Green methanol project using Prosopis juliflora for clean fuel

Context: Green methanol

India plans to convert Prosopis juliflora, among the world’s top 100 invasive species, into green methanol for marine fuel, linking ecological control with clean energy.

Species in News – Prosopis juliflora

  • Origin: Mexico
  • Local names: Gando Baval, Vilayati Keekar, Seemai Karuvelam
  • Status: Among top 100 invasive species globally
  • Introduced: Colonial period for afforestation

Issues

  • Highly invasive and fast spreading
  • Replaces native grasses in Banni grassland
  • Threat to biodiversity in Kutch

Utility

Dense hardwood, high calorific value → suitable biomass feedstock

Green Methanol and Environmental Significance

  • Green methanol: Produced from biomass/renewable sources
  • Use: Alternative to bunker fuel in shipping

Environmental benefits

CO₂ ↓ up to 95% | NOx ↓ up to 80% | eliminates SOx and particulate matter | supports IMO norms

Process

Gasification → biomass to syngas (H₂ + CO)
Conversion → syngas to methanol

Banni Grassland

  • Location: Rann of Kachchh, Gujarat
  • Asia’s largest tropical grassland
  • Threat: invasion by Prosopis juliflora

Community

Maldharis pastoralists depend on it

Implications

  • Converts invasive species into economic resource
  • Supports clean shipping and energy transition
  • Reduces oil import dependence
  • Helps restore native grassland ecosystem

About the UPSC Civil Services Examination (UPSC CSE)

The UPSC Civil Services Examination (CSE) is one of the most competitive and esteemed examinations in India, conducted by the Union Public Service Commission to recruit officers for services such as the Indian Administrative Service (IAS), Indian Police Service (IPS), Indian Foreign Service (IFS), and others. The exam comprises three stages — Prelims, Mains, and the Personality Test (Interview) — designed to test a candidate’s knowledge, aptitude, decision-making, and leadership skills.


How to Prepare Effectively for UPSC CSE

Cracking the UPSC CSE requires a deep understanding of the syllabus, consistent revision, structured answer writing, and smart test-taking strategies.
