How to store energy -2
Hydrogen exists in gasous form in the standard condition due to its quite low boiling point, meaning that it is difficult to store and transport. This drawback, however, does not lead to a conclusion of giving up the use of hydrogen, because hydrogen also has another strong benefits in its production and usage. Hydrogen and its derivative are to be discussed in the series of posts, by considering "how small the volmetric energy density can become".

Hydrogen as an energy carrier?
Renewable electric power is converted into energy carrier for storate or transportation. The energy carrier preferably contains "large amount of energy" in "small volume, small weight". What is the most suitable material for the energy carrier? A close look at the periodic table may point to hydrogen, located at that top-left corner. This posts discusses the characteristics of hydrogen as an energy carrier.
Issues associated with renewable energy utilization
The expantion of renewable energy utilization is now a common theme globally. However, just keeping to increase installation of renewable energy facilites woud not achive the sustainable circulation of enregy in our society. This post addresses the gap in locations for electric power generation and usage.
The amount of energy we consume
Human being relies on energy in daily life. Our lives cannot be described without mentioning energy. Have you ever considered how much of energy we consume?
Energy conversion involved in generation of electric power
The process of electric power generation converts the form of energy, from that of fuels, into electric power. This post summarizes the forms of enregy involved in such processes.
What determines the characteristics of fossil fuels?
When using the fossil fuels or hydrogen as an energy source (e.g., by combusting them to obtain heat), we extract their chemical energy. And, the chemical energy is stored in chemical bonds. Therefore, in so doing, we arrange the bonding of fuel, to obtain the difference of energy stored in reactants and products (see more […]
How much of energy can be extracted from fossil fuels?
The fossil fuels have been extensively utilized in our society, because they are extremely rich in energy (see Why we rely on fossil fuels?). This post tries to address, then, how much of energy do the fossil fuels possess? The type of energy that fossil fuels have is "chemical energy", which is stored in chemical […]
Why we rely on fossil fuels?
Our society has been relying on fossil fuels such as oil, natural gas, and coal. Why have we relied so much on these fossil fuels?
