Berkeley Lab releases 8th edition of databook on China’s energy and environment; finding the “missing” energy consumption

Green Car Congress

We have gathered statistical information on energy and energy demand drivers from all different resources, such as the China Environment Yearbook , the Transportation Yearbook , the Power Yearbook , the Iron and Steel Yearbook , the Cement Almanac , statistics of oil companies and power companies. It was underreported. —David Fridley.

Lifecycle Study Finds Algae as Bioenergy Feedstock Has Higher Environmental Impacts than Conventional Crops in Energy Use, GHG Emissions, and Water Use; The Importance of Using Waste Streams

Green Car Congress

Terrestrial bioenergy feedstock crops such as switchgrass, canola and corn have lower environmental lifecycle impacts than algae in energy use, greenhouse gas emissions, and water regardless of cultivation location, according to a new lifecycle assessment by researchers at the University of Virginia. Article ASAP doi: 10.1021/es902838n.

Study of 7 years of production data supports billion-ton biofuels feedstock estimate

Green Car Congress

An article on environmental mapping of biomass resources in the continental United States will also be published in that issue. There’s not one that makes sense everywhere; it’s more of a localized environment.” Crop potential varies by region, Owens said. However, energycane is well adapted and highly productive in the Deep South.

Life cycle study calculates Algenols algae-to-ethanol process can deliver 67% to 87% reduction in carbon footprint compared to gasoline

Green Car Congress

Algenol Biofuels’ Direct to Ethanol technology is based on an intracellular photosynthetic process in cyanobacteria (blue-green algae) that produces ethanol that is excreted through the cell walls, collected from closed photobioreactors as a dilute ethanol-in-water solution, and purified to fuel grade ethanol. Algenol algae.

TU Graz researchers identify singlet oxygen as major cause of deleterious side reactions in Li-air batteries; suggested approach to counter

Green Car Congress

Rechargeable non-aqueous metal–O 2 (air) batteries have attracted immense interest because of their high theoretical specific energy and potentially better sustainability and cost in comparison to current lithium-ion batteries. The presence of trace water enhances the formation during both discharge and charge. Borisov & Stefan A.

Forecasting the Ice Loss of Greenland’s Glaciers With Viscoelastic Modeling

Cars That Think

This sponsored article is brought to you by COMSOL. The ongoing discharge of ice into the ocean is a “fundamental process in the ice sheet mass-balance,” according to a 2021 article in Communications Earth & Environment by Humbert and her colleagues. However, Earth’s great ice sheets are always moving and evolving.

Researchers Propose Solar-Driven Biomass Gasification Pathway for Synthetic Fuel Production

Green Car Congress

Hydrogen for reverse water gas shift reaction to avoid producing CO 2 during the process is produced by electrolyzing water, driven by solar power. For comparison, they also modeled the production of methanol using only biomass as a fuel and also using coal as source of both carbon and energy. Hertwich and Zhang (2009).
