Traditionally, Australia’ energy is derived from the electricity grid infrastructure, but the ability to shift to renewable energy, including green hydrogen, has developed significant interest and can combine several technologies.
Solar PV systems have significantly reduced in cost over the past two decades and forecasts have been made that the capital cost of hydrogen electrolysis will also significantly reduce, potentially up to 75% over the next 3 decades for large scale systems (Böhm et al., 2020). With some of the highest solar irradiance levels on the planet, significant land availability, and an advanced economy and a comparatively stable political environment, Australia has a natural advantage for generating green hydrogen using solar PV.
Green Energy Source PV systems have made significant advances in Australia, with access to green hydrogen through surplus solar production beginning to emerge. PV energy can be generated through several configurations, including rooftop solar, solar farms, and floating solar.
On buildings or car park shade structures is an easy way to produce green energy, albeit peak energy generation may not coincide with peak electricity use.
Several projects have implemented solar systems and concurrently shifted power load activity such as pumping.
Of course, roof top area or suitability at some locations is a limiting factor and other forms of solar need to be considered.
Solar farms are also found at some projects where they have available land area or adjacent land with agreement of the landowner. Investment in ground mounted solar needs to be considered with future plant expansion requirements.
On water bodies are becoming a commercial reality and have the benefit of providing area for power generation whilst reducing evaporation and the proliferation of algae that can affect water quality.
