Biochemical Conversion of Lignocellulosic Biomass to Ethanol This course describes in detail a potential biochemical ethanol conversion process developed by NREL that converts corn stover to ethanol by dilute-acid pretreatment, enzymatic saccharification, and co-fermentation. The process uses co-current dilute-acid pretreatment of lignocellulosic biomass (corn stover), followed by enzymatic hydrolysis (saccharification) of the remaining cellulose, followed... Learn More

Renewable Energy for Water Desalination The United States has abundant agricultural and forestry resources that could be a significant resource for bioenergy. With research, land resources could be effectively used for feedstock production and still meet demand for production of other goods and services. By 2030, about 1 to 1.6 billion dry tons of sustainably... Learn More

Biofuels Action Plan The United States has abundant agricultural and forestry resources that could be a significant resource for bioenergy. With research, land resources could be effectively used for feedstock production and still meet demand for production of other goods and services. By 2030, about 1 to 1.6 billion dry tons of sustainably available biomass... Learn More

UV Disinfection for Wastewater Treatment This course presents the results of a study that was conducted to determine the long-term benefits and costs associated with three different ultraviolet radiation (UV) disinfection alternatives with respect to chlorination/dechlorination. Chlorination has been the preferred disinfection method used for treating WWTP effluent, but concerns about worker and public safety... Learn More

America’s Greatest Projects and Their Engineers VIII Author: Dominic Perrotta This course describes the seemingly impossible mission of the Apollo Program – “landing a man on the Moon and returning him safely to the Earth” by the end of the 1960s. It focuses on several of the key challenges including the need to design components... Learn More
