Amazon is planning to supply hydrogen gas at its success facilities. The retail behemoth partnered with hydrogen firm Plug Energy to put in the primary electrolyzer — tools that may break up water molecules to supply hydrogen — at a success middle in Aurora, Colorado.
The electrolyzer will make gas for round 225 fork elevate vans on the web site, though Plug says it has the capability to gas as much as 400 hydrogen gas cell-powered forklifts. That is the primary time Amazon has tried to make its personal hydrogen on web site, and it’s not prone to be the final.
“On-site manufacturing will make the usage of hydrogen much more vitality environment friendly for sure places and varieties of amenities,” Asad Jafry, Amazon’s director of worldwide hydrogen financial system, mentioned in a press launch saying the set up of the primary electrolyzer yesterday. “Hydrogen is a crucial instrument in our efforts to decarbonize our operations by 2040.”
The potential environmental advantages are nonetheless arduous to measure
Hydrogen is meant to be a cleaner-burning different to fossil fuels, which is why Amazon is utilizing it at its warehouses. However the potential environmental advantages are nonetheless arduous to measure, and rely loads on how policymakers and corporations like Amazon form the provision chain for hydrogen.
Hydrogen produces water vapor as a substitute of greenhouse fuel emissions throughout combustion, a trait that’s made it extra engaging to corporations and governments working to fulfill local weather objectives. The large downside they should deal with is cleansing up the method of constructing hydrogen within the first place. At the moment, most of it’s made utilizing fossil fuels, primarily by means of a response between steam and methane. The method releases planet-heating carbon dioxide. Methane leaks are one other downside since methane — additionally known as pure fuel — is an much more potent greenhouse fuel than CO2.
Since 2016, Plug has delivered some 17,000 gas cells for forklifts to greater than 80 success facilities throughout North America. A lot of the hydrogen for these gas cells are made elsewhere, although, and Plug delivers it to warehouses by way of truck.
Producing hydrogen on web site can eliminate tailpipe air pollution from transporting the gas by truck. However for now, there are nonetheless greenhouse fuel emissions related to making the hydrogen on the Colorado success middle. Why? The electrolyzer is plugged into the ability grid, and fossil fuels nonetheless make up about 60 p.c of the US electrical energy combine.
To make actually inexperienced hydrogen, Amazon would have to ensure its new electrolyzer runs on renewables. The corporate is wanting into pairing it with renewable vitality generated on web site, however doesn’t have a concrete timeline for when that may occur, in keeping with Jafry.
The e-commerce big does have a aim of buying sufficient renewable vitality to match the electrical energy use of its operations by 2025. It additionally made a dedication in 2019 to succeed in internet zero greenhouse fuel emissions by 2040, though the corporate’s most up-to-date sustainability report exhibits that its carbon footprint has truly grown by about 39 p.c since then.
