Foam could offer greener option for petroleum drillers

Publish Date: 
Thursday, August 9, 2018 - 11:00am

Princeton researchers have experimentally tested the fracturing behavior of foam for use in hydraulic fracturing, which would use about 90 percent less water than fracking fluids, but the mechanism for foam-driven fracture is not well understood. The research was supported by PEI's Mary and Randall Hack ’69 Graduate Fund and Carbon Mitigation Initiative and led by PEI associated faculty Howard Stone, the Donald R. Dixon '69 and Elizabeth W. Dixon Professor of Mechanical and Aerospace Engineering.

Bourg receives NSF CAREER grant to study fine-grain soil hydrology, mechanics

Tuesday, March 13, 2018 - 10:00am

Ian Bourg, assistant professor of civil and environmental engineering and the Princeton Environmental Institute, has received a five-year CAREER award from the National Science Foundation to study the hydrology and mechanics of fine-grained soils and sedimentary rocks.

By 2100, arid cities will suffer from more severe heat waves than temperate cities

Publish Date: 
Thursday, February 15, 2018 - 11:00am

In a reversal of current conditions, by 2100, arid cities such as Phoenix will become more susceptible to heatwaves compared to their surrounding rural areas, while cities on the eastern seaboard will actually be less severely affected by heatwaves compared to theirs. Co-lead authors were Lei Zhao, a postdoctoral research scholar associated with PEI's Carbon Mitigation Initiative, which supported this research, and Michael Oppenheimer, the Albert G. Milbank Professor of Geosciences and International Affairs and the Princeton Environmental Institute.

Princeton researchers visit Texas wind farm for a first-hand look at growing energy sector

Publish Date: 
Tuesday, May 30, 2017 - 9:15am

Princeton University researchers visited the BP-owned Sherbino Mesa II Wind Farm in Texas on May 3 to understand the technical and financial aspects of wind power and to search for research projects that would be valuable to the industry. Support for the trip was provided by the Princeton Environmental Institute and the Andlinger Center for Energy and the Environment.

Princeton-CMI Annual Meeting Focuses on Climate Research, Innovation, and Policy

Publish Date: 
Wednesday, April 26, 2017 - 4:00pm

Climate science, technology, and policy were the focus of the 16th annual meeting of the Carbon Mitigation Initiative (CMI) held at Princeton University on April 4-5, 2017. Over 100 people gathered to hear presentations and take part in discussions about terrestrial and ocean carbon sinks, modeling of tropical cyclones, energy innovations and disruptive technologies, U.S. climate policy including the regulatory and tax outlook, and climate change perspectives in the era of the Trump administration.

Shared Traits of Abandoned Gas, Oil Wells Could Aid Cheaper, More Effective Cleanup

Publish Date: 
Thursday, November 17, 2016 - 9:15am

Across the United States, abandoned oil and gas wells are a significant source of greenhouse gases, particularly methane. Yet there are so many scattered across the country that stopping the leaks — and even determining which wells are leaking — presents an enormous challenge.

CMI Holds 15th Annual Meeting

Publish Date: 
Wednesday, April 20, 2016 - 9:45am

The 15th annual meeting of the Carbon Mitigation Initiative (CMI) was held on April 13-14, 2016 in London. This is the first time in the 15-year history of CMI that the annual meeting has been held somewhere other than the Princeton University campus.

Ocean Fertilization Could Be a Zero-Sum Game

Publish Date: 
Monday, February 1, 2016 - 4:30pm

Scientists plumbing the depths of the central equatorial Pacific Ocean have found ancient sediments suggesting that one proposed way to mitigate climate warming--fertilizing the oceans with iron to produce more carbon-eating algae--may not necessarily work as envisioned. 

In Rainforests, Battle for Sunlight Shapes Forest Structure

Publish Date: 
Friday, January 8, 2016 - 4:30pm

Despite their diversity, the structure of most tropical rainforests is highly predictable. Scientists have described the various sizes of the trees by a simple mathematical relationship called a power law.
