India's National Coal Gasification Mission aims to achieve 100 million tonnes (MT) of coal gasification capacity by 2030 to start with, transforming domestic coal into clean energy, fuels, and chemical feedstocks. Coal gasification plays a pivotal role in reducing import dependence, enhancing energy security, and enabling a low-carbon industrial transition through syngas-based production of methanol, ammonia, urea, DME, acetic acid and other critical chemicals. This mission focuses towards India becoming self reliant and self sufficient (Atma-Nirbhar Bharat) in low carbon hydrogen production with an aim towards –
- Minimizing Natural Gas Import
- Export of energy in the form of hydrogen-based molecules
- Minimizing subsidies on account of food security
- Amid this national push, our Hydrogen Enriched Catalytic Coal Gasification (HCC) technology – a US-patented pioneering process – delivers a next-generation pathway for clean coal utilization. Operating at moderate temperatures and pressures, HCC uses a proprietary catalyst to enhance hydrogen yield by ~15%, minimize tar formation, and improve overall carbon conversion efficiency. This breakthrough makes coal-to-chemicals and coal-to-hydrogen projects more efficient, modular, and environmentally sustainable – supporting India's 100 MT by 2030 gasification vision with indigenous, high-performance technology.
A proprietary catalyst enhances hydrogen yield by ~15% in the fixed-bed coal gasification process.
H₂ content rises from 40–45 vol% to ~46–52 vol%, improving the H₂/CO ratio (typically at 1.7–2.0 at temperature of 1050–1100°C) ideal for downstream synthesis.
Promotes water–gas shift and steam reforming, reducing CO, tar, and char, thus improving syngas quality and plant uptime.
Enables lower steam-to-oxygen ratio, better thermal balance, and potentially lower operating temperature/pressure.
Higher H₂ yield boosts methanol and derivative output per ton of coal; marginal catalyst cost is offset by higher efficiency and reduced downtime.
Delivers cleaner, hydrogen-rich syngas with better process sustainability and energy integration suited to Indian high-ash coal.

- Incorporating a proprietary catalyst boosting hydrogen yield by 15% into the fixed bed gasifier operating at 10 bar and 900–1100°C positively shifts syngas composition toward higher hydrogen content (~50 vol% H₂). This improves downstream synthesis efficiency, reduces operational issues from tar, and may allow optimized steam usage, leading to better overall process economics and sustainability under Indian coal conditions.
- The integrated plant's revenue increases annually, driven by 10–20% market price escalation, with methanol (~42%) and DMEA (~34%) dominating contributions; enhanced pricing of urea and acetic acid further strengthens cash flow and project viability.
