QUESTION5 A composite storage container has 28 liters of internal volume and has a mass of 57 kg. The hydrogen is stored at 700 Bar and 25°C. Using the LHV for hydrogen, determine the specific energy of this storage container. Use a compressibility factor Z 1.45 0.3 kWh/kg 0.63 kWh/kg 0.7 kWh/kg 2.3 kWh/kg QUESTION 6 Chemical hydrides O are much heavier than metallic hydrides O release hydrogen gas via a chemical reaction (usually with water); byproduct can be regenerated separately. O are a laboratory experiment with no practical application. O are unstable at room temperatures and therefore only suitable for aerospace applications

Explanation / Answer

6) Chemical hydrides release hydrogen gas via chemical reaction with water . The byproduct can be regenerated seperately. they are used to store and deliver hydrogen gas to fuel cells. They have high native hydrogen content, and hydrogen can be released by several chemical pathways.
