## What is the calorific value of petrol and hydrogen?

## What is the calorific value of petrol and hydrogen?

The heating value of gasoline is 47 megajoules per kilogram, while that of hydrogen is 143. The heating value of hydrogen, and thus its energy density, thus beats that of gasoline by about three times.

## What is the calorific value of petrol and diesel?

Diesel and petrol engines The calorific value of diesel fuel is roughly 45.5 MJ/kg (megajoules per kilogram), slightly lower than petrol which is 45.8 MJ/kg. However, diesel fuel is denser than petrol and contains about 15% more energy by volume (roughly 36.9 MJ/litre compared to 33.7 MJ/litre).

**Which fuel has highest calorific value?**

Hydrogen

Answer: Hydrogen has the highest calorific value.

**Is calorific value of hydrogen is more than petrol?**

The amount of heat energy produced by the complete combustion of 1 kilogram of a fuel is called its calorific value (when it is expressed in joule/kg)….Which fuel has the highest calorific value? A.) Hydrogen gas. B.) Methane. C.) Wood. D.) Petrol.

Fuel | Calorific Value (kJ/kg) |
---|---|

LPG | 55000 |

Biogas | 35000-40000 |

Hydrogen | 150000 |

### What is calorific value of diesel?

The amount of heat energy produced on complete combustion of 1 kg of fuel is called its calorific value. Calorific value decides the efficiency of an energy source per unit weight. The Typical Gross calorific value of Diesel or HSD is 10800 Kcal/kg.

### What is the calorific value of hydrogen fuel?

120-142 MJ/kg

Also referred to as energy or calorific value, heat value is a measure of a fuel’s energy density, and is expressed in energy (joules) per specified amount (e.g. kilograms)….Heat Values of Various Fuels.

Heat value | |
---|---|

Hydrogen (H2) | 120-142 MJ/kg |

Methane (CH4) | 50-55 MJ/kg |

Methanol (CH3OH) | 22.7 MJ/kg |

Dimethyl ether – DME (CH3OCH3) | 29 MJ/kg |

**What is the calorific value of hydrogen?**

**What is the calorific value of hydrogen in kJ kg?**

1,50,000 kj / kg

Calorific value of Hydrogen is 1,50,000 kj / kg.

## Is hydrogen is an highest calorific value?

Hydrogen gas has the highest calorific value i.e., 150 kJ/kg, yet it is not used as a fuel.
