Wind

MIT scientists have discovered a new method to maximize wind farm output, reports Gwen Egan for Boston.com. “While there are pros and cons to this strategy, it’s possible that it could allow for smaller wind farms that take up less land to produce more energy,” says Prof. Michael Howland. “It’s critically important we do this now, as we embark on building much more offshore wind. We need to ensure that our future wind farms maximize efficiency to increase the pace of decarbonization.”

MIT scientists have found that changing the angle of turbine blades on wind farms could increase energy output, reports David Abel for The Boston Globe. “Given the scale of wind deployment needed to achieve state and federal climate goals, we need optimal wind farm performance to ensure efficient, rapid decarbonization,” says Prof. Michael Howland. “Our method resulted in significant energy gains over standard industry operations, and, importantly, it can be instituted with minimal cost.”

The new Wright Brothers Wind Tunnel at MIT, which is capable of reaching wind speeds of up to 230 miles per hour, provides a controlled environment to measure the aerodynamics of an object, reports Matt Shearer for WBZ. "Everybody turns into a little kid when they get into a wind tunnel," says Prof. Mark Drela.

WBUR reporter Bruce Gellerman spotlights a new report by MIT Energy Initiative (MITEI) researchers that emphasizes the importance of developing and deploying new ways to store renewable energy in order to transition to clean energy. “There are a variety of technologies and if we can develop [them] and drive those costs down, it could make getting to net-zero or zero in the electricity sector more affordable,” says Prof. Robert Armstrong, MITEI director.

A new report by researchers from MIT’s Energy Initiative (MITEI) underscores the feasibility of using energy storage systems to almost completely eliminate the need for fossil fuels to operate regional power grids, reports David Abel for The Boston Globe. “Our study finds that energy storage can help [renewable energy]-dominated electricity systems balance electricity supply and demand while maintaining reliability in a cost-effective manner,” says Prof. Robert Armstrong, director of MITEI.

MIT researchers have analyzed the role of long-duration energy storage technologies and found that large storage systems have the potential to lower electricity prices in a carbon-free grid by up to 40%, writes Eric Roston for Bloomberg. 

A new study by MIT researchers finds that St. Elmo’s Fire could help protect airplanes from lightning strikes, reports Caroline Delbert for Popular Mechanics. The researchers found that “the special kind of electrical charge can be used to place a protective and preemptive charge around airplanes in flight, and wind affects flying versus grounded vehicles in opposite ways.”

Axios reporter Ben Geman writes that MIT researchers have found the most effective way to reduce emissions from electricity sources is to use a mix of renewable and other low-carbon tech options. “It’s not about specific technologies. It’s about those key roles that we need filled on the low-carbon team,” explains study co-author Jesse Jenkins.

Kate Baggaley of NBC News highlights a team of MIT researchers who have developed a computer model to explain how albatrosses fly so efficiently. “Unlike other birds that flap their wings frequently, the albatross rides the wind,” which researchers are hoping to duplicate as they attempt to create drones that fly by harnessing power from the wind and sun, she explains.

HuffPost reporter Thomas Tamblyn writes that MIT researchers have developed a new “air-breathing” battery that can store electricity for months. The new battery could harvest, “the vast wind energy waiting to be captured in the North Atlantic, store it for months on end and then release it into the grid for a fraction of the cost that we’re currently paying.”

Umair Irfan of ClimateWire writes that a new paper by Prof. Jessika Trancik finds that renewable energy storage can be a good investment, and provides insight on which storage technologies are the most economically feasible. “One of the major technology challenges of scaling up renewables is developing economically feasible energy storage," says Jessika Trancik.

A study by MIT researchers finds that by adjusting grid operations, China could increase its usage of wind power, reports Chelsea Harvey for The Washington Post. Prof. Valerie Karplus explains that the study “considers the operation of the electric grid and how wind interacts with other sources of generation, particularly coal generation.” 

Boston Globe reporter Stefanie Friedhoff writes about Dick Perdichizzi’s work at the Wright Brothers Wind Tunnel. “Students, companies, and researchers from all over New England come to Perdichizzi to test the effect that moving air has on bicycles, boats, and tall buildings — just about anything curious minds want to expose to the forces of wind,” Friedhoff explains. 

According to The Economist, a battery design “being developed by Donald Sadoway of the Massachusetts Institute of Technology would use two sorts of liquid metal, separated by a liquid electrolyte.” Using metals of varying densities, Sadoway’s design would allow the substances to float as separate layers in a container.

Forbes reporter Bill Tucker writes about battery innovation, highlighting a liquid battery system developed by MIT researchers. The proposed system would operate at dramatically lower temperatures and would allow renewable energy sources to compete with conventional power plants, reports Tucker.
