Blockchain Technology in Power Access and Exchage

1st Prize

Company:brainbot technologies AG
Project :Decentralized energy exchange based on Ethereum and Raiden

Proposal Summary:We are developing a decentralized energy exchange, implemented on Ethereum smart contracts and Raiden off-chain state channel technology. In the near future, we will see a growth in renewable energy sources like photovoltaic cells and wind turbines. Since they depend on the weather, their output is very unsteady. Our technology helps to stabilize the energy market, while using the existing infrastructure and promoting the adoption of renewable energy resources. We are creating a network in which any IoT device, like a fridge or an energy storage can trade its own energy in a decentralized market.

2nd Prize

Company:Blockchain at Berkeley
Project:bEnergy: Smart Energy Control Using Blockchains

Proposal Summary:The purpose of this project is to design and build an efficient, secure and flexible peer-to-peer energy exchange protocol. In this system, we would be using blockchain and smart contracts in coordination with Distributed Energy Resources to distribute energy from a centralized entity/ aggregator to devices in a microgrid network, which can operate independently or self-sufficiently. Moreover, we plan to minimize energy generation costs by optimizing energy dispatch loads to the microgrid network to provide a low-cost, reliable peer-to-peer energy exchange system. The blockchain structure can be used to hold immutable records of energy consumption which can be recorded and executed via smart meters/terminals and smart contracts. Thus agents in the network can audit the veracity of their consumption and payment balances.

3st Prize


Proposal Summary:Enertoken is a peer-to-peer trading platform based on the star network and Ethereum. The platform employs smart meters as a metering node of electricity data and links electrical power trade data on distributed power networks. The goal of our platform is to construct a point-to-point consensus protocol which is reliable, irreversible and capable of automatic settlement. Enertoken will realize positive interactions between the traditional power network dispatching and the market regulators. Furthermore, energy producers and consumers can also achieve efficient, convenient, safe and trackable transactions and asset settlement operations through our platform.

Full life-cycle Management system for batteries

1st Prize

Company: Filament
Project: Filament Smart Battery System Filament

Proposal Summary:Filament’s Blocklet technology uses smart contracts and blockchain ledgers to enable micro-transactions over secure communication links, even on low-power devices or where connectivity is intermittent. In the energy industry, Blocklet can facilitate peer-to-peer trading and distributed storage, speeding adoption of renewable energy sources. Blocklet also supports secure data collection, device-level access control, and attestation of battery usage.

2nd Prize

Company: BlockApps Inc.

Project:Wanxiang Smart City – Battery as a Service

Proposal Summary:The idea of “Battery as a Service” where customer would no longer have to buy new batteries but simply pay on a subscription basis for access to them. There would be no additional charges to replace batteries. Customer could easily find fully charged battery at changing stations via their mobile phones and exchange their batteries immediately so they could be back on the road in minutes. The subscriptions fees could be tracked in smart contracts and payment automatically made to manufacturer that provide replacements, charging stations, and recycling stations. This business model could be extended to “Electric Transportation as a Service”.

2nd Prize



Proposal Summary: Solve trustless by blockchain: save battery history in blockchain for immutable and traceable; use smart contract to evaluate its value for fair transaction

3st Prize

Company: Kaula, Inc.
Project:Building of an EV Battery Residual Value Prediction System - Creating Sharing Market based on Battery Life Cycle Data

Proposal Summary:Kaula, Ltd. & Device & System Platform Development Center Co., Ltd. (*DSPC) propose Battery Residual Value Prediction System(BRVPS) which dynamically analyzes State of Health (SOH) of EV battery pack and predicts its future residual value.
Once we publish prediction of residual value data in the blockchain, battery owners and users can obtain a battery with appropriate SOH in the Battery Exchange Market.
We will provide Edge/Gateway module, which gather sensing data from On-Board Diagnostics(OBD) and Battery Management System (BMS) in EV, It has very unique intelligent AI engine with Deep Binary Tree (DBT) Method.

Smart terminal regerence solution

2nd Prize

Company: μMatrix
Project: μMatrix Core

Proposal Summary: μMatrix Core, a ‘matrix’ built by hardware and applied cryptography gurus, based on chip level hardware root of trust, it will connect IoT and blockchain for a better life.

3st Prize

Company : Nayuta Inc.
Project: Blockchain based Smart Plug

Proposal Summary: We introduce blockchain based smart electric plug. This plug has the following function : authentication, payment, selection of electricity type, data gathering. When we build low power and low carbon smart city, we should consider 2 areas: (1) social public infrastructure (2) personal consciousness about electricity usage. This smart plug is key component for latter area.

Smart City Wilscards

1st Prize

Company: Factom
Project:Smart City Title Security powered by Factom product

Proposal Summary:Factom proposes to develop a title system based on its blockchain technology in order to enable the secure recording of the Smart City’s assets and allow for easy transfer of titles in the future.

2nd Prize

Company: Gem
Project: "wefficiency: the Smart Community Sustainability App"

Proposal Summary: wefficiency, a community-managed sustainability initiative, proposes an application that encourages incremental improvements in the energy consumption habits of a municipality’s residents by enabling citizens to “spend” saved energy by voting on community development projects that affect them directly. A municipal government manages community development proposals for micro-regions within a city, and issues energy conservation challenges to residents. The residents who succeed in meeting the challenges are rewarded with voting rights on how to best spend the municipality’s community development budget.
