MIT researchers have developed a new method for potentially increasing solar cell efficiency beyond the theoretical limit, reports Daniel Oberhaus for Wired. “What’s cool here is that this is a fundamentally different approach from traditional photovoltaics,” says Joseph Berry of the National Renewable Energy Laboratory.
Larry Edelman at The Boston Globe reports that Commonwealth Fusion Systems (CFS) has completed its first round of venture financing with a total of $115 million. “CFS is working with the Plasma Science and Fusion Center at MIT to develop what it hopes will be the first commercial system that creates power using nuclear fusion,” writes Edelman.
Jonathan Shieber of TechCrunch reports that Commonwealth Fusion Systems, a startup collaborating with MIT, has raised an additional $50 million toward its efforts to develop a commercial fusion reactor. “Commonwealth Fusion expects to have its smallest possible reactor built by 2025 thanks to the research that MIT has done on proprietary magnet technology that the company uses to confine its nuclear reaction,” writes Shieber.
Prof. Donald Sadoway explains the benefits of battery storage in an Associated Press article about energy storage in Arizona. “Absent battery storage, the whole value proposition of intermittent renewable energy makes no sense at all…People just don’t understand that the battery will do for electricity what refrigeration did to our food supply.”
Researchers from a number of institutions, including MIT, are exploring the feasibility of cold fusion, reports Steven Salzberg for Forbes. The researchers explained that while they were unable to successfully produce cold fusion, their exploration of this topic “is likely to have a substantial impact on future energy technologies.”
National Geographic reporter Michael Greshko writes about a new effort by researchers from a number of institutions, including MIT, to reassess the possibility of cold fusion. Prof. Yet-Ming Chiang explains that he hopes to be able to create a “‘reference experiment’ for other labs to also advance research into lower-energy nuclear physics.”
A new MIT study suggests that “strings of plastic balls dangled in the ocean could harvest enough cobalt for hundreds of thousands of electric car batteries,” reports David Adam for New Scientist. The researchers think the system could “catch enough dissolved cobalt from seawater each year to make a battery for every Tesla Model 3 that has rolled off the production line so far,” says Adam.
Prof. Dennis Whyte, director of MIT’s Plasma Science and Fusion Center, speaks with NBC Mach reporter Dan Falk about the possibilities of fusion power. “Fusion will have one of the smallest possible environmental footprints of any power source,” says Whyte. “It will be sustainable for the foreseeable future of mankind.”
Researchers from MIT and Worcester Polytechnic Institute have developed a new process to produce isobutanol, a biofuel, in a cheaper and more efficient way, reports Jonathan Ng for The Boston Herald.
In an article for Bloomberg News, Noah Smith highlights a study by MIT researchers that examines the factors influencing the decline in solar prices. The researchers found that, “from 1980 to 2001, government-funded research and development was the main factor in bringing down costs, but from 2001 to 2012, the biggest factor was economies of scale,” Smith explains.
In a letter to The Boston Globe, Prof. Michael Golay argues that nuclear energy should be included in the portfolio of options used to mitigate the impacts of climate change. Golay notes that “we face the existential challenge of climate change that likely will demand nearly complete replacement of the existing energy infrastructure within this century.”
Prof. Donald Sadoway speaks with CBC News reporter Paul Hunter about his work developing a rechargeable battery that is big enough to power an entire neighborhood, and uses liquid metals and molten salt. Hunter writes that “Sadoway's invention is radically different from anything else in the market.”
Popular Mechanics reporter David Grossman writes that MIT researchers have developed a conceptual design for storing renewable energy for the grid in tanks of white-hot molten silicon. The researchers estimate that their system, “would cost around half as much as the current cheapest form of renewable energy ready to scale out to an entire grid.”
New York Times reporter Brad Plumer writes that a study by MIT researchers examines what forces contributed to the declining cost of solar panels. “We can cut emissions more quickly if we’re strategic about how we design energy policies and invest in R&D,” explains Prof. Jessika Trancik. “And one way to do that is to learn from past successes and figure out exactly why they happened.”
Writing for Ars Technica, Megan Geuss examines a new MIT study that finds, “government and private R&D spending contributed the most to cost-per-watt declines for solar panels since 1980. This spending spurred the low-level efficiency improvements that were important for the solar industry on a technical level.”
