Google Strikes World's Largest Biochar Carbon Removal Deal
Google has partnered with Indian startup Varaha to purchase 100,000 tons of carbon dioxide removal credits by 2030, marking its largest deal in India and the largest involving biochar, a carbon removal solution made from biomass. TechCrunch reports: The offtake agreement credits will be delivered to Google by 2030 from Varaha's industrial biochar project in the western Indian state of Gujarat, the two firms said on Thursday. [...] Biochar is produced in two ways: artisanal and industrial. The artisanal method is community-driven, where farmers burn crop residue in conical flasks without using machines. In contrast, industrial biochar is made using large reactors that process 50-60 tons of biomass daily. Varaha's project will generate industrial biochar from an invasive plant species, Prosopis Juliflora, using its pyrolysis facility in Gujarat. The invasive species impacts plant biodiversity and has overtaken grasslands used for livestock. Varaha will harvest the plant and make efforts to restore native grasslands in the region, the company's co-founder and CEO Madhur Jain said in an interview. Once the biochar is produced, a third-party auditor will submit their report to Puro.Earth to generate credits. Although biochar is seen as a long-term carbon removal solution, its permanence can vary between 1,000 and 2,500 years depending on production and environmental factors. Jain told TechCrunch that Varaha tried using different feedstocks and different parameters within its reactors to find the best combination to achieve permanence close to 1,600 years. The startup has also built a digital monitoring, reporting and verification system, integrating remote sensing to monitor biomass availability. It even has a mobile app that captures geo-tagged, time-stamped images to geographically document activities, including biomass excavation and biochar's field application. With its first project, Varaha said it processed at least 40,000 tons of biomass and produced 10,000 tons of biochar last year. Read more of this story at Slashdot.
