Cellulosic ethanol is ethanol (ethyl alcohol) made from cellulose, a stringy fibre found in plants, as opposed to the seeds or fruit of the same plant.
It can be made from plants like grass, wood, algae, or other types of plants. The usage of it as a biofuel is frequently considered.
Cellulosic bioethanol fuel has the potential to have a lower carbon footprint than fossil fuels because some of the carbon dioxide that is released while burning it is countered by the carbon dioxide that plants absorb as they develop.
The appeal of cellulosic bioethanol is that it might displace ethanol produced from corn or sugarcane. The use of these plants for ethanol production could increase food prices because they are also used to make food products; cellulose-based sources, on the other hand, often do not compete with food because most plant components that are fibrous to humans are not edible.
The enormous diversity and quantity of cellulose sources grasses, trees, and algae are present in practically every ecosystem on Earth is another possible benefit.
It is conceivable to produce ethanol from even the parts of municipal solid refuse like paper.
Cellulosic bioethanol’s high production cost, which is more complicated and time-consuming than ethanol made from corn or sugarcane, is now its biggest drawback.
The Global Cellulosic Ethanol Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The Indian Oil project at Panipat, Haryana, the first 2G cellulosic ethanol biorefinery in the nation. This 100 KLPD Project uses Praj’s patented technology to treat rice straw as a feedstock for ethanol production.
Praj serves as IOCL’s technology licensor and EPCM consultant.30 million litres of ethanol are produced annually at this 100 KLPD 2G ethanol bio-refinery, which is situated on 35 acres and processes 200,000 tonnes of rice straw (a lignocellulosic feedstock).
Within 90 days, 2G ethanol will start to be produced commercially after the facility has been fully commissioned. The specialised chemical company Clariant revealed that its sunliquid production facility in Podari, Romania, had created the first batch of cellulosic ethanol for sale.
Shell, a top global oil firm, has a multi-year deal for the whole offtake. The factory conducted a thorough commissioning procedure during the previous six months, which led to a smooth commencement of production.
250,000 tonnes of agricultural leftovers sourced locally will be converted into about 50,000 tonnes of second-generation biofuels.
This plant’s cellulosic ethanol can be used as a drop-in replacement for other fuels and also has prospects for other downstream uses such as the production of bio-based chemicals and sustainable aviation fuel.
