The Bulgarian company OVERGAS Inc. AD is coordinating the project, which is the first Bulgarian project under the European Commission’s Research Fund for Coal and Steel.
The project consists in two steps, studying first the process of underground coal gasification (UCG) producing thereby streams of combustible gas (hydrogen, methane and CO₂) which can be extracted from the subsurface. Secondly, partners research on how to use the methane-rich gas stream to generate power in conventional turbines or fuel cells or for industrial heating and storing the CO₂ back into the rock from where the coal was extracted.
The idea of the study is to explore the potential and feasibility of utilizing deep lying coal seams (>1200m under the ground) of the target site in Bulgaria (and elswhere) for the UCG-CO₂ storage Scheme. Data from the target site will be used to model the complete process, incl. combustion, gas extraction and CO₂storage. They will pay particular attention to potential environment hazards, such as the chance of stored CO₂ leaking through cracks in the rock.
If proved to be applicable and effective the next stage could be a pilot test and extension to a semi-commercial scheme.

Recent attacks on Ukraine’s Zaporizhzhia nuclear power plant "mark the beginning of a new and gravely dangerous front of the war," the UN atomic agency's director general said last week.
After years of inaction, Germany is working on its Carbon Management Strategy to resolve how CCS can play a role in climate action in industry. At the end of February, the Federal Ministry for Economic Affairs and Climate Action published first key points and a proposal to amend the law Kohlenstoffdioxid Speicherungsgesetz (KSpG). Bellona Deutschland, who was actively involved in the previous stakeholder dialogue submitted a statement in the association hearing.
In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
