Study finds engines emit exhaust nanoparticles even when not fueled during engine braking

Green Car Congress

Exhaust particle size distributions measured by ELPI (color map) and particle concentration measured by CPC (white line) during individual engine braking conditions (speed change from 32 km/h to 0 km/h). The exhaust sample was taken from the exhaust manifold. The exhaust sample was taken from the exhaust manifold.

Rystad Energy expects strong growth in hydrogen pipelines through 2035

Green Car Congress

The West Macedonia pipeline is a new natural gas pipeline that started construction in Greece earlier this year. HyNet will produce, store, and distribute hydrogen, in addition to capture and store carbon from industry in the Northwest. For this reason, the option to transport power onshore using power cables is excluded.

EU investing >€3M in research into ultra-efficient aero engines; ULTIMATE project

Green Car Congress

The EU is targeting a 75% reduction in carbon dioxide emissions per passenger kilometer between the years 2000 and 2050. Core exhaust loss. The “Core exhaust” loss is primarily due to thermal energy lost to the surroundings, although some excess kinetic energy and fluid friction associated pressure losses contribute as well.

DNV GL paper suggests near-term success for LNG in shipping; alternative fuel mix to diversify over time

Green Car Congress

While renewable energy, particularly solar and wind, may have some potential to mitigate carbon emissions, this is not seen as a viable large-scale alternative for commercial shipping. In this case GHG and other pollutants will still be emitted, but they can be reduced through exhaust gas cleaning systems or carbon capture and storage.
