Reducing GHG leakages within the Gas distribution network in Bangladesh

Greenhouse Gas Reduction through the CDM project

Some parts of the TITAS gas network are more than 50 years old with possibility of substantial leakage through the system. A systematic survey to detect leaks and repair of faulty joints is being undertaken to achieve the twin goals of reducing wastage of valuable gas and methane emission to the atmosphere which is twenty-five times more potent a greenhouse gas (GHG) compared with carbon di-oxide (CO2).

  • The GHG leakage detection and arrest of Methane from domestic and industrial systems is an ongoing project for PSL
  • The client is N/E climate out of Denmark, along with local assistance from the Bangladesh Gas distributors. 
  • This project is expected to save 28 MMCFD gas over a span of 5 years

Implementation of this project is expected to reduce emissions by more than 4 million tons of CO2 equivalent (tCO2e) GHG per year, generating around 40 million tCO2e Certified Emission Reductions (CER) over the next 10 years to be sold on CDM market and profit shared between TGTDCL and NE Climate A/S

PSL is now working as the local counterpart of NE Climate A/S for a CDM project UNFCCC#10077. The PSL team of around 90 technicians are identifying, quantifying and arresting fugitive methane gas from the household and commercial risers of natural gas distribution lines of the government owned Titas Gas Transmission and Distribution Co. Ltd. During the 1 year of baseline study, we have identified total gas leakage in excess of 387757 lpm (litres per minute) and arrested nearly 100% of that. Now, with 24 teams and 12 “High Flow Samplers (HFS)” we hope to prevent leakage of 19.72 MMCFD of gas which is about 1.5% of the gas off take of TGTDCL for non-bulk consumers. This is equivalent to saving nearly 3.8 million tons of CO2 per year going into the atmosphere and is capable of generating about 98 MW of power. PSL has surveyed approximately 6 lakh risers in the franchise areas of the company by end of January 2018. PSL has begun the monitoring phase of this project. During monitoring phase, PSL will recheck the riser’s leaky facilities and will ensure no leak exist. This project will run for 4 years up to 2022
