Exxon's CEO: Climate, energy fears overblown

June 27, 2012 12:58 pm | by Jonathan Fahey, AP Energy Writer | News | Comments

In a speech Wednesday, ExxonMobil CEO Rex Tillerson said fears about climate change, drilling, and energy dependence are overblown. He acknowledged that burning of fossil fuels is warming the planet, but said society will be able to adapt and dependence on other nations for oil is not a concern as long as access to supply is certain.

Bringing down the cost of fuel cells

June 22, 2012 5:56 am | News | Comments

Engineers at the University of Wisconsin-Milwaukee have identified a catalyst that provides the same level of efficiency in microbial fuel cells as the currently used platinum catalyst, but at 5% of the cost. Since more than 60% of the investment in making microbial fuel cells is the cost of platinum, the discovery may lead to much more affordable energy conversion and storage devices.

Ocean energy development with less sound

June 21, 2012 3:48 am | News | Comments

The rise of ocean infrastructure development to tap energy sources such as tides, offshore wind, and natural gas will require more pile driving. But pile driving creates loud, underwater booms that can harm fish and other marine animals. New research indicates that if an individual blow to a pile rises above a particular sound level, fish can be irreparably harmed. This finding has led scientists to recommend the first-ever sound threshold for pile driving based on fish responses.

Cheaper fuel from algae

June 20, 2012 8:11 am | News | Comments

Scientists have revealed an advance toward a long-sought economical process that could turn algae into a sustainable source of biodiesel and other "green" fuels. The researchers describe the efforts toward a simple process that would extract the fatty molecules called lipids used to make biodiesel from algae and transform them into usable fuel in one fell swoop.

NREL helps supersize butanol production

June 20, 2012 7:29 am | News | Comments

The idea of "supersizing" is no longer embraced when it comes to what we eat. But when it comes to creating renewable fuels, supersizing can be a very good thing. Recently, a team of scientists from Cobalt Technologies assembled at the National Renewable Energy Laboratory to supersize their process for making renewable butanol.

Textured surface may boost power output of thin silicon solar cells

June 13, 2012 10:18 am | by David Chandler, MIT News Office | News | Comments

Highly purified silicon represents up to 40% of the overall costs of conventional solar-cell arrays—so researchers have long sought to maximize power output while minimizing silicon usage. Now, a team at Massachusetts Institute of Technology has found a new approach that could reduce the thickness of the silicon used by more than 90% while still maintaining high efficiency.

Green fuel from carbon dioxide and hydrogen?

June 13, 2012 8:19 am | News | Comments

A research team at the Freiburg Materials Research Center in Germany has developed a new system for producing methanol that uses carbon dioxide and hydrogen. The key to helping make their process more efficient is the use of the metal oxides of copper, zinc, and zirconium dioxide as catalysts, enabling the reaction to happen at lower temperatures. Ionic salts may also play a role.

New energy source for future medical implants

June 13, 2012 3:49 am | by Anne Trafton, MIT News Office | News | Comments

Massachusetts Institute of Technology engineers have developed a fuel cell that runs on the same sugar that powers human cells: glucose. This glucose fuel cell could be used to drive highly efficient brain implants of the future, which could help paralyzed patients move their arms and legs again.

Study: U.S. must encourage development of Canadian oil sands

June 12, 2012 5:03 am | News | Comments

To successfully reduce the United States' dependence on fuels from outside North America, the government must pursue policies that foster the diversion of Canadian oil sands crude to U.S. Gulf Coast refineries, according to a new study by Rice University's Baker Institute for Public Policy.

Study: Environmental benefit of biofuels is overestimated

June 10, 2012 12:20 pm | News | Comments

A recent study by two scientists reveals that calculations of greenhouse gas emissions from bioenergy production are neglecting crucial information about carbon dioxide and nitrogen emissions that has led to the overestimation of the benefits of biofuels compared to fossil fuels. They claim the life cycle analysis models of bioenergy production are flawed as a result.
