DOE Awards $92 Million for Groundbreaking Energy Research Projects
DOE announced on July 12 that it awarded $92 million in Recovery Act funds for 43 cutting-edge research projects that aim to dramatically improve how the U.S. uses and produces energy.
DOE's Advanced Research Projects Agency-Energy (ARPA-E) is coordinating the work in 18 states. The research projects are designed to accelerate innovation in green technology while increasing U.S. competitiveness in grid-scale energy storage for renewables, power electronics, and building efficiency.
This round of ARPA-E grants focuses on three areas: Grid-Scale Rampable Intermittent Dispatchable Storage (GRIDS), Agile Delivery of Electrical Power Technology (ADEPT), and Building Energy Efficiency Through Innovative Thermodevices (BEET-IT).
GRIDS projects seek affordable, large-scale energy storage needed to enable widespread use of wind and solar power. This program is searching for revolutionary new storage technologies that exhibit energy, cost, and cycle life that is comparable to that of pumped hydropower but which are modular and can be widely implemented at any location across the power grid.
Ultimately, technologies developed through this program will be scalable to the gigawatt and gigawatt-hour levels of power and energy capacity. On one GRIDS project being funded, General Atomics and the University of California, San Diego will collaborate to develop a novel flow-battery technology that pumps chemicals through a battery cell when electricity is needed. The battery revolutionizes a century-old, lead-acid battery technology to achieve the low cost, high efficiency, and reliability needed for use on the electric grid.
ADEPT is focused on dramatically improving the efficiency and cost of power conversion and switching, which are among the main causes of electrical efficiency loss across the grid and in electrical applications from cars to computers.
ADEPT projects explore integrated circuits that incorporate high-voltage transistors and high-performance magnetic materials. For example, Cree, Inc., a semiconductor manufacturer, is exploring silicon carbide power modules for grid-scale power conversion. The project will develop advanced transistors for electrical substations that can make the grid more flexible. With advanced transistors, electrical substations could replace today's massive distribution transformers with suitcase-sized electronic transformers.
BEET-IT will focus on cutting building energy consumption. Structures now consume 40% of U.S. primary energy, that is, energy embodied in resources prior to undergoing any human-made conversions, and account for 40% of U.S. CO2 emissions. New, more efficient methods of cooling represent a great opportunity to reduce energy consumption and GHG emissions from buildings.
Battelle Memorial Institute will research the absorption-osmosis cooling cycle to develop an air conditioning system that uses water as a refrigerant and salt as the heat absorber. The system uses reverse osmosis to efficiently separate water from the salt solution. The project will receive $400,000 in funding.
These awards complete ARPA-E's grants under its Recovery Act funding, which in three rounds since last year has selected 117 projects for $349 million in funding. See the DOE press release, the project selections (PDF 459 KB), the technical descriptions (PDF 545 KB), and the ARPA-E Web site.
DOE, DOI Pick Solar Demo Site in Nevada Desert
DOE and the U.S. Department of Interior (DOI) announced on July 8 that they will collaborate on a new "solar demonstration zone" to demonstrate cutting-edge concentrating solar power (CSP) technologies.
