Övik Energi – Cogeneration & District Cooling
Hörneborgsverket, a biofuel based cogeneration plant, is the engine of Övik Energi’s energy production. Hörneborgsverket produce roughly three equal amounts of district heating, steam, and electricity. The steam is distributed to the neighbouring process industries – Domsjö Fabriker, AkzoNobel and SEKAB. Due to the industry’s need for steam, which is in demand throughout the entire year, the cogeneration plant is used to a greater extent, in comparison with power plants that only supply district heating, of which the demand fluctuates. A total of 99% of the fuels used at Höreborgsverket are renewable fuels.
Domsjö a world class biorefinery
Domsjö Fabriker is part of the Aditya Birla Group, which is the world’s largest producer of viscose fibers. We develop future textile materials from northern spruce to catwalks worldwide.
By working together with our customers, we want to make a difference. We are already involved in creating a sustainable bioeconomy that utilizes forest as the unique recourse that it is.
Algae pilot – reducing CO2 emissions with the help of algae
This Algae pilot is the first of its kind in Sweden. The algae convert unwanted substances to utilities. The goal is that algae cultivation will reduce our emissions of carbon dioxide and purify waste water to minimize over-fertilization of our waters and at the same time produce an energy-rich algae mass that is raw material for biodiesel (algae with high fatty acid content), animal feed (protein-rich algae) etc.
Innovative Use of Heat-Pumps and Solar Panels
The housing company Karlskronahem has eliminated oil from its heating systems by installing a number of different types of heat-pumps in innovative ways. One installation involves the installation of air-to-water heat pumps in the attic of apartment buildings that supply heat down to an external temperature of five degrees. The air in the ventilation is recycled through the system for heat recovery. The company has also installed solar panels for electricity production in order to become more self sufficient in terms of energy.
Congestion charges in Stockholm
The introduction of congestion charges in Stockholm was one of the reasons why Stockholm was awarded “European Green Capital 2010”. The introduction has led to reduced traffic with somewhere between 20 and 25% and that air quality has been improved, according to the Road Administration.
