ETOGAS drives the commercialization of Power-to-Gas and is the market and technology leader. ETOGAS is the pioneer of Power-to-Gas (PtG). Power-to-Gas is a disruptive technology for building a smart energy ecosystem based on renewable sources. ETOGAS addresses three segments in global emerging markets: Renewable fuels, Industrial, Renewable Electricity. With three product segments based on ETOGAS technology,
we address five different customer benefits. ETOGAS offers a complete scope of services and a proprietary technology portfolio: water electrolysis and methanation technology as well as system integration including BoP components. Modular design is basis for all our products – ETOGAS electrolyzer is the central building block. ETOGAS acted as turnkey supplier in charge of design, installation and ramp-up of the
world’s largest industrial Power-to-SNG project to date. The Audi e-gas plant was designed and built by ETOGAS - and demonstrates that alkaline
electrolyzer technology can follow dynamic loads and provide balancing power. The 1.2 MW PtSNG plant with proprietary technology is based on modular building blocks, has a
cost-optimized BoP solution and is capable of directly using raw biogas as a CO2 source. Power-to-SNG product overview. In 2014, ETOGAS launched its proprietary Power-to-Hydrogen technology and has won the leading gas storage operator RAG as a reference customer. Power-to-Hydrogen (PtH2) product overview.

What is Power-to-Gas?
A disruptive technology for building a smart energy ecosystem based on renewable sources
• PtG allows the conversion of volatile electricity into renewable,
synthetic gases (H2 or SNG) with unmatched low carbon
footprint, which
– can be stored, transported and commercialized
– for mobility (green synthetic fuels) and industrial markets
(green chemistry).
• PtG adds flexibility to energy systems and thus enables efficient
integration of high shares of volatile renewables into energy
markets at low costs.
PtG facilitates this by
– creating a connection between the power grid and the gas
grid with its ample storage and transport capacity;
– recharging the gas grid without timing / technical restrictions and
thus allows to generate electricity at some point of time
somewhere and to sell it in the form of synthetic fuel
anywhere and anytime.
Concept
• Conversion of electricity into gaseous energy carriers (hydrogen,
methane).
• Starts with electrolysis, the disaggregation of water into hydrogen
(core product) and oxygen (by-product) by applying an electric
current to water.
• Methanation, the optional second PtG process step, is an
exothermal chemical reaction, which transforms the hydrogen with
injected carbon dioxide into methane (synthetic natural gas,
“SNG”).
