One exception to note: If the food's sitting in an environment where the temperature is over 90Â°F, the USDA says the food should only be left out for one hour, so keep an eye on the clock if you're serving food on a hot day!
Estimated cost of hydrogen per kilogram in a variety of scenarios. With all of this in mind, here are the cost estimates per kilogram (which each include $1.25 for taxes): Hydrogen from natural gas (produced via steam reforming at fueling station). $4 â $5 per kilogram of hydrogen.
3 The costs of compressing, storing, and dispensing (CSD) hydrogen are adjusted from $1.88/kg H 2 in 2005 dollars to $2.00/kg H 2 in 2007 dollars using the U.S. Macroeconomic Indicators and Carbon Dioxide Emissions table.urrent wind incentivesâsuch as the Production Tax Credit (PTC), Investment Tax Credit (ITC), and Treasury Grantâcan reduce hydrogen costs approximately $1/kg and are crucial to meeting DOE cost targets.
