One way of storing solar energy is to transform the energy directly into a fuel. Researchers at Uppsala Univ. have shown a reaction which makes the process of creating fuel from solar energy more efficient and less energy demanding. Solar energy is abundant. In one hour, the Earth receives as much energy from the sun as humankind uses in a whole year.
Scientists at the Univ. of York are part of a research team which has found that a recently discovered family of enzymes can degrade resistant forms of starch. Earlier research established that the enzymes, lytic polysaccharide monooxygenases (LPMOs), are able to degrade hard-to-digest biomass into its constituent sugars.
A team of Univ. of Wisconsin-Madison engineers has developed a new tool to help plot the future of solar fuels. In a paper recently published in Energy & Environmental Science, a team outlined a tool to help engineers better gauge the overall yield, efficiency and costs associated with scaling solar-fuel production processes up into large-scale refineries.
Scientists have identified synthetic materials that may purify ethanol more efficiently and greatly improve the separation of long-chain hydrocarbons in petroleum refining. The results show that predictive modeling of synthetic zeolites is highly effective and can help solve some of the most challenging problems facing industries that require efficient ways to separate or catalyze materials.
Many of today's most promising renewable energy technologies rely upon catalysts to expedite the chemical reactions at the heart of their potential. Catalysts are materials that enhance chemical reactions without being consumed in the process. For over a century, engineers across the world have engaged in a near-continual search for ways to improve catalysts for their devices and processes.
Stacking perovskites onto a conventional silicon solar cell dramatically improves the overall efficiency of the cell, according to a new study led by Stanford Univ. scientists. The researchers describe their novel perovskite-silicon solar cell in Energy & Environmental Science.
A new version of an online tool created by Argonne National Laboratory will help biofuels developers gain a detailed understanding of water consumption of various types of feedstocks, aiding development of sustainable fuels that will reduce impact on limited water resources.
Windows allow brilliant natural light to stream into homes and buildings. Along with light comes heat that, in warm weather, we often counter with energy-consuming air conditioning. Now scientists are developing a new kind of "smart window" that can block out heat when the outside temperatures rise. The advance could one day help consumers better conserve energy on hot days and reduce electric bills.
A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.
A team from the University of Arizona and eight Southwestern electric utility companies has built a pioneering web portal that provides insight into renewable energy sources and how they contribute to the region’s electricity grid.
A new catalytic process is able to convert what was once considered biomass waste into lucrative chemical products that can be used in fragrances, flavorings or to create high-octane fuel. A team of researchers from Purdue Univ.'s Center for Direct Catalytic Conversion of Biomass to Biofuels, or C3Bio, has developed a process that uses a chemical catalyst and heat to spur reactions that convert lignin into valuable chemical commodities.
Stanford University's Precourt Institute for Energy, Precourt Energy Efficiency Center and TomKat Center for Sustainable Energy have awarded eight seed grants totaling about $1.5 million for promising new research in clean technology and energy efficiency.

During the 2014 R&D 100 Awards event, R&D Magazine expanded the banquet to hold four technology panels during the day. The last panel of the day focused on energy/environmental solutions and the innovation behind four R&D 100-winning technologies and the complexity of bringing such technologies to the market.
A groundbreaking research project by the GW4 Alliance aims to clean up water from a Cornish tin mine, using algae to harvest the precious heavy metals and produce biofuel at the same time. GW4 brings together the South West and Wales’ four leading, research-intensive universities: Bath, Bristol, Cardiff and Exeter.
Scientists at the National Physical Laboratory have developed a new method for detecting defects in solar cells using a technique called compressed sensing. Solar panels are being rapidly deployed across the world as costs fall and the need for sustainable, low-carbon energy grows. Being able to effectively characterize solar cells is a key factor in quality control during manufacturing and understanding their long-term behavior.
Two years ago, researchers at the Joint BioEnergy Institute engineered E. coli bacteria to convert glucose into significant quantities of methyl ketones, a class of chemical compounds primarily used for fragrances and flavors, but highly promising as clean, green and renewable blending agents for diesel fuel. Now, after further genetic modifications, they have managed to dramatically boost the E.coli’s methyl ketone production 160-fold.
As solar panels become less expensive and capable of generating more power, solar energy is becoming a more commercially viable alternative source of electricity. However, the photovoltaic cells now used to turn sunlight into electricity can only absorb and use a small fraction of that light, and that means a significant amount of solar energy goes untapped. A new technology epresents a first step toward harnessing that lost energy.
The use of renewable energy in the U.S. could take a significant leap forward with improved storage technologies or more efforts to “match” different forms of alternative energy systems that provide an overall more steady flow of electricity. Historically, a major drawback to the use and cost-effectiveness of alternative energy systems has been that they are too variable. This lack of dependability is costly and inefficient.
Farmers interested in bioenergy crops now have a resource to help them determine which kind of bioenergy crop would grow best in their regions and what kind of harvest to expect. Researchers at the Univ. of Illinois have published a study identifying yield zones for three major bioenergy crops.
The editors of R&D Magazine have announced the opening of the 2015 R&D 100 Awards entry process.
