Ethanol taking centerstage in India's clean energy landscape amid growth in biofuels
New Delhi: Ethanol, the renewable fuel made from plant materials, is fast gaining prominence in India's clean energy sector with its increasing use in replacing fossil resources as part of a larger movement favouring
biofuels
. Consider the fact that the average Ethanol Blending Percentage achieved by the Oil Marketing Companies (OMCs) reached 18.4 per cent at the end of March 2025, from 14.6 per cent in the previous year, inching closer to the national target of 20 per cent.
"As far as use of biofuels in the transport sector is concerned, ethanol blending has been a great success and we are now touching 20 per cent of ethanol bending in gasoline. There are discussions on ethanol blending beyond 20 per cent. There are talks about using flex fuel vehicles which are also coming up. All the OEMs have been given a target to come out with flex fuel vehicles in this year. With that ethanol blending percentage will go higher," said Alok Sharma, Director (R&D) at
Indian Oil Corp
.
The oil companies are also working on an
Alcohol to Jet (ATJ) fuel
plan. While these plants are in the initial stages they will also come up in the next 2-3 years as the blending percentage increases slowly. Thanks to the aviation boom and the upcoming CORSIA mandates oil firms are shifting focus to
Sustainable Aviation Fuel (SAF)
. IOC, for instance, is trying to use Used Cooking Oil (UCO) for making SAF, and the first plant is likely to be commissioned by October 2025 on Coprocessing route. IOC plans to produce at least up to 1-2 per cent of SAF blended ATF.
"By 2030, there is a likely mandate that 5 per cent of aviation fuel will be SAF. We are also trying to modify some of the plants where we can use UCO in our refineries. There are dedicated plants also being thought of where we can use UCO without co-processing to produce neat SAF. So, Ethanol is definitely going to be a centerstage going forward in the form of ethanol blending in gasoline, ethanol blending in diesel, and it will also be used as feed for producing aviation fuel," Sharma said.
Parallely, Indian Oil has set up its first plant for
2G Ethanol
-- produced from agricultural residues and non-food crops -- at Panipat even as it faces a few issues in handling of the feed. It is running the plant at around 50 per cent capacity while the scale up-related issues are sorted. Other OMCs are also setting up at least three more plants. The companies see 2G ethanol too playing a critical role in boosting clean energy uptake as the issues surrounding feed supply chain, feed handling and the high price of 2G ethanol are addressed.
Apart from Ethanol, the past few years have witnessed progress on
bio-CNG
front too, which is receiving push under the SATAT scheme. Indian Oil has already set up three CBG plants under SATAT and it has plans to set up around 30 plants this year. "The CBG programme has received a push also because of the CBG blending mandates -- 1 per cent by 2026, and increasing to 5 per cent by 2030. There are various schemes launched by the government on these initiatives including on Ethanol blending, biofuel policy, PM JI-VAN Yojana, Gobardhan etc. A lot of policies have been launched to push these fuels in the energy mix," Sharma said.
Another key promising area in fuel research is bio-Hydrogen used in the transport industry. IOC is working in this direction. Apart from Hydrogen production from the electrolysis of water, work on biomass gasification as a pathway is gaining traction. Indian Oil is trying to produce
green Hydrogen
via this route jointly with the Indian Institute of Science (IISc). The OMC has already developed a process allowing 5 kg per hour of Green Hydrogen to be produced from biomass gasification and it plans to scale it up in one of its refineries. The company also sees potential in using CBG reforming as a Green Hydrogen pathway.
Overall, the biofuel sector in India is grappling with five broad challenges including skills, standards, segregation of waste, scale up and supply chain but Sharma believes there are many opportunities too in areas like 2G Ethanol, WTE, and non-food crops. India is aiming to become Net Zero by 2070, and in the Oil & Gas sector most of the companies have already announced their Net Zero targets.
