Cool Roofs Have Water Saving Benefits Too
October 20, 2017 01:42 PM - DOE/Lawrence Berkeley National Laboratory

The energy and climate benefits of cool roofs have been well established: By reflecting rather than absorbing the sun’s energy, light-colored roofs keep buildings, cities, and even the entire planet cooler. Now a new study by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found that cool roofs can also save water by reducing how much is needed for urban irrigation.

Impact of Amazonian Hydropower is 'Significantly Underestimated', Study Finds

The environmental impact of hydropower generation in the Amazon may be greater than predicted, according to new University of Stirling research.

Scientists Solve a Magnesium Mystery in Rechargeable Battery Performance

Rechargeable batteries based on magnesium, rather than lithium, have the potential to extend electric vehicle range by packing more energy into smaller batteries. But unforeseen chemical roadblocks have slowed scientific progress.

Separating methane and CO2 will become more efficient
October 18, 2017 10:18 AM - KU Leuven

To make natural gas and biogas suitable for use, the methane has to be separated from the CO?. This involves the use of membranes: filters that stop the methane and let the CO? pass through. Researchers at KU Leuven have developed a new membrane that makes the separation process much more effective.

A New Way to Harness Wasted Methane
October 17, 2017 11:54 AM - Massachusetts Institute of Technology

Methane gas, a vast natural resource, is often disposed of through burning, but new research by scientists at MIT could make it easier to capture this gas for use as fuel or a chemical feedstock.

New biomass plant to cut Simon Fraser University's greenhouse gases by two-thirds
October 17, 2017 08:16 AM - Simon Fraser University

A new project at Simon Fraser University (SFU) will soon divert wood waste from the landfill and help reduce greenhouse gasses at the University.

SFU and SFU Community Trust are collaborating with Corix Multi-Utility Services Inc., on a $33-million community-based biomass project called the Burnaby Mountain District Energy Utility (BMDEU).

Byproducts from biofuel focus of PNNL and WSU partnership
October 12, 2017 12:23 PM - Pacific Northwest National Laboratory

Researchers at the Department of Energy's Pacific Northwest National Laboratory have created a continuous thermo-chemical process that produces useful biocrude from algae. The process takes just minutes and PNNL is working with a company which has licensed the technology to build a pilot plant using the technology.

Will metal supplies limit battery expansion?
October 11, 2017 05:27 PM - Massachusetts Institute of Technology

The dramatic rise in production of electric vehicles, coupled with expected growth in the use of grid-connected battery systems for storing electricity from renewable sources, raises a crucial question: Are there enough raw materials to enable significantly increased production of lithium-ion batteries, which are the dominant type of rechargeable batteries on the market?

Making renewable power more viable for the grid
October 11, 2017 05:25 PM - Massachusetts Institute of Technology

Wind and solar power are increasingly popular sources for renewable energy. But intermittency issues keep them from connecting widely to the U.S. grid: They require energy-storage systems that, at the cheapest, run about $100 per kilowatt hour and function only in certain locations.
