Biochar and Soil Carbon Sequestration

Detailed overview of innovation with sample startups and prominent university research


What it is

Biochar is a stable, charcoal-like material produced from the heating of biomass in a low-oxygen environment, a process called pyrolysis. When added to soil, biochar acts like a sponge, holding onto water and nutrients while providing a habitat for beneficial microorganisms. It also offers a remarkable ability: sequestering carbon for centuries, effectively locking it away from the atmosphere and mitigating climate change.

Impact on climate action

Biochar and Soil Carbon Sequestration revolutionizes climate action by enhancing carbon sink management. By utilizing biochar, a stable form of carbon, in soil, it sequesters atmospheric carbon, mitigating climate change effects. This innovation fosters sustainable agriculture, reduces greenhouse gas emissions, and promotes soil health, advancing global climate resilience.

Underlying
Technology

  • Pyrolysis Technology: The process of creating biochar involves heating biomass, such as agricultural residues, forestry waste, or sewage sludge, in a specialized reactor called a pyrolyzer, under limited oxygen. This process breaks down the biomass, producing biochar, bio-oil, and syngas, each with various potential applications.
  • Soil Carbon Sequestration: Biochar’s stable structure makes it resistant to decomposition, allowing it to remain in the soil for hundreds or even thousands of years. The carbon captured within the biochar is effectively sequestered, removing it from the atmosphere and contributing to long-term carbon storage.
  • Enhanced Soil Health: Biochar acts as a soil amendment, improving:
    • Water Retention: Its porous structure holds onto water, reducing water stress on plants and improving drought resilience.
    • Nutrient Cycling: Biochar can bind nutrients, preventing their loss through leaching and making them more available to plants.
    • Microbial Activity: Biochar provides a habitat for beneficial microorganisms, promoting a healthy soil ecosystem.
