1. Is the system operational?
Yes. Both 1 kW and 5 kW hydrogen cooking systems have been successfully tested at IIT Bombay for over six months under regular operating conditions.
2. What is the water requirement for the GH₂ Chulha (25 kW)? What water quality is needed?
The proposed 25 kW system requires approximately 25 litres of demineralized (DM) water per day. A DM water unit is integrated with the plant.
3. What is the cooling water requirement?
No separate cooling water is required.
4. What is the area requirement for the Hydrogen Generation and Solar Energy Units?
Hydrogen Cooking System Footprint
- Hydrogen Generation Unit: 2 m² (5 kW system) | 7 m² (25 kW system)
- Solar PV Array: 40 m² (5 kW system) | 200 m² (25 kW system)
5. Which units will be installed in-house?
We are deploying a 25 kW hydrogen cooking system designed to serve 2 × 100 meals per day (equivalent to daily consumption of ~25 households).
System components:
- 25 kW Alkaline Water Electrolyser
- 40 kWp Solar Photovoltaic System
This installation is targeted at industrial canteens and institutional kitchens, not for domestic use at present.
6. What are the safety aspects? How safe is it to operate?
Safety is ensured through multiple layers:
- Low stored energy — Only 1/50th of the energy of a typical domestic LPG cylinder.
- Outdoor hydrogen storage minimizes risk.
- Hydrogen’s low density allows rapid atmospheric dispersion, preventing accumulation.
- IoT-enabled safety and control system ensures continuous monitoring.
- Hydrogen leak detection and automatic emergency shutdown enhance reliability.
7. Can the unit be remotely turned off?
Yes. The IoT-based system allows remote monitoring and control, enabling instant shutdown if required.
8. Is any regulatory approval required?
Yes. Since hydrogen storage is involved, PESO (Petroleum and Explosives Safety Organisation) approval is mandatory.
9. What is the basis for the LPG saving of 7 kg/day?
The system supports cooking for 2 × 100 meals per day (~25 families).
One 14.2 kg LPG cylinder lasts for ~50 family-days; hence, the system effectively replaces about 7 kg of LPG per day.
10. What is the life of the GH₂ Chulha?
The expected lifespan is 20 years.
11. What is the CO₂ emission saving over its lifecycle?
Replacing 7 kg of LPG per day avoids 24 kg of CO₂ daily (~9 tons/year).
Over 20 years, this eliminates approximately 180 metric tons of CO₂, achieving zero-emission cooking.
12. Who certifies the system as Green & Sustainable?
We are in discussions with Bureau Veritas and other competent agencies for certification.
13. Do you offer financial support or have any institutional tie-ups?
We are engaging with sustainability funds and green finance institutions to facilitate deployment at scale.
14. Are there any central or state subsidies available?
Currently, no subsidy is available.
15. Is manpower required for operation?
The system is fully automated and requires no continuous manpower.
Routine cleaning of solar panels and periodic checks will be necessary.
16. What maintenance is required?
Minimal maintenance is needed:
- Regular solar panel cleaning
- Periodic inspection of electrolyser and sensors
Both major components are designed for 20-year service life.
17. Is there a Guarantee and Warranty?
- Guarantee: 3 years
- Warranty: 10 years
- AMC: Available from Year 4 for continued reliability.
18. Can existing burners be used? What’s special about the H₂ burner?
Our patented hydrogen burner is engineered for 100% hydrogen use with no flashback risk, ensuring safe and stable operation — unlike conventional LPG/PNG burners.
19. What happens during rainy days?
Production may reduce due to low solar input, which can be mitigated by increasing hydrogen storage capacity.
20. Can it run on LPG if H₂ generation fails?
The pure hydrogen burner cannot. However, we also offer a hybrid burner compatible with high-percentage hydrogen blends in LPG/PNG.
21. Will you provide H₂ in cylinders if the generation unit fails?
Hydrogen unit failure is highly unlikely; backup provisions can be discussed if required.
22. What is the PNG saving equivalent?
Approximately 12.5 SCM of PNG per day.
23. What is the capital cost of the 25 kW GH₂ Chulha system?
Estimated ₹80–100 lakhs (PoC level), depending on configuration, excluding piping, taxes, and transport.
Recurring costs mainly involve periodic electronic component maintenance (≈every 5 years).
24. What is the payback period and carbon benefit?
Payback depends on fuel replaced (LPG/PNG/biomass) and eligibility for carbon credits.
At commercial scale, costs are expected to reduce significantly.
We plan to assist users in carbon credit monetization post-certification.
25. How many daily hours of operation are expected?
Hydrogen is generated during daylight and used for ~2 hours of cooking daily.
26. Can the system use grid power?
Yes, optional grid integration is available at additional cost.
27. How many days of H₂ can be stored?
This depends on the selected storage capacity, which is customizable.
28. What is the commissioning timeline?
Approximately 4 months from order placement.
29. What are the payment milestones?
- 50% advance at order placement
- 50% before dispatch
30. Is accelerated depreciation applicable?
Yes, subject to company’s asset amortization policy.
31. What are the Standard Operating Procedures (SoP)?
A detailed SoP manual, including do’s and don’ts, will be provided with the system.
32. Can excess solar power be used elsewhere?
Yes. When not cooking, solar energy is used for hydrogen generation, ensuring full utilization.
33. What happens to the O₂ generated during electrolysis?
Currently vented, but it is of therapy-grade quality and may be repurposed in future applications.
34. What is the maximum temperature of the electrolyser?
Approximately 80 °C.
35. What is the temperature of the H₂ flame vs LPG flame?
Hydrogen flame temperature ranges from 400–500 °C, peaking near 700 °C.
36. How does hydrogen cooking reduce kitchen heat stress?
At 1 ft distance from the flame, LPG raises ambient temperature by ~9 °C, while H₂ cooking increases it by ~2 °C — a 7 °C reduction, enhancing kitchen comfort and safety.
