A method for absorbing hydrogen in a crankcase of a hydrogen internal combustion engine is provided, comprising injecting, by a hydrogen injector, hydrogen into a combustion chamber of the hydrogen combustion engine; wherein a piston of the hydrogen combustion engine is configured to compress and expand the hydrogen injected into the combustion chamber; injecting, by a nozzle, a hydrogen carrier medium into the crankcase for hydrogenation of the carrier medium inside the crankcase with hydrogen leaked from the combustion chamber past a side wall of the piston into the crankcase; collecting, by a collector, the hydrogenated carrier medium from the crankcase; heating, by a heater, the hydrogenated carrier medium for dehydrogenation of the carrier medium and extracting hydrogen from the hydrogenated carrier medium; and injecting, by the nozzle, the dehydrogenated carrier medium into the crankcase for hydrogenation. The present disclosure further provides a system for a motor vehicle, and a motor vehicle comprising the inventive system.

A system and method for treating an engine exhaust is provided. In particular, waste heat from an engine exhaust is stored in a latent heat storage structure through a controllable heat exchanger and a selective catalytic reduction (SCR) catalytic converter is heated by the stored thermal energy in the latent heat storage structure using the controllable heat exchanger. The exhaust treatment system includes a selective catalytic reduction catalytic converter that has an inlet for connecting to an internal combustion engine to intake an engine exhaust and an outlet to output a catalytically treated engine exhaust. The system further includes a latent heat storage structure and a controllable heat exchanger for selectively exchanging heat to and from the catalytic converter and the latent heat storage structure.
