Performance-first
HaaS focuses on delivered steam and operating reliability, with metering and reporting built into the concept.
Hybrid steam decarbonisation for industrial users
Heating as a Service (HaaS)
SecuSolar is developing hybrid HaaS concepts for industrial process steam users where reliability matters. The core idea is to electrify the stable base demand with an electric boiler, while LPG, LNG, or biogas backup supports peaks, standby duty, or operational resilience.
Practical transition pathway:
this hybrid concept is not fully CO₂-free where fuel backup remains part of the operating boundary.
It is intended as a realistic decarbonisation pathway with clear metering, transparent assumptions,
and future flexibility where technically viable.
Core idea
What HaaS means in this concept
The customer needs reliable steam, measurable delivery, and a realistic route to lower emissions — not abstract technology claims.
Retrofit focus
Strong fit for HFO boiler sites where phased electrification, cleaner backup fuels, and modernization can improve the operating boundary.
Commercial structure
At this stage, SecuSolar is focusing on BOOT-style delivery and investor-backed project structures for HaaS opportunities.

How it works
Operating logic in plain language
- Electric steam generation is sized to cover a stable portion of the site’s base demand profile.
- Backup boilers remain available where process continuity cannot be compromised or peak demand exceeds the electrified base load.
- SCADA / EMS logic coordinates available electrical supply, boiler dispatch, metering, and reporting visibility.
- The result is a practical transition pathway: electrify what is predictable, keep reliability transparent, and measure the outcome properly.
Application fit
Good-fit sites
HaaS is typically strongest where the process case is practical, the reliability requirement is real, and the decarbonisation pathway needs to be phased rather than forced in one step.
Technical fit
- There is a stable base steam demand, while peak demand can be supported through the hybrid setup.
- The site currently relies on HFO boilers, creating a strong case for phased emissions reduction and modernization.
- Moving backup supply toward LPG / LNG, combined with electrified base-load steam, can provide a practical and measurable improvement pathway.
- Boiler modernization measures such as economizers and controls upgrades can further improve overall system efficiency.
- Process continuity is critical, so reliability, dispatch logic, and transparent operating boundaries matter.
Commercial fit
- The customer wants to reduce fossil fuel dependence without taking on full upfront CAPEX immediately.
- BOOT-style delivery or investor-backed structures are easier to evaluate than full self-funded replacement.
- Transparent reporting, measured delivery, and operational accountability matter.
- A phased transition pathway is more realistic than promising full decarbonisation from day one.
Boundary honesty
Emissions boundary and current limitation
This concept is not fully CO₂-free today where LPG or LNG backup remains part of the system boundary. That should be stated clearly.
The practical value is that stable base demand can move toward electrified steam generation now, while hybrid backup preserves reliability during peak periods, outages, or process-critical conditions.
Future pathway
Hydrogen-ready pathway
Where technically and commercially feasible, compatible backup systems may also be assessed for a future hydrogen-ready pathway on a site-specific basis.
This depends on equipment compatibility, burner design, safety requirements, and fuel infrastructure. At present, hydrogen supply availability remains the main practical limitation, so any future pathway would need to be discussed project by project.
Commercial structure
How projects may be structured
Depending on the customer profile and project structure, a HaaS project may be developed through BOOT-style delivery or investor-backed SPV structures, with defined metering, operating responsibilities, and performance transparency.
First-step assessment
What we would need to review a site
- Steam demand profile and operating hours
- Current boiler arrangement and backup philosophy
- Current fuel type and approximate consumption
- Available electrical supply and site constraints
- Tie-in boundaries, shutdown windows, and reliability requirements
- Any available utility and fuel data from the last 12 months
