The era of fossil fuels is ending. What will replace them and reshape the world's energy-scape?
Solar, hydro, nuclear, bio and hydrogen are just a few fuels mentioned. Against this backdrop, a book betting on hydrogen has just hit the shelves.
"Hydrogen Society," co-written by five journalists at Money Today, a business daily here, explains why humans will end up relying on hydrogen more than other energy sources.
First, hydrogen is the most abundant chemical substance in the universe, constituting roughly 75 percent of all baryonic mass. This will allow virtually "everlasting" use of hydrogen as a key energy source and eliminate the grounds for diplomatic/military conflict over energy supply, said the book.
Second is its eco-friendliness. The only "waste" from hydrogen-fueled power generation is water.
Third is safety. The book explains why hydrogen container explosions are all but impossible.
Low efficiency in hydrogen collection, compression and hydrogen-to-electricity conversion are among issues that need to be tackled. But the book said it is just a matter of time before hydrogen takes up the present position of fossil fuels because technologies evolve and, above all, major economies are recognizing the value and potential of hydrogen.
The 184-page book is based on the reporters' extensive interviews with leading experts, industry insiders and policymakers at home and abroad. It also offers up-to-date information about what's happening in South Korea, the United States, China, Japan and Europe.
Money Today published the book. It is priced at 15,000 won.
