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

Green Car Congress

Researchers at the Department of Energy’s Pacific Northwest National Laboratory have developed a new method to convert captured CO 2 into methane, the primary component of natural gas. Conventionally, plant operators can capture CO 2 by using special solvents that douse flue gas before it’s emitted from plant chimneys. Heldebrant, D.,

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

DETA, a chemical bound inside the porous melamine, grabs CO 2 and removes it from the gas, with nitrogen vented to the atmosphere. millimoles per gram at 1 bar), fast adsorption time (less than 1 minute), low price, and extraordinary stability to cycling by flue gas.

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. Carbon dioxide is the sole reactant in this CNT transformation, providing a financial impetus for the removal of this greenhouse gas. —Johnson et al.

DOE selects 7 gasification projects for funding; focus on reducing cost of coal conversion

Green Car Congress

The projects conducted through this program are geared toward reducing the cost of coal conversion and mitigating the environmental impacts of fossil-fueled power generation. The successful implementation of two-phase DFE is expected to result in improved separation efficiency and reduced operating costs for cryogenic air separation.

GWU team develops low-cost, high-yield one-pot synthesis of carbon nanofibers from atmospheric CO2

Green Car Congress

A team led by Dr. Stuart Licht at The George Washington University in Washington, DC has developed a low-cost, high-yield and scalable process for the electrolytic conversion of atmospheric CO 2 dissolved in molten carbonates into carbon nanofibers (CNFs.) —Ren et al. —Stuart Licht.

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.
