Methanol economy is a future economy in which methanol and dimethyl ether replace fossil fuels as a source of energy storage, ground transportation fuel, and raw material for synthetic hydrocarbons and their products. The concept of "Methanol Economy" is aggressively promoted by China, Italy, Sweden, Israel, the United States, Australia, Japan, and many other European nations. Methanol, a clean-burning drop in fuel that can replace both petrol and diesel in transportation and LPG, Wood and Kerosene in cooking fuel, accounts for 10% of fuel in China's transportation sector. This article explains about the Methanol Economy which is important for UPSC IAS exam preparation.

Methanol Economy

• Methanol is a low-carbon, hydrogen-carrying fuel made from high-ash coal, agricultural waste, CO2 from thermal power plants, and natural gas. It is the greatest method for India to achieve its commitment to COP 21(Paris Agreement).
• The 'Methanol Economy' plan of the NITI Aayog aims to reduce India's oil import bill, greenhouse gas (GHG) emissions, and the conversion of coal reserves and municipal solid waste into methanol.
• The Methanol Economy will also generate over 5 million employment via methanol production/application and distribution services.
• Additionally, mixing 20% DME (Di-methyl Ether, a methanol derivative) with LPG can save Rs 6000 crore per year.
• This would save the consumer between Rs 50 and Rs 100 each cylinder.
• In Hyderabad, the first indigenously designed high ash coal gasification based methanol production plant was just opened.
• BHEL (Bharat Heavy Electricals Limited), a government-owned engineering business, has successfully demonstrated a plant for producing methanol from high-ash Indian coal.

Advantages of Methanol

• Methanol is a clean-burning liquid fuel that may be used in place of petrol and diesel in transportation, as well as LPG, wood and kerosene in cooking. It can also be used to replace diesel in railways, the marine sector, generators, and power generation, and methanol-based reformers might be an excellent complement to hybrid and electric vehicles.
• By using Methanol, India would be able to produce its own indigenous fuel at a cost of roughly Rs. 19 per litre, which is at least 30% less than any other accessible fuel.
• Methanol blending with petrol would cut our fuel expense by at least Rs. 5000 crore per year over the next three years.
• Methanol is not only a clean fuel, but it is also light and easy to transport to mountainous places. Adopting methanol would help to reduce the growing cost of fuel, particularly LPG.
• Methanol may be economically kept for an extended period of time and fetch a higher price on the commodities market.
• Methanol may be created from municipal garbage, which aids in the reduction of urban solid waste.

Methanol Economy - International Practices

• Methanol currently accounts for over 9% of China's transportation fuel. Millions of Methanol-powered automobiles have been converted.
• China alone generates 65% of global Methanol, and it does it using coal. Israel and Italy have implemented the Methanol 15% blending programme with petrol and are rapidly advancing towards M85 and M100.
• Methanol and DME are widely used in Japan and Korea, while Australia has embraced GEM fuels (Gasoline, Ethanol, and Methanol) and mixes about 56% Methanol.
• Methanol has become the preferred fuel in the marine industry globally, with nations such as Sweden in the forefront of adoption.

Environmental and Economic Impact of Methanol

• Blending 15% methanol with gasoline can result in a 15% reduction in gasoline/crude oil imports. Furthermore, this would reduce GHG emissions by 20% in terms of particulate matter, NOx, and SOx, improving urban air quality.
• In addition, the Methanol Economy will generate over 5 million employment through methanol production/application and distribution services.
• Additionally, mixing 20% DME (Di-methyl Ether, a methanol derivative) with LPG can save Rs 6000 crore per year. This would save the client between Rs 50 and Rs 100 each cylinder.
• Renewable methanol, which captures CO2 from the environment, is gaining popularity and is regarded as the "Enduring Energy Solution Known to Mankind." Methanol is a crucial answer to the world's burning problem of urban pollution.

Significance of Methanol based Economy

• The Methanol Economy is the "Bridge" to a complete "Hydrogen-based fuel systems" ambition.
• Methanol is a scalable and sustainable fuel that may be generated from a wide range of feedstocks, including natural gas, coal, biomass, municipal solid waste, and CO2.
• C02 from steel mills, thermal power plants, cement plants, and other sources may be used to make Methanol in huge numbers.
• Crude oil imports deplete our foreign exchange reserves, placing tremendous pressure on our currency and reducing our negotiating strength with the rest of the globe.
• Methanol has the potential to be a significant market in India, in addition to helping us cut our oil imports by 20%.
• Currently, India imports methanol from Saudi Arabia and Iran.
• The development of methanol-based technologies might transform India from an energy-importing to an energy-exporting economy.
• The Methanol Economy can be one of the most effective strategies to alleviate the environmental risks associated with a developing economy.

Methanol Economy Programme - NITI AAYOG

• India has a Methanol production capability of 2 MT per year. According to the NITI Aayog plan, Indian High Ash coal, Stranded gas and Biomass can create 20 MT of methanol per year by 2025.
• With 125 billion tonnes of confirmed coal reserves, 500 million tonnes of biomass created each year, and vast volumes of stranded and flared gases, India has enormous potential for guaranteeing energy security through alternative feedstock and fuels.
• NITI Aayog has devised a strategy to replace 10% of crude imports with Methanol alone by 2030.
• This takes about 30 MT of Methanol. Methanol and DME are significantly less expensive than petrol and diesel, and India may expect to lower its fuel expense by 30% by 2030.
• Production of methanol in large quantities from Indian high ash coal using indigenous technology and employing regional production techniques to generate methanol in large quantities for Rs. 19 per litre.
• India will deploy C02 capture technology to make coal use completely environmentally benign, as part of our COP21 pledges.
• Stranded gas from biomass is used to produce methanol. These feed supplies have the potential to account for over 40% of Methanol production.
• Methanol and DME are used in transportation, including rail, road, marine, and defence. Other uses include industrial boilers, diesel generators, power generating, and mobile towers.
• Cook stoves that use methanol and DME as a home cooking fuel. Blending of LPG with DME.
• Methanol use in marine, generator, and transportation fuel cell applications.

Other Government Initiatives

• The Bureau of Indian Standards has approved 20% DME blending with LPG, and the Ministry of Road, Transport, and Highways has approved M-15, M-85, and M-100 mixes.
• In a joint venture with Israel, five methanol facilities based on high ash coal, five DME plants, and one natural gas-based methanol production facility with a capacity of 20 MMT/annum are proposed.
• Cochin Shipyard Limited is building three boats and seven cargo vessels for the Inland Waterways Authority of India to utilise methanol as a marine fuel.

Way Forward

• With 125 billion tonnes of confirmed coal reserves and 500 million tonnes of biomass created each year, India has enormous potential for guaranteeing energy security through alternative feedstock and fuels.
• Methanol, on the other hand, does not receive the same level of government attention as EV (Electric Vehicles), despite the fact that the former can arrive quicker. There is a lot of work to be done to fully establish the Methanol Economy.
• The development of methanol-based technologies has the potential to transform India from an energy importer to an energy exporter.

Conclusion

Methanol is a scalable and sustainable fuel that may be made from a range of feedstocks, including natural gas, coal (Indian High Ash Coal), biomass, municipal solid waste, and, most crucially, CO2. The Government of India's policy think tank, NITI Aayog, is launching an initiative named 'Methanol Economy' to encourage the use of methanol in different industrial operations. The Methanol Economy is the most effective strategy to manage the environmental risks associated with a rising economy. NITI Aayog is a crucial driver in developing a road plan for full-scale implementation in the near future.
