Three-part catalyst study advances conversion of CO2 to ethanol

Green Car Congress

An international collaboration of scientists has taken a significant step toward the realization of a nearly “green” zero-net-carbon technology that can efficiently convert CO 2 and hydrogen into ethanol. None of the three components examined in the study is able to individually catalyze the CO 2 -to-ethanol conversion, nor can they in pairs.

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 result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals.

Fraunhofer analysis finds battery-electric trucks have energy cost advantage over hydrogen trucks

Green Car Congress

In a recent analysis, Fraunhofer ISI concludes that battery-electric drives will become established in heavy-duty applications in the commercial vehicle sector and that fuel cells will remain a niche application. The decisive factor for the switch to battery-electric vehicles is the energy cost advantage compared to hydrogen and diesel.

UNSW Syndey team develops hydrogen-diesel dual fuel system; 90% H2, more than 85% reduction in CO2

Green Car Congress

Engineers from UNSW Sydney (Australia) have successfully converted a diesel engine to run as a dual-fuel hydrogen-diesel engine, reducing CO 2 emissions by more than 85% compared to conventional diesel. In a paper published in the International Journal of Hydrogen Energy, Prof. below the amount produced by the diesel powered engine.

Haldor Topsoe to build large-scale SOEC electrolyzer manufacturing facility to meet customer needs for green hydrogen

Green Car Congress

With efficiencies above 90%, Topsoe’s proprietary SOEC electrolyzers offer superior performance in electrolysis of water into hydrogen—e.g., Solid oxide electrolysis cell (SOEC) technology is attractive because of unrivaled conversion efficiencies—a result of favorable thermodynamics and kinetics at higher operating temperatures.

PNNL team develops least costly to date carbon capture system with conversion to methanol

Green Car Congress

The new PNNL carbon capture and conversion system brings the cost to capture CO 2 down to about $39 per metric ton. The catalysts commonly used for gas-phase CO 2 hydrogenation (e.g., Methanol produced via CO 2 conversion could qualify for policy and market incentives intended to drive adoption of carbon reduction technologies.

New proton ceramic reactor stack for highly efficient hydrogen production and carbon capture in a single step

Green Car Congress

The team has also demonstrated that the process can be scaled up for commercial application. Proton ceramic electrochemical reactors can extract pure hydrogen from gas mixtures by electrolytically pumping protons across the membrane at 800 °C. The end product is compressed hydrogen with a high degree of purity.
