REGATEC 2020 – a hotspot for the biogas, gasification and P2G community

7th International Conference on Renewable Energy Gas Technology, REGATEC 2020 is in good progress.

The conference takes place 20-21 September 2021 in Weimar, Germany and is organised in collaboration with the Thuringian Energy and GreenTech Agency, ThEGA. As a result of the cooperation all biogas operators in the federal state of Thuringia are invited to participate in the exhibition free of charge.

The latest advances within biomethane, bioSNG and electro-methane will be highlighted by 60+ leading experts in oral and visual presentations. G-mobility, LBG, power-to-gas and its synergies with anaerobic digestion and biological methanation of syngas are high on the agenda. Experiences from several first-of-a-kind industrial scale gasification, anaerobic digestion and power-to-gas facilities will be presented.

REGATEC 2020 is sponsored by Air Liquide, Arcanum Energy, Azola, Baltic Energy Innovation Centre, BMF HAASE GmbH, Cortus Energy, Electrochaea GmbH, Landwärme GmbH, microbEnergy GmbH, Richter ECOS GmbH and Storengy.

Renewtec visits Cryostar

On the 28th of October Renewtec visited Cryostar SAS in Hésingue just outside Basel.

SDC12730Jörgen Held, Renewtec together with Bruno Brethes, Executive Director, Business Unit Clean Energy, Cryostar SAS.





Cryostar SAS is a supplier of small scale natural gas (and biogas) liquefaction plants. The smallest unit has a capacity of approx. 20 tonnes/day.

The technology relies on the principles of a closed refrigerant cycle (nitrogen) to produce the Cold Power needed to condense the natural gas or biogas.

SDC12724All the machinery is assembled and tested in Hésingue before deliverd to the customer. The tests are performed with air or liquid nitrogen.




Cryostar provides liquefaction plants, truck loading stations and vehicle fuel LNG stations. At the moment 40 stations delivered by Cryostar are in operation. Cryostar has working relation with providers of polishing units which is a need when liquefying upgraded biogas. As a subsidiary of the Linde Group services for distribution of LNG and LBG can be included.

SDC12729Cryostar SAS has one of the largest testing facilities for cryogenic pumps in the world. The icing of the pipes is due to the moisture in the air freezing on to the cold parts.




Since a cryogenic pump requires much less electrical energy than a compressor L(C)NG stations are of great interest. Such stations are able to provide both LNG and CNG. The LNG is pressurized with the pump. When heated through a heat exchanger the high pressure liquid turns into compressed natural gas. The same goes for biogas, of course.
