Partnering to achieve Net Zero today
We make Net Zero a reality now, not in the distant future, because neither the climate nor your business can afford to wait.
Taking your business, and the planet, to Net Zero
Businesses are struggling to balance affordable energy with reliable green initiatives to reduce emissions and reach their ambitious Net Zero goals.
Onnu builds and manages hubs that manufacture biochar using breakthrough pyrolysis technology. Our operations generate excess energy, and if our hubs are situated close to an energy partner, it can be delivered as a fully sustainable, carbon negative heat or cold energy source for industry.
Why partner
with us
Decarbonisation
Each of our Hubs can annually avoid 1,500 tCO2e emissions and remove 2,000 tCO2e.
Affordable, stable prices
Secure competitive energy rates for up to 10 years.
Managed service
We’ll build and operate the whole thing, so you can concentrate on your buiness.
Stable, sustainable onsite energy
Green Energy Hubs are pyrolysis plants co-located with energy customers and owned and run by Onnu as a fully managed service.
We take local waste biomass and manufacture biochar, enabling us to offer you secure, green energy that is affordable now, and future proofed against price rises in the future.
How is this possible? The production of biochar creates a large volume of excess heat - a typical plant produces up to 2MW of thermal or cold energy - which can be delivered to you as a carbon negative source of energy. Not only this, but the process of manufacturing biochar qualifies for carbon removal credits, which further help to finance the operation and lower the price at which we can supply energy to you.

Carbon removal
Onnu is registered with both Verra and Puro.Earth. We follow the VCS or Puro’s Biochar methodology depending on which is best for the project, both of which secures the highest value Carbon Removal Credits for organisations looking to voluntarily offset their carbon footprint.
