OTCnLNG: A single origin of truth to provide LNG buyers and sellers with a decentralized interoperable view of carbon-neutral LNG cargoes 

The carbon neutrality of Liquified Natural Gas (LNG) cargo proceeds from an amount of greenhouse gas emissions (GHG) compensated by carbon credits certified by an organization deriving from CO2 reduction projects, such as reforestation.

We offer new capabilities to tackle issues actors are dealing with by generating transparent, traceable, accountable, secure data management for LNG buyers and sellers, responsible sourcing, and green LNG products. LNG has a Premium if it is monitored (transparency), transferred (frictionless), priced/valued (fair), integrated (externals), and verified (trustworthiness). Secure, accountable, and trustworthy monitoring are keys to reinforcing energy efficiency management actions on the sustainability of LNG itself by verifying the source of provenance (LNG cargo) and offsets.

Users will transact carbon-neutral LNG in a secure & private exchange with a verified identity information, strengthened by distributed semantic energy data management and energy data science.

Our solution triggers positive social and environmental impacts to sustain green energy, provide innovative business models, address civil society expectations, and fulfill industrial gas consumers' needs at the EU level and beyond.






Motivation for the project:

Reusability and trustworthiness of the gathered data will be increased thanks to the key role of domain-specific ontologies for streamlining heterogeneous data integration and assuring data quality in robust data processing and pipeline. ONTOCHAIN provides essential components to build trustworthy applications, and can be used as a digital hub.

Generic use case description:

LNG buyers and sellers will profit benefit from marketing the digital asset using their exchanges and scale by offering carbon credits at a lower price than their customers would acquire. They will also be able to monitor and track their journey to carbon neutrality. 

Essential functionalities:

- Digital Asset for LNG life cycle management
- Digital assets and emission/compensation on-chain; GHG offsetting (lock/unlock)
- Users’ identification and transactions validation
- Data repository and management
- Data collection & modelling with a focus on LNG
- Energy-specific ontology & semantics for selective disclosure
- Data quality assessment

How these functionalities can be integrated within the software ecosystem:

Authoritative repository: granularity, massive amount of data from LNG supply-chain to improve upstream GHG emissions & further deployment of monitoring technologies.
Transparent, open smart contracts-based architecture for integration & interoperability with other software layers.
Reuse ontology & semantics for other energy supply-chain.

Gap being addressed:

Blockchain-based verification of Semantic Web data for selective disclosure
Harmonizing data collection, aggregation, validation, and reporting to build trustworthiness, transparency and efficiency in LNG suppliers claims about GHG emissions and compensations supporting climate goals for all supply chain LNG stakeholders.

Expected benefits achieved with the novel technology building blocks:

Clear delineation, collaborative approach (vs. silos), authoritative single source of information, data transparency, identified legitimate users, added-value generation; premium (attached/detached) in case of re-export, co-purchasing, borrowing and lending; and auditable emissions intensity.

Potential demonstration scenario:

Create a digital representation of LNG assets with relevant data. LNG importers validate exporters' claims (provenance of information); quantify, track, & report GHG emissions & offsets (carbon credits) for flexible management: divide, transfer, stack and transact with a Premium
Attribute benefits of auditable emission intensities to clients.



project outcomes

We empower natural gas ecosystem to drive carbon neutrality all over the value chain, from well to end user. A multi-actor model allows players to interact in real time with volume and intangible value getting a delineation of who pays what.

This experience has been truly enriching for us as it enabled us to develop innovative features and successfully implement a new tool called DKG, within our solution which holds great promise for our industry. I would like to express my sincere gratitude to our mentor, Mr. Klevis Chembi, whose unwavering support and valuable insights have been instrumental in guiding us throughout this journey. His mentorship has been precious, and we are grateful for the opportunities it has provided us to grow and improve our solution. We are excited to share our progress with stakeholders in the LNG industry, and we eagerly look forward to the next steps of this venture. The feedback we receive from industry professionals will play a crucial role in refining our solution and ensuring that it aligns perfectly with market needs and expectations. Collaboration and support have been at the core of our success in OTCnLNG during the NGI ONTOCHAIN program, and we are committed to continuing this spirit of collaboration as we advance toward our goals. Together with our partners, stakeholders, and mentors, we are confident that we can bring about meaningful change and innovation in the LNG market.
