POWER TO GAS: DESIGNING A PILOT PLANT FOR USING SOLAR ENERGY TO PRODUCE FUEL

Abstract

Power to gas (PTG) is the process of converting surplus power into another form of energy. Power-to-gas is the functional description of the conversion of electrical power into a gaseous energy carrier like e.g. hydrogen or methane. This technological concept considered as an interesting tool in the energy transition. The most common form is the hydrogen gas. Hydrogen considered as an energy carrier that produced by several methods. The most common method is the steam gas reforming process that uses natural gas as a feedstock to produce hydrogen. The other method is the water electrolysis process, which is the decomposition of water molecules into hydrogen and oxygen using solar energy. The produced hydrogen injected directly to the natural gas grid with specific limit in transmission or in distribution pipelines. As a result, power-to-gas enables the share of renewables in the energy mix to increase, making this innovation an important topic in achieving a carbon-neutral gas supply in 2050.
