Jemena Power to Gas Demonstration

closed

The Jemena Power to Gas Demonstration project involves designing and constructing a Power-to-Gas (P2G) facility which will source renewable electricity and convert it into hydrogen via electrolysis.The majority of the hydrogen produced will be injected into the gas network, providing enough energy to meet the cooking, heating and hot-water requirements of approximately 250 homes. A portion of the hydrogen will be utilised via a gas engine generator for electricity generation back into the grid with the remaining stored in an underground hydrogen buffer store with the capability to provide hydrogen for a future onsite Hydrogen Refuelling Station (HRS).How the project worksThe Jemena Power to Gas Demonstration project consists of constructing a 500kW electrolyser in western Sydney to convert solar and wind power into hydrogen via electrolysis.The five year trial will see hydrogen injected and stored in the Jemena Gas Network, Australia’s largest gas distribution network, to demonstrate how existing gas pipeline infrastructure can be repurposed to store excess renewable energy.The trial will explore how this approach could be adopted more broadly across NSW and lay the foundations for a future renewable energy grid.
