Systematic reduction of energy and emissions
SKF in Busan, Korea has been able reduce production related energy by 50 percent in the period 2010 to 2016.
Optimization of the compressed air systems and matching air supply to production’s immediate needs netted 17 percent. Further focused projects brought the total production energy savings to 50 percent, with the complete operations seeing a reduction of one third. In the optimization work SKF’s team used so called variable speed drives that can detect when the demand of a central systems decreases and can adjust the output accordingly.
On top of this, any compressed air system also needs continual maintenance to spot leaks and sudden pressure drops. Another common approach to such system optimization is to install efficient nozzles at the end-user to adjust the air at the machine as precise as possible.
SKF India implemented energy efficiency programmes at its five main production sites.
The programmes included reducing energy demand from machines and new energy procurement methods and innovative process development. The team in India has received numerous awards for their work ,both internal SKF awards and external recognition, among others for the integration of renewable on-site heat power generation with an industry process.
As solar panels and business models evolve it is getting more and more common to place solar panels on the roofs to cover parts of the daily needs of a general building. For energy intensive industrial processes this has proven to be more difficult, but one site in the Indian project managed to set up a hot water facility for its energy intensive phosphating process where large quantities of boiling hot water is needed. This significantly reduces the procurement of otherwise very carbon intensive electricity from the regional electricity grid.
SKF in Katrineholm's new melting shop reduced energy demand by 20%
SKF Campus Jiading in Shanghai, China, reduced energy per production output by almost 30% between 2015-2016.This was achieved by among others a new lighting system and compressed air system improvement. A newly commissioned 2,200 kilowatt solar power project was connected to the grid on January 1, 2017 this year. This will further reduce CO2 emissions from the site by 15% annually.
SKF in Mühlheim, Germany, was one of SKF’s sites to install new LED lighting in its production halls
The new system reduces energy and related emissions by 65% compared with the old fluorescent tubes. The total emissions from the site was 5% as a result. The change to LED lighting is can be seen as a “low hanging fruit”, but what sticks out with the setup in Mühlheim is that the light – which is measured in lumen – is rented as a service. For SKF this means zero investment, zero maintenance costs and a strong cash-flow from day one. The project team achieved an SKF internal Excellence award 2016 for this project.
