From the optimization of energy usage in our facilities and implementation of green project rules through to the building of towers for bats: we are involved and dedicated at many levels to improving the ecological balance of underground natural gas storage.

Our Contribution to the SDGs

With targeted environmental activities, we are working to help achieve sustainable development goals 13 & 15.

We Never Stand Still

The compressors at our Bad Lauchstädt and Bernburg facilities are our greatest energy consumers. By combining the two locations into one storage zone, we’ve been able to use them synergistically, and cut electricity and gas use. We’re now compressing efficiently. 

We consciously chose to invest in efficient heating units for our Bad Lauchstädt facility. These will be installed at the end of 2021 following renovations, and will measurably reduce our co2 output going forward. The newest in condensing boiler technology improves efficiency while using fewer resources.

For Man, Flora and Fauna: Renaturalisation, Bats, Tree Sponsorships

While dismantling storage facilities in Buchholz and Kirchheilingen, we are working closely with environmental experts. We hope to create the best possible conditions for successful renaturation. Working with reforestation and soil care, we can ensure that plants and animals find what they need to live here. Should we ever need to disrupt nature again, we will balance this with voluntary initiatives. One example of this is what we’ve done in Kirchheilingen. Our outdated control room building had also long served as a home for bats. When we had to demolish it, we created a replacement habitat in the form of a six-meter tower with special openings. Our facilities are very green in general and provide nesting possibilities for many types of birds. With our contribution to the City of Leipzig’s tree-planting initiative "Baumstarke Stadt", we were able to take on a tree sponsorship program.

Energy-efficient Compression

Two locations, two energy sources, one synergy concept: the compressors at our Bernburg and Bad Lauchstädt locations are our largest energy consumers. One is an electric piston compressor, and the other a natural gas-driven turbo compressor. In combining the two sites into one storage zone, we can use them much more effectively. This combination allows for improved utilisation, even when working with low nomination volumes. The turbo compressors operate more often within their optimal ranges, and the gas needed for operation sinks. We are also able to better avoid counter currents meaning that the one location no longer needs to withdraw when injections are being done at the other. This means less low-volume storage operations and, finally, lower energy and gas consumption. 


Green Project Rules

Green from the beginning?
Ideally, yes – our green project rules take the ecological perspective into account during the earliest planning stages.
The goal: we want to significantly reduce or even totally avoid any potential adverse effects on the environment. When it comes to working in an environmentally conscious fashion, our project leaders serve as guides and models for our company and our partners. 


Ecological Decommissioning

The decommissioning of a location is a complex process. At the end of the process, we hope to have the most favourable conditions possible for successful renaturation. That’s why, as part of our green project rules, we involve environmental experts throughout planning and execution. They consider biological diversity and support the proper living conditions for both flora and fauna with actions such as reforestation and soil care management.
At our Kirchheilingen location, we were forced to destroy an old control room building, which had long been used by bats as a home. Before removing it, however, we consulted external ecological experts and created a replacement habitat for them in the form of a six-meter tower, including specially designed entrances. 

New Boiler Facility

Just as a new broom sweeps better, a new boiler facility heats better. Investment in efficient heating equipment means a higher degree of efficiency, less fuel usage, and significantly lower CO2 emissions. In 2018 and 2019, we renovated and improved energy efficiency in the boiler house at our Bad Lauchstädt facility. After the renovation of the technical components the most modern condensing boiler technology is in use. All pumps are equipped with frequency converters, allowing demand-based control. Inefficient pipe-bundle heating technology are also be replaced with trace-heating frost protection on the condensate tanks.


When affecting nature, we carry out voluntary protective measures and improvements. These are “stockpiled” using an eco-account. In this way, we were able to reforest 1.5 hectares of land with deciduous trees. This is one example of our efforts to compensate - across various projects - for future changes to the landscape.



Our overall goal, standing above any other sustainability measures, is the minimization of carbon dioxide emitted by our operations. On our path to this goal, we have already implemented climate-neutral storage and developed various green products as part of our enhanced portfolio.

But we are nowhere near finished. We are continuously working to analyse our CO2 footprint and further improve upon our green indicator systems.



Safety, health, quality, and environment – these are the supporting columns of our internally developed management system, integrated and certified since 2014.

Our Standards

In October 2020, we were re-certified according to the following norms: 

  • ISO 9001:2015 – Quality Management
  • ISO 14001:2015 – Environmental Management
  • ISO 45001:2018 – Safety Management

Into VGS’s management system are currently the requirements of DIN EN ISO/IEC 27001, 27002, 27019, and the IT security catalogue as per section 22 para. 1b of the German statutory requirements (EnWG)integrated.

G 1000

The Technical Safety Management of VNG Gasspeicher GmbH was successfully audited by the DVGW in accordance with the requirements of DVGW Code of Practice G 1000. In this worksheet, the requirements for companies for the operation of gas supply plants are presented with regard to the structural and procedural organization.



The balancing of professional, personal, and family life is an important aspect of our company policy. Since 2013, VGS has been recognised with the "beruf+familie" (job+family) seal of quality, confirming that we properly implement policies promoting healthy family and personal lives for our employees.


Corporate Carbon Footprint

We are currently preparing for certification as a climate-neutral company. The Corporate Carbon Footprint examines greenhouse gas emissions. Using this information, we will develop a climate strategy by analysing which emissions can be reduced or avoided altogether and identifying those for which must we must compensate.
