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.

Commonwealth Fusion Systems, MIT’s Plasma Science and Fusion Center and others are working to build SPARC, a prototype device that aims to extract net energy from plasma and generate fusion power, reports Philip Ball for Scientific American. “SPARC will be a midsize tokamak in which the plasma is tightly confined by very intense magnetic fields produced by new high-temperature superconducting magnets developed at MIT and unveiled in 2021.”  

Ubiquitous Energy, an MIT startup, has created a transparent photovoltaic glass coating, called UE Power, that can turn any surface into a tiny solar panel, reports Teodosia Dobriyanova for Mashable. “The company, however, is prioritizing the use of UE Power on windows in an attempt to help buildings reduce their colossal climate footprint,” writes Dobriyanova.

Prof. Christopher Knittel speaks with Radio Boston host Tiziana Dearing about how high electric bills are impacting efforts to address climate change. The current artificial inflation of the volumetric rate “makes electrification hard, it makes it more expensive,” notes Knittel. “As we, as a Commonwealth, want to move toward electrification, it’s a big headwind that is going to push against our climate goals,” says Knittel. 

“The Sun Queen,” a new documentary on PBS, will highlight the life of the late former MIT Prof. Mária Telkes and her work in developing solar energy. Telkes is known for her “work on the 1948 Dover Sun House, a solar-heated model home created by an all-female team,” reports Erin Blakemore for The Washington Post.

In an opinion piece for The Boston Globe, Prof. Christopher R. Knittel explains why electricity bills in Massachusetts can be so high and how to address the issue. “State law requires Massachusetts to cut greenhouse gas emissions relative to 1990 levels by 50 percent by 2030 and by 85 percent by 2050,” writes Knittel. “In short, we need to replace gasoline and natural gas with electricity. But how we price electricity is making this effort to address climate change harder." 

MIT researchers have found that placing EV charging stations in strategic locations and setting up charging systems to initiate charging at delayed times could help reduce the impact of EVs on the electrical grid, reports Michael Schoeck for PV Magazine.

MIT scientists have found that delayed charging and strategic placement of EV charging stations could help reduce additional energy demands caused by more widespread EV adoption, reports Grace Carroll for Fast Company. “Leveraging these two strategies together significantly eliminates any additional energy demands,” writes Carroll, “and can be tailored to specific local conditions to help cities meet their decarbonization goals.”

A new study by MIT researchers finds that strategic placement of EV charging stations and creating systems to help stagger charging times could help reduce or eliminate the need for new power plants to handle the impact of EV charging on the grid, reports Sharon Udasin and Saul Elbein for The Hill. The researchers found that “better availability of charging stations at workplaces could help take advantage of peak power being produced midday by solar energy facilities.”

Carlos Casanovas MS ’14 co-founded X1 Wind, a startup that has developed a floating wind turbine prototype, reports Andrew Paul for Popular Science. “Floating wind is set to play a vital role supporting the future energy transition, global decarbonization and ambitious net-zero targets,” says Casanovas.

Researchers at MIT have predicted that without improvements in hardware efficiency, energy consumption and emissions from autonomous vehicles could be “comparable to that of data centers today,” reports Sarah Wells for Popular Mechanics. “In order to reduce the future carbon footprint of AVs, scientists will need to make the computing systems of AVs, including smart sensors, far more efficient,” writes Wells. 

MIT researchers have developed a new two-step electrochemical process to remove carbon dioxide out of seawater, reports John Fialka for E&E News.  The new approach “cuts energy costs and expensive membranes used to collect CO2 to the point where merchant ships that run on diesel power could collect enough CO2 to offset their emissions,” Fialka writes.  

An MIT study has found that the wide spread adoption of self-driving cars could lead to increased carbon emissions, reports Rima Sabina Aouf for Dezeen. “The study found that with a mass global take up of autonomous vehicles, the powerful onboard computers needed to run them could generate as many greenhouse gas emissions as all the data centers in operation today,” writes Aouf.

A new study by MIT researchers finds that “the energy required to run computers in a future global fleet of autonomous vehicles could produce as much greenhouse gas emissions as all the data centers in the world,” reports Sharon Udasin for The Hill. The researchers found that “1 billion such cars, each driving for an hour daily, would use enough energy to generate the same amount of emissions that data centers do today.”

Politico reporter Derek Robertson writes that a new study by MIT researchers finds the computing power required to replace the world’s auto fleet with AVs would produce about the same amount of greenhouse gas emissions as all the data centers currently operating. Robertson writes that the researchers view the experiment “as an important step in getting auto- and policymakers to pay closer attention to the unexpected ways in which the carbon footprint for new tech can increase.”
