The four highlights of the study noted were: The US national grid updateĪ study from the Massachusetts Institute of Technology, titled “The value of inter-regional coordination and transmission in decarbonizing the US electricity system,” published in Joule, asserts that “streamlining the planning and permitting process for new transmission and coordinating decarbonization at the national (rather than state) level could enable a more efficient and rapid transition to a zero-carbon electricity system.” The high temperatures, copper foil, and gas then transformed the coal powder into polycrystalline graphite.īattery University explains how graphite works in Li-ion batteries here. Specifically, four major factors are identified for successful conversion: (1) high temperature (2) reducing environment (3) catalyst and (4) microwave radiation. The coal powder was put on copper foil and sealed in glass containers with a gas mixture of argon and hydrogen, before being placed in a microwave oven.Ĭhris Masi, lead author of the paper, said:īy cutting the copper foil into a fork shape, sparks were induced by the microwave radiation, generating an extremely high temperature of more than 1,800 degrees Fahrenheit within a few seconds. Previous research has shown that microwaves can be used to reduce the moisture content of coal and remove sulphur and other minerals, but in this latest experiment, the only treatment required was to grind raw Wyoming’s Powder River Basin coal into powder, reports. Scientists have managed to successfully convert raw coal powder into nano-graphite, which is used in lithium-ion batteries, among other things, according to a study, “Converting raw coal powder into polycrystalline nano-graphite by metal-assisted microwave treatment,” published in the journal Nano-Structures & Nano-Objects.
