Raman Instrument Advances Study of Greener Fuels for Aerospace
WASHINGTON, D.C., Sept. 20, 2022 — There is much interest in developing aerospace engines that run on renewable, hydrogen (H2-rich) fuels. In addition to providing sustainability, these fuels exhibit a high specific impulse (i.e., the measure of how efficiently the chemical reaction in the engine creates thrust). A significant amount of research is being conducted in the development of technologies enabling H2-based, carbon-neutral combustion. To boost research into H2 that could lead to more environmentally friendly
