thyssenkrupp greenlights construction of €2B hydrogen-powered direct reduction plant for low-CO2 steel

Green Car Congress

thyssenkrupp will build a €2B hydrogen-powered direct reduction plant at its Duisberg site. As part of its tkH2Steel transformation project, coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants. In this way, thyssenkrupp is accelerating the start of low-CO2 steel production. Capacity will be 2.5

Project HyTime demonstrates potential for major CO2 savings from hydrogen dual fuel

Green Car Congress

More than 14 tonnes of CO 2 was saved in a two-year trial involving just 11 urban trucks and vans running on green hydrogen dual fuel. That is one result of the Low Emission Freight and Logistics Trial (LEFT) project to investigate the practical deployment of hydrogen powered vehicles in the UK.

UD team devises CO2 direct air capture device powered by hydrogen for HEMFCs

Green Car Congress

University of Delaware engineers have demonstrated an effective way to capture 99% of carbon dioxide from the ambient air feed to an hydroxide exchange membrane fuel cell (HEMFC) air using a novel electrochemical system powered by hydrogen. It’s risky, but we managed to control this short-circuited fuel cell by hydrogen.

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.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.

Novel membrane-free Mg-CO2 battery sequesters CO2 and generates electricity

Green Car Congress

The newly-developed MF Mg-CO 2 battery operates based on the indirect utilization of CO 2 with facile hydrogen generation process, which leads to electrochemical performance of 64.8 Unlike existing aqueous metal-CO 2 systems, the new battery is not only easier to manufacture, but also allows continuous operation with one type of electrolyte.

Oxford team directly converts CO2 to jet fuel using iron-based catalysts

Green Car Congress

The catalyst shows a carbon dioxide conversion through hydrogenation to hydrocarbons in the aviation jet fuel range of 38.2%, with a yield of 17.2%, and a selectivity of 47.8%, and with an attendant low carbon monoxide (5.6%) and methane selectivity (10.4%). The final product is usually a crystallized material.
