Limenet SB decided to implement a system of tracking negative CO₂ emissions through the blockchain. The motivation is to give transparency to the customer on the carbon certificate purchased by Limenet. Currently, the blockchain is used by other companies as a decentralized registry of information regarding the purchase or sale of CO₂ credits. In Limenet we have created a system for tracking the production chain of decarbonised hydroxide and then of the stored CO₂. If CO₂ comes from air or is a biogenic CO₂ (biogas), negative emissions are referred to.
For example, starting from a batch of calcium carbonate and biogenic CO₂, we trace its transformation into decarbonised calcium hydroxide and then into negative CO₂ emissions.
This, once certified, becomes an NFT with inside all the industrial information related to its realization.
The customer who buys the NFT can check on the blockchain all the information related to its negative CO₂ emission: from what raw material was produced, to where it was processed, how much electricity it used etc.
The final added value is to give the customer more information about the negative CO₂ certificate. Not only will you know that the certificate is verified by a third party but you will also have detailed information about how it was done.
