Geothermal Exploration introduces the subject of geothermal energy and its development around the world. The text defines a series of ‘geothermal play types’ based on geological setting and then presents strategies and methodologies appropriate for each play type to move a geothermal exploration program to the stage of committing to exploration drilling. These methodologies include permitting, environmental, geology, geochemistry, geophysics and remote sensing techniques used throughout the world for specific play types. The book covers a large number of geoscientific techniques and focuses on their applications to both convective and conductive geothermal systems, with extensive reference to the international literature.

‘Ladsi Rybach is one of the best known and respected proponents of geothermal energy in the world today. He has worked tirelessly on behalf of the geothermal in Europe and through his efforts at the International Energy Agency and the International Geothermal Association his influence has been felt everywhere’

IEA-GIA Executive Committee, Bali, Indonesia, April 2010

Have you ever met someone and instantly felt that you are in the presence of someone bigger and wiser than you? Well, this is how I felt, when I first met Ladsi. Working at the IGA I’ve heard his name many times, of course. But hearing and ‘experiencing’ are two different things.

Being a true professional and simply a wonderful human being, Ladsi emits sparks of wisdom and tranquillity. Graceful and intelligent and a gentleman as he is, he always acts with poise when interacting with people. And how could it be different, if he is full of passion for what he does. Ladsi is one of the key people standing at the source of the geothermal energy and the IGA. A founding member of the International Geothermal Association, he has served the IGA Board for more than 18 years (which is more than the half of the IGA existence!) having a position of both President and Vice-President and still being active as a Committee member.
Founding members of the IGA, Castelnuovo/Italy, May 1989

His passion for geothermal is hard to overestimate. Trained as a geophysicist, he was a professor at the Swiss Federal Institute of Technology (ETH), Zurich and led the research group ‘Geothermics and Radiometry’ for more than 20 years. He has also founded a successful consulting group GEOWATT, which is still present on the market ( His achievements list is far too long, but some of his most memorable traces include more than 500 publications, about 100 geothermal conferences attended and special contribution to the high-level reports and papers including IPCC Special Report to mitigate Climate Change (2008), and of course his world-class geothermally-famous concert during WGC 2005.

Oh yes, have I mentioned that he is a professional conductor? For several decades Ladsi was the Musical Director of Orchesterverein Zurich. The special concert during WGC 2005 in Antalya, Turkey was one of his numerous concerts he has conducted in and out of Europe. The musical pieces of W. A. Mozart, J. Brahms and R. Wagner and of Turkish composers became alive under his baton.

Though having a thorny life, especially at the young age, changing countries, being a refugee, this brilliant person embraced it all and what’s more important saved his witty and special sense of humour. ‘Oh listen, I have a funny joke to tell! I remember once…’, – this is what you normally will hear from him. And be prepared to enjoy an amusing story somehow related to the Geothermal Community.

Ladsi’s entry to geothermal started initially in the early 1970s from his engagement in uranium exploration. He got acquainted with the radioactive heat generation of rocks. From there he came to work with heat flow (was active in the International Heat Flow Commission 1975-1987 and 1995-2003) and understood the relevance of this energy source. Now, he is sure that geothermal energy should play a role that corresponds to its great resource potential and when talking about his passion for geothermal, he always says: ‘But it’s down there, everywhere! Just use it for God’s sake!’.

His main interests in geothermal lie in the sphere of ground source heat pumps, sustainability and EGS. Right now, Ladsi is 84 years old, retired (but not tired!) and lives in Switzerland with his wife Ruth and son Manuel (a banker).

What did I want to say with this IGA Special? I believe, it is important to find the time to acknowledge and thank people we meet now and then. Last year, I’ve met an outstanding advocate of geothermal and I would like to thank him on behalf of the IGA and the Global Geothermal Community for bringing geothermal to the forefront of the international stage and reminding us that we still have a long way to go. Thank you, Ladsi.

May the geothermal warmth will heat your heart and home for many years to come.

We want you!

