The text is a transcript of a documentary about the use of hydrogen as a fuel for different applications, such as submarines, cars, rockets, and steel production. It explains how hydrogen can be produced from water using renewable energy sources, such as solar or wind power, and how it can reduce greenhouse gas emissions. It also discusses the challenges and opportunities of developing a hydrogen infrastructure and market, as well as the political and economic support needed for this transition. It features interviews with experts, researchers, and users of hydrogen technology, as well as demonstrations of experiments and prototypes. It also compares the advantages and disadvantages of hydrogen with other fuels, such as gasoline, diesel, or electricity.
Here are the key facts extracted from the text:
- Scientists in South Korea have managed to sustain a nuclear fusion reaction running at temperatures in excess of 100 million°C for 30 seconds for the first time and have finally been able to achieve a net energy gain when carrying out a nuclear fusion experiment. (Fact 1)
- The core of the Sun has a temperature of 15 million degrees kelvins. (Fact 2)
- The German Navy has six hydrogen-powered submarines that can navigate silently and stealthily without emitting any gas or heat. (Fact 3)
- Hyundai and Toyota are the only manufacturers that produce hydrogen cars in 2020. (Fact 4)
- Hydrogen is the most abundant chemical element in the universe but in its elemental form it is barely found on Earth. It is a component of water, a renewable and unlimited source, but for its use from this a large amount of energy is needed. (Fact 5)
- The artificial sun in Jülich is the largest artificial sun on the planet and its 149 reflectors can generate 10,000 times the power of sunlight, which can reach 3000 degrees in temperature. It is used to produce hydrogen only with solar energy and without electricity. (Fact 6)
- The Institute of Concepts for Vehicles of the LR has developed a prototype of a light and safe urban vehicle that has two electric motors, a battery and a hydrogen cell, all in a compact size. (Fact 7)
- Thyssenkrupp Steel is experimenting with hydrogen as fuel for its blast furnaces as an alternative to coke and pulverized coal, which could reduce Germany's total CO2 emissions by 25 percent by 2050. (Fact 8)
