A full-scale wind hydrogen energy plant [50] and testing facility began operation in 2007 on the island
of Lolland, Denmark. During some periods wind power produces 50% more energy than is needed. The
project will store the excess wind power as hydrogen for use in residential and industrial facilities.
An ultraviolet water purifier powered by renewable energy was tested by USDA-ARS and AEI [51].
A controller was developed and five configurations were tested, two with PV (100 W), two by wind
(500 W), and one by hybrid wind/PV. The PV-only system is more efficient and cost-effective than
the wind-only system. However, the wind/PV system is more reliable in terms of power. The system
purified 16,000 L/day, which is enough potable water for around 4,000 people at an estimated equip-
ment cost of around $5,000. In Afghanistan, water is purified by using ozone produced from electric-
ity from a wind/PV hybrid system. The technology is a small system, which used around 160 W to
produce 2 g of ozone per hour. Treatment is on a batch basis of 500 L to produce 2,000-4,000 L/day.
The system is powered by a 1 kW wind turbine, 280 W of PV, a small battery bank, and an inverter.
