Why in news?
- India’s Reliance Industries Ltd has recently released developed cutting-edge algae-to-fuel technology.
About Algal biofuels:
- Algae came to the limelight in the world’s fight against climate change about a decade ago for its vast benefits in industrial production.
- It can synthesise large volumes of oil (20 times more than that of mustard per acre), grow fast (10 times quicker than terrestrial plants) and capture carbon dioxide (CO2).
- Since then, big industries and startups around the globe have been working to commercialise algae-based biofuel processes to reduce dependence on conventional fossil fuels like petrol and diesel.
- Microalgae are excellent at converting CO2 and sunlight into oil-rich biomass, especially when compared to land-based crop plants like oil palm and soy.
- By adapting microalgae to function as cell factories producing energy-dense oils that can easily be refined into renewable diesel and jet fuel, we can reduce greenhouse gas emissions by 70 per cent.
Add ons:
- At the global level, oil and gas giant ExxonMobil partnered with Viridos to commercialise algal biofuels.
