Reaching negative CO2 emissions

Negative CO2 emissions via enhanced silicate weathering in coastal environments

Negative emission technologies (NETs) target the removal of carbon dioxide (CO2) from the atmosphere, and are being actively investigated as a strategy to limit global warming to within the 1.5-2°C targets of the 2015 UN climate agreement. Enhanced silicate weathering (ESW) proposes to exploit the natural process of mineral weathering for the removal of CO2 from the atmosphere. Here, we discuss...

Decreasing Co2 Emissions in Metallurgy

Modern trends in iron metallurgy. Global carbon emissions from iron production. New solution for iron and steelmaking in a way reduce the CO2 emission to the level, where this might be needed in the post Kyoto period. New blast furnace technology, which operate with very low CO2 emissions based on drastically reduced consumption of carbon containing input materials. Injection of reducing gases ...

Harvesting Energy from CO2 Emissions

When two fluids with different compositions are mixed, mixing energy is released. This holds true for both liquids and gases, though in the case of gases, no technology is yet available to harvest this energy source. Mixing the CO2 in combustion gases with air represents a source of energy with a total annual worldwide capacity of 1570 TWh. To harvest the mixing energy from CO2-containing gas e...
