Prof. Admir Masic speaks with New York Times reporter Amos Zeeberg about his research studying the benefits of lime clasts – a material used in ancient Roman infrastructure. According to Masic’s research, “these lime clasts were actually reservoirs of calcium that helped fill in cracks, making the concrete self-healing,” writes Zeeberg. “As cracks formed, water would seep in and dissolve the calcium in the lime, which then formed solid calcium carbonate, essentially creating new rock that filled in the crack.”

Seonghoon Woo PhD '15, Jongwon Choi PhD '17, Young Suk Jo SM '13, PhD '16, and Hyunho Kim SM '14, PhD '18 have co-founded Amogy – a startup company that is using ammonia produced by renewable energy as a carbon-free way to fuel a tugboat, report Jennifer McDermott and Michael Hill for The Associated Press. “Without solving the problem, it’s not going to be possible to make the planet sustainable,” says Woo. “I don’t think this is the problem of the next generation. This is a really big problem for our generation.”

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.

Writing for Foreign Affairs, MIT Innovation Fellow Brian Deese proposes a Clean Energy Marshall Plan to combat climate change and renew U.S. leadership on a global stage, arguing this can be done in a way that promotes U.S. interests and supports aligned countries. “In this moment of domestic economic strength—stark against the backdrop of heightened competition, a fracturing world, and a raging climate crisis—the United States can do something generous for people across the globe in a way that benefits Americans,” writes Deese. “It should take that leap, not just because it is the morally right thing to do but also because it is the strategically necessary thing to do.” 

Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '22  founded AgZen, a company aimed at reducing pesticide use by employing a feedback-optimized spraying system, reports Steven Savage for Forbes. Savage notes that for the researchers behind AgZen, “MIT turned out to be a good place to work on the specific imaging technology and on the AI needed to translate that into a practical solution for farmers.”

Writing for Fast Company, Moshe Tanach highlights how researchers from the MIT Lincoln Laboratory Supercomputing Center are developing new technologies to reduce AI energy costs, such as power-capping hardware and tools that can halt AI training. 

An analysis by The Atlantic’s Ronald Brownstein notes despite Republican resistance to electric vehicles, many new production facilities are located in GOP-represented states. MIT Innovation Fellow Brian Deese explains EV companies are simply seeking space and nearby manufacturing and construction capacity, but said “it’s pretty hard to think of a technology where there was a cheaper, better technology to solve a consumer need and consumers prioritized a cultural or political patina over lower costs and higher quality.”

Prof. Kripa Varanasi and Vishnu Jayaprakash SM '19, PhD '21 co-founded AgZen, an MIT spinoff that is developing new technologies to improve the performance and effectiveness of pesticide treatments, reports The Economist. The new technologies “could reduce the total amount of fungicides and insecticides sprayed over complete crops by some 90%, as well as cutting the amount of adjuvants required,” writes The Economist.

Prof. Jacopo Buongiorno talks with Steve Curwood of Living on Earth about new investments in nuclear power generation, advanced reactors and waste disposal. He notes roughly half the clean energy in the U.S. comes from nuclear, with great potential due to its adaptability. “The nice thing about nuclear is that it’s a fairly versatile energy source,” explains Buongiorno. “It can give you heat, if you want heat. It can give you electricity if you want electricity. It can give you hydrogen if you need hydrogen, or some kind of synthetic fuel for transportation." 

Axios reporter Courtenay Brown spotlights a new report by researchers from MIT and the Brookings Institute that finds poorer counties in the U.S. with lower employment rates have, “attracted a large share of the hundreds of billions of dollars allocated for clean energy projects, semiconductor mega-factories and more.” Brian Deese, an Innovation Fellow at MIT, explains that: “Distressed communities are attracting new clean energy and semiconductor investment at roughly twice the rate of traditional private investment. If this trend continues, it has the potential to change the economic geography of the country and create economic opportunity in parts of this country that too many people have written off in the past.”  

Reuters reporter Timothy Appell spotlights a new study by researchers from MIT and the Brookings Institution that finds, “a surge of factory building fueled by Biden administration investments in ‘strategic sectors’ such as clean energy and semiconductors has so far flowed disproportionately to U.S. counties with relatively distressed economies and notably has not tracked ‘Democratic geography.’”

Researchers at MIT have developed a cathode, the negatively-charged part of an EV lithium-ion battery, using “small organic molecules instead of cobalt,” reports Hannah Northey for Energy Wire. The organic material, "would be used in an EV and cycled thousands of times throughout the car’s lifespan, thereby reducing the carbon footprint and avoiding the need to mine for cobalt,” writes Northey. 

Fast Company reporter Adele Peters spotlights how researchers at MIT have combined cement with carbon black to make concrete that can store energy as one of the climate tech innovations that provide hope “that it’s still possible to avoid the worst impacts of climate change.” With this new technology, “the foundation of your future house could eventually store solar power from your roof,” explains Peters.

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.

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.”
