Aalborg CSP Buys Unique PTES Technology from Arcon-Sunmark

Aalborg CSP, a Danish renewable and energy storage specialist, has acquired all rights and patents for the unique Pit Thermal Energy Storage (PTES) technology from Arcon-Sunmark A/S, a solar energy equipment supplier in the country.

Now, this patented unique PTES technology, including a unique lid design, will be continued by Aalborg CSP for its global deployment.

Further, this technology plays a vital role, in terms of developing a future-proof energy system, where energy storage is a key element in the infrastructure that will help ensure a green energy transition.

Commenting on the development, Svante Bundgaard, CEO at Aalborg CSP A/S, said that “over the past years, we have followed the development and optimization of the PTES technology for the purpose of establishing potential cooperation in relation to our integrated energy systems with both high and low-temperature thermal energy storages. The new solution looks very promising, keeping a focus on providing utility companies with the necessary reliability and operational stability for long-term infrastructure projects.”

Additionally, this technology has a significant opportunity and several projects between 200,000 and 1,000,000 m3 which had already been identified as a promising pipeline within the European countries, even though the technology is still not implemented in many countries, the company said in a statement.

However, with the new design concepts and a large-scale commercial project already implemented and under-going testing, the PTES technology will be a key element in the energy infrastructure development in the coming 10 years.

The company holds profound experience in designing and developing complex energy and storage systems both nationally as well as internationally.

Besides acquiring all right & patents for the technology, the company has also strengthened its integrated energy system and energy storage department by welcoming 2 experienced specialists from Arcon-Sunmark.

Aalborg said that both the specialists will continue to work on the PTES solution as well as the patented lid technology and will assist in ensuring the dissemination and implementation of both products.

While expecting rapid growth in international interest and possibilities within the energy storage technology in general and the PTES technology in particular, Svante Bundgaard, said that “we know that the key to the future lays in cost-effective and reliable energy storage solutions. We are pleased that we now get to implement a technology that can help to ensure the expansion of the energy infrastructure in relation to low-temperature energy storage and help to stabilize and creating balance within the energy system. There is no doubt that this solution will be an essential part of the energy system of the future throughout Europe.”

Meanwhile, Aalborg CSP has been focusing on energy storage for a long time. Since then, it has been working with high-temperature energy storage. In Europe, energy for heating and cooling of homes constitutes around 50 per cent of the total energy consumption.
