Vodafone Business will integrate IoT and blockchain technologies thanks to its sim cards used for renewable energy resources distributed within electricity grids. 

This was announced by Energy Web, a non-profit organization working on a low-carbon, customer-focused, blockchain-based, power system. 

In particular, Energy Web works on the development and integration of technology, creating standards and architectures.

In mid-2019, it launched the Energy Web Chain, an enterprise-level open-source blockchain platform designed explicitly for the needs of the energy market. 

Thanks to the new partnership with Vodafone Business, the blockchain will be used on SIMs with IoT connectivity to create secure IDs for energy resources

The goal is to integrate renewable and distributed sources, such as wind turbines, batteries, heat pumps and solar panels, securely and efficiently with energy networks.

The blockchain will be used specifically to securely identify SIM cards, so that energy grid operators can securely recognize distributed resources connected to the grid. This is made possible by the integration between the IoT connectivity provided by Vodafone Business and the decentralized Energy Web operating system, EW-DOS. 

Vodafone Business already has experience in providing IoT solutions to energy producers and distributors worldwide, and this further step demonstrates the company’s commitment to innovation based on new decentralized technologies. 

SIM cards for IoT connectivity that integrate blockchain technology will be able to provide proof of identity to network operators with a pair of public and private keys.

In this way, network operators will be able to query SIM cards by having their identity confirmed with certainty, directly from the SIM, and without having to rely on third parties.  

More specifically, Vodafone Blockchain leader, David Palmer, revealed that the private key infrastructure of these SIMs allows them to sign transactions on the Energy Web blockchain. 

Energy Web’s CEO, Walter Kok, added: 

“We are seeing the convergence of multiple sectors in making the energy transition happen — the energy sector, of course, but also automotive, telecoms, and even finance. From our perspective, the energy sector can only evolve so fast and so far without taking into account IoT connectivity. Bringing together EW’s expertise in energy and decentralization with Vodafone Business’s leadership in IoT creates a really powerful combination”.

Vodafone Business’ Director IoT, Erik Brenneis, commented: 

“As the number of decentralised, new-generation, low-carbon devices grows, so does the need for them to be securely connected regardless of their location. This connection needs to be simple and secure, ensuring assets are easily able to be connected to, and managed by, energy and communication networks around the globe. At Vodafone Business IoT, we believe that technology and connectivity can be used to help protect the planet and improve people’s lives. We are proud to work together with Energy Web to make this a reality”.
