In a similar vein, Grid Singularity, a European startup, is concentrating on exchanging detailed and confidential data among various entities within the energy market.
Major energy corporations are also joining the fray. British Petroleum p.l.c. (BP) and Austria’s Wien Energy were among the firms that engaged in an energy trading platform trial earlier this year. (Refer also: How Blockchain Is Facilitating Changes in Government Services.)
Another prevalent use case for blockchain within the energy sector is the creation of cryptocurrencies for financial transactions. Several utilities have already initiated pilot projects to facilitate such transactions. For instance, Marubeni Corporation (MARUY) accepts cryptocurrency payments in certain Japanese regions. In specific instances, the utility of blockchains transcends payments. For example, Bankymoon, a blockchain startup based in South Africa, collaborated with Usizo to facilitate cryptocurrency financial transactions for bitcoin-compatible smart meters situated in isolated areas.
However, this merely represents the inception. Blockchain could catalyze additional alterations within the energy ecosystem. For instance, a distributed ledger encompassing numerous energy consumers and producers could result in multiple rates within markets, as opposed to the singular utility-determined rate that is currently predominant.
