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. Different methods for converting CO 2 into methane have long been known. A paper on the work is published in ChemSusChem.

Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

and Princeton University’s Andlinger Center for Energy and the Environment have created a scalable photocatalyst that can convert ammonia into hydrogen fuel. This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants. —co-author Naomi Halas.

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.

Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

The conversion rate reaches 32.9 ± 1.38 This one-step nitrogen-fixation strategy to produce ammonia is eco-friendly and low cost, which converts widely available starting materials into a value-added product. Xiaowei Song, a postdoctoral scholar in chemistry at Stanford, is the lead author of the study.

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

Green Car Congress

Herein, we demonstrate a sulfur looping scheme in a one-reactor system using a low-cost and environmentally safe iron-based sulfur carrier. Compared with the undoped sulfur carrier, Mo dopant facilitates the surface hydrogen diffusion, thus promoting the overall H 2 S conversion. —Jangam et al.

US researchers demo separation-free, IL-based process for conversion of biomass to advanced biofuel

Green Car Congress

Researchers from three US national labs (Berkeley, Pacific Northwest and Sandia) has demonstrated a separation-free, ionic-liquid (IL)-based process to convert biomass to an advanced biofuel (the sesquiterpene bisabolene). —Sundstrom et al. This is also the first such demonstration with R. —Sundstrom et al.
