Which of the following statements is/are correct? 1. The National Hydrogen Energy Road Map was prepared by the Steering Group on Hydrogen Energy under the Chairmanship of Shri Ratan N. Tata.

1. Hydrogen has the highest energy-to-weight ratio of all fuels.

Statement 1 is correct: The National Hydrogen Energy Road Map was prepared by the Steering Group on Hydrogen Energy, set up in 2004, under the Chairmanship of Shri Ratan N. Tata. Statement 2 is correct: Hydrogen is the lightest element occurring in nature and contains a large amount of energy in its chemical bond. Because of its low density, liquid hydrogen weighs less than petroleum-based fuels. The density of gaseous hydrogen is 0.0899 grams per liter (g/l). (Air is 1.4 times as dense.) Liquid hydrogen boils at -252.77 degrees Celsius, and it has a density of 70.99 g/l. With these properties, hydrogen has the highest energy-to-weight ratio of all fuels.
