New catalyst improves conversion of CO2 to syngas

Green Car Congress

Researchers from the University of Illinois at Chicago (UIC) have identified molybdenum disulfide as a promising cost-effective substitute for noble metal catalysts for the electrochemical reduction of carbon dioxide. Carbon Capture and Conversion (CCC) Catalysts Fuels' Fine-tuning of the edge structures is relatively simple.

Advances in the conversion efficiency of thermoelectric materials

Green Car Congress

A collaboration including researchers from Boston College, MIT, the University of Virginia and Clemson University have achieved a peak ZT (thermoelectric figure of merit) of 0.8 And a team from Northwestern University and the University of Michigan reported experimentally achieving a ZT of 1.7 The study by Yan et al.

New study finds key trade-off of algae-to-energy systems for transportation: excellent land use efficiency, but with mixed environmental burdens

Green Car Congress

The team also suggested that algae systems can be either net energy positive or negative depending on the specific combination of cultivation and conversion processes used. Unit operations pertinent to assessment of four specific conversion pathways are shaded (gray) in panels A-D at bottom. Credit: ACS, Clarens et al. Earlier post.)

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

Model scope includes all upstream processing of biomass material; conversion to liquid or solid fuel is intentionally excluded. For all crops, the entire plant was used to facilitate comparison on a total energy basis. Biofuel conversion processes were excluded from the scope of the analysis.

Tsinghua Researchers Find that Sugarcane Juice is a Good Fermentation Feedstock for Algal Biodiesel

Green Car Congress

Researchers at Tsinghua University in China have shown that sugarcane juice is a good feedstock for biodiesel production, when used to support the growth of the alga Chlorella protothecoides by heterotrophic fermentation. Conversion ratios of sugar/biomass and sugar/oil using SCH were 15.2 Energy Fuels , Article ASAP.

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

Green Car Congress

Researchers at the Norwegian University of Science and Technology (NTNU) are proposing a new process for producing synfuel from biomass using concentrating solar energy as its main energy source. 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.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Researchers at George Washington University led by Dr. Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes).
