Tim Kneafsey, a staff scientist at Berkeley Lab’s Earth & Environmental Sciences Area, will lead a new $9 million project aimed at removing technical barriers to commercialization of enhanced geothermal systems (EGS), a clean energy technology with the potential to power 100 million American homes.

Berkeley Lab, a Department of Energy (DOE) National Laboratory, will partner with seven other DOE national labs and six universities to develop field experiments focused on understanding and modeling rock fractures, an essential element of geothermal systems. Scientists will use the Sanford Underground Research Facility (SURF) in South Dakota to create small-scale fracture networks in crystalline rock 1,500 meters below ground.

“We will be putting instrumentation within tens of meters of the fractures and will be able to detect fracturing at a higher resolution than what has ever been done before,” said Kneafsey. “The goal is to work towards increasing our understanding of fracturing and fluid flow in EGS, which could provide a significant amount of electricity as a large quantity of accessible hot rock lies untapped across the U.S.”

EESA Develops New Approach to Restock California’s Groundwater via Almond Orchards, Vineyards

August 3, 2017

Groundwater—the water stored underneath the Earth’s surface between the cracks and spaces in soil, sand, and bedrock—is essential for the California residents and farmers who rely on it for up to 46 percent of their annual water use. Yet during the 2012-2017 drought, the state’s surface water supply was not sufficient to meet demand, resulting in excess groundwater pumping that caused land subsidence of up to 13 inches in some parts of the San Joaquin Valley.

Now a team of scientists at Berkeley Lab’s Earth & Environmental Sciences Area are working with farmers and partners like the Almond Board of California and UC Davis to test on-farm banking, a new approach that has the potential to manage groundwater more sustainably. It’s an improvement on the age-old method of groundwater recharge, the process of replenishing aquifers by infiltrating water from the surface into shallow aquifers.

“On-farm banking has the promise of making the most productive use of the greatest amount of land possible while increasing the reliability and resiliency of California’s groundwater supply,” says EESA scientist Peter Nico, a soil and environmental biogeochemist.

EESA Scientist Builds Cross-Border Collaborations for Geothermal Research

August 1, 2017

Thirty-five years ago, Berkeley Lab’s Earth & Environmental Sciences Area (EESA) scientist Patrick Dobson began his career as a graduate student by conducting field mapping, collecting fluid samples, and learning the ropes from local scientists at the Los Azufres geothermal field in Michoacán, Mexico. During his summer doing field work in Mexico, he met Berkeley Lab’s Marcelo Lippmann, who was attending a symposium on the Cerro Prieto geothermal field, the subject of a collaborative research project between the Lab (funded by the U.S. Department of Energy) and the Comisión Federal de Electricidad (CFE), Mexico’s state-owned utility.

Now—after decades of leading geothermal exploration projects all over the world, including Indonesia, Central America, and South America— Dobson’s work has come full circle.

Earlier this year, he spent two weeks in Ensenada, Baja California, Mexico as a Fulbright Specialist in geothermal research. Hosted by the Center for Scientific Investigation and Higher Education in Ensenada (CICESE), one of the main hubs for geothermal work in the country, Dobson met with Mexican researchers to share knowledge, identify areas of mutual interest, and explore potential areas of collaboration.

Berkeley Lab Scientists Brief California Science Advisory Panel for Food and Agriculture

July 28, 2017

As two-thirds of the fruits and nuts—and over a third of the vegetables—produced in the United States are grown in California, it’s crucial that the Golden State cultivate healthy soils that are resilient to stresses such as climate change, drought, and groundwater overuse. Now scientists at Berkeley Lab’s Earth & Environmental Sciences Area (EESA) and Biosciences Area are contributing to the effort by sharing their expertise with the California Department of Food and Agriculture (CDFA)’s Science Advisory Panel, a group comprised of farmers, agriculture professionals, and experts in areas such as water, conservation, and resource management. Last week, EESA scientist Peter Nico hosted the panel at the Lab to brief them on research related to developing healthy soils, sustainable groundwater management strategies, and climate-adaptive agriculture.
