Today’s situation
- Not green.
- Expansive to transport.
- 65%-80% energy efficienct of the production.[2]
- 100 billion dollars industry.[1]

H2 as a FUEL

What is our goal?
- Reduce greenhouse gas emissions.
- Make it transportable and storeable.
- Produce H2 cheaply.

Our methodPlants → Sugar Sugar + Enzyme→ Hydrogen[4] →H2+ Sugar mixture → Safe!
![Page 10: Hydrogen Production: creating an efficient industry. Liora Berkovich, Jannik Fritz, Guillem Rivas, Hagai Shechter.](https://reader036.fdocuments.us/reader036/viewer/2022062713/56649cc25503460f94989634/html5/thumbnails/10.jpg)
Step 0: Harvesting - 2500$ for 1 hectare (10,000 m2) of
salicornia bigelovii (plant).
- Total 2.5 tonnes of seeds per hectare.
- 20 tonnes of hydrogen per hectare approximately.

1st Step - extracting sugar
- Seperate lignin from cellulose to obtain sugar.
- 92% of the mass of the plant is sugar.
- 26% of the sugar is xylose.
![Page 12: Hydrogen Production: creating an efficient industry. Liora Berkovich, Jannik Fritz, Guillem Rivas, Hagai Shechter.](https://reader036.fdocuments.us/reader036/viewer/2022062713/56649cc25503460f94989634/html5/thumbnails/12.jpg)
2nd Step - producing hydrogen
combine xylose with enzymes at 50 Co
rate of production: 1.95 mmol/h/l
after 20 hours: 9.5 mol/1mol of xylose
![Page 13: Hydrogen Production: creating an efficient industry. Liora Berkovich, Jannik Fritz, Guillem Rivas, Hagai Shechter.](https://reader036.fdocuments.us/reader036/viewer/2022062713/56649cc25503460f94989634/html5/thumbnails/13.jpg)
C5H10O5 + 5H2O→10H2 + 5CO2
13 enzymes needed
ratio between CO2 and H2 is 1:2
![Page 14: Hydrogen Production: creating an efficient industry. Liora Berkovich, Jannik Fritz, Guillem Rivas, Hagai Shechter.](https://reader036.fdocuments.us/reader036/viewer/2022062713/56649cc25503460f94989634/html5/thumbnails/14.jpg)
3rd Step - storing hydrogen- Hydrogen is mixed with
starch, making it solid.
- Enzymes are used to seperate them again.
- 1kg of starch contains 200g of H2
![Page 15: Hydrogen Production: creating an efficient industry. Liora Berkovich, Jannik Fritz, Guillem Rivas, Hagai Shechter.](https://reader036.fdocuments.us/reader036/viewer/2022062713/56649cc25503460f94989634/html5/thumbnails/15.jpg)
Application in the industry
5.64kg H2 to drive 600km
A tank capacity 30kg of starch & H2
![Page 16: Hydrogen Production: creating an efficient industry. Liora Berkovich, Jannik Fritz, Guillem Rivas, Hagai Shechter.](https://reader036.fdocuments.us/reader036/viewer/2022062713/56649cc25503460f94989634/html5/thumbnails/16.jpg)
Comparison of costsH2 production by steam reforming
H2 production by sugar.
costs between 3-5$ (depending on purity)
enzymes for separation: 0.03-0.05$+production costs of H2: 0.05$+construction costs, distribution, etc.: ca. 0.75$------------------------------------------------= 1$ maximum instead.

Conclusion- cheaper hydrogen.
- 100% pure hydrogen.
- a greener production.
