Transporting methane from gas wellheads to market provides multiple opportunities for this greenhouse gas to leak into the atmosphere. Now, an international team of researchers has taken the first step in converting methane directly to electricity using bacteria, in a way that could be done near the drilling sites.

"Currently, we have to ship methane via pipelines," said Thomas K. Wood, holder of the biotechnology endowed chair and professor of chemical engineering, Penn State. "When you ship methane, you release a greenhouse gas. We can't eliminate all the leakage, but we could cut it in half if we didn't ship it via pipe long distances."

The researchers' goal is to use microbial fuel cells to convert methane into electricity near the wellheads, eliminating long-distance transport. That goal is still far in the future, but they now have created a bacteria-powered fuel cell that can convert the methane into small amounts of electricity.

The report, in Genome Announcements, comes after almost seven years of research, according to Dr. Tim Devarenne, AgriLife Research biochemist and principal investigator in College Station. In addition to sequencing the genome, other genetic facts emerged that ultimately could help his team and others studying this green microalga further research toward producing algae and plants as a renewable fuel source.

"This alga is colony-forming, which means that a lot of individual cells grow to form a colony. These cells make lots of hydrocarbons and then export them into an extracellular matrix for storage," Devarenne said. "And these hydrocarbons can be converted into fuels -- gasoline, kerosene and diesel, for example, the same way that one converts petroleum into these fuels."

France is moving forward on renewables, as the European Commission has approved a plan for Europe’s second-largest economy to contribute another 17 gigawatts (GW) of clean power to its infrastructure. If this plan comes to fruition, France could almost double its combined current wind and solar power capacity.

And that decision dwarfs the Commission’s approval earlier this year of a request from France to add about 2.6 GW of renewables, mostly from solar and hydropower. Known during the postwar era for De Gaulle and nuclear, France is embarking on the path of Macron and renewables.

Researchers have uncovered the exact mechanism that causes new solar cells to break down in air, paving the way for a solution.

Solar cells harness energy from the Sun and provide an alternative to non-renewable energy sources like fossil fuels. However, they face challenges from costly manufacturing processes and poor efficiency - the amount of sunlight converted to useable energy.

Light-absorbing materials called organic lead halide perovskites are used in a new type of solar cells that have shown great promise, as they are more flexible and cheaper to manufacture than traditional solar cells constructed of silicon.

Led by VTT Technical Research Centre of Finland, the COMBO-CFB project has developed a new innovative concept to increase solar energy production in the energy system. According to this research, the concept can reduce fuel consumption and emissions stressing the climate by more than 33 per cent. The concept is based on the combination of concentrated solar power (CSP) technology and a traditional power plant process into a hybrid plant which produces electricity on the basis of consumption.

Every Canadian has a stake in helping to shape the country’s energy systems. But how do we make sense of the ever-increasing and complex information about issues such as pipeline safety, environmental impacts and economic benefits?

Researchers from the University of Antwerp and KU Leuven have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.

The U.S. wind energy industry experienced its fastest first-quarter growth since 2009, installing 2,000 new megawatts of capacity — enough to power about 500,000 homes — on its way to producing 5.5 percent of the country’s electricity.

The American Wind Energy Association (AWEA) also reported that another 21,000 megawatts of wind energy capacity is now under construction or in advanced development — enough to power an additional 5 million average U.S. homes. The AWEA said that 908 utility-scale wind turbines were erected in the first quarter of 2017, driving a nearly four-fold increase in wind energy growth over the first quarter of 2016. Forty-one U.S. states — most recently Rhode Island and North Carolina — now have utility-scale wind power projects. Texas is by far the wind energy leader in the U.S., with a wind power capacity of 21,000 megawatts.

Expanding its work in renewable energy, the National Center for Atmospheric Research (NCAR) is launching a three-year project to develop specialized forecasts for a major wind and solar energy facility in Kuwait.

"We're putting our expertise and technology to work around the world," said NCAR Senior Scientist Sue Ellen Haupt, the principal investigator on the project. "This landmark project meets our mission of science in service to society."

A recent discovery by Sandia National Laboratories researchers may unlock the potential of biofuel waste — and ultimately make biofuels competitive with petroleum.

Fuel made from plants is much more expensive than petroleum, but one way to decrease the cost would be to sell products made from lignin, the plant waste left over from biofuel production.

Lignin typically is either burned to produce electricity or left unused in piles because no one has yet determined how to convert it into useful products, such as renewable plastics, fabrics, nylon and adhesives. The electricity isn’t even available to the general public; it’s only used by companies that create large amounts of lignin, like pulp and paper manufacturers. Now Sandia scientists, working with researchers from Lawrence Berkeley National Laboratory at the Joint BioEnergy Institute, have decoded the structure and behavior of LigM, an enzyme that breaks down molecules derived from lignin.
