Abstract

The conc s response to the first oil crisis. In the context of the hydrogen economy, it is important to calculate how much hydrogen would be needed to power all motor vehicles in the Czech Republic. This is main topics of this paper. To calculate the amount of hydrogen, we used two different methods. One is based on thermodynamic laws and the other on normal operating conditions. Both approaches yielded comparable results. It was found out that even with the use of all the electricity produced in the Czech Republic in 2016, we would not be able to cover the amount of energy that is required for production. It would cover only 75% resp. 76% depending on the calculation method used. Eventually, the Czech Republic could buy necessary amount of hydrogen and it would cost between 11 and 29 billion euros which is between 6% and 16% of GDP of the Czech Republic. In the calculations, authors found out that most fuel is burnt in the passenger cars. Therefore, we made a sensitivity analysis to find out how much our results would differ if fuel consumption changed. It turns out that with an increase in consumption of 1l per 100 km, hydrogen production coverage will decrease by about 4% (again with the use of all electricity produced in the Czech Republic).

捷克共和国氢燃料的能量分析

这是对第一次石油危机的反应。在氢经济的背景下，计算捷克共和国需要多少氢来为所有机动车辆提供动力是很重要的。这是本文的主要课题。为了计算氢气的数量，我们使用了两种不同的方法。一种是基于热力学定律，另一种是基于正常运行条件。两种方法都产生了相似的结果。我们发现，即使使用2016年捷克共和国生产的所有电力，我们也无法满足生产所需的能源。它将只覆盖75%的份额。76%取决于使用的计算方法。最终，捷克共和国可以购买必要数量的氢气，这将花费110亿至290亿欧元，占捷克共和国GDP的6%至16%。在计算中，作者发现大部分燃料是在乘用车中燃烧的。因此，我们做了一个敏感性分析，以找出如果燃料消耗改变，我们的结果会有多大的不同。事实证明，随着每100公里消耗增加11个，氢气生产覆盖范围将减少约4%(再次使用捷克共和国生产的所有电力)。
