NEA Recips Support Audi's Power-To-Gas Process: German technology converts electricity, CO_2 to methane

摘要

Neuman and Esser (NEA) has delivered three reciprocating compressors for German automaker Audi's project to produce 1102 tpy (1000 T/yr) of synthetic renewable methane (also called e-gas). Highly efficient storage media is required for wind power and photovoltaics. Renewable energy sources like wind and solar fluctuate with weather and seasonal variance, which can only be compensated using such storage. Another problem that occurs in the field of renewable energy is that the power grid is not prepared for the necessary, larger quantities of electricity distribution and transportation volumes.
