Fossil fuels

MIT researchers have developed a new membrane that can separate different kinds of fuel by molecular size, which could replace the current energy-intensive crude oil distillation process. “Roughly 1 percent of global energy use goes into separating crude oil into gasoline, diesel, and heating oil,” writes Aamir Khollam for Interesting Engineering. This new membrane “excelled in lab tests…[and] effectively separated real industrial oil samples containing naphtha, kerosene, and diesel.”

New Yorker reporter Brent Crane spotlights Quaise Energy, an MIT geothermal energy startup founded by Carlos Araque BS '01, MS '02. Crane explains that central to Quaise’s system is the gyrotron, a tubular device that “works like a very, very powerful microwave, emitting ‘millimeter waves’ that would vaporize your vegetables; they can generate temperatures of a hundred million degrees Celsius.” Crane notes that: “About a decade ago, Paul Woskov, an MIT research engineer, showed that the technology could be used for ‘energy drilling’ without a physical bit. Quaise’s scientists propose that the heat of a gyrotron could stabilize tunnel walls by vitrifying them into glass.” 

Anurag Bajpayee MS '08, PhD '12 and Prakash Govindan PhD '12 founded Gradiant, an MIT startup “trying to reduce both costs and energy while eliminating chemicals” in water, reports Diana Olick for CNBC. “We take highly contaminated wastewater which contains solvents, which contains dissolved salt, which contains organics, and we eliminate the entire liquid waste,” says Govindan.

Prof. John Sterman speaks with Guardian reporters Oliver Milman and Nina Lakhani about the expansion of fossil fuel developments in wealthy countries despite climate commitments. “The developed countries don’t show any significant efforts to limit drilling, but it’s not just them. Guyana and countries in south-east Asia are also aggressively seeking to expand exploitation activity. This is about national policy but it’s also being driven by the oil companies,” says Sterman. “We can’t keep going on this like.”

Prof. Desirée Plata and her research team have designed “a kind of clay that mimics the behavior of underwater microorganisms to break down methane into water and carbon dioxide,” reports Ivy Scott for The Boston Globe. “The estimates are that you could save a half a degree of warming by 2100 if you cut human-made methane emissions in half, so that’s a pretty big deal,” says Plata. “It’s the only greenhouse gas that can do that. It’s just a question of whether or not we’ll start to see people doing that ... [regionally] and in Massachusetts.”

Writing for The Hill, Prof. Christopher Knittel and graduate student Kailin Graham emphasize the importance of ensuring the transition away from fossil fuels is an equitable process that provides support for vulnerable workers. “If we’re serious about achieving a truly just transition, far more federal policy action is needed,” they write.

A study by MIT researchers has uncovered an, “intricate relationship between jobs and the nation’s energy transition,” reports Kaleigh Harrison for Environment + Energy Leader. The study, “presents an unprecedented county-level examination of the U.S., identifying regions most intertwined with fossil fuels – ranging from intensive drilling and mining operations to heavy manufacturing sectors,” writes Harrison. “The findings underscore not only the expected impact on traditional energy bastions but also highlight the broader, often overlooked, implications for areas heavily invested in manufacturing.”

Fast Company reporter Kristin Toussaint spotlights how MIT researchers have developed a new map detailing how the shift to clean energy could impact jobs around the country. The researchers found that workers could be most impacted in areas that drill for oil and gas, as well as “regions with a high concentration of manufacturing, agriculture, and construction—all industries that rely heavily on coal, oil, and gas.” 

Quaise Energy co-founder Carlos Araque BS '01 MS '02 speaks with PBS Energy Switch host Scott Tinker about the future of geothermal energy. [Geothermal is “truly everywhere so it’s not a resource uncertainty, like there is with oil and gas, there’s always heat, but the technological gap prevents us from getting to it,” says Araque. These gaps “are the one caveat in unlocking this resource for everybody.”

Financial Times reporter Simon Mundy and Kaori Yoshida spotlight Gradiant, an MIT startup that has developed new methods of handling industrial wastewater. “Gradiant promises customers that its technology will allow them to purify and reuse larger amounts of water, reducing the amount they need to source externally,” write Mundy and Yoshia.

Boston Globe reporter Aaron Pressman highlights Gradiant, an MIT startup that has developed a water purification system based on natural evaporation and rainfall cycles to clean wastewater at factories and manufacturing facilities.

Gradiant, an MIT startup, is using water technology to “help companies reduce water usage and clean up wastewater for reuse,” reports Simon Jessop for Reuters.

Quaise Energy, an MIT spinout, is developing a millimeter wave drill to “vaporize enough rock to create the world’s deepest holes and harvest geothermal energy at scale to satisfy human energy consumption without the need for fossil fuels,” reports Tim Newcomb for Popular Mechanics.

MIT startup Quaise Energy is developing an energy-based drill to make geothermal power more accessible, reports Catherine Clifford for CNBC. “The solution to drilling is to replace the mechanical grinding process with a pure energy-matter interaction,” says research scientist Paul Woskov. “Sufficient energy intensity will always melt-vaporize rock without need for physical tools.”

MIT spinoff Quaise Energy is transforming a millimeter-wave drilling technique from nuclear fusion experiments to tap geothermal energy, reports Mark Bergen for Bloomberg. “The company’s drill – it is building three prototypes in laboratories – is about 100 feet tall and looks like convential equipment used in the oil and gas industry,” writes Bergen. “Except built into the center of the drill is a gyrotron, an electrical vacuum designed to heat plasma in thermonuclear fusion machines.
