Improving the energy efficiency of plants is the most obvious, simplest and, generally speaking, the most affordable way for operators to reduce energy consumption. Because clearly, energy that is not consumed does not generate emissions or costs.
Experience from hundreds of energy efficiency projects demonstrates the extensive savings potential that exists in almost every industrial plant. Energy efficiency measures can usually be implemented quickly and without major changes to existing infrastructure. Relevant measures can include:
As Bilfinger Industrial Services Austria, we are acting as the general contractor for the district heating tank project at Stadtwerke Duisburg and managed to convince the customer thanks to our outstanding cross-departmental cooperation and our expertise."
Decarbonization presents municipal utilities and industry with a complex set of challenges - with ScaleGrid, we deliver a forward-looking and sustainable solution. With the development of an integrated strategy, we help our customers make informed decisions today to be well positioned for the future."
With our TIPCHECK, we can precisely calculate energy savings potentials for our customers and make recommendations on how to lower CO2 emissions. With little time expenditure, we can transform operational plants in an energy-efficient manner - and we do it according to the individual needs of each customer."
Increasing requirements of the future, such as climate protection and mobility, present a number of challenges. At the same time, they offer enormous opportunities to develop innovative technologies. We help our customers solve the challenges and take advantage of the opportunities with a comprehensive portfolio of services."
Quick successes can be achieved with the help of Bilfinger's TipCheck analysis - avoiding heat loss or identifying areas with high levels of energy consumption, for example. The "Technical Insulation Performance Check" highlights energy and heat losses caused by poorly insulated components - thereby helping to identify and implement suitable measures such as applying insulating materials to these components.
Substantial energy saving potential can be harnessed if the waste heat generated by a plant during production is reused within the plant's own processes. External users such as neighboring industrial plants or district heating networks can be provided with the excess heat energy that has been generated. Bilfinger supports this process by designing and supplying modular solutions that allow for the capture and reuse of waste heat.
The shift in heat supply to renewable energy sources means that municipal utilities as operators of district heating networks must make far-reaching technical and economic decisions. The transition makes new value chains between municipal utilities and industrial companies possible. The heating turnaround requires a sound strategic realignment that also allows flexible responses to changing economic conditions or weather-related fluctuations in feed-in to the grid.
The ScaleGrid solution, which Bilfinger played a major role in developing, uses smart software to deliver:
- a site-specific potential analysis of renewable heat sources,
- development and evaluation of technical options for operators,
- market-oriented optimization of feeding waste heat or green electricity into the grid or storing it for peak loads,
- and a structured decision-making process.
Our clients are provided with an optimized investment roadmap for a resilient and scalable supply network, which ensures load security and clear planning steps for a gradual decarbonization of the respective municipality.
Bilfinger uses the pinch analysis to achieve an optimal heat circuiting between process flows. It evaluates the cold and heat flows of a process and, in addition to an evaluation of the current situation, also provides a theoretically ideal system status. Based on this ideal status, Bilfinger then develops an individual concept with highly effective measures to optimize the use of heat.
District cooling, an environmentally friendly alternative to air conditioners
Services: Bilfinger is supporting Stadtwerke München with the planning, installation and commissioning of their new district cooling centre. When completed, this district cooling centre will be the largest in Germany, and up to 100 office buildings can be cooled when finished.
Using a bad actor analysis, unusually high energy consumption can be identified quickly. This requires the merging the data from energy meters with production and operating data. Bilfinger developed a solution for Münzing Chemie that intelligently links the relevant data and immediately displays major deviations from average values on a dashboard.
Dutch chemicals group DSM is planning to reduce its energy consumption by 15 percent between 2015 and 2025. Bilfinger is supporting DSM in the implementation of this goal with three TIPCheck analyses. Based on the results of these analyses, the industrial services provider developed a large number of site-specific measures for energy management, steam, cooling, compressed air systems, heat integration and waste heat recovery.
To increase energy efficiency through the use of waste heat, Dutch brewery group Heineken built a 9 MW hot water heat pump system. Bilfinger was responsible for conducting feasibility studies and a modeling study (waste heat supply versus heat demand) as well as for the concept design and the basic design, including specifications and supplier evaluation.
Bilfinger developed a concept for an intelligent heating network for Dutch environmental service provider Enpuls. The core components of the concept include solar thermal collectors and a thermal accumulator. Bilfinger was responsible for the concept design, basic routing of the heating network and the dynamic system modeling, among other things. Bilfinger also designed the pump station.
In the Dutch city of Groningen, Bilfinger is working on a circular district heating system in cooperation with the organization 050 Buurtwarmte. Using high-temperature heat pumps, the project will significantly reduce the CO2 footprint of the Groningen's Paddepoel district. Bilfinger was responsible for the concept design and advised the organization on safety, noise, air and permits.
