Green Energy for Business: Fuel-Switching Steam Without Disruption
Green energy for business is no longer a slogan, it’s a strategic lever for cost control, compliance, and growth. By switching to low-carbon steam without halting production, factories can cut fuel costs, meet QCVN standards, and accelerate their journey toward Net Zero, all while keeping throughput stable and predictable.
Why Low-Carbon Steam Now: Cost, Risk & Compliance
In manufacturing, steam systems drive over 70% of total energy use. For factories under Net Zero pressure, the fastest win is not electrification, it’s decarbonizing process heat.
Industrial leaders are now switching to low-carbon steam because the benefits are both financial and regulatory.
- Energy cost volatility: Fossil fuel prices have surged up to 200% since 2021. Biomass and hybrid fuels, meanwhile, have shown stable long-term pricing.
- Regulatory compliance: Vietnam’s QCVN 19:2024/BTNMT and upcoming carbon reporting mandates under the GHG Protocol require measurable CO₂e reduction.
- Customer & export demand: Global buyers now require emission transparency in supplier audits.
By transitioning your boiler fuel mix, you’re not just cutting carbon, you’re stabilizing your bottom line and future-proofing exports.

Technology Paths for Low-Carbon Steam
Every factory’s thermal system is unique. The optimal path depends on your fuel access, production stability, and emission goals.
Biomass Boiler Solutions (CFB, Chain Grate, Fixed Grate)
Biomass remains the most proven green energy for business option — reliable, scalable, and already compatible with local supply chains.
- CFB (Circulating Fluidized Bed): Handles variable moisture; up to 87±2% efficiency, suitable for paper, packaging, and textiles.
- Chain Grate: Ideal for pellets or wood chips; stable steam output and simpler maintenance.
- Fixed Grate: Compact solution for smaller factories or those using agricultural residues.
Thermal Oil Heater + Steam Generator
A hybrid system that produces both high-temperature oil (up to 400°C) and saturated steam from a single furnace. It minimizes equipment duplication and enhances energy recovery for food or textile applications.
HRSG / Waste Heat to Steam
Factories with turbines, incinerators, or kilns can reclaim waste heat to generate low-carbon steam. This solution boosts total efficiency and reduces primary fuel use.
Emission Control & Digital Layer
Modern low-carbon boiler solutions integrate bag filters, cyclones, and scrubbers, keeping stack dust <30 mg/Nm³ — compliant with QCVN 19:2024.
Paired with SCADA + ISO 50001 EMS, plants can continuously monitor, log, and verify emission data for ESG audits.

Throughput First: Designing for Zero Disruption
Switching fuels often raises one fear: downtime. For continuous manufacturing — food, paper, textiles — stopping production isn’t an option.
Redundancy & Backup Design
A resilient system means always having an “N+1” configuration: one backup boiler ensures stable steam when a unit is tied in or serviced.
Temporary steam supply (via mobile units) can also maintain throughput during transition periods.
Smart Cut-over & Commissioning
Pre-fabrication and modular skids minimize on-site work. Instead of dismantling the old system, the new boiler is connected in parallel and tested live.
This parallel run mode ensures uninterrupted production while gradually transferring the load to the new biomass unit.

Cost & Carbon: The Executive View (TOTEX Framework)
C-level leaders know that energy decisions are never just CAPEX — they’re TOTEX: total cost across design, fuel, O&M, and compliance.
Fuel Scenarios & Steam Cost Analysis
Steam cost (VND/ton) depends on delivered fuel price, boiler efficiency, and load factor.
- Biomass typically achieves 20–40% savings versus LPG or FO.
- Sensitivity testing with ±15% fuel price variance and ±5% load change helps confirm ROI robustness.
CAPEX–OPEX–Payback Model
A full-scale biomass system (20–40 TPH) may have a payback of 18–36 months, depending on scale and fuel logistics.
Add ISO 50001 energy management to continuously cut OPEX through real-time SCADA optimization.

Compliance & Reporting for Net-Zero Factories
Clean energy investments mean little without verifiable compliance. That’s why leading factories integrate environmental monitoring and data transparency from day one.
QCVN 19:2024 & 30:2012 Compliance
Vietnam’s emission standards define strict thresholds for dust, CO, NOx, and SOx.
Naan’s systems automate sampling frequency, data logging, and lab reporting, ensuring readiness for third-party and government audits.
GHG Protocol Alignment
Scope 1 (fuel-based) emissions are continuously tracked from boiler SCADA data.
Metrics like “kg CO₂e per ton steam” and “kWh per ton steam” form part of your ISO 50001 KPI dashboard, enabling transparent ESG reporting.

FAQ: Green Energy & Industrial Steam Systems
What are the financial benefits of switching to biomass or low-carbon steam?
Factories typically save 15–30% in total steam cost vs LPG or FO-fired systems. These savings depend on fuel availability, system efficiency, and continuous operation.
How long does it take to switch fuels?
Implementation averages 8–12 weeks — from design to commissioning. Naan’s skid-mounted systems and pre-tested modules reduce downtime by half.
How to ensure emission compliance?
All solutions meet QCVN 19:2024/BTNMT and QCVN 30:2012/BTNMT, verified through automated SCADA and certified stack testing.
What if we need both heat and power?
Naan’s co-generation systems deliver both saturated steam and electricity, improving energy utilization and lowering total emissions.
Does Naan offer operation and maintenance services?
Yes. Through its subsidiaries, Naan operates a Steam-as-a-Service model — clients only pay for steam output, while Naan handles operation, fuel, and compliance.
