Science behind
Current state-of-the-art
Mineralisation of CO2 through the weathering of silicate minerals process has moderated global climate for billions of years, and currently consumes 0.3 GT of CO2 annually directly from the atmosphere.
Mineral storage at the Earth’s subsurface has been demonstrated by Carbfix1 in Iceland, where CO2 is injected into basalt, a common volcanic rock, and converted into stable mineral within 18 months.
Our approach – moving forward the state-of the-art
Carbonation in 18 months is too slow for most industrial emission streams. To make the process viable at a factory, the mineralisation reaction needs to occur within 2 hours.
We develop and use geocatalysts, natural biogenic compounds, to accelerate the reaction and to control the end products.
In our process, we use building waste, e.g. crushed concrete, stone wool, similar to basalt - keeping these materials from landfills.
We take full advantage of top research facilities at DTU.