For example, IOC has plans to achieve operational Net Zero by 2046. Sharma believes in order to achieve the Net Zero goal, action is required on key areas like energy efficien cy, renewable energy including biofuels, Green Hydrogen, and Carbon Capture, Utilization and Storage (CCUS). The focus on biofuels must be ramped up specifically in view of their critical role in the decarbonisation of the automobile sector too.

Trade barriers, plane delivery delays challenge global airline growth
NEW DELHI -The head of a global airlines industry body said on Monday that growing trade barriers risked damaging the economy and the air travel sector, and "unacceptable" plane delivery delays were frustrating growth plans at a time of record passenger numbers. The International Air Transport Association shaved a key forecast for 2025 industry-wide profits, blaming trade tensions and declining consumer confidence. "Like all forms of connectivity, flying makes the world more prosperous," IATA Director General Willie Walsh said at the group's annual meeting in New Delhi. "That stands in contrast to isolationism, trade barriers and the fragmentation of the multilateral rules-based system. These destroy wealth and lower living standards. For the times we live in, this is an important message," he said. Sweeping tariffs imposed by U.S. President Donald Trump have stoked fears of an economic slowdown and squeezed discretionary spending, prompting many consumers especially in the United States to delay or scale back travel plans. They also threaten a decades-old pact between more than 30 countries to eliminate duties on aircraft and their parts. While Walsh said there was no indication aircraft prices had increased due to tariffs, he said airlines would resist any attempt by aerospace manufacturers to raise prices and called for governments to "keep aerospace out of trade wars". IATA represents some 300 airlines accounting for more than 80% of global traffic. On environmental sustainability, Walsh said progress was not what it should be at this point in time. He criticised energy firms for not producing enough sustainable aviation fuel , which is made from waste oil and biomass and costs more than conventional jet fuel. IATA has increasingly been warning that airlines will struggle to meet their sustainability goals, but Walsh said the aviation industry was still aiming for net-zero emissions by 2050 based mainly on a gradual switch to SAF. DELIVERY DELAYS More people are flying than ever before after a post-pandemic passenger market recovery, but airline growth is being hampered by extended plane delivery delays and supply chain bottlenecks driving up maintenance and repair time. Walsh called predictions of aircraft delivery delays throughout this decade "off-the-chart unacceptable". He said the airline industry was evaluating legal options over the delays, but it preferred to work with manufacturers collaboratively. "The manufacturing sector is failing badly," he said. IATA said the number of deliveries scheduled for 2025 was 26% less than what was promised a year ago, although at 1,692 this would be the highest number of new planes since 2018. "Further downward revisions are likely, given that supply chain issues are expected to persist in 2025 and possibly to the end of the decade," IATA said in the update to its industry outlook. Tim Clark, president of the world's largest international airline, Dubai's Emirates, said on Sunday that the pandemic was no longer an acceptable excuse for delivery delays and challenged planemakers to take responsibility. Similar frustration was voiced by Saudi budget carrier flyadeal. "Delays are becoming inexcusable. Transparency, to be frank, is lacking, and we're getting agitated. How else can we plan? I mean it is just going beyond a joke now," flyadeal CEO Steven Greenway told Reuters. U.S. planemaker Boeing is trying to stabilise and ramp up production after a quality crisis and a labour strike slowed output last year. Last week, sources told Reuters that Europe's Airbus has been warning airlines it faces another three years of delivery delays. Despite the challenges, carriers are still looking to purchase more planes to ensure they can meet future travel demand. Tata Group's Air India is in talks with Airbus and Boeing for a major new aircraft order including some 200 extra single-aisle planes, topping up a mammoth deal in 2023 as the former state carrier pursues a multi-billion-dollar revamp, Reuters reported on Sunday.

