India's largest oil company IOC would build the nation's first 'green hydrogen' plant at its Mathura refinery, as it aims to prepare for a future catering to the growing demand for both oil and cleaner forms of energy.
Indian Oil Corporation (IOC) has drawn a strategic growth path that intends to maintain focus on its core refining and fuel marketing businesses while making bigger inroads into petrochemicals, hydrogen and electric mobility over the next 10 years, its chairman Shrikant Madhav Vaidya said.
The company would not set captive power plants at all its future refinery and petrochemical expansion projects and instead use the 250 MW of electricity it produces from renewable sources like solar power, he articulated in an interview.
"We have a wind power project in Rajasthan. We intend to wheel that power to our Mathura refinery and use that electricity to produce absolutely green hydrogen through electrolysis," he stated.
This would be the nation's first green hydrogen unit. Previously, projects have been announced to produce 'grey hydrogen' using fossil fuels such as natural gas.
Hydrogen is the latest buzz for meeting the world's energy requirements. Hydrogen, in itself, is a clean fuel but manufacturing it is energy-intensive and contains carbon by products.
Brown hydrogen is created through coal gasification while the procedure of producing grey hydrogen throws off carbon waste. Blue hydrogen uses carbon capture and storage for the greenhouse gases produced in the production of grey hydrogen.
Green hydrogen production - the eventual clean hydrogen resource - uses renewable energy to create hydrogen fuel.
"Mathura has been selected by virtue of its proximity to TTZ (Taj Trapezium Zone)," Vaidya
stated adding the green hydrogen would replace carbon-emitting fuels that are used in the refinery to process crude oil into value-added products such as petrol and diesel.
He said all of the expansion projects would use grid electricity, preferably green power to meet the energy requirements.
"We have got a number of expansions down the line which are already approved. We will not have a captive power plant and will utilise power from the grid, preferably green power. This will help decarbonise some part of the manufacturing," he stated.
IOC's refinery expansion plans comprise raising the capacity of units at Panipat in Haryana and Barauni in Bihar and setting up a new unit near Chennai.
"We are going to add 25 million tonnes of our refining capacity by the year 2023-24. We are 80.5 million tonnes now including CPCL, we are going to be 105 million tonnes," he added.
Vaidya said IOC was pushing ahead with research on carbon capture, utilisation and storage technologies -- space where it is looking for global collaboration to meet its Paris climate goals.
Hydrogen, he articulated, would be a fuel of the future. IOC is planning to build several hydrogen production units on a pilot basis.
It includes a project at Gujarat refinery to produce finite purity hydrogen of 99.9999 per cent for hydrogen fuel cell buses. "Today, 50 buses in Delhi are being fueled by hydrogen-spiked compressed natural gas, or H-CNG, which has 18 per cent hydrogen content," he commented adding hydrogen fuel cell buses would be put to service on iconic routes of Vadodara-Sabarmati and Vadodara-Statue of Unity, Kevedia.
"About 15 fuel-cell-powered buses, with the fuel cells entirely India-made, are expected to ply in the second half of 2021. Since running these buses would require hydrogen, IOC is setting up a plant, whose capacity could be anywhere between 200 tonnes and 400 tonnes per day," he further said.
Petroleum refining and marketing would continue to be IOC's core businesses with much higher petrochemicals integration. Also, gas would play a larger role and the company would have a presence in electric mobility space through charging stations at petrol pumps and a planned battery manufacturing unit.
Forecasts by various agencies see Indian fuel requirement climbing to 400-450 million tonnes by 2040 as against 250 million tonnes now. It gives enough legroom for all forms of energy to co-exist, he said adding the demand augmentation makes it imperative to pursue refining expansion as well as expand footprint in compressed natural gas, LNG, biodiesel and ethanol.
Vaidya said IOC had already commissioned battery transaction stations across many cities. The company already has installed 286 charging stations, including swapping stations, across the country, which would be raised to 3,000 EV charging stations in the next few years.
