PNNL team develops new low-cost method to convert captured CO2 to methane

Green Car Congress

By using a water-lean post-combustion capture solvent, (N-(2-ethoxyethyl)-3-morpholinopropan-1-amine) (2-EEMPA), they achieved a greater than 90% conversion of captured CO 2 to hydrocarbons—mostly methane—in the presence of a heterogenous Ru catalyst under relatively mild reaction conditions (170 °C and 2 pressure). Heldebrant, D.,

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Wide-scale utilization of flow batteries is, however, limited by the abundance and cost of these materials, particularly those using redox-active metals and precious-metal electrocatalysts. The design permits larger amounts of energy to be stored at lower cost than with traditional batteries. —Huskinson et al. Background.

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

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. The process is constrained by the (low) cost of electricity. The initial synthesis pathways, however, led only to short CNTs. —Johnson et al.

KIT team designs low-cost photoreactor for efficient solar-driven synthesis

Green Car Congress

Researchers from the Karlsruhe Institute of Technology (KIT) and their Canadian partners have designed a low-cost photoreactor design for solar-driven synthesis. The photoreactors have a low level of complexity, are readily manufacturable via mass fabrication techniques in polymers, and are easy to adapt to diverse photocatalysts.

New catalysts convert ethanol to butanol with high selectivity; potential low-cost upgrade for ethanol plants

Green Car Congress

Researchers at the University of Bristol (UK) have developed a new family of catalysts that enables the conversion of ethanol into n-butanol—a higher alcohol with better characteristics for transportation applications than ethanol—with selectivity of more than 95% at good conversion. —Professor Duncan Wass.
