The one-megawatt (MW) proton exchange membrane (PEM) electrolyser is the first for Amazon and is producing low-carbon hydrogen to fuel more than 225 hydrogen fuel cell-powered forklift trucks at the site, known as DEN8.
The Plug 1 MW electrolyser, which uses electricity and water to produce hydrogen, is able to support up to 400 hydrogen fuel cell-powered forklift trucks. The hydrogen produced by the electrolyser will be compressed on site and stored in a gaseous hydrogen storage tank for use by the forklift trucks.
“At Amazon, we have a true partner that recognises the essential role hydrogen plays in our collective energy future,” said Plug CEO, Andy Marsh. “This project demonstrates Plug’s ability to execute across the full hydrogen value chain, and shows how we can design and implement end-to-end solutions for our customers.”
To date, Plug has collaborated with Amazon to deploy more than 17 000 fuel cells to replace batteries in forklifts in more than 80 fulfilment centres in North America. For most of these locations, hydrogen to power the forklifts is produced elsewhere, liquified, and delivered by trucks to an on-site storage and dispensing system.
Plug recognised an opportunity — particularly in locations where more renewable electricity is generated than the site needs at a given time — to use that surplus electricity to produce and store hydrogen on site. This model also avoids the emissions typically generated in liquifying and transporting hydrogen from one site to another.
“Hydrogen is an important tool in our efforts to decarbonise our operations by 2040 in support of the climate pledge, and we’re excited about our ability to produce hydrogen at Amazon facilities through this partnership with Plug,” said Asad Jafry, the Director of global hydrogen economy at Amazon. “On-site production will make the use of hydrogen even more energy efficient for certain locations and types of facilities.”
For this project, Plug provided design, installation, commissioning, and maintenance services for the 1 MW PEM electrolyser and hydrogen storage—compatible with the existing refuelling infrastructure and fuel cells already in use at the site. This is the first electrolyser system installed and in use at an Amazon site.
