Study: expanding Brazilian sugarcane for ethanol could reduce global CO2 emissions by up to 5.6%

Green Car Congress

However, it could be accomplished without impinging on environmentally sensitive areas in Brazil and while allowing for the expansion of other agricultural crops and human needs, the researchers report in a paper in the journal Nature Climate Change. million and 116 million hectares (144,788 to 447,879 square miles). Gigatons yr −1.

Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

STEP is an efficient solar chemical process, based on a synergy of solar thermal and endothermic electrolyses, designed to convert greenhouse gas carbon dioxide into a useful carbon commodity. This presents a sustainable route to convert carbon dioxide into materials relevant to both grid-scale and portable storage systems.

GTI quantifies opportunity to produce low-carbon renewable natural gas (RNG) from wood wastes

Green Car Congress

GTI led a team of engineers and scientists to produce a blueprint for converting an existing biomass facility into an RNG production site, using the wood waste feedstock and some of the existing infrastructure. GTI has released a site-specific engineering design titled “ Low-Carbon Renewable Natural Gas (RNG) from Wood Wastes ”.

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

Green Car Congress

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). This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. Licht et al.

Researchers combining CO2 storage and geothermal energy production

Green Car Congress

The CO 2 will then be pulled to the surface and fed into a turbine that converts heat into electricity. Our planned demonstration is the first attempt at proving that we can simultaneously mitigate greenhouse gas induced climate change and generate clean baseload power using geothermal energy.

Co-Electrolysis of CO2 and H2O for the Production of Liquid Fuels

Green Car Congress

The Lenfest/Risø team notes that high temperature electrolysis makes very efficient use of electricity and heat (near-100% electricity-to-syngas efficiency), provides high reaction rates (no need for precious metal catalysts), and the syngas produced can be catalytically converted to hydrocarbons in well-known fuel synthesis reactors (e.g.

Pew Environment Report Says Melting Arctic Could Cost a Minimum of $2.4 Trillion by 2050

Green Car Congress

Rapid melting of the Arctic region could carry a minimum global cost of US$2.4 trillion by 2050, according to a new report, “An Initial Estimate of the Cost of Lost Climate Services Due to Changes in the Arctic Cryosphere”, released by the Pew Environment Group. By 2050, this number rises to a cumulative range of $2.4
