2nd CGS Europe Knowledge Sharing Workshop - Natural Analogues

17 - 19 October 2011 - Maria Laach, Germany
Studying natural analogue sites is a unique opportunity to improve the understanding of physical, chemical, biological and microbial processes that may occur in a CO2 storage reservoir and the surrounding geological domain in the long term. Furthermore, potential impacts in case of leakage can be investigated and monitoring techniques may be tested.
Who should attend?
As sharing of experiences and good practices will help researchers to maximize their time and resources in similar contexts, CGS Europe organizes a specific workshop on natural analogues, essentially aimed at scientists. The workshop will of course present results from international research projects, but moreover, debates will form an essential part of the workshop since its overall aim is to hatch new ideas for research and cooperation projects, e.g. focussing on regions which are not well-known so far.
The workshop will be held on October 17-19, 2011 at the “Seehotel” in Maria Laach, Germany, alongside the infamous Laacher See (
Workshop schedule
Su, 16th Oct.: First day of arrival.
Mo, 17th Oct.: Registration starting at 8.30 h, workshop from 9.30 h onwards.
Tu, 18th Oct.: Field excursion (lunch packs will be provided).
We, 19th Oct.: Workshop from 9.00 h onwards.
CO2GeoNet General Meeting in parallel.
Th, 20th Oct.: CGS Europe General Assembly from 9.00 h onwards.
Five major sessions are planned for the Natural Analogue workshop. They cover the following aspects:
  • Storage complex processes (e.g. CO2 migration, geochemical alteration, geomechanics)
  • Leakage processes (e.g. brine, CO2, faults, spill points, CO2 springs)
  • Impacts (e.g. on vegetation, groundwater, adapted ecosystems, accidents)
  • Monitoring of storage complexes (testing of methods and concepts at natural sites)
  • Others (may include industrial analogues)

Since the number of rooms available at the “Seehotel” itself is limited we may need to accommodate some participants in other hotels in the nearby town called Mendig.
We will organize accommodation along with the registration which is open now.
On a “first come–first served”-basis, early registrations will be for “Seehotel”, while later registrations have to include the other hotels as well.
A night at “Seehotel” is at € 85.00 (incl. breakfast), the other hotels are not more expensive.
If necessary, a taxi shuttle service from these hotels to the workshop venue will be arranged (once in the morning, once in the evening).
Registration is closed; the deadline was the 8th September 2011.

Getting there
By plane: Maria Laach and Mendig are located between Frankfurt (150 km) and Cologne (65 km). These cities have numerous international flight connections. Many budget airlines fly to Cologne/Bonn airport, (e.g. Easy Jet, German Wings, HLX). Ryan Air flies to Frankfurt-Hahn, which is approximately 100 km away.
By car: Maria Laach and Mendig are easily accessible by car, motorway A61, Exit Mendig/Maria Laach.
By train: Trains from Frankfurt airport to Andernach are frequent and take about 1.5 to 2 hours (via Koblenz, or Mainz). Trains from Cologne/Bonn airport (most via Cologne Central Station) are frequent as well and take about 70 to 90 minutes. Prices for the train tickets (one way) are in the range of 20 to 25 € from Cologne/Bonn Airport and Frankfurt Airport (here avoiding the much more expensive ICE train), respectively.
Tickets are available at ticket machines and at DB counters.
Train connections can be found at
From Andernach railway station taxis are recommended to Maria Laach (approx. 15 minutes at about 25 €/taxi).
For Mendig, a local train from Andernach could be a less expensive but more complicated option (verify using the above mentioned link).
