Anna discusses the recent testing of a hydrogen train in the Netherlands. She explains that hydrogen is the simplest element and its potential as a clean energy source. Anna delves into hydrogen production methods, mentioning electrolysis and fossil fuels, highlighting the importance of green hydrogen production. She compares the energy efficiency of hydrogen and electric cars, emphasizing that hydrogen may be more suitable for heavy transport. Anna addresses safety concerns related to hydrogen, comparing its flammability to gasoline. In conclusion, she suggests that while hydrogen has advantages, electric cars remain a preferable choice for most passenger vehicles.
1. This month, for the first time in the Netherlands, a hydrogen train was tested on the route between Groningen and Leeuwarden using sustainable green hydrogen from Groningen .
2. This hydrogen train can travel at approximately 140 kilometers per hour .
3. Hydrogen is the simplest, sweetest, and most common element in the universe .
4. It is present in about 92 percent of the sun and about 10 percent of our body weight .
5. Hydrogen does not occur as a separate gas on earth, but is part of a larger molecule .
6. When combined with oxygen, hydrogen can form water (H2O), and with carbon, it can form hydrocarbons such as methane .
7. There are a number of methods to extract hydrogen, including electrolysis and extracting it from fossil fuels. However, these methods all cost energy .
8. Hydrogen has a high energy density, approximately 120 to 140 megajoules per kilogram, compared to gasoline's approximately 43 megajoules per kilogram and a good car battery's energy density without a mega .
9. Driving on hydrogen is more expensive and less efficient than driving electrically .
10. There is currently a lack of refueling infrastructure for hydrogen, with only a few places where you can refuel .
11. Hydrogen is safer than petrol when it catches fire, as it immediately goes up and does not form a puddle under the car .
12. Despite being theoretically a better option than petrol, hydrogen is less economical than electric driving .
13. Hydrogen is considered a good addition to electric driving, especially for heavier freight traffic .
