Graphene Supercapacitors: The End Of Batteries? | EarthTechling

supercapacitor grapheneIf these UCLA researchers are right – and we might find out pretty soon – energy storage could be in for a big change.

Richard Kaner and his graduate student Maher El-Kady have been trumpeting graphene micro-supercapacitors that would combine the very fast charge and discharging capabilities of supercapacitors – hundreds of times faster than batteries – with the high energy density of batteries. Now the researches say they have demonstrated a scalable fabrication process that could make their supercapacitors cheap to produce while expanding the possibilities for their use.

Edgeland Residence: a modern take on the Native American Pit House

Edgeland Residence takes up an area of 1400 square feet (130 square meters)Edgeland Residence is a modern dwelling designed by the Bercy Chen Studio which sees the company rehabilitating land once considered unsuitable for occupation. Claimed to set a new standard for sustainability, it draws inspiration from the Native American Pit House, and is designed to impact the environment as little as possible.

$10 million grant for clean power research

Southwest Research Institute has been awarded almost $10 million from the U.S. Department of Energy to develop new and cheaper ways of processing the carbon dioxide removed from power plant emissions, to keep it from polluting the air. Along with sulfur dioxide and nitrogen dioxide, carbon dioxide is a pollution-causing byproduct of burning fossil fuel, and power plants are a major source of those emissions.

Power problems might be worse next year

A prolonged drought, looming environmental rules and shortcomings in the incentives for building new power plants could cause even more problems with Texas’ electric grid in the next year. A number of Texas power plants may need to cut back operations or shut down completely if the state’s severe drought continues into the fall, as water levels in many plant cooling reservoirs continue to drop, said Kent Saathoff, vice president of system planning and operations for the Electric Reliability Council of Texas. Although a municipal utility provides electricity in San Antonio, it is part of ERCOT, so high power demand, conservation advisories and potential rolling blackouts affect its electric customers along with others in the state. In July the Environmental Protection Agency issued the final version of its Cross-State Air Pollution Rules, which require reductions in nitrogen oxide, sulfur dioxide and particulate emissions that cross state lines and contribute to ground-level ozone. The Railroad Commission of Texas, which oversees lignite mining operations in Texas, on Tuesday asked Attorney General Greg Abbott to sue the EPA over the rule, saying it fails to take into account economic effects and could harm both the lignite coal industry and power grid reliability.

Energy conservation urged this afternoon

The Texas power grid operator asked the public to conserve energy until 7 p.m. today because power levels were short.
The Electric Reliability Council of Texas, which controls most of the state’s power grid, declared an emergency again Tuesday but has avoided rolling outages.
ERCOT had warned that demand could exceed supply this week as schools and universities reopened and temperatures remain high across the state.
warned this week could be tight as schools reopen.
ERCOT is urging businesses, school districts, government agencies and individuals to watch their power use between 3 p.m. and 7 p.m. weekdays.

Waste Management aims to turn trash into energy

By any measure, Waste Management is a giant in the U.S. garbage collection and recycling business, but its future might lie in a different service: turning trash into energy. If we lose the waste, we’ve certainly lost the business, said Carl Rush, vice president of the company’s organic growth group, the chief vehicle for its energy investments. The shift in thinking comes at a time when U.S. landfill collections are hitting a plateau as Americans recycle more, consumer products makers reduce packaging and many large corporations adopt “zero waste” goals. Demand for renewable energy and fuels also is increasing, in response both to regulations requiring them and to public concerns about the nation’s reliance on fossil fuels and their environmental impact. Waste Management also has its own pilot plant in Oklahoma that converts landfill gas to diesel fuel for its trash collection trucks. […] it’s in a joint venture with Linde in an Altamont, Calif., plant that turns landfill gas into liquefied natural gas and powers 1,000 garbage trucks there. The company now has a portfolio of nearly 30 acquisitions, joint ventures and investment projects at various stages of development.
