gas companies have grown their super-profitable CNG sales volume at a faster rate in the past two years than the less profitable segment of gas supplies meant for homes. City gas distributors sold 19.4 million metric standard cubic meters a day (mmscmd) of CNG in six months to March 2023, up 51% from October 2020 to March 2021 period, oil ministry data showed.
