+A suggested alternative use is as a working gas for a [[Stirling Engine]], where it can achieve a conversion efficiency of 18%, surpassing the efficiency of [[Methane]] and tying it with [[Helium]].
 Hydrogen also has the lowest freezing point of all gases capable of phase change, making it the only choice for extreme cryocooling applications. However, its limited latent heat capacity hinders its performance in that task.

		+	== Description ==
		+	<blockquote><q>Hydrogen is the most efficient fuel by weight for rocketry. When mixed with [[Oxygen]] it will cleanly combust into [[Water\|Steam]].</q><br>
		+	'''- Stationpedia'''</blockquote>
		+
		+	'''Hydrogen''' or '''H<sub>2</sub>''' is a combustible gas. The main source of Hydrogen on most planets is in the form of [[Ice (Volatiles)]] that can be mined on the surface. Hydrogen will autoignite at 300°C or above in the presence of [[Oxygen]], autoignite at 150°C in the presence of [[Ozone]] and autoignite at 50°C in the presence of [[Nitrous Oxide]].
		+
		+	=== Combustion ===
		+	* 2 mol H2 + 1 mol O2 = 3 mol H2O + 612 kJ (autoignition at 300°C)
		+	* 1 mol H2 + 1 mol N2O = 1 mol H2O + 1 mol N2 + 612 kJ (Autoignition at 50°C)
		+	* 3 mol H2 + 1 mol O3 = 4 mol H2O + 1836? kJ (Autoignition at 150°C) <!--Stationpedia equation is not balanced, check actual combustion code later-->
		+
		+	== Usage ==
		+	''See also: [[Fuel]]''
		+
		+	While Hydrogen is a superior fuel for rocketry, there is currently no way to refine it from [[Methane]], limiting its available supply. As such, it is recommended to combine it with [[Nitrous Oxide]] or [[Ozone]] in rocketry applications to maximize its effectiveness.
		+
		+	A suggested alternative use is as a working gas for a [[Stirling Engine]], where it can achieve a conversion efficiency of 18%, surpassing the efficiency of [[Methane]].
		+
		+	===Notes===
		+	* The Specific heat of 20.4 Joule / mol is in-between the specific heat of Hydrogen and Methane in real-life.
		+	* The actual Autoignition temperature of Hydrogen in Oxygen is approximately 570 °C at 1 atm, decreasing to 414°C at 7.4 MPa.
		+	* Unlike [[Methane]], Hydrogen is not toxic to most plants in-game.
		+	* As far as rocketry is concerned, Volatiles have a mass of 500 mol/kg.
