OUR PARTNER

SSAB is a global steel company and a leading producer on the global market for Advanced High-Strength Steels (AHSS) and Quenched & Tempered Steels (Q&T), strip, plate and tube products, as well as construction solutions. SSAB’s steels and services help to make end products lighter and increase their strength and lifespan. SSAB has been at the forefront of sustainability in many ways and plans to eliminate all CO₂ emissions by 2045.

THE OPPORTUNITY

Steel manufacturing is energy and resource intensive and has an impact on the environment globally and locally. An environmentally-friendly electricity production is a crucial step towards the Swedish steel industry’s goal of a more sustainable steel production. As a part of the goal of a fossil free Swedish steel industry in 2045, SSAB decided to adopt Climeon’s Heat Power solution on their site in Borlänge to convert waste heat from the reheating furnace and continuous annealing line into heat power and 100% clean electricity.

The plant is conveniently located along Dalälven, a river in Sweden between the mountains of Dalarna and the Baltic Sea, which allows for a cool year-round temperature and makes for an ideal cooling source.

OUR SOLUTION

Climeon has utilized waste heat from the reheating furnace and continuous annealing line to provided stable green electricity to support production equipment. The installed system dynamically adjusts operating point to waste heat load and seamlessly works with varying production load and seasonal variation. Heat output from Climeon is added to the district heating network.

The system was originally installed at SSAB's site in Borlänge in 2015. The system has the capacity to produce an annual output of 1300 MWh of clean electricity. The electricity produced is currently being used to power internal operations at the plant, resulting in significant utility savings for the company's Borlänge plant.
