Engie and Ledger have developed a hardware blockchain solution for storing data generated by green energy sources.

    A few years ago, the expression “everything is getting better with Bluetooth” has become, one may say, a meme. Nowadays, Bluetooth has replaced blockchain - not in the sense of replacing one technology with another, but in terms of meme modification. The word "blockchain" is used by all and sundry, by the way or not by the way.

    But there are also cases when this technology is used quite reasonably. For example, it is introduced into cadastral solutions, used to work with all sorts of registries, not to mention cryptocurrencies. Now blockchains are trying to put themselves and energy workers at work in order for information from power sources to go to a safe storage facility, from where it could be taken for use in various kinds of applications - basically industrial solutions are meant.

    Two companies, Engie and Ledger, created a hardware solution for this very purpose. Thus, information on the operating mode of various “green” energy systems, whether wind generators, solar panels or something else, is stored in a specialized storage facility, which is practically not subject to hacking. Nevertheless, these data remain available - they are planned to be used to monitor facilities in real time, to conclude contracts for the purchase or sale of energy, or for other purposes.

    Working prototypes of the system have been installed at several wind and hydro power plants. They allowed ENGIE to create its own certification platform for its customers, which makes it possible to track virtually any parameters of various infrastructure elements. The solution is compatible with almost any blockchain technology and platforms.

    This project is one of the first attempts to create a reliable network of storage and exchange of data on the work of various elements of the energy infrastructure. Such a network will help to exchange data in real time for solving various tasks, including the transfer of energy to regions where during peak loads there is not enough of its own resources. But this is just one example, the possibilities are much greater.

    The company Ledger is known for its hardware solutions for blockchain and cryptocurrency. For example, Ledger Nano S is a hardware wallet for storing various cryptocurrencies, which is considered one of the most reliable. It provides complete isolation of the cryptograph from the PC or smartphone.

    It is difficult to judge what constitutes a new solution for the energy market, but, probably, the principle of its operation is similar to the principle of operation of cryptocurrency wallets produced by Ledger.
