For remote mining operations, island communities, industrial plants, and utilities, reliable electricity is not a luxury. It is the foundation of operations and growth. Traditional large-scale coal gasification plants involve prohibitive costs, lengthy construction times of 18-24 months, and significant environmental impact. Meanwhile, intermittent renewables like solar and wind cannot always guarantee the 24/7 baseload power required for critical operations.

The Coalwatt® system is a compact coal gasification power generation platform engineered for the demands of the modern world. It transforms solid fuels, primarily coal but also biomass and waste, into clean combustible syngas to generate electricity efficiently and with lower emissions.

Our coal gasification system comes in two main designs to match your fuel type and requirements. All systems are designed as complete coal gasification power generation systems ready for rapid integration.

Ideal for anthracite coal or coke, offering high efficiency and operational simplicity.

Our most popular system, designed to handle a wide spectrum of low-grade coals and biomass—perfect for small scale coal power plants in resource-diverse regions.

Our modular coal gasification power generation system allows for limitless scaling. Configure your mini coal power plant or utility-scale installation from standardized modules.

A mid-sized mining operation in a remote location needed reliable off-grid power. Traditional diesel gensets were too expensive to operate.

An industrial park with unstable grid connection installed a coal gasification power plant for baseload power and peak shaving.

The Coalwatt system excels as the reliable backbone of a sophisticated hybrid microgrid, combining the best of coal gasification power generation with renewables.

Our Energy Management System (EMS) intelligently orchestrates power between coal gas gensets, solar PV, wind turbines, biomass gasifiers, and battery storage. When renewables are insufficient, the gasifiers provide instant, stable power. This results in >99% reliability with minimized diesel backup.

Provide critical grid stability and peak shaving. During monsoon seasons or prolonged cloud cover when solar output falters, the coal gasification power plant can ramp up seamlessly to fill the gap, preventing blackouts and maximizing the utilization of existing infrastructure.

Need: Grid stability, peak load management, and rapid capacity expansion without multi-year construction.

Our Solution: Modular coal gasification plants that can be installed in weeks to support or defer expensive grid upgrades. Ideal for small-scale coal power additions in regional grids.

Need: 24/7 reliable heat and power (CHP) in often remote, off-grid locations.

Our Solution: A resilient on-site captive power plant that can run on low-grade fuel, slashing energy costs by up to 25% and securing operations against grid failures.

Need: To monetize coal reserves or low-grade coal stockpiles beyond traditional sales channels.

Our Solution: Transform raw material into high-value exported electricity using transportable modular gasification units—essentially a coal to power value-added solution.

Need: To electrify remote regions, replace aging inefficient plants, and achieve UN Sustainable Development Goal 7 (Affordable & Clean Energy) quickly.

Our Solution: A fast-deployable, lower-emission alternative to traditional coal-fired power plants that fosters economic development without the multi-year wait of traditional infrastructure projects.

The coal gasification plant cost varies significantly based on capacity, configuration, and local requirements. As a guideline, our modular systems offer 30-50% lower capital expenditure than traditional plants of similar capacity. A 1MW system typically ranges between $1.2M-$1.8M fully installed, with larger systems achieving better economies of scale. Contact us for a detailed project quotation.

Traditional coal plants burn coal directly to produce steam for turbines. Compact coal gasification first converts coal to syngas in a controlled environment, which is then used to fuel efficient gas engines. This results in higher efficiency (especially at smaller scales), lower emissions, fuel flexibility, and the ability to deploy rapidly in modular containers. It's fundamentally different technology better suited for small scale coal power plants.

Yes. Our Double-Fire Gasifier systems are specifically designed for fuel flexibility. They can operate on 100% coal, 100% biomass (like wood chips, rice husks, or agricultural waste), or any blend of both. This allows operators to use the most economically available fuel in their region and switch as market conditions change.

Modular gasification systems offer three key advantages for off-grid coal power generation: 1) Speed - Deploy in days versus years; 2) Scalability - Add capacity as demand grows without over-investing initially; 3) Transportability - Containerized modules can be relocated if mining operations move or needs change. This reduces risk and improves ROI for remote projects.

While diesel gensets have lower upfront cost, Coalwatt systems provide 40-60% lower operating costs due to cheaper coal fuel. For operations running 24/7, the payback period is typically 2-3 years. Additionally, our systems offer greater fuel security (coal can be stockpiled) and lower emissions. For any remote operation expecting to run for more than 3-4 years, coal gasification power generation is economically superior.
