Sasol, GE develop new anaerobic microbial technology for cleaning of Fischer-Tropsch waste water; boosting gas-to-liquids (GTL) value proposition

Green Car Congress

Sasol and General Electric (GE: NYSE)’s GE Power & Water have together developed new technology that will clean waste water from Fischer-Tropsch plants used to produce synthetic fuels and chemicals, while also providing biogas as a by-product for power generation. The treatment of GTL-derived effluents is complex and challenging.

AHEAD proposing carbon-free ammonia fuel strategy to bring electricity rapidly to developing countries

Green Car Congress

The AHEAD concept for bringing power to off-grid areas in Africa is to make modest use of renewables where it makes sense, and to drive mass deployment of ammonia and hydrogen along with small engine generators, microturbines and fuel cell systems. Coal and water could be used as input where natural gas is not available.

Study finds climate impact of hydropower varies widely

Green Car Congress

The team found that hydropower emissions on average were far greater and thus worse for the climate than emissions from nuclear, solar and wind power installations, but better for the climate than emissions from coal and natural gas utilities.
