Towards a Blockchain-based IoT Platform for Buildings Energy Management integrating Electric Vehicles in Home Healthcare Context

Abstract

The electrification of the transportation sector, via the integration of battery electric-powered vehicles (BEV), is one of the solutions, which could help in reducing greenhouse gas (GHG) emission. Smart charging techniques with bidirectional flow, in which the electric power can flow back and forth (i.e., V2G and G2V) from/into the grid according the peak hours have been recently proposed for improving power quality and regulating frequency/voltage of the utility grid. In this paper, we aim to develop a blockchain-based IoT platform for peer-to-peer energy trading between BEV and smart buildings management systems in the context of home healthcare by using Hyperledger Besu; a private network based on Ethereum with the use of its consensus algorithm Clique. The developed platform's prototype made a success transactions of energy trading which makes renewable energy available to everyone. Moreover, the concrete implementation of consensus, transaction record layout, and self-implemented smart contracts make Hyperledger Besu a green framework for implementing the proposed blockchain-IoT system.
