System & Technology

The System and Technology

The system removes sky carbon and puts it into soils for millennia. ECOERA traces the carbon and provide carbon removal as a service, based on the system. Customers are granted ownership of the carbon removal and a certificate linked to the audit trail to prove the ownership of the carbon dioxide equivalents embodied in form of millennia stable biochar carbon sequestered in Swedish soil.

The carbon removal is of highest quality and stability. The carbon removed has a beyond thousand-year stability. The carbon stability in the biochar is third party verified through being compliant with the strict standards of the European Biochar Certificate. 

How does it work?

The system starts with pyrolysis of pelletized unique biomass blends with specified mineral composition, thereby producing heat and biochar. The process gas is used for district heating and the biochar is returned to the fields as a soil enhancer and carbon sink. This is a true example of carbon capture, use and storage (CCUS)

ECOERA has created a platform with complete carbon audit trail for following the carbon from biomass to soil and its exact location and amount including analysis data. The process generates a Carbon Removal from Biochar Negative Emissions (CRBN) certificate for purchase. One CRBN equals one metric tonne of CO2 removed from the atmosphere. This is currently for sale as a CORC via the platform.



The complete ECOERA Millennium(TM) Carbon Removal system provides for a method of decreasing atmospheric CO2 and constitutes an easily quantifiable way of measuring CO2 sequestration, thereby creating a market for carbon removal. The biochar carbon has stability beyond 1000 years. The O/Corg ratio is at 0,042 which is scientific proof that the sequestered carbon in the biochar has half-life of beyond 1000 years. H/Corg ratio is 0,21

Reference for the values above:

The typical customer is an individual, company or organization purchasing carbon removal to make its operations truly carbon neutral – not only decreasing emissions somewhere else but actually sequestering the carbon from the atmosphere. Or as we say; Carbon negative is climate positive.

ECOERA conducted the first large scale biochar carbon sequestration by applications of biochar to Swedish farmland.

The application of biochar also generated agricultural benefits and showed a 9,6% increase in plant height (Spring Barley, clay soil, mineral fertilizer) for the 2009 biochar carbon sequestrations and a 33% increase in harvest yield from dry sandy soils from the 2010 sequestrations. This trial was made with external consultant stemming from the Swedish Agricultural Society to verify the trial. The trial was conducted using the Skånefrö Biokol from pellet recipe R54 in six rows with double sampling and made by a Sampo 2010 sampling harvester. When increasing the biochar application from 1 to 3 kg/m2 - all other parameters equal.  In addition to this, pot trials (Tomato: totem) have been successful. 39% tomato yield compared to control. The 2011 trials showed a 33% crop yield increase in the long-term biochar field application. The 2012 and the concluding 2013 large-scale field trial has shown a continuous positive effect in the soil with harvest increase of 9% in 2013 and 14% in 2013.
