Electricity sourced from sun and wind is used to split water into hydrogen and oxygen in a process called electrolysis. They are employing a special microbial fermentation process similar to biogas production to produce hydrogen directly from organic waste. KG in the HyPerFerMent I project to produce renewable hydrogen from biomass.

Hydrous ethanol (also sometimes known as azeotropic ethanol) typically ranges from 186 proof (93% ethanol, 7% water) to 192 proof (96% ethanol, 4% water). Earlier post.). It’s a good, fast way to adapt technology into an existing engine by manufacturing a retrofit kit that can be installed on current engines or on newer engines.

A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.

Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.

But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. Wastes from cattle, chickens and other livestock include nitrogen. Nitrogen-based fertilizers help California farmers produce more than 400 agricultural commodities—vegetables, fruits, meats and dairy products—worth $36 billion a year.

HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
