In Karlshamn, a collaboration between several organisations has created a sustainable, intelligent district heating system. The system is controlled using the latest AI technology and is constantly evolving to create a future-proof sustainable energy supply.

Haraholmen is an industrial park that brings together many sustainable initiatives and solutions to increase their positive impact. The site uses renewable energy, welcomes companies with a focus on environmental sustainability and is a hub for resource-efficient transport with access to roads, railways and a deepwater port.

MAX IV is a world-leading accelerator physics laboratory for research into synchrotron radiation. It is also unique in its ambitious sustainability aims. Its smart solutions in energy efficiency, biological diversity and waste management make it the first building to receive the BREEAM-SE environmental classification.

In central Stockholm, you find one of Europe’s largest district heating and cooling systems. Close to 90% of the city’s buildings are connected to the district heating network, which uses several innovative energy sources, such as excess heat and wastewater.

Luleå Airport is one of two pilot sites testing a new way to heavily reduce the carbon emissions. By using the district heating and cooling system for parked aircrafts, the airport’s electricity demand has dropped by 95 %.

The City of Gothenburg in Sweden uses a district cooling system powered by the cool flows from Göta älv.

The new district of Brunnshög in the city of Lund will be home to the world’s largest LTDH network (low-temperature district heating). The heating network is based almost entirely on fossil-free surplus heat recovered from MAX IV, another of Lund’s many innovative facilities.

The Fossil-Free Energy District (FED) in Johanneberg Science Park in Gothenburg is a unique project that demonstrates how to create a local digital marketplace for electricity, heating and cooling and help reduce the use of fossil energy.

Some 90 percent of Gothenburg’s apartment buildings are connected to the district heating network, a well-proven solution with a number of environmental benefits. But the district heating system has now been further improved using new technology to enable storage of heat for fluctuating needs.

Hörneborgsverket, a biofuel-based cogeneration plant, is at the heart of Övik Energi’s energy production. Hörneborgsverket produces roughly equal amounts of district heating, steam, and electricity. Some 99% of the fuels used at the plant are renewable, and the steam is distributed to local industries.

The generation of both district heating and electricity almost entirely from waste makes the Dåva CHP (combined heat and power) plant extremely energy efficient and environmentally sustainable. Its renewable sources include sorted waste and forest industry residues.

The small island of Händelö, which is part of the City of Norrköping in eastern Sweden, is home to a remarkable industrial symbiosis in which by-products from one company are used as input for neighbouring companies Everything at the site is based around using green energy.
