Energy Quest, Inc., an organization working on the development, construction and marketing of low-cost alternate fuels worldwide has said that its gasification process can produce biochar from agricultural wastes and other biomass, as per a press release.The process employs simple changes like speeding up the biomass fuel and adjusting the process parameters to increase the content of carbon in the solid residue generated from gasifier and provide high quality agricultural grade soil amending biochar.
A modular gasification bio-energy plant consuming 10 to 12 tonnes per hour of agricultural waste biomass available locally can produce 16 to 18 thousand tonnes of biochar per year. According to Christoph Steiner, a University of Georgia research scientist in the Faculty of Engineering comments, "The potential of biochar lies in its ability to sequester-capture and store huge amounts of carbon while also displacing fossil fuel energy, effectively doubling its carbon impact. Scientists estimate biochar from agriculture and forestry residues can potentially sequester billions of tons of carbon in the world's soils."
Production of biochar from a gasifier can slash the set up costs and increase the efficiency and also provide clean syngas fuel for heat and power generation.
