The way to GoBiGas

The idea to develop a method for large-scale production of biogas was born at Göteborg Energi in 2005. Since then we have consciously worked ahead further towards developing the technology and plan for a large-scale production plant in Gothenburg.

Around 300 people are now on the site. Apart from these, there are around 100 people in place that are stationed in barracks throughout the construction site.



GoBiGas Phase 2 is one of the three Swedish renewable energy projects that become granted support under the EU's NER 300 program. This is one of the world's largest funding program for renewable energy.

The third film in the series about GoBiGas made.

GoBiGas receives the remaining 25 million out of the total 222 million project, which was granted by the Swedish Energy Agency.

Several recruitments are made. All operation technicians are employed and many of these are already on site.

October 2012

The first engineer is recruited internally. New advertisements are carried out to employ the remaining four operation technicians.

The compressor, which was the first piece of equipment that was ordered, is assembled on site.

September 2012

Eight technicians and an operations manager are hired. Also two technicians and one operations manager are recruited from within the company.

From April to September, GoBiGas gets visited by several field trips. More than 500 people, both external and from Göteborg Energi, during this period, visited the plant.

GoBiGas has a reference plant for gasification which is half the size of GoBiGas facility and located in Senden, Germany. The plant in Senden is during startup and allows functionality evaluation and any necessary modifications to GoBiGas can be done before the system is started up. The project organization visits the plant in Senden during week 37 to conclude that operation runs well, but that some fine tuning has to be done.

August 2012

Currently there are around 50 people working with the assembly work on site.

Connections for cooling water, city water and natural gas are implemented.

 July 2012

Installation of equipment in both gasification part and methanation part of the plant.

A status report on GoBiGas stage 1 is sent to EU. For the other major projects that received grants from the so-called Climate Billion the deadline has expired. This makes GoBiGas the only project among these that has become reality. Göteborg Energi has thus obtained the largest state grant paid in Sweden.

Åsa Burman participates in Almedalen in a debate on larger scale biogas ventures.

 June 2012

The gasifier, which is a central part of GoBiGas, arrives by sea from the manufacturer in Germany. Metso is now able to start constructing the gasification section.

Contracts are signed with Swedegas regarding entry and transfer of biogas production on their high pressure grid.

Second film about GoBiGas is recorded.

The project is involved in inspections and functional testing of critical equipment at suppliers.

May 2012

The base and walls of the process building are completed and the building of the steel structure is started.

Metso Power establishes on site.

Swedegas obtains planning permission for the establishment of a compressor station for discharging produced gas to the national gas grid.

The first film about the project is completed.

April 2012

The municipality and City Council finalizes the decision on implementation of GoBiGas Stage 1.

The first internal and external study visits take place on site.

 Mars 2012

Several major procurements of equipment and control systems are implemented during the period.

There is a contract negotiations with Swedegas concerning the supply of gas on the main gas network.

Åsa Burman participates in a meeting in Stockholm about Swedish bioenergy and bio projects which the British Embassy has arranged for Prince Charles.

February 2012

A number of security measures are implemented on the already existing Rya Hot Water Central. These are made to reduce health and safety risks when installing GoBiGas plant.

The project is negatively highlighted in both local newpaper GöteborgsPosten and TV program Uppdrag Granskning.

January 2012

After a long dialogue about alternative forms of cooperation E.ON decides not to continue the discussion.

Ground preparation is completed according to plan and moulding of the base and walls of the process building starts. Procurement continues for both contracts and equipment. A lot of equipment is also in production.

December 2011

The board of Göteborg Energi decides to expand the investment budget for the GoBiGas project and also to extend the schedule.

Local newpaper GöteborgsPosten publishes a few negative articles about GoBiGas project, both before and after the Board meeting. During the same period several positive debate articles are published.

June-November 2011

During Almedal week, which is hold on Gotland in July, Åsa Burman paricipates as speaker and panelist.

The layout of methanation has to be adjusted several times, partly because the detailed risk analyzes require relocation of equipment and partly because the equipment takes up more space than was previously estimated. Building area must therefore be extended and new building permits need to be applied. Another consequence is that the project cost increases and schedule shifts.

During this period efforts are continuously made to find solutions to reduce costs while still maintaining performance and safety.

All claims for payment from Swedish Energy Agency's payment are fullfilled, and in October 90 percent of the grant is paid.

Throughout this period the City of Gothenburg continues investigations on GoBiGas among others.

 May 2011

The first equipment - a gas compressor with long delivery time - is purchased.

The City of Gothenburg starts an investigation on several projects within the municipality, including GoBiGas.

April 2011

Contract for engineering, procurement and construction management of the methanation and building and auxiliary systems is signed with Jacobs Process in Holland.

January 2011

Implementation starts as the groundwork starts in Rya Harbor.

December 2010

EU Commission approves state aid to the GoBiGas Project.

The Göteborg Energi board makes a final decision for the investment for implementation of the GoBiGas project phase 1.

September 2009

Phase 1 of the GoBiGas Project is chosen as one of the total of five projects receiving subsidies from the Energy Agency, on the condition that the state aid is approved by the EU-commission.


Pre-project planning of the proposed technique for phase 1 takes place. Project development occurs in cooperation with E.ON.


Advanced studies of varying gasification techniques are implemented. The choice is made for indirect gasification with techniques from Austrian company, Repotek, based on, among other things, performance and reliability.


Göteborg Energi implements a feasibility study to compare the technology and financials for the two gasification techniques: indirect gasification and pressurized oxygen-blown gasification.


A preliminary feasibility study starts with respect to the possibilities with gasification.

"We must both protect the climate and continue to be able to transport ourselves. The fact that Sweden is investing in the development of biofuel for future generations is therefore very important. It contributes to the reduction of the climate impact of the transport sector”, says Minister of Industry, Maud Olofsson."
