We see biomass pyrolysis and biochar as the most accessible and scalable of all engineered carbon removal processes, thanks to its relative simplicity, and ability to support profitable business models.
To ensure this sector thrives, and can have a game-changing impact in the fight against climate change, Onnu seeks to remove barriers to scaling, both for our own business and others, to expand and grow the market.
By 2030 we will have played our part building a world where no biomass is wasted, pyrolysis routinely generates localised green energy, biochar use is widespread and biochar CDR is removing mega tonnes of CO2 from the atmosphere.
Our CarboFlow technology delivers clean energy, while capturing carbon, manufacturing biochar and investing in local circular economies.
By 2030, we aim to have facilitated the annual delivery of:
of carbon
removed
biochar
manufactured
of clean energy generated
operational pyrolysis sites
