High-temperature decomposition
High-temperature splitting of water occurs at about 3000 °C. At this temperature, 10% of the water is decomposed and the remaining 90% can be recycled. To reduce the temperature, other processes for high temperature splitting of water have been suggested:
▸Thermo-chemical cycles.
▸Hybrid systems coupling thermal decomposition and electrolytic
fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments are trying alternative energy is concern about pollution and climate change caused by the use of fossil energy.
So, we needed an alternative source of energy for our own good.
Also, we called for investm

->화석연료는 석탄이나 석유등의 자원을 이용하여 에너지를 얻은 것을 말하며 동식물의 유해의 오랜 시간의 퇴적의 결과로 얻어진다. 오랜 시간에 걸쳐서 화석화 하면서 그 속에는 질소가 포함되어 있다.. 이러한 질소가 화석연료를 사용할 시 대기 중으로 방출되게 된다.
