Energy web project in the blockchain with the German energy agency DENA – Ledger Insights


Today, the German Federal Energy Agency (DENA) announced the selection of the non-profit blockchain Energy web to create a digital register of distributed energy resources (RED) across Germany. These resources can include solar panels, batteries or thermostats. This Blockchain Machine Identity Registry (BMIL) is one of DENA’s three major projects for the German energy sector. Energy Web will work alongside more than 20 industry companies as well as technology companies BOTLabs, Parity technologies, and Riddle & CODE. The project is now at the stage of implementation.

DENA Future Energy Laboratory

In February 2020, the Federal Ministry of Economy and Energy commissioned the DENA to implement energy projects, as described in its blockchain strategy. DENA that launched on Future energy laboratory at the end of August, which makes it possible to experiment with energy solutions based on innovative technologies such as AI and blockchain. Future Energy Labs has three main pilot projects: BMIL, a CO2 emissions visualization solution and a smart contract ledger.

The objective of BMIL is to automatically register energy assets in the decentralized register of identities. DENA and its partners can then use the DERs for various services, for example frequency regulation and virtual power plants. This is similar to Energy Web‘s proof of concept (PoC) blockchain with Austrian power grid which demonstrated energy grid management using customer owned DERs.

BMIL will take advantage of Energy Web’s decentralized operating system (EW-DOS), an open source decentralized software stack that uses various technologies, including blockchain, and runs on a decentralized network. For digital identity, EW-DOS will be used in conjunction with the KILT blockchain protocol that delivers verifiable, revocable and anonymous self-sovereign credentials and Parity substrate, which allows companies to create custom blockchains. Energy Web claims the solution is the first energy project to use a “multi-blockchain architecture”.

Technology partners

Ingo Rübe, CEO of BOTLabs, the company behind the KILT protocol, highlights the importance of DERs and asset identities in the energy sector. “Decentralized identifiers and verifiable credentials are key elements of a larger decentralized technology solution to support energy transitions. “

RIDDLE & CODE is a company that deals with the interface between blockchain hardware and software. CCO Sebastian Becker confirms that he will use two of his flagship projects to support the DER ID blockchain ledger. One is a collaboration with mining technology developer S1Seven for better traceability and certification practices in the metals industry. “In order to connect these projects to the BMIL ledger, EW and RIDDLE & CODE will leverage their innovative blockchain infrastructures, namely the professional services layer of the IPDB Foundation open source stack on our side. The IPDB uses yet another technology, BigChainDB.

Energy Web CEO Jesse Morris believes this is a critical step for global energy. “This is an incredible development not only for Germany but for the global energy sector. Now we have the electricity sector of the world’s fourth largest economy taking decisive steps towards a decentralized and digitized future. “

Some have predicted that Germany will not be able to meet its energy targets for 2020. At the end of 2019, McKinsey estimated that the country would meet its CO2 emissions targets for only eight years later., Meanwhile, the German Minister of Economy Pierre Altmaier confirmed at a press conference that the goal of producing 18% of its total energy consumption with renewable energies is still within reach after reaching 17.1% in 2019.
