists suggests that the guidelines governments use to determine when to evacuate people following a nuclear accident may be too conservative. The study found that when mice were exposed to radiation doses about 400 times greater than background levels for five weeks, no DNA damage could be detected.

From soil microbe to super-efficient biofuel factory?

May 3, 2012 9:20 am | News | Comments

Lawrence Berkeley National Laboratory scientists are exploring whether a common soil bacterium can be engineered to produce liquid transportation fuels much more efficiently than the ways in which advanced biofuels are made today. The process would be powered only by hydrogen and electricity. The goal is a biofuel—or electrofuel, as this new approach is called—that doesn’t require photosynthesis.


Study: Clean energy scale-up needs reality check

May 1, 2012 5:30 pm | by Mark Golden, Precourt Institute for Energy at Stanford University | News | Comments

In a post-Solyndra, budget-constrained world, the transition to a decarbonized energy system faces great hurdles. Overcoming these hurdles will require smarter and more focused policies. Two Stanford writers outline their visions in a pair of analyses.

Student-devised process would prep Chinese shale gas for sale

May 1, 2012 7:18 am | News | Comments

A team of Rice University students recently fulfilled a challenge to economically turn shale gas produced in China into a range of useful, profitable and environmentally friendly products. In building its plan, the team had to deal not only with processing what's known as "sour gas" straight out of the wellhead, but also had to come up with a solid budget for the construction and profitable operation of the plant as well as a strategy to protect the environment.
