Hydrogen primary energy basis

The EU is inhabited by 15 percent of the total OECD and ERICS population and in this perspective the EU is especially well endowed with wind, wave/tide, and solar thermal electricity resources. Such renewable and non-combustible energy resources could form an indigenous primary energy basis for hydrogen. 

The basis for these non-photosynthesis based communities are bacteria that obtain energy from the oxidation of hydrogen sulfide escaping from the vents—a process called chemosynthesis. These bacteria (primary producers) are then used as foods by tube worms, huge clams, and mussels, and other organisms (primary consumers) living around the vents. These communities live in total isolation from photosynthetic-based communities (all other biological communities are photosynthesis based), and may provide clues to the nature of early life on Earth. Later studies have shown that hydrothermal vent communities exist in other parts of the ocean depths as well.