Key climate target of airline decarbonisation 'in peril': IATA
Live Events NEW DELHI: The airline industry's flagship goal of decarbonising by 2050 is now "in peril" due to climate-sceptic policies, including those of US President Donald Trump , the leading airline association IATA warned on emergence of leaders favouring fossil fuels and recent regulatory rollbacks are "obviously a setback... it does imperil success on the 2050 horizon", Marie Owens Thomsen , the International Air Transport Association's senior vice president for sustainability, told reporters."But I don't think it's going to halt or reverse progress. I think it will just slow progress," she said at the IATA annual industry conference in Republican administration is supporting the development of fossil fuels in contrast to his Democratic predecessor Joe Biden, who had massively supported the production of renewable aviation fuels through tax aviation agency members, from the International Civil Aviation Organisation (ICAO), have set the year 2050 as their goal for achieving net-zero carbon emissions for air travel -- an industry often criticised for its outsized role in climate air transportation industry has faced growing pressure to deal with its contribution to the climate responsible for 2.5 percent to three percent of global CO2 emissions, the sector's switch to renewable fuels is proving difficult, even if the aeronautics industry and energy companies have been seeking achieve net-zero emissions, airlines rely on non-fossil sources known as Sustainable Aviation Fuel (SAF).However, SAF biofuels are still three to four times more expensive than petroleum-based jet fuel."Another problem, which is related, is the fact that oil is so cheap," Owens Thomsen said. "I think that also diminishes the sense of urgency that people have."A barrel of Brent North Sea crude, the international benchmark, stands below $65 as a result of Trump's tariffs, his call to "drill baby drill" and especially a decision by OPEC+ to hike crude output represents an immediate boon for airlines, whose fuel costs represent between a quarter and a third of operating is seen as a crucial ingredient in hitting emissions targets. The biofuel produces lower carbon emissions than traditional jet fuel and is made from plant and animal materials such as cooking oil and Union rules require carriers to include two percent of SAF in their fuel mix starting this year, rising to six percent in 2030 before soaring to 70 percent from Thomsen estimated on Sunday that $4.7 trillion in investment is needed to establish SAF sectors capable of meeting the needs of air transport by 2050."It is entirely achievable," she said, adding that the raw materials and technology already exist and simply need to be developed."The money involved is very comparable to the money that was involved in creating the previous new energy markets, notably obviously wind and solar," she money could be found just by stopping subsidies to oil producers, she said."The world is subsidising large oil companies to the height of $1 trillion per year," she said."With that money, if it were redirected in its totality, we could solve our energy transition in less than five years."IATA also indicated on Sunday that it expects global SAF production to double this year compared with 2024 to 2.5 billion litres -- slightly down from its previous projections of 2.7 billion litres."This represents only 0.7 percent of total aviation needs," IATA Director General Willie Walsh said.

Indian Oil bets big on clean energy with 10,000-tonne Panipat plant
In a major stride toward clean energy transition, Indian Oil has finalised the Levelized Cost of Hydrogen (LCOH) for India's largest green hydrogen generation unit at its Panipat Refinery & Petrochemical Complex, the company said in a statement on Friday. Slated for commissioning by December 2027, the facility will produce 10,000 tonnes of green hydrogen annually — replacing fossil-fuel-based hydrogen currently used in refinery operations and significantly reducing carbon emissions. "This initiative is aligned with Prime Minister Narendra Modi's National Green Hydrogen Mission and forms a critical part of IndianOil's broader decarbonisation strategy ," the state-run oil major said. The project marks IndianOil's formal entry into the green hydrogen sector and is set to be the largest such initiative in the country to date. It is expected to play a pivotal role in helping the company meet its Net Zero targets. Indian Oil Chairman Arvinder Singh Sahney, speaking earlier this year at the World Economic Forum in Davos, said, 'The green hydrogen plant is now alive. We have got very good bids for it. And now the tenders are under evaluation. Within a month or so, we will be able to award the job, and within two years, that 10,000 tons per annum plant at Panipat will be commissioned.' The plant aims to boost India's green energy push and reinforce IndianOil's position at the forefront of the country's energy transformation journey.
