"Hydrogen is the most abundant element in the universe but is usually found in compound form. It can be extracted from a variety of sources, including water, fossil fuels and biomass but this requires energy and can release carbon dioxide into the atmosphere. Geologic hydrogen — or natural hydrogen — is pure hydrogen, generated through water-rock interactions deep in the Earth’s subsurface without active stimulation, the researchers said."

"The power-storing building material could also help to offset some of the air pollution generated by the cement industry, widely reported as spewing  5-8% of worldwide planet-warming gas pollution. Those harmful, heat-trapping fumes are contributing to a warmup that is impacting even classroom performance, according to the Environmental Protection Agency." 

"The team used a 3M solution of LiPF6 electrolyte dissolved in a 1,3-dioxane and dimethoxyethane solution mixed with a volumetric ratio of 1:3. The unique chemical formulation helps form a solid-electrolyte interphase (SEI) that holds together silicon particles, even when they are fractured during charge-discharge cycles. This aids in maintaining the ionic conduction and keeping unnecessary reactions to a minimum."

"Savor is confident that its technology can be used to make butter and multiple other animal-derived fats, such as milk and cheese. The company also plans to use this approach to make ice cream and edible oils."
