New study confirms extensive gas leaks in the North Sea; recommends stricter guidelines for handling of abandoned wells

Green Car Congress

Researchers from the GEOMAR Helmholtz Center for Ocean Research Kiel have found that considerable quantities of the greenhouse gas methane escape uncontrolled into the water from abandoned oil and gas wells in the North Sea. Methane is the second most important greenhouse gas after carbon dioxide.

KIT team designs low-cost photoreactor for efficient solar-driven synthesis

Green Car Congress

Different photocatalysts can be used, for example, to split water into hydrogen and oxygen, but climate-neutral fuels can also be produced from water and carbon dioxide, says Paul Kant from the Institute of Microprocess Engineering (IMVT) of KIT. The photocatalyst is then integrated into the presented photoreactors.

Mercedes-AMG 2L, turbo four-cylinder pushes out up to 421 hp, 500 Nm

Green Car Congress

Fresh air is used in addition to oil and water to cool the turbocharger. Thanks to its good thermal conductivity, the water-cooled mould allows rapid cooling and solidification of the melt. The cooling performance was also improved by a near-surface water jacket geometry, a faster flow rate and an optimized volumetric flow rate.
