Power Grid Worries Force Amazon To Run Oregon Datacenters Using Fuel Cells

Unable to get the power it needs to feed its growing datacenter footprint, Amazon plans to transition some of its Oregon datacenters over to natural gas fuel cells. The Register reports: First reported by local media, Amazon's initial plan would involve installing just shy of 75 megawatts of fuel cell capacity across three datacenters with the option to expand that to four additional sites in the future. Fuel cells extract electricity from a fuel like natural gas or hydrogen without the need for combustion. With hydrogen, the only byproducts of this reaction are electricity and water vapor, but with natural gas, CO2 -- a potent greenhouse gas -- is still produced.

For Amazon, these natural gas fuel cells will be used as the primary energy supply, delivering 24.3 megawatts of power to each of the three datacenter sites. 'We are investing in fuel cells as a way to power a small number of our operations in Oregon,' an Amazon spokesperson told The Register in an email. 'We continually innovate to minimize our impact on our neighbors, local resources, and the environment and this technology provides a pathway for less carbon intensive solutions in the region.'

Continuing to use fossil fuels to power its datacenters is at odds with Amazon's stated sustainability goals -- which include transitioning facilities to 100 percent renewable energy by 2025. However, sources familiar with the matter tell The Register that Amazon's decision to use natural gas fuel cells was made in part due to challenges associated with power transmission infrastructure in the region. Oregon Live notes that the e-tail giant has had problems with landowners, who have objected to having high-voltage transmission lines cross their properties. Fuel cells provide Amazon a way to circumvent these headaches by generating the power onsite. However, regulators are concerned that the decision could actually increase Amazon's carbon footprint in the region as the power supplied by local utilities includes a mix of hydroelectric power. In documents filed with the state, it's estimated the fuel cells would generate 250,000 metric tons of carbon dioxide annually.
