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. —Howarth and Jacobson.

Rystad Energy expects strong growth in hydrogen pipelines through 2035

Green Car Congress

Independent research and business intelligence company Rystad Energy estimates that there are about 91 planned hydrogen pipeline projects in the world, totaling 30,300 kilometers and due to come online by around 2035. New hydrogen infrastructure is starting to materialize as the world seeks to accelerate its path to net zero.

Rolls-Royce successfully tests 12-cylinder mtu engine with pure hydrogen

Green Car Congress

Rolls-Royce has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. For several months, the mtu gas engine has been undergoing bench testing and continuous improvement in terms of efficiency, performance, emissions and combustion using 100% hydrogen as fuel.

MIT team exploring using LOHCs directly on-board hydrogen-fueled trucks

Green Car Congress

Green, the Hoyt Hottel Professor in Chemical Engineering, is developing a technology that allows liquid organic hydrogen carriers (LOHCs) not only to deliver hydrogen to the trucks, but also to store the hydrogen onboard. Their findings were recently published in the ACS journal Energy and Fuels.

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 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 IMO Tier III-certified and equipped with a Selective Catalytic Reduction exhaust gas aftertreatment system. Only the hydrogen injection system (shown here in blue) has been retrofitted.

Porsche simulates hydrogen V8 for virtual Nordschleife run; 440 kW, 261 km/h, near-zero NOx

Green Car Congress

In a recent simulation study reported in Porsche Engineering Magazine , Porsche Engineering examined the potential of hydrogen combustion engines. Current work on hydrogen combustion engines worldwide is predominantly being done for commercial vehicles with a relatively low specific output of around 50 kW per liter of displacement.
