A method and apparatus 10 for densifying liquid methane is described. The method includes passing the liquid methane through a liquid nitrogen bath 14, self-pressurizing a container 62 associated with the liquid nitrogen bath through boil off of the liquid nitrogen within the container, and regulating pressure within the liquid nitrogen container to maintain a boiling point of the liquid nitrogen above the triple point temperature of the liquid methane passing through the liquid nitrogen bath. The method and apparatus or system is particularly suitable for reducing the volume of fuel to be carried by a space vehicle or lunar lander. |
