PNGRB approves guidelines for CBG injection in gas pipeline, CGD networks

New guidelines for CBG injection into pipelines and CGD networks aim to improve project viability, ensure safe integration and accelerate green fuel scale-up

The Petroleum and Natural Gas Regulatory Board (PNGRB) on Wednesday approved new guidelines for injection of compressed biogas (CBG) into natural gas pipeline (NGPL) and city gas distribution (CGD) networks, providing a comprehensive framework for safe, efficient and standardised integration of the green fuel.

 

The approved guidelines define the quality and specification of CBG, installation procedures for CBG injection facilities, safety requirements such as odorisation and control systems, among other specifications. The guidelines will facilitate stakeholders in developing infrastructure, including project developers, CGD entities, technology providers and investors, the downstream regulator said.

 

The move would significantly improve project viability through assured market access, facilitate financing and infrastructure planning, and accelerate scale-up of CBG production across the country.

 

“The integration of CBG into the natural gas grid is expected to enhance the availability of domestically produced green gas, reduce dependence on imported LNG, improve energy security, and support India’s climate and carbon reduction goals,” said PNGRB.

 

Pipeline-based evacuation of CBG will facilitate higher utilisation of agricultural residue, cattle dung, municipal solid waste and other organic feedstocks, it added.

 

PNGRB said the guidelines have been developed through an extensive and inclusive consultative process. A technical committee comprising representatives from CBG producers, CGD entities and NGPL pipeline operators was constituted to address the technical, operational and safety aspects specific to CBG injection.
