Efficiency PACK

Exploiting waste heat in industrial processes and power generation systems

January 2021
Gallery Efficiency PACK 1
Gallery Efficiency PACK 1


The complexity in designing ORC plants meant only niche applications with large uniform heat sources, e.g. geothermal, could be exploited commercially. Orcan developed a new generation of ORC products based on a modular design. These ORC units are much more versatile and feature significantly lower LCOEs, even reaching the level of baseload electricity driven by fossil fuels. Orcan is the leading supplier of such modular and compact ORC products, both in terms of the number of ORC units installed as well as cost-effectiveness. By converting a complex thermodynamic system into a plug & play product, the technology has been made available for mass application. The Efficiency Packs are designed in a way to reduce project-specific engineering effort. The final ORC unit was designed with manufacturability in mind. Cost positions previously only available in large-scale ORC plants, can now also be achieved in the small- to mid-scale waste heat market.

Implementation Stories

Efficiency PACK by Orcan Energy AG
Implemented by Portlandzementwerk Wittekind Hugo Miebach Söhne KG in Erwitte (Germany) in 2021

The long-established family-owned Portlandzementwerk Wittekind Hugo Miebach Söhne KG from Erwitte in southern Westphalia has signed a contract in 2021 for six energy efficiency modules from Munich-based waste heat specialist Orcan Energy. With the plant modernization, the cement plant intends to generate additional electricity and significantly improve its eco-balance through sustainable energy generation. The waste heat project at the Wittekind cement plant was funded by the German Federal Ministry for Economic Affairs and Energy as part of a funding competition. As a result of the funding, the payback period for the project was reduced by around half. The project started in mid-2021, and commissioning was completed during the first quarter of 2022.


The eP 150.200 efficiency Packs lead to savings on the existing cooler and convert the waste heat generated during energy-intensive cement production on site into a total of up to 8,000 megawatt hours of electricity per year.


The environmental benefits

  • The Efficiency packs can effectively use waste heat from 80 to 800°C
  • The plug & play waste heat recovery solution can be installed and put into operation in less than 24 hours
  • Efficiency PACKs are able to generate carbon-free baseload electricity 24/7
  • A single efficiency PACK can save 750 tons of GHG annually and has an environmental payback time of less than 2 months
  • By mid-2020 Orcan had avoided over 30,000 tonnes GHG throughout their rapidly growing fleet of ORC units worldwide
  • With Orcan efficiency PACKs 13 million tonnes of GHG emissions could be avoided when fully utilising the entire German industrial waste heat

The Financial benefits

  • Orcan's ORC solutions have payback times starting from 2 to 4 years
  • The world’s largest installation of modular ORC units located in Myanmar provides electricity to 100,000 households and helps to meet Myanmar’s rapidly growing electricity demand
  • With Orcan ORCs over 17% of German households could be supplied with electricity when fully utilising the entire German industrial waste heat - this amounts to electricity worth € 3bn annually
