Aircraft maker Boeing Co., Etihad Airways, the oil company Total and others say they will work together on a program to develop an aviation biofuel industry in the United Arab Emirates. Etihad ran a 45-minute demonstration flight Saturday in a Boeing 777 partially powered by aviation biofuel produced in the UAE.
By replacing platinum with molybdenum in photoelectrochemical cells, scientists from two Swiss labs have developed a cheaper and scalable technique that can greatly improve hydrogen production through water splitting as a means of storing solar energy.
America's newest, most expensive coal-fired power plant is hailed as one of the cleanest on the planet, thanks to government-backed technology that removes carbon dioxide and keeps it out of the atmosphere. But once the carbon is stripped away, it will be used to do something that is not so green at all. It will extract oil.
For millions of homes, plants, wood and other types of “biomass” serve as an essential source of fuel, especially in developing countries, but their mercury content has raised flags among environmentalists and researchers. Scientists are now reporting that among dozens of sources of biomass, processed pellets burned under realistic conditions in China emit relatively low levels of the potentially harmful substance.
Researchers in Lyon, a French city famed for its cuisine, have discovered a quick-cook recipe for copious volumes of hydrogen that involves water, rock, aluminum oxide and extreme pressure. The breakthrough suggests a better way of producing the hydrogen that propels rockets and energizes battery-like fuel cells.
The solar panel installer SolarCity is beginning to address one of solar power's big drawbacks: The sun doesn't always shine. The solution: big battery packs that will provide backup power while lowering electric bills. The supplier: electric car maker Tesla Motors, whose CEO Elon Musk is also the chairman of SolarCity.
Scientists at The Univ. of Texas at Austin have developed a new method to estimate gas production from hydraulically fractured wells in the Barnett Shale. The approach, which uses a simple physics theory called scaling, is intended to help the energy industry accurately identify low- and high-producing horizontal wells, as well as accurately predict how long it will take for gas reserves to deplete in the wells.
The first trickle of fuels made from agricultural waste is finally winding its way into the nation's energy supply. But the full benefits of this fuel source remain many years away, and ethanol, which was meant to be a stop-gap until non-food sources of fuel were found, has been far more damaging to the environment than the government predicted.
According to a study published by scientists at the Potsdam Institute for Climate Impact Research, the strategy of assigning a price to global carbon nanotubes emissions could generate a revenue of $32 trillion over the 21st century, exceeding by far the $12 trillion of lost profits from fossil fuel owners.
A set of new building technologies introduced by an alliance of Swiss companies makes it possible to heat and cool buildings without the emission of carbon dioxide. One initial key element of the system is a hybrid collector, built into the roof construction, that serves as a photovoltaic system delivering both solar power and heat that is fed to an underground accumulator.
The Swiss Federal Institute of Technology in Lausanne’s new convention center, opening in April 2014, is being equipped with a glass façade composed of dye solar cells. The project, a world’s first for an exterior window, leverages the potential of dye-sensitive solar cells known as Graetzel cells, which are indifferent to the angle of incidence of light that hits them.
In waters off Long Beach, Seal Beach and Huntington Beach—some of the region's most popular surfing strands and tourist attractions—oil companies have used fracking at least 203 times at six sites in the past two decades. This discovery made from drilling records and interviews shows that offshore fracking is more widespread and frequent that state officials believed.
Materials in lithium ion battery electrodes expand and contract during charge and discharge. These volume changes drive particle fracture, which shortens battery lifetime. A group of scientists has quantified this effect for the first time using high-resolution 3D movies recorded using x-ray tomography at the Swiss Light Source.
Experts from the Univ. of Maryland and a leading university in Spain demonstrate in a new study which sectors could put the entire U.S. economy at risk when global oil production peaks. This multi-disciplinary team recommends immediate action by government, private and commercial sectors to reduce the vulnerability of these sectors.
New research from the National Renewable Energy Laboratory has quantified the potential impacts of increasing wind and solar power generation on operators of fossil-fueled power plants in the West. To accommodate higher amounts of wind and solar power on the electric grid, utilities must ramp down and ramp up or stop and start conventional generators more frequently to provide reliable power for their customers—a practice called cycling.
According to a recent study published by the National Science Foundation (NSF), businesses spent more on research and development (R&D) in 2011 than they did in 2010. The figures revealed that during 2011, companies in manufacturing industries performed $201 billion, or 68%, of domestic R&D.
Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of water. Engineers in Spain have performed a computer simulation to determine the optimal configuration of a system produced by a Norwegian company to enable it to extract the maximum amount of energy from any given current.
According to research published this week drilling and fracking for natural gas don't seem to spew immense amounts of the greenhouse gas methane into the air, as has been feared. The study, mostly funded by energy interests, doesn't address other fracking concerns about potential air and water pollution, but does generally with government estimates.
Kerogen is a mixture of organic chemical compounds in sedimentary rocks that is a key intermediate of oil and natural gas. After five years of research, researchers in China have developed a terahertz time-domain spectroscopy method that effectively detects the generation of oil and gas from kerogen without contact or destruction of the sample material.
In the 1980s and 1990s, hydroelectric development stagnated as environmental groups lobbied against it and a long regulatory process required years of environmental study. But for the first time in decades, power companies are proposing new projects to take advantage of government financial incentives, policies that promote renewable energy over fossil fuels and efforts to streamline the permit process.
Farmers who grow corn and soybeans can take advantage of government price support programs and crop insurance, but similar programs are not available for those who grow biomass crops. A new study recommends a framework for contracts between growers and biorefineries to help spell out expectations and designate who will assume the risks and costs.
Toyota has two important vehicles coming in 2015: the next-generation Prius hybrid and the company's first hydrogen fuel cell car. Satoshi Ogiso, a top Toyota engineer who helped develop the original Prius 20 years ago, said Wednesday that the new Prius will get significantly better fuel economy...
A new Department of Energy study conducted by the National Renewable Energy Laboratory indicates that by 2025 wind and solar power electricity generation in the western U.S. could become cost-competitive without federal subsidies, if new renewable energy development occurs in the most productive locations. The report is now available.
A new facility at Idaho National Laboratory is helping nuclear power plant operators like Duke Energy embark on an upgrade projects for their control rooms. The new Human System Simulation Laboratory (HSSL) is a full-scale virtual nuclear control room that can test the safety and reliability of proposed technology replacements before they are implemented in commercial nuclear control rooms.
The European Commission's Joint Research Centre (JRC) and the U.S. Dept. of Commerce’s National Institute of Standards and Technology (NIST) this week agreed to expand their current scientific cooperation to include new areas of research, such as energy, health care and clinical measurements, and food safety and nutrition.
