The collaborative project “Trusted Blockchains for the Open, Intelligent Energy Grid of the Future” (tbiEnergy) explores the implementation of blockchain-supported, local energy trading for end-users.
To cater to the unique nuances of the German energy market, new blockchain solutions must be formulated, as current solutions fall short. The project places strong emphasis on a robust hardware security model in conjunction with the smart meter gateway. Employing cryptographic blockchain technology in tandem with hardware-secured IoT devices or smart meter gateways is intended to deter third-party interference within the system.
- Name: tbiEnergy
- Duration: June 2020 – June 2023
- Project partners:
- ARXUM GmbH
- devolo AG
- Infineon Technologies AG
- SWT Stadtwerke Trier
- HSB Hochschule Bremen
- Funded by: German Federal Ministry for Economic Affairs and Energy
tbiEnergy’s primary objective is to illustrate how even micro-producers can engage in straightforward, localized energy trading. Employing the value-added service model of the smart meter gateway, users can utilize blockchain technology and ‘smart contracts’ to locally market virtual goods and services. A basic example is the distribution of energy from solar cells to nearby neighborhoods.
However, this extends to more intricate scenarios, which may involve energy storage, flexibility mechanisms such as heat pumps and hot water storage, among other market assets.
ARXUM, in conjunction with its consortium partners, is diligently exploring an optimal infrastructure that would enable blockchain systems to scale and operate productively within the energy sector. Stadtwerke Trier is contributing real data gleaned from photovoltaic and wind power plants, along with combined heat and power facilities, to investigate the distinct challenges posed by the energy market in real-world conditions. ARXUM is tasked with constructing a blockchain-based infrastructure, tailoring it to actual operations to facilitate client charging and data exchanges between SMGWs and utilities. The task of conducting threat analysis falls under the purview of Bremen University of Applied Sciences, a key project partner.
The tbiEnergy project originates from the need to revolutionize local energy trading. Traditional centralized systems pose challenges for small-scale energy producers to efficiently sell their excess energy. Additionally, the rise in renewable energy sources introduces complexities that current systems struggle to manage. With the potential of blockchain technology to transform sectors, including the energy market, the project aims to leverage this technology while addressing the specific needs of the German energy market. The increase in IoT devices and smart meters also necessitates a system with rigorous security measures to protect against cyber threats. Thus, tbiEnergy focuses on creating a secure and efficient platform for local energy trading, supporting even micro-producers.
