The TERRA program seeks to develop technologies that can increase the precision, accuracy and throughput of energy crop breeding to enable predictive algorithms for plant growth, more detailed measurements of plant physiology and more sophisticated bioinformatics for gene discovery and trait association. Up to $30 million is being made available for the program to develop automated, predictive and systems-level approaches to enable the quick and easy identification of traits that can be leveraged to increase biomass yield through accelerated breeding cycles.
The funding opportunity is open to individuals, domestic entities, foreign entities, and consortium entities. APRA-E is expected to make between five and 10 awards under this funding opportunity. The period of performance for funding agreements cannot exceed 48 months. Applications are encouraged for ideas that require proof-of-concept research and development, and for those for which some proof-of-concept demonstration already exists.
ARPA-E is seeking multidisciplinary teams to leverage advancements in automation, sensor technologies, computational analytics and low-cost nucleotide sequencing. These teams would develop innovative phenotyping systems that enable new predictive algorithms for plant growth and more detailed measurements for plant physiology and more sophisticated bioinformatics pipelines for gene discovery and trait association.
ARPA-E's mission is to fund applied R&D for disruptive, breakthrough energy technologies that are too risky for the private sector, but create the foundation for entirely new industries if successful. The agency does not support technology development over extended periods of time and does not fund basic research but rather, supports the initial creation of technology.
The deadline for concept papers is set for Nov. 17. ARPA-E has not yet set a deadline for full application packages. (Source: ARPA-E, 6 Oct., 2014) Contact: ARPA-E, Cheryl Martin, Acting Director, email@example.com, http://arpa-e.energy.gov

"We deserve more than political posturing and moves as antiquated as the incandescent bulb. Right now, a convergence of environmental, economic and technological forces is transforming the global energy landscape. Just last month, the International Energy Agency (IEA) projected that renewable energy sources would eclipse nuclear and gas generation by 2016, and provide a quarter of the world's energy supply by 2018. Renewable energy is unequivocally a major component of the energy landscape.
"With the global rise of renewables, clean energy has become an inextricable component of energy science and engineering. Programs in sustainability, renewable energy, smart grid, and energy efficiency have emerged at major universities all over the U.S. These programs popped up as fields like mechanical and electrical engineering identified climate change as a key challenge facing humanity. Engineers have always sought to apply scientific knowledge to overcome technical challenges and ensure human safety and progress. Now, more than ever, academic researchers are passionately seeking solutions to address global warming.
"As top engineers and scientists have acknowledged the need to address the threat of climate change, so too have aspiring young scientists and engineers. Sustainability has become part of innovative educational programs across the country. Today, it is rare to see a science classroom without a miniature solar panel or wind turbine on its shelves. Why? Because students of all ages are compelled by the chance to design the next device or system that will help us overcome the challenges resulting from climate change. Students' passion for clean energy helps them endure difficult subjects like math and science, making the U.S. more competitive internationally. We owe it to these students to keep up the pace of clean energy education and research. Government funding agencies like ARPA-E and the DOE have a direct influence on science and engineering departments all over the country.
"Cutting these agencies has a ripple effect that hurts students, professors and other educators across the nation. Whether our elected leaders like it or not, researchers and academics will continue to explore the potential of the new energy frontier. The question is, will the government promote their efforts, or squander the momentum thousands of talented Americans have built up over many years of dedicated work?"

The Printed Integral Battery Project is part of a portfolio of research within the PARC Energy Technology Program aimed at developing practical solutions to make clean and abundant energy available across a wide range of applications. This includes a focus on improving energy storage for EVs, consumer electronics, and electric grid support through better ways to make, monitor, and manage batteries.
The conventional lithium-ion battery manufacturing process requires that the two halves of a battery be made in two separate steps, and then combined together in a third step -- each step adding cost that contributes to the high price of the final product. PARC's Printed Integral Battery deposits the entire battery cell-cathode, separator, anode in one single pass. PARC's CoEx technology allows multiple materials to be deposited simultaneously while still maintaining fine features in the finished product.
Implementing CoEx for solar, PARC has partnered with a solar company for mass manufacturing of silicon solar cell gridlines, and is currently seeking partnerships with battery manufacturers to use CoEx as a drop-in replacement for conventional electrode deposition equipment that can improve the performance of current battery chemistries by as much as 30 percent.

