“From a business community perspective, given the whole energy demand for India, there is a huge demand for coal,” says Komarina.
“The use of coal is inevitable, but then how do you make it more sustainable?
One of the case studies in Yes Bank’s sustainability report regards “Coldry”, a technology brought in from Australia to make India’s lignite cleaner to burn.
It works by drying out the lignite, a brown variety of coal with high moisture content, before using it to generate power.
That results in coal with 280% higher calorific value, it claims, generating “substantially lower” greenhouse gas emissions than lignite in its natural form.
While it is far from the lowest carbon way of generating electricity, it makes a cheap source of fuel a bit less dirty.
