To increase the efficiency of industrial processes and at the same time optimize energy consumption, energy management is considered one of the most important tools in today's industry - just like at Jumo.

The description of energy was heavily influenced by the scientific, technological, and industrial developments of the 19th century. During this period, humanity underwent a significant transition from the use of predominantly mechanical energy to chemical and electrical energy sources. Mechanical energy initiated and drove the industrial revolution.

Carrier carbon cycle

The energy from the movement of machines, using wind and water power, was often described as "mechanical work". The use of fuels (chemical energy) such as wood, coal, and later petroleum and natural gas led to the most revolutionary development of the time - steam engines, whose thermal energy was converted into mechanical work or into electricity.

However, it should be noted that the storage of CO2 in plants through photosynthesis and the thermal release of CO2 through combustion is a recurring, slow and lengthy carbon cycle. Due to overburdening of the carbon cycle by mass CO2 combustion and slow storage, only a significant reduction in CO2 will lead to a noticeable reversal of the trend in CO2 levels in the atmosphere. Initially it was thought that fuel was available infinitely and inexpensively, but economic growth, competitiveness and subsequent cost reduction measures demonstrated that energy costs are a significant part of industrial operating expenses today.

Knowing where and how the energy flows

To increase the efficiency of industrial processes and optimize energy consumption at the same time, energy management has become one of the most important tools in today's industry. The implementation of energy management technologies often promotes and leads to technological innovation because they know where and how energy flows. Companies that continuously invest in energy-efficient technologies can not only improve their energy balance but also become more competitive globally. More and more customers expect industries to provide CO2 evidence that the products purchased are produced more and more sustainably year after year. Many countries have also introduced laws and regulations that require industries to monitor and reduce their energy consumption.

Reduce energy consumption further

An energy management system helps to meet the increasingly demanding legal requirements. By reducing energy consumption, Jumo will further minimize its environmental impact and contribute to more sustainable development without affecting its productivity and quality. For this, Jumo has developed and installed its own energy management system for the water chillers in the main plant in Fulda. Important components of this energy management system are:

  • the energy management software, e.g. Jumo Cloud,

  • the energy management system, e.g. Jumo Smartware SCADA,

  • the regulation, e.g. influencing a heating system based on a target-actual comparison,

  • the control, e.g. influencing a heating valve to influence the room temperature,

  • the sensors, e.g. for temperature, pressure, power.

New building in the Technology Park Fulda-West

With existing older industrial buildings, the reduction measures of the ecological footprint continually reach their limits. This leads, among other things, to the largest investment in Jumo's history, a new building in the Fulda-West Technology Park. With around 50 million euros, the company is successfully setting the course for a sustainable future. After all, around 13,000 m² - equivalent to approximately two football fields - will be available for modern production of temperature and pressure sensors. A lot is also happening in the new factory in terms of innovation, digitalization and sustainability. According to current planning, fossil fuels will be completely avoided there. A geothermal system is to be used to support heating. This will cover peak load, with base load being covered completely by heat recovery from production processes. The electricity demand of the production facilities will largely be covered by its own power. The cooling and ventilation systems of the new plant will mainly be operated with self-generated electricity from its own photovoltaic system. Overall, all energy processes are aimed at minimizing the CO2 footprint and fully utilizing the existing energies.

The importance of sustainability is increasing

  • The European Green Deal aims to make the EU the world's first greenhouse gas neutral bloc by 2050. European companies are urged to disclose and improve their CO2 footprint. For companies, this means initially getting an overview of where which CO2 emissions occur in the company by determining the company-wide CO2 footprint (Corporate Carbon Footprint).

  • According to the Greenhouse Gas Protocol, the CO2 footprint is divided into three scopes. The first scope includes the direct emissions in the company (e.g., heat, cold generation, vehicle fleet, etc). The second scope includes the indirect emissions, e.g., from energy suppliers (electricity, heat, gas, steam, etc). The third and last scope covers the indirect emissions in the upstream and downstream supply chains.

  • Since 2023, medium-sized and large companies have been required to report their CO2 footprint according to the legal requirements of the CSRD Directive (Corporate Sustainability Reporting Directive, EU Directive on Corporate Sustainability Reporting). The requirements, processing and reporting of energy data in a company can thus become a major challenge. Especially in industries with complex processes and numerous influencing factors, such as in process engineering or machine manufacturing, like at Jumo in Fulda, various energy flows have to be considered and evaluated.

  • An expandable digital energy management system is, so to speak, at the center of the processes and orchestrates the most diverse energy flows. This digital solution ensures the ongoing monitoring (e.g. every quarter of an hour, quasi-continuously, ...) and optimal control of energy production, consumption and storage and operates largely autonomously. Optimal are learning digital systems, because they calculate the optimal energy flow based on forecast data and balance deviations in real time.
