Distributed ledger technology, also known as blockchain, can potentially enable low-carbon transition and sustainability. Since it provides transparency, distributed ledger technology may reduce the cost and improve the efficiency in the operation of the energy systems. However, key challenges associated with blockchain systems include scalability, user privacy, governance, and the degree of decentralization. This project aims to understand how distributed ledger technology would work with a focus on renewable natural gas and differentiated fossil natural gas. The economic and environmental impact assessment will be performed to inform the decision-makers about this emerging technology in the context of British Columbia’s natural gas supply chain.
