Nordbex and Kalmar Energi to assess regional district heating cooperation

The letter of intent –

reflects a shared ambition to review the technical, financial, and climate-related conditions for integrating surplus heat as a complement to Kalmar Energi’s current and future district heating production. Kalmar Energi has previously highlighted that surplus heat can contribute to more stable costs, reduced investment needs, and improved resilience in the energy system.

For Nordbex, the collaboration is a practical example of the company’s approach: developing and privately financing renewable power projects with integrated CO₂ capture that connect to, and create value within, local and regional energy infrastructure.

“Our core is renewable power generation with integrated CO₂ capture. When surplus heat from the process can be recovered and used in existing systems, it shows how climate solutions can also strengthen regional energy supply,” says Niklas Lindvall, CEO of Nordbex Nybro.

The initiative

An important step in Nordbex’s work to demonstrate how climate impact, resource efficiency, and energy-system value can be integrated in real-world projects.

Combining renewable power generation with CO₂ capture and surplus heat recovery can help reduce emissions and aligns with Sweden’s national and regional climate goals. In a high-level scenario now under review, the surplus heat could correspond to heating roughly 13,000 homes in the region—illustrating the potential of using energy that would otherwise go unused.

“Our ambition is to build scalable industrial solutions where CO₂ capture goes hand in hand with local energy value. Working with Kalmar Energi shows how that model can work in practice and supports our long-term growth,” says Thomas Öström, founder and CEO of Nordbex.
