Contest #639: Taleghan Solar Hydrogen Energy System, Iran

Yeah, that was a tough one. Hearty congrats to those who found it, especially before the hint.

Taleghan is a hybrid solar energy plant. During the day, a portion of the energy produced by the PV cells is used to hydrolyze water to obtain H2, which is stored in high-pressure tanks until needed. At night, that hydrogen is used to drive fuel cells, which replace the solar generation.

Contest #635: Hornsdale Windfarm, Australia

The problem with most forms of renewable electricity generation is that they are dependant on fuel sources that can’t be controlled by the generating entity. Wind is a perfect example — wind can not typically be used for “base load” because, oddly enough, sometimes the wind does not blow.

Hornsdale is a step in fixing that problem. By storing the generated electricy in the world’s largest battery bank (provided by Tesla), that power can be tapped when the wind does not blow hard enough to meet the needs of the local community. This is a pilot project, but it does provide a first step in providing scalable solutions to turn renewable generation into base load capable generation.
