MIT researchers develop flex-fuel hybrid trucks

MIT researchers develop flex-fuel hybrid trucks

April 10, 2019 |

In Massachusetts, heavy-duty trucks, such as the 18-wheelers that transport many of the world’s goods from farm or factory to market, are virtually all powered by diesel engines. They account for a significant portion of worldwide greenhouse gas emissions, but little has been done so far to curb their climate-change-inducing exhaust. Now, researchers at MIT […]

MIT professor says biomass-based power worse than coal for the environment

MIT professor says biomass-based power worse than coal for the environment

January 29, 2018 |

In Massachusetts, a new report from MIT Sloan professor John Sterman supports the growing argument that burning wood pellets for power is worse for the climate than burning coal, because of the short-term effects and the “potentially irreversible impacts that may arise before the long-run benefits are realized.” “Because combustion and processing efficiencies for wood […]

MIT researchers better understand how plants protect themselves from too much energy production

MIT researchers better understand how plants protect themselves from too much energy production

July 19, 2017 |

In Massachusetts, photosynthesis, which allows energy from the sun to be converted into life-sustaining sugars, can also be hazardous to green plants. If they absorb too much sunlight, the extra energy destroys their tissue. To combat this, green plants have developed a defense mechanism known as photoprotection, which allows them to dissipate the extra energy. […]

MIT engineers reprogram yeast to convert sugars to fats more efficiently

MIT engineers reprogram yeast to convert sugars to fats more efficiently

February 14, 2017 |

In Massachusetts, MIT engineers have genetically reprogrammed a strain of yeast so that it converts sugars to fats much more efficiently, an advance that could make possible the renewable production of high-energy fuels such as diesel. The researchers modified the metabolic pathways of yeast that naturally produce large quantities of lipids, to make them about […]

MIT researchers scaling down torrefaction technology so small farmers can use it

January 26, 2017 |

In Massachusetts, researchers at the Massachusetts Institute of Technology are working with torrefaction to help small farmers be able to use the technology to produce fuel. Their project is a reactor that uses torrefaction to densify biomass, making it transportable and increasing its shelf life. Torrefaction technology has been used at the industrial scale for […]

MIT and Cambridge researcher develop technique to further cellulosic ethanol production

August 4, 2016 |

In Massachusetts, researchers at MIT and the Cambridge startup Novogy describe a new technique that gives producer microbes the upper hand against unwanted invaders, eliminating the need for such expensive and potentially harmful sterilization methods. The researchers engineered microbes, such as Escherichia coli, with the ability to extract nitrogen and phosphorous—two vital nutrients needed for […]

MIT researchers develop biodiesel from CO2

MIT researchers develop biodiesel from CO2

May 26, 2016 |

In Massachusetts, new research from the Stephanopoulos group at MIT reports engineered microorganisms that can generate sustainable biofuel from carbon dioxide emissions. Their research was recently published in the Proceedings of the National Academy of Sciences. This conversion process starts with mixtures of carbon dioxide and either carbon monoxide or hydrogen, The gas is bubbled into […]

MIT to use drones for tracking sorghum growth in hopes of boost bioenergy capacity

MIT to use drones for tracking sorghum growth in hopes of boost bioenergy capacity

April 26, 2016 |

In Massachusetts, researchers at MIT will next month undertake a season-long experiment by using three drones—one from the air and two by land—to monitor sorghum production every two weeks in an attempt to pinpoint the exact moment of the plant’s peak as a biofuel feedstock. The hope is that using drones and their on-board sensors […]

MIT researchers make waste gas-to-liquid fuel technology breakthrough

March 7, 2016 |

In China, researchers from MIT looked at gaseous substrates that could be made available at low cost and sufficiently large scale for industrial fuel production using a new bioconversion scheme that effectively converts syngas, generated from gasification of coal, natural gas, or biomass, into lipids that can be used for biodiesel production. The integrated conversion […]
