A Current Perspective Conclusion

> Combining Economic Growth and Climate Change


Germany’s national target: - 40 % GHG emissions by 2020 vs. 1990 (facilitated through reunification: breakdown of heavy industry, fuel switch, energy efficiency in former GDR; altogether ca. 10 %)

2007 integrated energy and climate programme, 29 measures, estimated to achieve 32 to 35 % Combining energy efficiency and renewable energy;

nuclear phase-out; CCS not yet (except pilot plants)

Analysis: ◦ 24 billion Euros/year of investment;◦ 29 billion Euros/year of annual savings in 2020;◦ Net employment growth 500,000 by 2020; 800,000 by 2030

Energy Saving Potential of Cross-Sectional Technologies

- most companies could potentially reduce their consumption of electricity and associated costs for these cross-application technologies by 5 % to 50 %

- the payback period is less than two years and the return on investment is more than 25 % > measures that improve energy efficiency are extremely appealing to companies for economic reasons

- Exchanging single technologies doesn`t require the change of the production process

The electricity required to generate compressed air can account for 20 % to 80 % of the overall energy costs in a company

Compressed Air

Compressed air is used in the following areas:

- Pneumatics- active air (compressed air as a means of transport)- process air (for example, drying processes)- vacuum technology


General approaches for improving efficiency:

-improved heat insulation-reduced heat radiation-adjusted “busy” times and operating times-basic process design-optimised power, pressure and temperature levels-efficient control technology-detailed design and selection of individual components-use of thermal cooling machines, for example, with solar heat, district heating, industrial waste heat as well as waste heat from combined heat and power systems (CHPs)

Refrigeration Technology


- in refrigeration technology, there is often great potential for reducing energy costs

this concerns the continuous operating costs of such systems, which may account for up to 80 % of the total costs associated with a refrigeration system


Energy saving

Percentage of electricity consumed among motor-driven systems within the EU

Pumps

• Pump systems presently account for a good 25 % of the industrial electricity consumed worldwide

• Large market share of Centrifugal and displacement pumps

• on average, companies can reduce the electricity consumed by their pumps by approximately 30 % (accord. to a DENA study)


Heat pump

Fuel saving

investments in energy saving can often be amortised within just a few months

• Lifecycle Costs > the costs associated with electricity consumption accounts for up to 96%

• Not primarily the motor determines the optimal efficiency; it is the way the speed is controlled

• The EN 60034-30:2009 standard defines worldwide efficiency classes of low-voltage three-phase asynchronous motors

• consume 64 % of all electricity used in industry

Electrical Drives and Engines

Lifecycle costs of an electric motor:


Process Heat

• Process heat is the heat required for numerous technical processes and procedures in trade and industry

necessary for cooking, baking, sterilising, drying, smelting, forging, welding and producing steam

• Increased energy efficiency is mostly achieved by optimizing the system technology

Optimization of the combustion/boiler technology/

Improvement of heat insulation

combined heat and power (CHP) or combined cooling and power (CCP)

Heat recovery


Waste Heat Recovery

Heat recovery measures result both in:

• lower energy costs by reducing the use of primary energy, and

• in lower investment costs for heat production plants

Heat recovery can reduce:

• the connection power for heat energy and cooling energy,

• the level of energy consumption for heating and cooling,

• investment costs and operating costs as well as pollutant emissions
