MIT team devises technique to observe hydrogen’s penetration in metal surfaces; understanding embrittlement

Green Car Congress

Researchers at MIT have created a new technique that allows the observation of a metal surface during hydrogen penetration—the process that results in embrittlement of the metal. Using the setup, a clean, fine-polished surface of micrometer-to-millimeter scale can be observed and tested during hydrogen charging.

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

Algorithm Uses Evolution To Design Robots

Cars That Think

To help solve this problem, Jagdeep Bhatia , an undergraduate researcher at MIT and other researchers created a 2D co-design soft robotics simulation system called Evolution Gym. The results are robots that are patchworks of colored squares, moving through video game-like environments. Diversity is the key,” he said. “If

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. To that end, they have integrated their analysis into SESAME, a lifecycle and techno-economic assessment tool for a range of energy systems that was developed by MIT researchers.
