The largest share of oil products is used as " energy carriers ", i . e . various grades of fuel oil and gasoline.
33.
For example, at a metal-metal interface, electron scattering effects will dominate thermal boundary resistance, as electrons are the primary thermal energy carriers in metals.
34.
"' World Hydrogen Energy Conference "'( WHEC ) is a series of international events covering the complex issues of utilizing hydrogen as an energy carrier.
35.
However, the energy density of hydrogen is considerably higher than that of electric batteries, making it a serious contender as an energy carrier to replace fossil fuels.
36.
Finding a more efficient way to transfer heat to electricity ( or maybe hydrogen or other energy carriers ) would be a major step forward for mankind.
37.
The article hydrogen economy states . " As an energy carrier, hydrogen could substitute for dwindling supplies of petroleum and provide energy independence to countries without oil resources ."
38.
The draft budget should not become " hostage to foreign energy carriers'prices " and it needs to be protected as much as possible from external economic factors, Putin said.
39.
Besides car batteries however, other Grid energy storage projects make use of less polluting energy carriers ( e . g . compressed air tanks and flywheel energy storage ).
40.
Since high-exergy energy carriers can be used in for more versatile purposes, due to their ability to do more work, they can be postulated to hold more economic value.
