Hydra Energy, the Hydrogen-as-a-Service (HaaS) provider for commercial fleets looking to reduce emissions and costs with limited risk and no up-front investment ( earlier post ), has delivered its first hydrogen-converted, heavy-duty truck to paying fleet customer Lodgewood Enterprises. Hydra’s technology has been in development since 2012.

Department of Energy (DOE) released a report suggesting that, in theory, over 300 former and present coal power plants could be converted to nuclear. Such a conversion has never been done, but the report is another sign that the idea is gaining momentum—if with the slow steps of a baby needing decades to learn to walk. “A

Panasonic has developed an artificial photosynthesis system using a gallium nitride photoelectrode and a metal catalyst which uses sunlight to convert CO 2 mainly to formic acid (an important intermediate in chemical synthesis) at an efficiency (solar energy to chemical energy) of 0.2%—a Click to enlarge.

The four-cylinder TDI engine with the internal designation EA 288 made its debut in 2012. Volkswagen opted for a dual strategy: detailed measures optimized the combustion process and reduced raw emissions, while twin dosing technology in the exhaust gas system converted the majority of NO x into harmless substances.

Devising efficient catalytic processes to convert methane into useful petrochemical feedstocks depends upon developing new coupling processes that use abundant, thermodynamically mild oxidants together with selective catalysts. Sulfur as a selective “soft” oxidant for catalytic methane conversion probed by experiment and theory.

The technical reason for these high “off-cycle” NO x emissions is poor NO x conversion efficiency of installed SCR systems when exhaust temperature is low. Urea-driven SCR system use exhaust heat to convert the urea solution to ammonia, which then reduces the NO x. At low exhaust temperatures, catalyst activity also falls off sharply.
