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

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

The process uses relatively little energy and a relatively cheap material—iron sulfide with a trace amount of molybdenum as an additive. Herein, we demonstrate a sulfur looping scheme in a one-reactor system using a low-cost and environmentally safe iron-based sulfur carrier. —Jangam et al.

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

Green Car Congress

The two main components—the electrochemical conversion hardware through which the fluids are flowed (which sets the peak power capacity) and the chemical storage tanks (which set the energy capacity)—may be independently sized. The design permits larger amounts of energy to be stored at lower cost than with traditional batteries.

Simple process for the production of fuel additives from residual forest biomass

Green Car Congress

Researchers at the Université de Sherbrooke, Canada, with colleagues at the Université de Toulouse, France, have developed a process for the direct production of levulinates from cheap residual lignocellulosic biomass using an affordable homogeneous catalyst. A paper on their work is published in Fuel.

Perspective: Drive Star Conversion Program Could Cut US Oil Use in Half by 2020

Green Car Congress

And oil only seems cheap. We’re about to enact the “Home Star” and “Building Star” programs—putting people to work on “Cash for Caulkers” retrofits that will make buildings more comfortable and cut owners’ fuel costs. Cash for Conversions” will start by fixing many of our 100 million trucks, vans, and buses.

New Rutgers non-noble metal catalyst for hydrogen evolution performs as well as Pt in both acid and base

Green Car Congress

Currently, renewable hydrogen may be produced from water by electrolysis with either low efficiency alkaline electrolyzers that suffer 50–65% losses, or by more efficient acidic electrolyzers using expensive rare platinum group metal catalysts (Pt). 2 , equivalent to ~10% solar photoelectrical conversion efficiency.

PNNL team develops bio-inspired iron-based catalyst for hydrogen fuel cells

Green Car Congress

Electrocatalysts are needed for the conversion between chemical energy (bonds such as the H–H bond of hydrogen) and electricity in future systems for the storage and use of energy. Electricity is produced from the oxidation of hydrogen in low-temperature fuel cells, but the best catalyst is platinum, a precious metal of low abundance.
