Prof. Asegun Henry has been named a 2024 Grist honoree for his work developing a “sun in a box,” new and cost-effective system for storing renewable energy, reports Grist. Based on his research, Prof. Henry has founded Fourth Power, a startup working to build a prototype system that will hopefully “allow us to decarbonize electricity,” says Henry.
A Nature editorial discusses the live music industry’s increasing commitment to sustainability, going beyond actions such as bottle recycling to addressing band travel, equipment shipping and set construction. Researchers from MIT’s Environmental Solutions Initiative have “undertaken a project co-funded by the Warner Music Group, Live Nation and Coldplay to analyze the carbon footprint of the live music industry, initially in the United Kingdom and United States, and suggest practical mitigating measures.”
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.
Found Energy, co-founded by Peter Godart '15, SM '19, PHD '21, has developed a method for transforming aluminum scrap metal into energy, reports Hiawatha Bray for The Boston Globe. “The Found Energy system could replace fossil fuel with aluminum-generated hydrogen, a gas that burns at up to 4,000 degrees Fahrenheit, but produces no waste carbon,” writes Bray.
Plonts, a plant-based cheese company co-founded by Nathaniel Chu PhD '19, uses microbes to develop “nutritious, inexpensive and sustainable” cheese alternatives, reports Christine Hall for TechCrunch. Chu says “microbes, whether mold, bacteria or yeast, are important to create that flavor. The microbes themselves are tiny sacs of hundreds of different enzymes with many different combinations,” writes Hall.
Amrita Saigal '10 is the founder and CEO of Kudos, a company that has developed a “sustainable diaper that uses some plastic but is 100% lined with cotton and incorporates other degradable materials like sugarcane and trees,” reports Gabrielle Fonrouge for CNBC. “I care so much about being premium, but accessible,” says Saigal. “That is exactly what I want to do, so that we are accessible to as many people, and cleaner materials are not out of reach.”
New York Times reporter David Gelles spotlights David Keith PhD '91 who “believes that by “intentionally releasing sulfur dioxide into the stratosphere, it would be possible to lower temperatures worldwide, blunting global warming.” “There’s plenty of uncertainty about climate responses,” says Keith. “But it’s pretty hard to imagine if you do a limited amount of hemispherically balanced solar geo that you don’t reduce temperatures everywhere.”
Research Scientist Christopher Mejia-Argueta is interviewed by Marina Mayer of Food Logistics about the food industry’s efforts to achieve a circular supply chain, which could help companies improve their sustainability. “Despite a growing trend to improve the food supply chains from farm to fork and back to farm, scalability is the biggest challenge,” he says.
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.”
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.”
In an interview with The New York Times, Prof. Susan Solomon speaks about her latest book “Solvable: How We Healed the Earth, and How We Can Do it Again,” which offers learnings from past environmental fights to affect future change. “People need to have some hope. We imagine that we never solve anything…but it’s really important to go back and look at how much we succeeded in the past and what are the common threads of those successes,” Solomon says.
Prof. Martin Bazant speaks with Wired reporter Emily Mullin about the importance of proper battery disposal to reduce waste and ensure the materials can be reused. “What we don’t want is to be losing critical minerals from the supply chain,” explains Bazant. “We have to be able to recycle them.”
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 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.
Researchers from MIT and other universities, businesses and government agencies are working to help the state of Massachusetts become a leading producer of climate technology innovations, reports Jeff Young for Newsweek. “Some MIT grads launched a climate tech incubator in Cambridge called Greentown Labs in 2011 and it now hosts hundreds of startups,” explains Young. “The area's venture capital and finance communities are attuned to the climate sector and are investing in companies tackling some of the biggest climate challenges.”
