The test at Brennels in Noordoostpolder to reduce the greenhouse effect with the mineral olivine is progressing well. This is according to professor Olaf Schuiling of Utrecht University. Olivine is a common mineral (base) and in combination with water and CO2 (acid) it enters into a chemical reaction. And forms a chalky solution in which the CO2 is stored. Schuiling has requested to observe the test at Brennels for another year. According to the professor, olivine is a solution to climate change. According to Schuiling on broadcaster Flevoland.
