Multiple sources of aerobic methane production in aquatic ecosystems include bacterial photosynthesis

Aquatic ecosystems are globally significant sources of the greenhouse gas methane to the atmosphere. Until recently, methane production was thought to be a strictly anaerobic process confined primarily to anoxic sediments. However, supersaturation of methane in oxygenated waters has been consistently observed in lakes and the ocean (termed the ‘methane paradox’), indicating that methane can be produced under oxic conditions through unclear mecha…

A new study shows unexpectedly strong methane emissions in Lake Siljan. Such long-term and concentrated emissions have never been observed at a lake. The researchers will now investigate whether the emissions are unique or whether the phenomenon can occur worldwide. – It is possible that we have only seen the tip of the iceberg, says Professor Johan Mellqvist.

Wärtsilä Launches Methane Slip Reduction Tech for 50DF Engines - mfame.guru

New Spark Gas Tech Cuts Methane Emissions by 75% in LNG Engines. Wärtsilä 50DF Upgrade Slashes Methane Slip with Spark Gas Conversion. Wärtsilä and Chevron Team Up to Cut LNG Methane Emissions. Technology company Wärtsilä has introduced a novel methane slip reduction solution for its Wärtsilä 50DF dual-fuel (DF) engines. The technology allows the DF engines to be converted to spark gas (SG) operation, which provides an optimised combustion proce…
