WHY IT MATTERS

Store summer heat — use it in winter.

OUR IMPACT

We store excess solar heat when supply is high. We release it when demand increases. We enable stable heat with very high solar share. Track record established under the Aalborg CSP name – now continued by aalborg hc systems.

FAQ

What does aalborg hc systems deliver?

aalborg hc systems designs and delivers integrated heating and cooling systems in new and existing networks.

This includes:

  • large-scale heat pumps
  • thermal energy storage (TES and PTES)
  • integration of multiple heat sources

The focus is on complete system solutions, not standalone technologies.

Can you integrate into existing district heating plants?

Yes. Most projects involve integration into existing infrastructure. aalborg hc systems connects new technologies to:

  • existing networks
  • boilers and CHP units
  • available heat sources

The result is a coordinated system upgrade, not a replacement of existing assets.

Do you act as EPC contractor?

Yes. aalborg hc systems delivers projects on an EPC basis.

This covers:

  • engineering and system design
  • procurement and supplier coordination
  • construction and commissioning

The responsibility remains with one party from concept to operation.

Which heat sources can you integrate?

aalborg hc systems integrates multiple heat sources within one system, including:

  • wastewater
  • geothermal energy
  • ambient air
  • industrial excess heat

Solutions are designed as source-agnostic systems, optimised for local conditions.

What do you need to get started?

A project can start with a limited set of data:

  • heat demand profile (load curve)
  • supply and return temperatures

Based on this, aalborg hc systems defines a first system concept and integration approach.
