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

Green Car Congress

To address this, our work is exploring a more efficient application, with LOHC-powered trucks featuring onboard dehydrogenation. On its way to the engine, some of the hydrogen gets diverted to a burner to heat the reactor, which helps to augment the reactor heating provided by the engine exhaust gases. 3c01919

UK researchers report that alcohols in windshield washer fluid are major unreported source of VOCs emissions from cars, including EVs

Green Car Congress

The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g., Resources Samuel J. Cliff et al. Cliff, Alastair C. Lewis, Marvin D. Shaw, James D.
