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 #637: Mutriku Breakwater Wave Plant, Mutriku, Spain

Located on the northern coast of Spain in the Basque country, this ingenious power plant leverages the motion of the waves against a breakwater to generate power. The breaking waves push a series of columns of air. The moving air drives 16 generators.

By the way, I made a mistake in the hint — the 70,000 homes number comes from the previous contest (Steven’s Croft). Mutriku generates about 300KW, or enough to power about 250 homes. To be fair, I’m sure the “Basque” part of the hint was way more useful to people that needed it than the output number could have. I fixed it on Thursday, but, if that threw you off and kept you from entering the right place, comment here and we’ll consider giving you the point.

Contest #636: Steven’s Croft Power Station, Lockerby, Scotland

Steven’s Croft is a biomass plant — the largest one in the UK. It runs completely on wood, most of which it receives as by-products from the mill next door.
