Abstract

A composition comprising a carrier liquid; a dispersant; and a chemical hydride. The composition can be used in a hydrogen generator to generate hydrogen for use, e.g., as a fuel. A regenerator recovers elemental metal from byproducts of the hydrogen generation process.

Claims

1. A method of operating a hydrogen-fueled device, the method comprising conveying hydrogen released from a composition to the device, the composition comprising a carrier liquid, a dispersant, and a chemical hydride, wherein the dispersant comprises a triglyceride.

2. The method of claim 1, further comprising contacting the composition with water.

3. The method of claim 1, further comprising removing water from the hydrogen released from the composition.

4. The method of claim 1, further comprising controlling a reaction temperature from the release of the hydrogen.

5. The method of claim 1, further comprising conveying water from the device to a water reservoir.

6. The method of claim 1, further comprising separating the hydrogen from a hydroxide product.

7. The method of claim 1, further comprising pumping the composition to a reactor.

8. The method of claim 1, wherein the carrier liquid comprises mineral oil.

9. The method of claim 1, wherein the triglyceride comprises triolein.

10. The method of claim 1, wherein the chemical hydride comprises magnesium hydride.

11. The method of claim 1, wherein the chemical hydride comprises lithium hydride.

12. The method of claim 1, wherein the the carrier liquid comprises mineral oil, the chemical hydride comprises magnesium hydride, and the triglyceride comprises triolein.

13. The method of claim 1, wherein the composition comprises about 50 to about 75% by weight of the chemical hydride.

14. The method of claim 1, wherein the device is a fuel cell.

15. The method of claim 1, wherein the device is a combustion engine.
