About The Hydrogen Mini Grid System

The Hydrogen Mini Grid System (HMGS) is an innovative demonstration project designed to showcase the latest hydrogen technology and to push the boundaries of current thinking. The HMGS utilises free wind energy to generate electricity from an onsite 225kW wind turbine. It is estimated that the wind turbine will generate in excess of 500MWh a year - more than enough to provide electrical power to the EETC building.

Excess electricity from the wind turbine will be used to generate hydrogen through electrolysis. This hydrogen will be pressurised from 30bar to 200bar and stored on site for later use, either as a transport fuel or to provide electricity, through a fuel cell, during periods of low wind speed.

Uniquely, the HMGS is configured to enable electricity, from both the wind turbine and the hydrogen fuel cell, to be supplied directly to the local distribution network.

Our Aim

The aim of the Hydrogen Mini Grid System is to demonstrate the use of Hydrogen as a truly "Green" alternative to conventional hydrocarbon fuels for both transport use and electricity generation.

Our Objective

The objectives for the HMGS are:

1. To help make the EETC a Carbon Neutral facility
2. Demonstrate state-of-the-art hydrogen technology
3. Provide an internationally recognised prototype of a Hydrogen Economy
4. Promote Yorkshire as a hotbed for hydrogen and new energy industries

System Components

The HMGS consists of:

1. 225kW Vestas wind turbine
2. 30kW electrolyser operating at 30bar
3. 200kg high pressure storage facility
4. 30kW fuel cell - grid synchronised
5. Hydrogen vehicle refueller

Power Generation

The HMGS can supply mains, 240v, electrical power directly from the onsite wind turbine or the grid synchronised hydrogen fuel cell. In addition, the HMGS can supply high pressure, 250bar, hydrogen suitable for refuelling hydrogen vehicles or refilling hydrogen bottles.
