Hitachi Zosen Inova acquires assets of ETOGAS GmbH

Hitachi Zosen Inova (HZI) expands its renewable energy and biogas activities by the asset acquisition of German "power-to-gas" (PtG) specialists ETOGAS GmbH.

The Swiss company Hitachi Zosen Inova AG (HZI) has announced that it has acquired the assets of Stuttgart-based ETOGAS GmbH. The business operations, employees, patents, property rights, expertise, and related assets acquired, will be transferred to the newly established Hitachi Zosen Inova Etogas GmbH, based in Stuttgart, Germany.

The acquisition of the ETOGAS Power-to-Gas (PtG) technology follows previous HZI acquisitions of Kompogas and BioMethan. According to a statement, the deal enables HZI to expand its existing offering in the areas of thermal and biological energy-from-waste recovery and biomethane upgrading while open up new possibilities for PtG technology to enter international markets.

ETOGAS PtG tech

The developments in the energy sector call for flexible solutions to constantly and permanently ensure uninterrupted power supply and grid stability. According to HZI the ETOGAS PtG technology addresses power supply and grid stability by converting electricity into hydrogen using pressure electrolysis and methanation. By adding CO2 from biogas plants, the hydrogen is converted into carbon-neutral synthetic natural gas (SNG), which is fed into the existing natural gas grid. Volatile renewable energy is thus converted and made storable and transportable.

– With the acquisition of ETOGAS, we are addressing this trend of energy transition and setting a further milestone in the renewable energy supply sector. Considering our parent company’s existing technology portfolio, which among others includes the electrolyzer and catalyst technologies, we believe this acquisition accelerates the group synergies in PtG business, said Franz-Josef Mengede, CEO, HZI.

According to Gregor Waldstein, founder of ETOGAS, the sale was made for strategic reasons. As a start-up firm, ETOGAS was able to establish primarily in the German market. International markets, however, have remained largely untapped. HZI as parent company will provide the necessary marketing, distribution network and other synergies for entering these markets while also ensure the continuation of the ETOGAS location in Stuttgart.

– We are convinced that the technological and specialist expertise of ETOGAS will be developed further as part of HZI, and that it will continue to grow as a key area of the company, stressed Waldstein.

World’s largest and first industrial PtG plant

ETOGAS has built the world’s largest and first industrial Power-to-Gas plant with 6.3 MW input power on behalf of Audi AG in Werlte, Germany. The plant has been producing Audi’s e-gas since 2013 in dynamic and intermittent operation using wind power and CO2 from a biogas plant. The renewable synthetic natural gas (SNG) is fed into the natural gas transmission network on-site. The PtG plant recycles around 2 800 tonnes of CO2 per annum and the conversion efficiency from electricity to gas is according to ETOGAS approximately 54 percent.

– The ETOGAS technology serves as a key component in the energy transition process. We are convinced that with the construction of the Audi e-gas facility in Werlte, we have made an investment in the energy supply of the future, said Reiner Mangold, Head of Sustainable Product Development at Audi AG.
