Policy support could unlock biochar use: Industry

  • Market: Biomass, Emissions

Increased use of biochar and biocarbon is being held back by economics rather than a lack of demand or technology, and targeted policy support could make projects viable, delegates heard at the International Biomass Conference last week.

The industry is not asking for large subsidies, but rather limited, well-targeted government incentives to bridge early adoption, panellists said at the event in Nashville, Tennessee.

Demand for biochar-based carbon dioxide removal (CDR) credits exceeds available supply, especially in the US, but finding end users for physical biochar is the hardest part of project development, German firm Carbonfuture's head of business development for Americas, Julie Mansfield, said. "We have buyers coming to us weekly looking for biochar CDR credits in the US, and when those credits come to market, they are gone almost immediately," Mansfield said.

Large-scale agriculture represents the "real opportunity" for biochar applications, US project developer Oregon Biochar Solutions' chief operating officer, Karl Strahl, said. But Strahl also recognised real barriers in that sector, saying that it requires "a lot more education and product development".

Industrial applications for biochar are seen as more scalable in the near term, with the steel and cement industries able to absorb large volumes. But while the technologies for biochar production are now largely proven, reliability and scalability are still challenging for several suppliers. "Steelmakers want consistency, they want thousands of tonnes, not one successful trial," Canadian firm Char Technologies' chief executive, Andrew White, said.

Panellists agreed that revenues from CDR credits alone are insufficient to scale up projects and that they require multiple revenue streams and policy support. "If you are producing high fixed-carbon material, your yield is lower, so you have to find value in the gases as well," White said.
