MIT researchers have “examined how improvements to existing transmission infrastructure could increase electricity delivery without relying entirely on expensive and time-consuming construction of new lines,” reports The Daily Tribune’s Carl Magadia. The researchers “examined three technologies: dynamic line ratings, which adjust power-line capacity based on real-time weather; advanced power flow controls, which redirect electricity away from congested lines; and topology optimization, which improves electricity distribution by reconfiguring grid connections,” notes Magadia.  

Prof. Christopher Knittel joins the Climate One podcast to discuss energy policy and his research on the costs associated with homeowners implementing rooftop solar. “Rooftop solar is raising people's rates,” says Knittel. We should continue to “subsidize rooftop solar in a way that's not regressive, that is not leaning harder on those homes that cannot install solar.” Thinking about: “what is the best, most efficient, and [the] fairest way to make that [equity] happen.”  

Principal Research Scientist Deepjyoti Deka speaks to MassLive’s Tréa Lavery about the type of information stored by data centers. “Anything, mostly, that you are using the computer for, that you are getting some information from, is housed in a data center,” says Deka. “A lot of it is active data handling, but some of it is also data storage.” 

Forbes reporter Marshall Shepherd highlights the Probabilistic Bias Correction tool, a new AI system developed by MIT researchers that could extend weather forecasting predictability beyond two weeks.  

Principal Research Scientist Deepjyoti Deka speaks to MassLive’s Tréa Lavery about the possibility of large data centers being located in greater Boston. “Anything, mostly, that you are using the computer for, that you are getting some information from, is housed in a data center,” says Deka. “When you talk about data centers in greater Boston, I doubt if we have any hyperscale, because there would need to be a gigantic factory that you could observe from a distance. But there are small ones.” 

Fast Company’s Adele Peters highlights Firma Power, a clean energy developer co-founded by MIT alumni aimed at working with data centers to use clean alternatives to gas power. “We started the company with the hypothesis that despite the fact that 98% of what’s in the queue is wind, solar and storage, that’s not getting tapped as the default path to power for large loads—so there’s got to be some market frictions and barriers there,” says Jesse Jenkins SM ’14, PhD ’18.  

MIT researchers have developed the Probabilistic Bias Correction (PBC) tool, which “uses machine learning to identify systematic bias in a model and make corrections” to improve weather forecasts, reports The Verge’s Justine Calma. “The researchers found that PBC improved the accuracy of a leading physics-based weather model by the European Centre for Medium-Range Weather Forecasts (ECMWF) for 98 percent of precipitation and 92 percent of temperature targets,” notes Calma. “The machine learning framework also doubled the accuracy of ECMWF’s new AI forecasting system in the study’s analysis.” 

Gizmodo’s Ellyn Lapointe spotlights the Probabilistic Bias Correction (PBC) tool developed by MIT researchers to “correct systemic errors in forecast models and improve the accuracy of their subseasonal outlooks.” “Extreme weather has the largest impact on our society and improved forecasts of these events can yield large societal benefits,” says Research Scientist Judah Cohen. “Interestingly, previous bias correction schemes actually made forecasts of extreme weather worse, and our model showed clear improvement of extreme weather forecasts.”  

MIT researchers have developed an AI system “that not only minimizes forecasting errors, but learns from its inevitable mistakes through a method called postprocessing,” writes reporter Andrew Paul for Popular Science. “Their AI postprocessing integration blew the existing forecasting models out of the water,” notes Paul. “Such massive improvements could soon help the farmers and energy providers who already rely on subseasonal forecasts, but the benefits may even save lives.” 

MIT startup LNK Energies has created a system to efficiently convert heavy-duty trucks from diesel to hydrogen, “slashing pollution and costs while shielding operators from the price spikes that result from geopolitical instability,” writes Tim De Chant for TechCrunch. “A lot of the reactors that LOHC (Liquid organic hydrogen carriers) companies have today are really large. They’re about the size of a shipping container,” says Alexis Huynh ‘24, cofounder of LNK. “We have shrunk that basically to the size of a mini fridge.” 

MIT spinout Cambridge Heavy Industries is developing a desktop-sized fusion reactor that can enable 50 to 80 experiments per day, writes TechCrunch’s Tim De Chant. “Cambridge Heavy’s fusion reactor uses lasers to compress a fuel target, similar to the groundbreaking experiment that proved controlled fusion reactions could produce more power than they consume,” notes De Chant. “But unlike other inertial confinement designs, Cambridge Heavy’s minimizes the number of lasers required to spark fusion.”  

Boston Globe reporter Jon Chesto spotlights the fall fair event held as part of the MIT x GE Vernova Energy & Climate Alliance, during which, GE Vernova CEO Scott Strazik shared his enthusiasm for hiring MIT graduates. “Something we talk a lot about inside Vernova is the world is changing very quickly but we need to change quicker and even faster than that so we can lead in the world,” says Strazik. “Over the last year-plus on this campus, we see a lot of opportunities for us to get better through bringing you into the organization.”  

In an opinion piece for The Washington Post, Senior Fellow Brian Deese and his colleague Anna Pasnau outline a potential framework for maintaining battery energy storage systems efficiently. Batteries “can reduce the need to run the expensive natural gas ‘peaker’ plants that are used only when demand is high,” Deese and Pasnau write. “And batteries can be deployed quickly—often in months, compared with the years it can take to build new stand-alone electricity generation—meaning they can meet surges in demand.”  

MIT startup Alsym Energy, cofounded by Prof. Kripa Varanasi, has developed an alternative to lithium-ion batteries using sodium ions, writes Morgan Clendaniel for Fast Company. “The battery is nonflammable and nontoxic, allowing it to be placed in more sensitive areas and saving money on cooling systems that often have to be co-installed with large lithium batteries,” explains Clendaniel.  

Prof. Dennis Whyte joins Hakeem Oluseyi, host of GBH’s “Particles of Thought,” to “explore fusion's wildest applications” in space. “There are private companies now looking at ways to exploit fusion for space travel,” says Whyte. “There are also, simultaneously, companies which are looking at using the technology of fusion—particularly the plasma and magnetic technology, which were primarily developed from fusion to get significant improvements in propulsion technology as well.”
