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%

MAN Engines approves off-road engines for use with regenerative diesel/HVO

Green Car Congress

According to MAN Engines, all MAN off-road engines from the current product portfolio can be operated with regenerative diesel—also known as HVO (hydrogenated vegetable oil)—in accordance with the EN15940 standard in Europe or the US specification ASTM D975.

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

Green Car Congress

The common rail pump was externally lubricated by engine oil so that it can handle the low fuel lubricity. 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.

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).

MAN D3876 engine ensures high thrust and future-proofing in PistenBully 800; engine basis for possible H2 variant

Green Car Congress

In addition, the specialists for off-road engines from MAN Engines optimized the oil pan and oil pump of the MAN D3876. Equipped with the latest exhaust technologies, the MAN D3876 complies with the current and strict EU Stage V emission regulations. This in-line six-cylinder engine with a displacement of 15.3

Hydrogen Opposed Piston Engine Working Group formed

Green Car Congress

Several organizations, encompassing companies, research labs, and academia, have formed the Hydrogen Opposed Piston Engine Working Group. The Working Group consists of members undertaking research and development in the field of hydrogen combustion in an opposed-piston engine. If hydrogen combustion is sufficiently lean—i.e.,

Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

The diesel engine on the Empa test facility was tuned to DME. In contrast to diesel, the highly volatile DME has almost no lubricating qualities, which can quickly destroy the high-pressure pump of a common rail injection system. An electrically driven compressor for precise exhaust gas recirculation is also used. Image: Empa.
