Well-integrated PTES systems enable efficient utilization of surplus energy from renewable sources and industry, as well as the delivery of stable and cost-effective heating and cooling on demand.

At Aalborg CSP, we offer turnkey delivery of customized pit thermal energy storage systems as well as supply and installation of PTES lid solutions.

How does it work?

A PTES is a large water reservoir used for storing thermal energy from e.g., solar heating- and biomass plants, industrial processes, wind turbines and PV-panels . The storage allows for the decoupling of consumption and production, enabling the optimization of heating and cooling production, while ensuring that both base and peak loads are met through the stable and flexible discharge of the storage.

Benefits

  • Storage of renewable and surplus energy
  • Cost-effective technology
  • Increased efficiency and flexibility
  • On-demand energy and peak load coverage
  • Scalable technology
  • Good integration possibilities
  • Can be used as both heating and cooling storage
  • Supports sector coupling and electrification

On-demand green energy with intelligent PTES integration

Integrated energy systems that utilize PTES systems in combination with renewable energy plants are a key component of future green energy systems. A PTES is ideal when combined with heat pumps and electric boilers, as well as solar thermal, PV, biomass, biogas, and power-to-x plants.

While the storage technology is often associated with seasonal storage, its profitability and value are much higher when used as hourly, daily, and weekly storage for peak shaving.

An integrated energy system consisting of a PTES combined with one or several renewable energy plants can supply e.g., district heating networks with on-demand energy. The storage creates a temporal connection between the heat supply and demand. The flexibility of the storage also enables the constant use of the most cost-effective heat source.
