Aalborg CSP and NEST develop new cost-effective thermal energy storage system

Share Article

The two companies have joined forces to develop a new direct-steam-to/from-concrete storage system. It will enable predictable and on-demand power generation with low operation and maintenance expenses.

The direct-steam storage concept (patent pending) is based on NEST’s patented thermal energy storage technology, Heatcrete®, in combination with Aalborg CSP’s steam generator design. The latter’s natural circulation system has proven a superior performance in some of the world’s leading CSP plants.

The direct-steam storage concept is a novel configuration of thermal energy storage and steam generation. It ensures on-demand power production during peak hours, when there is limited or no energy generation from the sun or other fluctuating renewable energy sources.

The direct-steam storage technology is easy to install in CSP plants and has a power generation capacity of up to 24 hours. It enables the delivery of electricity at peak times while increasing overall plant revenue in a substantial way.

The direct-steam storage concept is cost-effective compared to conventional molten-salt-based energy storage systems. The safe and durable solid-state storage medium, combined with the natural circulating steam generator with no need for any electrical heat tracing, guarantees low parasitic load. It also reduces operation and maintenance costs while increasing plant availability.

The operational and investment cost benefits, in addition to the flexible scalability of the system, makes it well suited for off-grid, co-generation and micro-grid applications as well. In these cases, plant availability and energy supply security are of outmost importance. Moreover, the modular storage elements are made from readily available raw materials that can typically be sourced locally.

The energy storage technology can be easily customized to fit project specific requirements, including power generation, seawater desalination, process steam and district heating/cooling. “The cooperation between Aalborg CSP and NEST expands the horizon for the CSP market as increased performance will lower the levelized cost of energy (LCOE) of CSP power plants, resulting in global technology competitiveness” - said Svante Bundgaard, CEO of Aalborg CSP.

“The direct-steam technology will allow our companies to deliver much needed energy storage solutions for CSP projects and also to industrial plants with process steam requirements. The cooperation is expanding the existing market for our energy storage solutions designed for parabolic trough plants using thermal oil” – said Jarl Pedersen, Vice President Marketing & Sales at NEST.
