Renewable energy resources such as solar PV and wind generation are producers of intermittent power necessitating ample dispatchable power reserves in the event of cloudy weather or a lack of wind. Increasing amounts of Distributed Energy Resources, (DER) such as intermittent renewable solar and wind energy sources within the grid will challenge the grids stability depending on the degree to which the grid is interconnected to other systems and the percentage of variable renewable penetration within the system.
At the same time Distributed Energy Systems (DES) could offer greater reliability, the paradox of DER is that it is initially a destabilizing factor to grid operations and costly to apply, but in time they become a stabilizing influence as and when the grid has adapted to its presence with the right mix of the appropriate technologies.
Energy Storage will play a vital role in grids that transition from 35% variable renewables to 100% renewables, all forms of energy storage will be relevant, some becoming more relevant offering opportunities beyond just energy dispatchability as the ratio of renewable penetration increases beyond a certain percentage.
In this presentation we discuss some of the components and tasks of a future energy system made up of DER in various system guises that contribute to its overall reliability and resilience. We will talk about the role Hydrogen will play as a storage medium referencing the world’s largest PEM Electrolysis plant in Mainz EnergiePark in Germany. We will also talk about the potential for Australia becoming an exporter of their vast variable renewable energy resources which up to now have been regarded as a stranded asset, an export industry that could potentially rival that of Australia’s current LNG industry in the long term.
3 key takeaways from this presentation:
1.The need for large scale energy storage and dispatchability
2.Green Ammonia as a fuel for export and the economics
3.Cross sector coupling, Gas networks & Transport.