The amount of natural gas flared or vented from oil wells globally is equal to one-third of the amount of petroleum used in the U.S. each year. And every molecule of methane vented to the atmosphere in that process has the global-warming capacity of 12 molecules of carbon dioxide. A consortium of scientists says that if the wasted gas can be turned into a liquid, then it can be piped along with the petroleum to refineries where it can be turned into diesel fuel.
The consortium's proposal to develop a microbe that eats methane won a $4.8 million Advanced Research Projects Agency (ARPA-E) award from DOE. NREL's award was announced as one of 66 OPEN 2012 projects, which focus on a wide array of technologies, including advanced fuels.
The University of Washington is taking the lead and focusing on genetically modifying the microbes. NREL will be in charge of fermentation to demonstrate the productivity of the microbes, both the natural organism and the genetically-altered varieties. NREL will also extract the lipids from the organisms and analyze the economic potential of the plan.
A third partner, UK-headquartered Johnson-Matthey will produce the catalysts that turn the lipids in the methane into fuel. Lanza Tech, a pioneer in waste-to-fuels technology, has signed on to commercialize the bench-scale plan if it is successful.
The end product would be a fuel intermediate that then could be piped to a refinery for final processing into diesel or jet fuel.(Source: NREL, Environmental Expert, Jan. 3, 2013) Contact: LanzaTech, Dr. Jennifer Holmgren, CEO, (630) 439-3050, www.lanzatech.com; NREL, www.nrel.gov

Superconducting materials carry electricity without any electrical resistance, resulting in no energy lost during transport. However, wind turbines generate magnetic fields, which results in magnetic flux lines -- essentially the pull of magnetism -- running through and moving within superconducting wires. These flux lines interfere with the wires' ability to transport electricity, lowering its performance.
The ultimate goal for the three-year project is to improve the performance of superconducting wire used in wind turbines by 400 percent.

"(Mitt Romney's) Republican VP pick Paul Ryan's fiscal year 2013 budget proposal would have removed tax incentives for wind and solar development, while retaining $40 billion in tax breaks to oil and gas companies over the next decade. Such an approach is consistent with Ryan's support from oil tycoons David and Charles Koch, as well as his denial of Global Warming.
"Ryan has voted to prevent the Environmental Protection Agency from limiting greenhouse pollution, to eliminate White House climate advisers, to block the U.S. Department of Agriculture from preparing for climate disasters like the drought that devastated his home state, and to eliminate the Department of Energy Advanced Research Projects Agency (ARPA-E).
"As Chairman of the House Budget Committee, Paul Ryan has produced a series of proposed budgets dubbed The Path to Prosperity that make sharp changes to U.S. taxation and spending policy. Core to Ryan's budgets are the reduction of income taxes for upper-income earners as well as corporate, investment and capital gains taxes, all of which would benefit the wealthiest Americans.
"In order to partially compensate for the budget shortfall this would create, Ryan proposes imposing a consumption tax, increasing tax rates for lower- and middle-income earners and removing some tax loopholes, as well as slashing a variety of federal programs and privatizing others.
"Within this larger strategy is a hostility to programs that would enable reductions in greenhouse gas emissions, as well as federal energy research and development (R&D), which Ryan states should be left to the private market.
"All in all, Ryan's proposed 2013 budget would cut U.S. federal energy programs by $3 billion in fiscal year 2013 alone, reducing the U.S. Department of Energy (DOE) budget to 20% of 2012 levels over the next five years. This would include cuts to R&D programs.
"Ryan's plan stands in sharp contrast to the budget proposal by incumbent President Barack Obama (D), which includes an extension of the Section 1603 Treasury Grant Program, as well as increased funding for a variety of clean energy programs, including the DOE's SunShot program and federal energy R&D programs. In Congressman Paul Ryan (R-Wisc.), Mitt Romney has chosen a Vice-Presidential candidate who has proposed gutting federal renewable energy funding, maintaining oil and gas subsidies, and blocking the U.S. Environmental Protection Agency (EPA) from regulating greenhouse gases."

Iron-air batteries have been around for decades -- they saw a surge in interest during the 1970s energy crisis, but suffered from a crippling problem: a competing chemical reaction of hydrogen generation that takes place inside the battery (known as hydrolysis) sucked away about 50 percent of the battery's energy, making it too inefficient to be useful.
Narayan's team managed to reduce the energy loss down to 4 percent by adding a very small amount of bismuth sulfide into the battery. Bismuth (which happens to be part of the active ingredient in Pepto-Bismol and helps give the pink remedy its name) shuts down the wasteful hydrogen generation.
Narayan's team included fellow USC researchers G. K. Surya Prakash, Aswin Manohar, Souradip Malkhandi, Bo Yang, Robert Aniszfeld, Chenguang Yang, Phong Trinh; and Andrew Kindler of NASA's Jet Propulsion Laboratory.
