Rainbow launches public consultation for new biomass burial module

Rainbow initiated a public consultation on 21 August 2026 for its new biomass burial carbon storage module, part of its BiCRS methodology. The consultation period for public feedback will conclude on 21 September 2026. This module provides guidelines for credibly storing biomass underground to prevent decay and CO2 release, covering eligible technologies, biomass types, storage sites, and certification requirements. It specifies eligible biomass categories, including woody biomass and thermochemically converted biomass like hydrochar and biochar, and requires storage for at least 100 years in suitable subsurface sites. This development offers a new pathway for permanent CO2 storage for hydrochar and biochar developers.
