 Biochar brings benefits to soils, boosting plant growth |
Green guru James Lovelock claims that the only hope of mitigating catastrophic climate change is through biochar - biomass "cooked" by pyrolysis.
It produces gas for energy generation, and charcoal - a stable form of carbon.
The charcoal is then buried in the ground, making the process "carbon negative".
Researchers say biochar can also improve farm productivity and cut demand for carbon-intensive fertilisers.
There's a flurry of worldwide interest in the technology, but is the hype justified?
