New research by engineers at MIT and elsewhere could lead to batteries that can pack more power per pound and last longer, based on the long-sought goal of using pure lithium metal as one of the battery’s two electrodes, the anode. The new electrode concept comes from the laboratory of Ju Li, the Battelle […] More
Before Fikile Brushett wanted to be an engineer, he wanted to be a soccer player. Today, however, Brushett is the Cecil and Ida Green Career Development Associate Professor in the Department of Chemical Engineering. Building 66 might not look much like a soccer field, but Brushett says the sport taught him a fundamental lesson that […] More
Costs of solar panels have plummeted over the last several years, leading to rates of solar installations far greater than most analysts had expected. But with most of the potential areas for cost savings already pushed to the extreme, further cost reductions are becoming more challenging to find. Now, researchers at MIT and at the […] More
Much of the conversation around energy sustainability is dominated by clean-energy technologies like wind, solar, and thermal. However, with roughly 80 percent of energy use in the United States coming from fossil fuels, combustion remains the dominant method of energy conversion for power generation, electricity, and transportation. “People think of combustion as a dirty technology, […] More
Five-hundred-year floods. Persistent droughts and heat waves. More devastating wildfires. As these and other planetary perils become more commonplace, they pose serious risks to natural, managed, and built environments around the world. Assessing the magnitude of these risks over multiple decades and identifying strategies to prepare for them at local, regional, and national scales will […] More
While so many faculty and researchers at MIT are developing technologies to reduce carbon emissions and increase energy sustainability, one class puts the power in students’ hands. In 2.S999 (Solving for Carbon Neutrality at MIT), teams of students are tasked with developing a plan to achieve carbon neutrality on MIT’s campus by 2060. “It’s a […] More
To avoid the most destructive consequences of climate change, the world’s electric energy systems must stop producing carbon by 2050. It seems like an overwhelming technological, political, and economic challenge — but not to Nestor Sepulveda. “My work has shown me that we do have the means to tackle the problem, and we can start now,” he […] More
When it comes to fulfilling ambitious energy and climate commitments, few nations successfully walk their talk. A case in point is the Paris Agreement initiated four years ago. Nearly 200 signatory nations submitted voluntary pledges to cut their contribution to the world’s greenhouse gas emissions by 2030, but many are not on track to fulfill […] More
