MAN Engines puts first dual-fuel hydrogen-powered engines for workboats into operation

Green Car Congress

MAN Engines recently put its first two dual-fuel hydrogen-powered engines for work boats into serial operation. The engines are twelve-cylinder diesel engines of type MAN D2862 LE448, each with an output of 749 kW (1019 hp) at 2100 rpm. Only the hydrogen injection system (shown here in blue) has been retrofitted.

Auckland Transport begins 2-year trial of hydrogen bus

Green Car Congress

Auckland (NZ) Transport is beginning a 2-year trial of a 3-axle hydrogen fuel cell bus.The trial will assess operational performance how operating costs compare to diesel and electric buses of similar configurations. The bus will be refuelled at the Ports of Auckland with green hydrogen. The trial will cost $1.175 million.

Study finds total greenhouse gas footprint of blue hydrogen “quite high” due to fugitive methane

Green Car Congress

“Blue” hydrogen—produced through steam methane reforming (SMR) of natural gas or coal gasification, but with CO 2 capture and storage—is being described as having low or zero carbon emissions. Even if true though, the use of blue hydrogen appears difficult to justify on climate grounds. For our default assumptions (3.5%

million) of government funding to develop a biogas and hydrogen dual-fuel solution for the Class 66 locomotive. The Freightliner Class 66 locomotives are 3300hp diesel electric mainline units introduced in 1998. A consortium of Clean Air Power and Freightliner has secured almost £0.4 million (US$0.55 Maximum speed is 75 mph.

Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

The engine was also equipped with an electrically driven volumetric pump in the exhaust gas recirculation (EGR) path which gives the freedom to set any desired EGR rate, independently from the pressure ratios across the turbocharger. The common rail pump was externally lubricated by engine oil so that it can handle the low fuel lubricity.

HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

The EU-funded HyMethShip project developed a system that innovatively combined a membrane reactor, a CO 2 capture system, a storage system for CO 2 and methanol as well as a hydrogen-fueled combustion engine to power ships. The bottom part shows how hydrogen for the engine is obtained from methanol in the reactor (blue arrow).
