Waste CO2 turns into stone when pumped into a volcano

Reduce CO2 emission -- CarbFix Project

The increase in carbon dioxide (CO2) emission is a big concern when we talk about global warming. Constrains of CO2 emission is a hot topic but how to do it? Can a volcano help to reduce CO2 emission?

CO2 turned into stone

A group of scientists have recently pumped CO2 and water underground into volcanic rock on Iceland. As a result, CO2 turned into limestone. They injected 220 tons of CO2 and water hundreds of meters down into volcanic basalt. Here it reacted with calcium and magnesium ions to make calcium and magnesium carbonates.

Scientists previously injected pure CO2 into limestone or deep, salty aquifers. However, the fear is always that the CO2 could leak. Now they are working on the Carbfix project in Iceland. They make CO2 solid and therefore it stays in place without leaks.

Reduce CO2 emission in the future

The scientists are excited about the process. The speed of it is surprising, too. Consequently, we may be able to constrain the emission of CO2 in this manner by placing power plants in places with a lot of basalt.

A primary goal of the CarbFix project is to imitate the natural storage process of CO2 already observed in basaltic rocks in Icelandic geothermal fields. The project’s implications for the fight against global warming may be considerable, since basaltic bedrock susceptive of CO2 injections are widely found on the planet.

How can you reduce CO2 emission?
US Environmental Protection Agency has created a tool for those curious about what reducing carbon dioxide (CO2) emissions by 1 million metric tons means in everyday terms. The greenhouse gas equivalencies calculator can help you understand just that, translating abstract measurements into concrete terms you can understand, such as the annual emissions from cars, households, or power plants. This calculator may be useful in communicating your greenhouse gas reduction strategy, reduction targets, or other initiatives aimed at reducing greenhouse gas emissions.
