Aviation fuel on Cardano
An established relationship

Brazilian state-controlled energy titan Petrobras has unveiled two new Cardano-based blockchain applications that are aimed at making the process of tracing lower-carbon fuels much more efficient.

On Friday, the Cardano Foundation announced that it had worked with Petrobras and the Pontifical Catholic University of Rio de Janeiro’s blockchain research center, Ledger Labs, on applications focused on sustainable aviation fuel (SAF) and Diesel R, Petrobras’ diesel product with renewable content.

The first application aims to solve the problem of proving who is entitled to claim the environmental benefit linked to a specific quantity of SAF.

Cardano is being used as an auditable record of the aforementioned claims with the help of tokens.

First, certificates are checked against CORSIA and other standards. Then, their attributes are tokenized.

The resulting tokens can then be allocated to airlines or individual passenger journeys.

The second Cardano application connects data generated at different stages of the fuel’s lifecycle. The system links cover production, transportation, and eventual use of the renewable fuel.

An established relationship

Petrobras and Cardano have already collaborated before, so this is an extension of their relationship.

The Cardano Foundation first publicly announced a partnership with Petrobras in December 2023. This, however, was an education-focused initiative: Petrobras employees were taught about blockchain concepts and possible enterprise-level applications.

Petrobras was the first Forbes 500 company to use Cardano’s infrastructure.

Cardano technology has also previously been tested by Petrobras for internal administrative purposes.

It is worth noting that Petrobras is not adopting ADA as a payment asset. However, the fact that Cardano’s blockchain is used for infrastructure by such a huge company is also an undeniably notable development.

ADA, Cardano’s native cryptocurrency, was changing hands at roughly $0.245 at press time. It has a market capitalization of about $9.3 billion, according to CoinGecko data.
