Energy efficiency

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:

Improved thermal and non-thermal insulation

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.

Reusing waste heat

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.

Decarbonizing municipal heat

Converting the heat supply to renewable energy sources means that municipal utilities are confronted with a wide range of technical and economic decisions.

The ScaleGrid solution, which Bilfinger played a key role in developing, delivers

  • a site-specific potential analysis for renewable heat sources
  • development and evaluation of technical options
  • market-oriented optimization of energy and heat in the integrated business model
  • a structured decision-making process.

As a result, the utility is provided with an optimized investment roadmap that takes into account all of the uncertainties in the economic conditions and municipal specifications.

Thermal heatflow optimization

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.

Extensive saving potentials exist in almost every industrial plant. We can implement energy efficiency measures quickly without major changes to existing infrastructure.

Energy efficiency projects

An abundance of energy (Stadtwerke Duisburg)

With Bilfinger's support, a district heating accumulator was added to Stadtwerke Duisburg's combined heat and power plant in 2018. With a storage volume of 43,900 cubic meters of water and innovative dual-zone storage technology, it is one of Germany's largest and most modern heat accumulators. Bilfinger acted as general contractor for this landmark project for the entire storage facility, including construction work, basic and detail engineering, integration into the existing facility, manufacturing, delivery, assembly, commissioning and documentation.

Bad actor analysis (Münzing)

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.

Greater efficiency with TIPCheck (DSM)

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.

Construction of a heat-pump system (Heineken)

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.

Smart heat network for a sustainable future (Enpuls)

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.

Less CO2 with circular district heating system (050 Buurtwarmte)

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.
