governor patrick joins ambri for opening of manufacturing facility
Massachusetts Governor Deval Patrick joined other state and federal officials in a ceremonial ribbon cutting for Ambri, an innovative electricity storage start-up company, which opened its first battery manufacturing facility today. At the plant, located in Marlborough, Massachusetts, Ambri will demonstrate the next-generation equipment and processes that will provide the foundation for global manufacturing of its low-cost electricity storage systems.
Emissionless metal making method could curb a major source of greenhouse gases.
The idea for the new method, which was reduced to practice by materials chemistry professor Donald Sadoway and assistant professor of metallurgy Antoine Allanore, and post-doc Lan Yin, arose when Sadoway broadened his earlier work on an inert anode for aluminum electrolysis. By extending the chemistry of the solvent electrolyte to molten oxide he recognized that the selection criteria would specify the comparatively cheap iron-chromium alloy as an oxygen-evolving anode while liquid iron is being produced at the cathode.

Sadoway and colleague, Antoine Allanore find a way to make pure, cheap steel without any greenhouse-gas emissions.
Molten oxide electrolysis (MOE) is an electrometallurgical technique that enables the direct production of metal in the liquid state from oxide feedstock, and compared with traditional methods of extractive metallurgy offers both a substantial simplification of the process and a significant reduction in energy consumption.
MIT Homepage: One order of steel, hold the greenhouse gases
Steelmaking, a major emitter of climate-altering gases, could be transformed by a new process developed at MIT.
Anyone who has seen pictures of the giant, red-hot cauldrons in which steel is made — fed by vast amounts of carbon, and belching flame and smoke — would not be surprised to learn that steelmaking is one of the world’s leading industrial sources of greenhouse gases. But remarkably, a new process developed by MIT researchers could change all that.
