India's first green methanol plant to turn Kutch's most invasive weed into marine fuel

📌 Summary:

• India's first green methanol production plant is being set up in Kutch, Gujarat, using Prosopis juliflora — an invasive shrub ranked among the "top 100 invasive species in the world" — as feedstock

• About the invasive weed: Prosopis juliflora (known locally as gando baval in Kutch, vilayati keekar in north India, velikathan in Tamil) has invaded thousands of km² in Kutch's Banni grasslands, choking native grasses and devastating biodiversity

• Historical irony: The shrub was originally introduced by the British in the 1920s to "green" Delhi, and later by Gujarat forest dept in 1961 to halt the advancing Rann salt desert — it subsequently spread uncontrollably

• Innovation: Converting an ecological threat into economic value — green methanol produced from this weed can fuel ocean-going ships (marine fuel), helping India meet International Maritime Organization (IMO) decarbonisation targets

• Green methanol production process: Biomass (weed) → gasification → syngas (CO + H₂) → methanol synthesis; when biomass-sourced, this is "green" methanol vs. "grey" (fossil-based)

• Why marine fuel: Shipping sector responsible for ~2.5% of global GHG emissions; IMO has set targets for 50% emissions reduction by 2050; green methanol is a key alternative fuel

• Dual benefit: (1) Removes invasive species damaging Kutch ecosystems; (2) Produces zero-carbon fuel for global shipping — a classic circular economy model

🎯 UPSC Relevance: GS3 — ENVIRONEMENT AND BIODIVERSITY: Invasive species management, circular economy; GS3 — INDIAN ECONOMY: Green energy, renewable fuel innovation; GS2 — International (IMO decarbonisation)

📝 Prelims Facts:

• Prosopis juliflora: Mexican-origin invasive shrub; introduced to India in 1920s (British) and 1961 (Gujarat); listed among world's top 100 invasive species

• Banni Grasslands: unique grassland ecosystem in Kutch; home to pastoral Maldhari communities; severely degraded by Prosopis invasion

• IMO (International Maritime Organization): UN agency regulating global shipping; set 50% GHG reduction target for shipping by 2050 (from 2008 levels)

• Green methanol: produced from biomass or using renewable electricity (electrolysis); carbon-neutral marine fuel

🔑 Key Term: Green Methanol — Methanol produced from biomass or renewable hydrogen, with a near-zero carbon footprint; increasingly used as marine fuel to decarbonise the shipping sector under IMO targets.
