Decentralized Cross-commodity Energy Management

DECENT final project presentation: IoT substrate interfacing hardware at the example of a battery

This video is a part of the final workshop of the DECENT project on April 13, 2021. During the project, several IoT communication protocols have been researched, namely OPC UA, MQTT & CoAP. Erkin Kirdan states the findings regarding security, interoperability from the specifications and several open-source libraries. Besides, Josef Schindler embeds OPC UA into a use case and presents a demo.

There, OPC UA facilitated the Machine-To-Machine (M2M) communication between a battery-boosted EV-charging-station and a generic application running on a remote client. This is a presentation from the final presentation of the DECENT project. DECENT stands for DEcentralized Cross-comodity ENergy-sharing in smarT neighborhoods. More info at

DECENT is a BMWi/ Business Finland funded project that ran from 2018-2021 with the consortium TUM, fortiss, Framatome, IBDM in Germany, and VTT, Enerim, and Wirepas on the Finnish side.

Enabling cross-commodity energy sharing for a more sustainable future! High potential lays in the more and more decentralized energy production and storage in Europe. However, the emerging flexibility potential can currently not be used due to a missing technological, economical, and legal base.

DECENT targets all three aspects:

  • The project develops an ICT solution for cross-commodity sharing and management of energy (electricity, heating, cooling and storage) in smart neighborhoods.
  • Based on the novel infrastructure, business models will be evaluated.
  • Relevant legal implications will be assessed and recommendations towards policy makers will be given.

The project follows an agile, iterative development process by setting up a virtual smart neighborhood that consists of real hardware and co-simulations distributed at the partner’s sites. The continuously tested ICT solution enables local decentralized energy trading through blockchain technology, taking into account the interests of all stakeholders. The linking of different energy resources is supported by AI and enables their optimal use across building boundaries. The evaluation of the resulting new business models leads to recommendations regarding the current legal framework.

Dr. Marc-Oliver Pahl leads the Internet of Things (IoT) Smart Space team (S2O) at the Chair of Network Architectures and Services at Technical University of Munich. The S2O team works on new ways of taming the complexity of the IoT. The goal is making a joint orchestration as simple as writing a smartphone App. Challenges include security, usability, resilience, scalability, and performance. As second research topic he is doing teaching research focusing on developing new teaching methodologies, eLearning, and learning analytics. For his teaching related activities he received the prestigious Ernst Otto Fischer Award in 2013.
