Emissions

Prof. Jacopo Buongiorno speaks with Danny Lewis, host of The Wall Street Journal’s “Future of Everything” podcast, about the future of nuclear power plants. “As countries, regions, businesses contemplate their future plans for reducing carbon emissions, nuclear is one technology that they have got to consider,” says Buongiorno. “It's an incredibly dense energy source, so you don't need a big supply chain that continuously feeds the power plant with fuel, the same way that you would with coal, for example. Also, the machine itself, the reactor is very, very compact.”

Prof. Jessika Trancik speaks with Bloomberg reporter Kyle Stock about the importance of scrappage programs, especially those that incentivize electrifying the current fleet of vehicles in the United States. “At any given point in time, you care about the composition of the fleet,” says Trancik. “Funding programs that would help turn over the fleet more rapidly makes a lot of sense.”

Principal Research Scientist Emre Gençer speaks with The Independent reporter Louise Boyle about natural hydrogen and its potential as a future renewable energy source. “There is a ‘mismatch’ where natural hydrogen is being discovered and where it could be used, which would require massive investments in completely new infrastructure,” says Gençer. “I think it will be part of the solution but we need to take it with a grain of salt.”

MIT researchers have developed a supercapacitor comprised of concrete and charcoal, that can store electricity and discharge as needed, reports Aleks Phillips for Newsweek. Researchers hope the device can provide “a cheap and architectural way of saving renewable energy from going to waste,” writes Phillips.

Postdoctoral associate Milan Klöwer shares how large conferences can impact air travel and personal carbon footprints, reports Sydney Johnson for KQED. “Flying is one of the sectors where there are enormous inequalities,” says Klöwer. “The people that earn the most [money] fly the most, and therefore have personal carbon footprints that are thousands of times larger than the poorest people on the planet. There is a responsibility for people to understand that problem about how they are personally emitting.”

Researchers at MIT have developed a conceptual design for a system that can efficiently produce “solar thermochemical hydrogen,” reports Xinhua. “The system harnesses the Sun's heat to directly split water and generate hydrogen -- a clean fuel that can power long-distance trucks, ships, and planes, while in the process emitting no greenhouse gas emissions.”

WBUR reporter Daniel Ackerman spotlights Sublime Systems, an MIT startup working to develop “construction-ready, emissions-free cement.” Ackerman explains that: “Sublime’s new approach uses electricity instead of heat. That means the process can be powered with renewable energy rather than fossil fuels. The method also prevents carbon dioxide from escaping the carbon-rich limestone during combustion.”

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.”

Boston Globe reporter Macie Parker spotlights the new John A. Volpe National Transportation Systems Center in Kendall Square, the first building to open in MIT’s redevelopment of the 14-acre Volpe site that will ultimately include “research labs, retail, affordable housing, and open space, with the goal of not only encouraging innovation, but also enhancing the surrounding community.” Parker highlights the green technology included in the new Volpe Center: solar panels; triple-paned glass; electric vehicle charging stations; a rainwater reclamation and reuse system; and green and cool roof technology to lower energy use. 

MIT researchers have devised a new carbon capture system that “relies on the reaction between CO2 in flue gas and a fine mist of electrically charged particles,” reports Karmela Padavic-Callaghan for New Scientist. The researchers believe their design could be “95 per cent efficient at capturing carbon dioxide, while measuring less than 4 meters long,” Padavic-Callaghan notes. “Their analysis also showed that the approach would reduce capital costs of adding carbon capture to power plants by about 2.6 times compared with current technology.”

MIT Energy Initiative Interim Director Robert Stoner speaks with Boston Public Radio hosts Jared Bowen and Andrea Cabral about the MIT Energy Initiative and low – or even no – carbon solutions that could mitigate climate change.

Researchers at MIT have developed a supercapacitor, an energy storage system, using cement, water and carbon, reports Macie Parker for The Boston Globe. “Energy storage is a global problem,” says Prof. Franz-Josef Ulm. “If we want to curb the environmental footprint, we need to get serious and come up with innovative ideas to reach these goals.”

Writing for The Hill, Andre Zollinger, senior policy manager at J-PAL Global, makes the case that “current attention to air pollution can be transformational for how we tackle climate change. Policy leaders in the U.S. and abroad should seize this moment of reckoning over our common struggle for clean air as an opportunity to focus on policies that are known to curb air pollution and simultaneously combat climate change.”

Sean Hunt MS ’13 PhD ’16 co-founded Solugen, a startup working to develop industrial chemicals with environmentally friendly ingredients, reports David H. Freedman for Newsweek. “The company's goals over the next seven years are to reduce the carbon emissions released by industry into the environment by an amount equivalent to eliminating 2 million cars, and to make enough bioplastic to get rid of 5 billion non-degradable plastic bottles,” writes Freedman.

Studies by researchers at MIT have found “that shifting to electric vehicles delivers a 30% to 50% reduction in greenhouse gas emissions over combustion vehicles,” reports Tom Krisher for Associated Press. According to Prof. Jessika Trancik, “electric vehicles are cleaner over their lifetimes, even after taking into account the pollution caused by the mining of metals for batteries,” writes Krisher.
