New Delhi: India's top oil and gas producer Oil and Natural Gas Corporation (ONGC) is seeking global technology partners to cut gas flaring and achieve zero methane emission by 2030 as part of its ambitious decarbonisation plan, its Chairman Arun Kumar Singh said on Monday.
ONGC has substantially cut gas flaring, burning of methane gas that is produced when oil is extracted from below surface and would look to bring it down to nil as part of its environmental commitments.
In a post on LinkedIn, Singh said India's role in the global energy landscape is progressively becoming pivotal, and is likely to account for 25 percent of global energy demand growth over the next two decades.
According to the International Energy Agency (IEA), India's share in global primary energy consumption is expected to rise to 9.8 percent by 2050.
"India's share in cumulative global green-house-gas (GHG) emissions has been only 4 percent, and current emission is 7 percent, despite its population share of 16-17 percent," he said. "As a responsible corporate citizen of the world, we are fully aware of our obligation towards the mother planet, which is shared by developing and developed world alike. Accordingly, our nation is chasing a paradigm shift in energy consumption, with a focus on cleaner, greener, and sustainable alternatives."
With increasing energy demand, the commitment to decarbonisation is stronger than ever.
"ONGC has made significant contributions in reducing gas flaring in our exploration and production (E&P) operations, aligning with our environmental commitments; we have consistently worked to bring it lower and lower, and we aim to bring avoidable flaring down to zero by 2030.
"Similarly, substantive reduction has been achieved in the area of methane emission, and we aim to bring it down to zero level by 2030," he said.
Singh said ONGC uses a lot of gas to generate electricity as well as meet compression and other process needs of an oil and gas field. By 2028, this gas is intended to be replaced with green power wheeled to installations as far as 160 km from the west coast. The gas thus freed will be sold to industries like fertiliser and power plants.
"We envisage to wheel green electricity to our Mumbai Offshore fields on the Arabian Sea, replacing natural gas, currently being used to drive power devices at process platforms," he said.
Companies around the globe have pledged to slash down methane emissions by 30 percent from 2020 levels by 2030. Methane, which is a more potent greenhouse gas than carbon dioxide, tends to leak into the atmosphere.
This is sometimes deliberate when companies flare the gas that comes alongside crude oil, due to lack of consumption markets. It also can leak undetected from drill sites, gas pipelines and other oil and gas equipment.
Controlling methane, which has been rising in atmospheric concentration for decades, is seen as one of the easiest and cheapest ways to make an immediate impact on global greenhouse gas emissions.
"Collaboration and innovation are the key here. Realising this need, we extend an invitation to all the innovators offering superior technology and are ahead on the learning curve relating to this goal of nil methane emission and zero avoidable flaring," he said.
He went on to ask technology innovators to write to ONGC on possible solutions to the flaring and methane emission problem.
Flaring, which used to be done in the past because of lack of customers for gas, has been reduced by almost 80 percent, he said.
Crude oil pumped out of ground can easily be transported in trucks but to take gas from remote well locations to industries requires pipelines.
Sometimes, the amount of gas coming out with oil is so low that laying a pipeline becomes uneconomical.
ONGC used to flare 14-15 million standard cubic metres per day, but this has now come down to around 2 percent.
Gas flaring reduction and zero methane emissions are part of ONGC's decarbonisation drive which will also see the company putting up 10 gigawatt of plants to generate electricity from solar and wind, and constructing a 1 million tonnes per annum green ammonia plant on the west coast.
ONGC is also looking at setting pump storage projects at river dams to meet electricity demand at night when solar power cannot be generated. It will also set up compressed biogas plants to convert agri waste into gas that can be used to generate electricity, make fertiliser or turned into CNG to run automobiles.
The company, which accounts for about two-thirds of India's oil production and about 58 per cent of gas, plans to invest Rs 2 lakh crore on clean energy projects to meet its 2038 net-zero carbon emissions goal.
High pressure gas valued at Rs 816.08 crore was flared in Mumbai High field, the mainstay fields of ONGC, during 2012-20, according to a CAG report released in December 2021.
During 2012-13 to 2019-20, a total of 1,227.343 million metric standard cubic metres of high pressure gas valued at Rs 1,021.08 crore was flared, according to the CAG report.
