  • With a vision to create a conducive environment by reducing carbon emissions and nurture technology solutions in India, the Green Charcoal Hackathon on Dec 01,2020 was launched by NVVN (NTPC VidyutVyapar Nigam) , a wholly-owned subsidiary company of NTPC Ltd on Dec 1,2020.
  • Green Hackathon is a technology challenge being organized by NVVN, in partnership with EESL.
Green Charcoal Hackathon

Hackathon Overview and Objectives

  • The engineers have been asked by NTPC management to present innovative and new ideas.
  • To fast-track the technology development.
  • Leveraging the innovative Indian minds to bridge the technology gap.
  • To clean the air by eliminating farm fire.
  • Innovation in the pursuit of reducing our carbon footprint.
  • Emissions should not be there due to the process conversion of agro residue to charcoal.

The commercial model depends on the cost of:

  • Machine production.
  • Charcoal production.


  • Increasing air pollution due to the burning of stubble and agro residue by local farmers.
  • Power plants are the biggest consumers of coal.
  • Annually, a 1000 MW plant consumes about 5 million tonnes of coal.
  • The total coal-based power generation capacity of India is about 2 lakh MW.
    • Approximately 1000 million tonnes of coal annually can be consumed.
  • Replacement with green charcoal will amount to 100 million tonnes of the fuel (Approximately 160 million tonnes of agro residue and municipal waste will be required) , considering 60 % yield.
  • The entire unused agro residue in the country can be wiped out.
    • Eliminating farm fires.
    • Produce approx. 20,000 MW of renewable power and generating a revenue worth 50,000 crore per year.


  • It is planning to develop technologies that can convert agricultural waste to a form such that it can be used in the power plants.
  • Torrefaction is a technique that can convert the agro residue to green charcoal.
  • Due to the higher cost of imported machines and lack of sufficient manufacturers, small entrepreneurs don՚t have the easy accessibility of technology to produce torrefied fuel using agro residue biomass.
