Hero Future Energies, the renewable energy arm of Hero Group, will establish its e-methanol plant in Harihar at Davangere, a project estimated to cost about Rs 20,000 crore. 

Hero Future Energies chairperson and managing director Rahul Munjal discussed the project with Karnataka Chief Minister Siddaramaiah. 

Munjal sought government support and "the same was assured", CM's Additional Chief Secretary LK Atheeq said.

"This (plant) will capture carbon from smoke emitted by industry, combine it with hydrogen and manufacture e-methanol, which is used as a green fuel," Atheeq explained, adding that the process requires water to "ionise and obtain" hydrogen.

The proposed e-methanol plant plans to use emissions from the Viscose Staple Fibre manufacturing unit of Grasim Industries, the flagship company of the Aditya Birla Group.
