Pre-study on the blockchain applications in an innovation district

An innovation district with offices for up to 10,000 people will be constructed within a large German metropolitan area till 2025. On site, an area of 90,000 m2 will be developed with a floor space of 241,800 m2. It includes 3,000 parking spots, 1,400 of them will be equipped with charging points. In addition to commercial and office spaces, living spaces for temporary and permanent residents will be provided. Electricity will come from PV plants in the district and the neighborhood and stored in the battery storage over time.

In this context, there is a special interest in opportunities of using blockchain technology. In a short study under contract from OLI Systems GmbH, Dr. Langniß – Energie & Analyse analyzed the potential based on specific applications, which are applicable to the innovation district. To these applications belonged tokenization of (energy) services, smart charging of electric vehicles, heat utilization and storage, battery storage, as well as PV (self-generation & integration of external plants). Economic efficiency of different applications and synergies between them were demonstrated. The study results were presented at an internal workshop with the customer and at an investor meeting.

Sector coupling and neighborhood with blockchain tokens for an innovation district – outline preparation for idea competition „Living labs of energy transition“

In an innovation district in development within a German metropolitan area an integrated and interactive energy concept is put into practice. Data driven technologies will be applied in a system facilitating manner. As such they will get analyzed: a building information model (BIM), high resolution (by time) measurement and control concepts for energy management and blockchain for agent-based trade of energy resources. Energy supply will comprise a set of completely renewable based components, such as PVT collectors for combined electricity and heat production, a low ex system for combined heating and cooling as well as the development of optimized operation strategies applying artificial intelligence. A blockchain technology-based market place will be created where players or assets in the district or from the neighborhood can carry out energy related transactions in an automated manner. Sustainability tokens are supposed to incentivize and reward sustainable behavior in the sense of a district’s currency.

The project leader for the district’s development charged Dr. Langniß - Energie & Analyse with the coordination of a funding project outline for the idea competition of the German federal ministry for economics and energy (BMWi). A consortium of eight partners, technology companies as well as research organizations and a regional manager being part, outlined the project collaboratively.



  • Draft of the funding project based on the urban management plan for the district
  • Acquisition of additional partners in the environment of the consortium consisting of both enterprises and research partner
  • Coordination of the whole process of outline preparation and submission

Funding application support for Stadtwerke Heidelberg

Grid operators and energy providers are becoming increasingly active in facing the challenges imposed by the growing share of decentralized generation and the increasing importance of information and communication technology for their business. Stadtwerke Heidelberg plan to realize innovative concepts in the areas of urban district supply, mobility and connected energy data services.

For Stadtwerke (municipal utility) Heidelberg, three proposals for national funding initiatives have been developed and prepared. One proposals aims to study and test a building block consisting of a combined battery storage unit and adjustable local grid transformer. In another proposal, Stadtwerke Heidelberg is going to develop and study an Open Source data platform for real time energy data. Thirdly, former barracks shall be converted into an “energy quarter” with integrated data- and mobility concept, an approach unique in Europe.

Conceptual development of the proposals together with Stadtwerke Heidelberg and production of proposals ready for submission.

Umweltbundesamt - Overview and oriented assessment of decentral energy management systems

The energy sector is in the state of radical change, driven by technical developments like (distributed) renewable energies, digitalization and political goals as climate protection and opting out nuclear energy. Within this process, only in Germany more than 1.5 million of decentralized power stations were developed, with a rising trend. These decentralized plants are increasingly equipped with intelligent control devices, which perform controlling tasks beyond the mere assurance of the functional capability of power stations. So, e.g. consumers and storage devices are settled in a such way that own consumption of electricity from decentralized plants will be maximized.

The short study, which was compiled together with Öko-Institut in Freiburg, provides an overview of decentral energy management systems and a classification in terms of their ability to support overall system integration. A representative selection of systems is evaluated qualitatively and in an exemplary way with regard to their impact on different areas of the electricity system. These includes the impact on the electricity grid, the flexibility needed in the system and effects on energy consumption. This is followed by an overview of relevant ecological and social sustainability indicators. In the outlook the open questions are outlined, which should be answered within the long study on this theme.
