GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

The process is constrained by the (low) cost of electricity. Initial scaling is efficiently applied to available concentrated, hot sources of CO 2 , such as eliminating the CO 2 emission from industrial smoke stacks and simultaneously forming valuable CNT wool. —Johnson et al.

Fraunhofer ISI/ICCT analysis of PHEV data finds real-world CO2 emissions 2-4x higher than official values

Green Car Congress

A new analysis of the real-world usage of more than 100,000 plug-in hybrid electric vehicles shows a large deviation between on-road CO 2 emissions and fuel efficiency and the official vehicle type-approval values. The researchers also took into account data on company cars that had been provided by fleet managers.

USC, NREL team develops sustainably produceable nanoparticle for thermocatalytic CO2 hydrogenation; emissions into fuels

Green Car Congress

The particles can be produced at an industrial scale at a low cost, and with minimal environmental impact, providing an attractive pathway toward reducing the world’s greenhouse emissions. Baddour from NREL and Richard Brutchey, professor of Chemistry at USC. —Noah Malmstadt.

8 Rivers announces 8RH2 CO2 Convective Reformer for ultra-low carbon hydrogen production from natural gas

Green Car Congress

The Allam-Fetvedt Cycle is a new type of power cycle that takes a novel approach to emissions reduction. It uses the oxy-combustion of carbon fuels and a high-pressure supercritical CO 2 working fluid in a highly recuperated cycle that captures all emissions by design. Clean Power: transformative zero-emissions power cycles.

DOE awards $3M for 10 high-performance computing projects to improve energy efficiency and material performance

Green Car Congress

DOE’s Advanced Manufacturing Office has selected seven projects in the HPC4Mfg program focused on the following topics: Reductions in CO 2 or CO 2 -equivalent emissions through electrification, improved carbon-capturing processes, and the integration of low-to-zero carbon fuels. and carbon emissions reduction of products of interest.

GWU team suggests C2CNT carbon nanotube composites could amplify reduction of GHG emissions

Green Car Congress

The latter (B) includes a cascade effect due to virgin Al’s large carbon footprint, triggering larger CNT-composite induced CO 2 emission elimination. Furthermore, the removed CO 2 is permanently stored, unlike, other methods like the production of fuels or seltzer water that re-release CO2 when the product is used. Licht et al.

Santos reports successful CO2 capture and storage injection trial in Moomba CCS project

Green Car Congress

Gallagher said that this successful test, along with recent Federal government announcements, paves the way for large-scale CCS to drive down Australia’s carbon emissions.
