The hydrogen power company, Air Products, will run a two-year demonstration program for hydrogen-powered forklifts at the Defense Logistics Agency. The program will create an indoor hydrogen fueling station infrastructure to fuel 20 hydrogen-powered forklifts for daily operations at the Defense Distribution Susquehanna Pennsylvania (DDSP) warehouse. Air Products is collaborating with General Hydrogen to retrofit battery-powered forklifts with fuel cell power packs and provide fueling stations.
DDSP personnel will operate the fuel-cell forklifts alongside lead-acid battery forklifts in daily operations. DDSP will gather data to compare costs and operational characteristics. The data will be used to support the development and commercialization of hydrogen fuel-cell technologies for Dept. of Defense operations.
Hydrogen-powered forklifts need refueling once or twice daily. The process typically takes less then five minutes. By contrast, battery-powered forklifts must be taken out of operation for battery replacement or recharging every four to six hours. “We believe the program will demonstrate that hydrogen-powered forklifts will show productivity improvements during active warehouse operations while also showing economic and environmental benefits,” says Tom Joseph, business development manager for Hydrogen Energy Systems at Air Products.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
