Ankur Scientific hosted a virtual panel discussion on industrial decarbonisation, focusing on carbon avoidance and carbon capture as twin pathways for hard-to-abate sectors like cement, steel, chemicals, ceramics, and glass. The panel highlighted biomass gasification as a way to replace fossil fuels in high-temperature kilns and furnaces, while producing biochar that can store carbon long term. It also pointed to the Morbi ceramic cluster's fuel supply disruptions as evidence that imported gas dependence is both a climate risk and a business risk. The discussion covered India's Carbon Credit Trading Scheme and the EU's Carbon Border Adjustment Mechanism, noting that emissions now carry a financial cost for Indian industry. Ankur Scientific says its gasifiers run at over 90 percent efficiency, yield more than 25 percent biochar, and can process over 60 feedstocks. The company also reported 1.5 million tonnes of CO2 reduced, 350,000 MWh of green energy generated, and 185,000 tonnes of carbon sequestered since inception. Recent projects include a cement-sector installation, an industrial biochar and steam project, and a cotton stalk biochar carbon removal project in India.

Good writeup on a real constraint: high-temp kilns can't just plug into renewables. The Morbi example ties gas dependence to business risk, not just climate risk. Worth reading for the gasification and biochar numbers, though I'd want more detail on how those efficiency and yield claims are measured.

The 90 percent efficiency and 25 percent biochar yield claims jump out. Those need a defined basis, LHV or HHV, and feedstocks matter a lot. Also curious how the 1.5 million tonnes of CO2 reduction is accounted: avoided vs removed, and over what period?

The CCTS and CBAM angle is the real story. Once emissions carry a price, fuel switching and biochar start showing up in compliance math. But the article doesn't say whether Ankur's projects are generating tradeable credits under CCTS or only pre-approved by Isometric and Rainbow. That distinction matters.

High-temp heat is the part people skip. Gasification makes sense for kilns and furnaces, but the economics depend on feedstock logistics and biochar buyers. The cotton stalk project is a good test case. I'd want payback data before calling it scalable.
