Lightening Soldiers’ Loads by Lifting PV Cells onto Flexible Surfaces

Two thousand years ago, Roman legionnaires lugged 100-pound packs into battle. A lot has changed since then, but technology hasn’t really reduced an infantryman’s load. On the battlefield, mobility is critical—but a typical, modern Marine may shoulder an 80-pound backpack containing 20 pounds of back-up batteries for an array of electronics.

“What if we could grow solar cells on the same heavy substrate we use in the standard high-efficiency, low-cost polycrystalline processes?” asked Matthew Reese, an NREL staff scientist in PV research. Afterwards, researchers could transfer the high-efficiency cadmium telluride (CdTe) or copper indium gallium selenide cells to lighter-weight packaging—trimming the weight of the cells.

When soldiers or supply convoys are forced to move slowly on repeated trips, they can become “targets of choice” for enemy combatants. Because of this, the Energy Department and Department of Defense are looking for ways to ease such heavy burdens, and a team of researchers at the National Renewable Energy Laboratory (NREL) is exploring novel approaches for making renewable power sources lighter.

Photovoltaic (PV) cells are the military’s choice to power remote bases, but the ones it uses are not only large and inflexible, they aren’t very efficient. Last summer, NREL embarked on a $1.5 million, three-year research and development contract with the Office of Naval Research to explore making lightweight solar cells. In this work, the journey has been marked by fundamental science—and creative thinking. Read more 


USDA Seeks Applications for Renewable Energy and Energy Efficiency Loans and Grants


USDA Rural Business-Cooperative Service Administrator Sam Rikkers today encouraged rural small businesses and agricultural producers to apply for loans and grants to support renewable energy and energy efficiency projects.

“These projects create long-term, economic benefits for businesses and rural communities,” Rikkers said. “USDA’s funding helps promote U.S. energy independence and supports the production of home-grown energy sources. I encourage all eligible applicants to take advantage of this opportunity.  These investments can help a small business cut costs, expand operations, hire more workers and provide a better service to the communities in which they operate.”

USDA is accepting Rural Energy for America Program (REAP) applications for: 1) energy audit and renewable energy development assistance grants, and 2) renewable energy system and energy efficiency guaranteed loans and grants.

The application deadline for energy audit and renewable energy development assistance grants is Jan. 31, 2017. Applications for renewable energy system and energy efficiency grants of $20,000 or less are due by Oct. 31, 2016, for the firs11204868_10156122621575223_5264684579691067763_nt funding cycle and March 31, 2017, for the second funding cycle.  Applications for renewable energy system and energy efficiency grants of greater than $20,000 and all combination grants and guaranteed loans are due by March 31, 2017. USDA will set aside 20 percent of the funds for grants of $20,000 or less.

Applications for renewable energy system and energy efficiency grants or for loan/grant combinations that are received after March 31, 2017, will be considered in Fiscal Year 2018, which starts Oct. 1, 2017. Guaranteed loan applications will be reviewed and processed when received, with periodic competitions. For additional information, contact the USDA energy coordinator for your state, or see page 71689 of the October 18 Federal Register.

Eligible applicants for renewable energy system and energy efficiency loans and grants include agricultural producers and rural small businesses, which may include tribal business entities, rural electric cooperatives and public power entities. Renewable energy sources include wind, solar, renewable biomass (including anaerobic digesters), small hydro-electric, ocean, geothermal or hydrogen derived from these renewable resources. Eligible applicants for energy audit and renewable energy development assistance grants include State, tribal or local governments; institutions of higher education; and rural electric cooperatives and public power entities.

Congress created the REAP program in the 2002 Farm Bill and reauthorized it in the 2014 Farm Bill with guaranteed funding of no less than $50 million annually for the duration of the five-year bill.

In 2015, USDA provided a $500,000 REAP grant to support SR Camden LLC’s solar farm in Camden, Ark. The $32 million, 12 megawatt solar array on 100 acres at the Highland Industrial Park has more than 150,000 solar panels. The energy produced from the panels is fed to the adjacent electric utility substation and is enough to power about 2,400 homes for a year.

Nationwide, USDA has helped finance more than 12,000 REAP projects since 2009. When fully operational, these projects will generate or save enough energy to power more than 750,000 homes annually, and replace more than 36 million barrels of oil annually.    READ MORE HERE
