Technology giant Apple is set to double the size of the fuel cell power plant in one of its data centres, making it the largest non-utility fuel cell installation in the US.
The 5MW installation will be on top of its existing system in Maiden, North Caroline, which is expected to provide more than 40 million kWh of renewable energy every year.
The fuel cells will be powered by biogas, a by-product of the decay of organic matter, from landfill. The initial 4.8MW installation began start-up and testing in October this year and the full 10MW plant is expected to be operational by January 2013.
The project sees Apple surpass the online shopping firm eBay, which earlier this year announced plans for 6MW fuel cells to power its data centre in Utah.
