separation via a ceramic membrane (“thermo-physic cycle”).
▸Plasma-chemical decomposition of water in a double-stage CO2 cycle.
For these processes, efficiencies above 50 % can be expected and could possibly lead to a major decrease of hydrogen production costs. The main technical issues for these high-temperature processes relate to materials development for corrosion resist

고전경제학자들 중에서도 기술혁신이 경제적 진보를 가져온다는 논의를 전개한 사람들이 많다. 아담 스미스는 분업은 작업자들의 전문화된 발명을 유도
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
hydrogen energy, tidal energy and so on are researched with activity by scientists. Among them, hydrogen energy system supremely comes into the spotlight. Hydrogen energy system bases an ideal principle which hydrogen is produced from water and returns to the original substance; water after being used. We can expect that after 2010, the cost of hydrogen as one of the resources should be lower th
