India's double first in climate battle
India opens two world-leading clean energy projects - the world's biggest solar farm and a chemicals plant using CO2 to make baking soda.
Two world-leading clean energy projects have opened in the south Indian state of Tamil Nadu.
An industrial plant is capturing the CO2 emissions from a coal boiler and using the CO2 to make valuable chemicals. It is a world first.
And just 100km away is the world’s biggest solar farm, making power for 150,000 homes on a 10 sq km site.
The industrial plant appears especially significant as it offers a breakthrough by capturing CO2 without subsidy.
Built at a chemical plant in the port city of Tuticorin, it is projected to save 60,000 tonnes of CO2 emissions a year by incorporating them into the chemical recipe for soda ash - otherwise known as baking powder.
