CST EnviroTech – Closed-Loop Hydrogen Based Steam Generator System (WTS-II)
CST EnviroTech’s closed-loop hydrogen steam generator system is a breakthrough in clean industrial energy, converting water into hydrogen fuel and high-pressure steam without fossil fuels or external water consumption. A hydrogen-powered IC engine drives an alternator that supplies 100% of the running electrical load and powers an alkaline electrolyser to continuously generate hydrogen and oxygen.

GENERATING Steam using Bio Mass - RAW WATER as fuel
CST EnviroTech’s WTS-VI Biomass–Hydrogen Integrated Steam (WTS-VI)
Generation System is a hybrid clean-energy platform designed to deliver reliable industrial steam while strengthening energy security, supporting decarbonization, and enabling practical energy-transition pathways.
In this configuration, biomass briquettes are converted in a gasifier to produce combustible producer gas. The gas then passes through a tar separation and collection system to ensure clean fuel quality before entering the IC engine–alternator set. The engine generates electrical power while releasing high-temperature exhaust gases at approximately 550 °C.
This thermal energy is captured in a Heat Recovery Unit (HRU). Cold feedwater entering the HRU absorbs the recovered heat and is converted into steam, which is supplied continuously for industrial applications such as process heating, sterilization, utilities, and other thermal demands.
All of the electrical power produced by the genset is utilized to operate the alkaline electrolyser and associated auxiliaries for hydrogen generation. The hydrogen is then blended back into the engine fuel, enhancing combustion characteristics, improving flame stability, and supporting lower-carbon and more efficient operation. Oxygen from electrolysis is safely vented or can be recovered for secondary industrial uses.
By combining hydrogen enrichment with biomass-derived producer gas, the system significantly improves the usable energy extracted from each kilogram of briquette. This leads to substantial fuel savings, reduced operating cost, and makes the overall plant highly economical and commercially workable for continuous industrial duty.
The overall configuration forms an intelligent, resource-efficient loop where:
✔ biomass provides primary renewable energy
✔ engine power drives hydrogen production
✔ hydrogen upgrades fuel quality
✔ exhaust heat generates steam
✔ tar and by-products are separated for safe management
The result is maximum utilization of every energy stream with minimal waste.
By integrating biomass gasification, hydrogen generation, engine power production, and waste-heat recovery, the WTS-VI delivers a resilient, low-emission, and future-ready steam solution for industries seeking fuel flexibility, long-term cost stability, and alignment with sustainability and climate commitments.
CST EnviroTech’s Biomass-Gas Generation Platform
CST EnviroTech’s Biomass-Gas Generation Platform is an integrated renewable energy solution that converts solid biomass into clean, usable gaseous fuel for heat and power applications. The system is engineered for reliable industrial operation, high resource efficiency, and responsible environmental performance.
In this process, biomass feedstock enters the gasifier together with controlled quantities of gasification agents such as air and/or steam. Inside the reactor, thermochemical conversion takes place at high temperature, transforming solid fuel into combustible producer gas while separating mineral residue as ash.
The raw gas then flows through a structured treatment line. First, it enters the gas cooling stage, where temperature is reduced and sensible heat can be recovered for secondary uses. During cooling, moisture condenses and is removed from the system. The gas subsequently passes through gas cleaning, where tar, particulates, and remaining contaminants are captured to ensure stable and safe downstream utilization. Collected tar and condensates are routed for controlled disposal or potential commercial recovery, while ash from the gasifier is separately discharged.
A centralized PLC-based control architecture continuously monitors temperatures, pressures, flows, and safety interlocks, ensuring optimized conversion efficiency and dependable 24×7 plant operation.
After conditioning, the clean producer gas is directed to the utilization block, where it can be flexibly deployed according to site demand:
✔ combusted in a gas-fired boiler to supply process or district heat
✔ used in a gas engine–generator to produce electrical power for local consumption or grid export
✔ safely diverted to a flare system during start-up or abnormal conditions
Exhaust gases are discharged through a controlled chimney system compliant with environmental norms.
By integrating fuel conversion, gas conditioning, and multi-path energy utilization, CST EnviroTech’s platform ensures that energy derived from biomass is fully optimized. The approach supports lower fossil-fuel dependence, improved waste management, and the creation of valuable by-products while maintaining strong operational economics.
The result is a modular, scalable, and future-ready renewable energy infrastructure suited for industrial campuses, municipalities, agro-processing clusters, and decentralized power generation.
