Geopolitical risks to U.S. oil supply lowest since the early 1970s
The geopolitical risks to the U.S. oil supply are the lowest since the early 1970s, due to fracking, climate action and a more diverse global supply, according to a new study. America’s energy prosperity contrasts with a more fraught period for energy-exporting countries where geopolitical challenges have been compounded by fiscal stress and rising domestic energy demand, the authors said.

To reduce the number of bigger earthquakes in Oklahoma, inject less saltwater
Starting around 2009, saltwater disposal (SWD) volume began increasing dramatically as unconventional oil and gas production increased rapidly throughout Oklahoma. As a result, the number of magnitude 3-plus earthquakes rattling the state has jumped from about one per year before 2011 to more than 900 in 2015. Oklahoma is now the most seismically active state in the lower 48 United States.

New technique could help coal plants reduce greenhouse gas emissions
Carbon capture could help the nation’s coal plants reduce greenhouse gas emissions, yet economic challenges are part of the reason the technology isn’t widely used today. That could change if power plants could turn captured carbon into a usable product.

Geologists report new findings about Kansas, Oklahoma earthquakes
In the more than three decades between 1977 and 2012, only 15 earthquakes with a magnitude of 3.0 or greater were recorded in the entire state of Kansas. Since 2012 more than 100 earthquakes of 3.0 or greater have been recorded in only two counties in the state, Sumner and Harper. These include the largest earthquake ever monitored in Kansas in November 2014, a magnitude 4.9 event near the Sumner County town of Milan. The frequency of earthquakes has continued to increase. Between May 2015 and July 2017, sensors detected more than 2,400 earthquakes in Sumner County alone, ranging in magnitude from 0.4 to 3.6. As concern rises about earthquakes induced by human activity like oil exploration, geologists report a new understanding about recent earthquakes in Kansas and Oklahoma.

Reusable sponge soaks up oil, revolutionizing oil spill and diesel cleanup
When the Deepwater Horizon drilling pipe blew out seven years ago, beginning the worst oil spill in U.S. history, those in charge of the recovery discovered a new wrinkle: the millions of gallons of oil bubbling from the sea floor weren’t all collecting on the surface where it could be skimmed or burned. Some of it was forming a plume and drifting through the ocean under the surface. Scientists have invented a new foam, called Oleo Sponge, that addresses this problem.

MSU urged to pull the plug on an “eco-terrorism” video game
Michigan State University’s award-winning computer game development lab has developed a new computer game called “Thunderbird Strike.” Dr. Elizabeth LaPensee, the game’s designer, says that, among other things, the game is designed to “bring awareness to pipeline issues and contribute to the discontinuation of [Enbridge’s] Line 5.” Enbridge’s Line 5 is a 645-mile, 30-inch-diameter pipeline that travels through Michigan’s Upper and Lower Peninsulas. In the game, players get to blow up pipelines. Oil industry officials argue that the game, in effect, encourages players to engage in acts of domestic terrorism.

Battelle completes 15-year CO2 storage project at Mountaineer Power Plant
One of the first tests for geologic storage of carbon dioxide at a commercial, coal-fired power plant has concluded, more than fifteen years after it began, completing a journey from an initial exploratory well to successful operations and site closure. The Mountaineer project helped establish the technical viability of carbon capture and storage (CCS) to reduce greenhouse gas emissions from coal-fired power plants, and to store carbon dioxide in geologic layers with limited prior data.

Concerns about safety of rail transport of energy liquids, gases
The U.S. increased production of crude oil, natural gas, and corn-based ethanol created unforeseen demands and safety challenges on their long-distance transportation via pipelines, tank barges, and railroad tank cars. A debate is underway about whether the domestic energy revolution was placing stress on the transportation system that would sacrifice safety.

Climate action window could close as early as 2023
As the Trump administration repeals the U.S. Clean Power Plan, a new study underscores the urgency of reducing greenhouse gas emissions—from both environmental and economic perspectives. For the U.S. most energy-hungry sectors—automotive and electricity—the study identifies timetables for action, after which the researchers say it will be too late to stave off a climate tipping point. And the longer the nation waits, the more expensive it will be to move to cleaner technologies in those sectors—a finding that runs contrary to conventional economic thought because prices of solar, wind and battery technologies are rapidly falling, the study’s authors say.

Why Rick Perry’s proposed subsidies for coal fail Economics 101
In a controversial proposal, Energy Secretary Rick Perry has asked federal regulators to effectively subsidize coal and nuclear power plants at ratepayers’ expense. Subsidizing utilities to burn more coal would worsen coal’s major negative externalities in the name of some dubious positive externalities. Deregulated power markets already have measures in place to support efficient levels of investment in reliability and resilience. There is surely room for refinement, but Perry’s proposal is the opposite of refined. It asks government to interfere in well-functioning markets, which is not something Republicans usually support – especially since it will come at great expense to ratepayers. Subsidizing coal for its reliability attributes is like subsidizing bacon for its nutritional content. There are better ways to get your vitamins, and better ways to keep the lights on.

Filter removes fracking-related contaminants from water
A new filter produced has proven able to remove more than 90 percent of hydrocarbons, bacteria and particulates from contaminated water produced by hydraulic fracturing (fracking) operations at shale oil and gas wells. The process turns a ceramic membrane with microscale pores into a superhydrophilic filter that “essentially eliminates” the common problem of fouling.

Western energy sector target of sophisticated attack by Russian-linked group Dragonfly
The energy sector in Europe and North America is being targeted by a new wave of cyberattacks that could provide attackers with the means to severely disrupt affected operations. The group behind these attacks is known as Dragonfly. The group has been in operation since at least 2011 but has re-emerged over the past two years from a quiet period following exposure by Symantec and a number of other researchers in 2014. This “Dragonfly 2.0” campaign, which appears to have begun in late 2015, shares tactics and tools used in earlier campaigns by the group.

139 countries could be powered by 100 percent wind, water, and solar energy by 2050
The latest roadmap to a 100 percent renewable energy future from twenty-seven experts is the most specific global vision yet, outlining infrastructure changes that 139 countries can make to be entirely powered by wind, water, and sunlight by 2050 after electrification of all energy sectors. Such a transition could mean less worldwide energy consumption due to the efficiency of clean, renewable electricity; a net increase of over twenty-four million long-term jobs; an annual decrease in 4-7 million air pollution deaths per year; stabilization of energy prices; and annual savings of over $20 trillion in health and climate costs.

U.S. advanced nuclear program unlikely to deliver on its mission
Despite repeated promises over the past eighteen years, the U.S. Office of Nuclear Energy (NE) is unlikely to deliver on its mission to develop and demonstrate an advanced nuclear reactor by the mid-twenty-first century. That is the conclusion of a new study which used data obtained through the Freedom of Information Act to reconstruct the program’s budget history.

Wind energy: Technology advancements, improved project performance, low prices
Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the U.S. Department of Energy. Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.