The IGA and its partners World Bank and IRENA with its Global Geothermal Alliance as key partners jointly organised an UNFC Geothermal Specifications workshop in Addis Ababa, Ethiopia between 5 and 7 February 2019. The workshop forms part of the UNFC pilot project in which the IGA and partners seek to deploy the UNFC geothermal project classification across the globe. For this we have worked intensively with the United Nations Economic Commission for Europe, for whose support we are very grateful. In Ethiopia we were hosted by the Government of Ethiopia and the Ethiopian Geological Survey. A word of thanks goes to Geothermal Director Dr Solomon Kebede without whom this Workshop would not have taken place. We also express our gratitude to Dr Meseret Teklemariam representing the UNEP and the African Geothermal Centre of Excellence. She is our geothermal ambassador for the region and helped the team setting clear targets and expected outcomes.

The workshop was lead by Prof. Dr. Gioia Falcone, Mr Greg Usher, Mr Rob Hogarth and Mr Harmen Mijnlieff who dedicated their time, energy and passion for Geothermal in Addis Ababa.

We had the pleasure working with 23 participants coming from Ethiopian Geological Survey, Ethiopian Electric Power, Cluff Development Project, and local developers. We have seen 22 potential projects out there waiting to be classified and come to full bankability. In the mean time, the groups have focused on the Aluto project and the first classification results are expected later this month.

After returning we received the fantastic news that KenGen and Shandung Kerui Oilfield Service Group have secured a §76.8 million drilling contract for the 70MW Aluto-Langano project in Ethiopia. Ethiopia has the potential to become a geothermal giant and we are convinced that giant will be awake very soon.

On February 18 and 19 the IGA Team visited the United Downs Deep Geothermal Project in Red Ruth, Cornwall, UK. The UDDG project is led by Geothermal Energy Limited (GEL). The drilling contractor is a venture of Angers and Sohne and Marriot Drilling. The onsite operation team is led by Peter Ledingham (Managing Director), Lucy Cotton (Chief Geologist), Susy Doe (Communications Officer) and Jon Gutmanis (Operations Geologist).

The visit was organised by Prof. Iain Stewart, University of Plymouth, who kindly hosted the IGA Team first in Plymouth and then took us on site on Tuesday Feb 19th. The UDDG project aims to drill two deep wells into the heat-producing granites located at a permeable geological structure called the Porthtowan Fault Zone. One well will be producing the heat, the other well will be reinjecting the cooler water into the ground in order to be reheated. Expected bottom hole temperatures are to 190 oC and the targeted depth is 4,500m.

A few words about the funding…

GEL has secured funding of £10.6 million from the European Regional Development Fund to explore the geothermal resources underneath Cornwall. Cornwall Council contributed (£2.4 million) and private investors lend £5 million. The total sum secured the drilling of two deep wells to build a 1-3 MW pilot power plant to demonstrate the technical and commercial viability of supplying both electricity and heat.

Visual communication and social acceptance was not forgotten as well…

And then there was Ms Molecule. Ms Molecule – a great invention of the communication team to raise awareness of how the hot water turns to power and is used by communities to power up their homes and mobile phones has been proving worthwhile. School classes, local people, county representatives, they all love Ms Molecule and seem to engage more strongly to the project than ever imagined.

Our personal observation…

It is a team effort to get challenging projects like these going, and it takes strong individuals such as Peter Ledingham and his entire team to continuously strive to make these projects happen on the ground. Granite green energy: we all talk about it, and Cornwall is doing it! Thank you for having us, it was simply fantastic.

What else can we say, we simply #lovegranite

The Baltic Symposium featured 12 country presentations and a high level overview on the global geothermal state of play presented by the President of the International Geothermal Association – Alexander Richter. In particular, the GeoTherm conference taking place on 14-15 February highlighted the increased awareness of geothermal energy in Germany and Central Europe.

The IGA was present with a booth showcasing our new Insider Club and the initiatives we are setting up with our partners on technical standards such as well designs and the UNFC geothermal specifications that we have deployed in three countries, Indonesia, St Lucia and the Caribbean.

Over 1200 people attended the conference which featured 15 presentations and 200 exhibitors.

On the 7th and 8th of March 2019, the partners of the GSS-VET project came together for the 5th project meeting at the Technical University in the amazing city of Sofia, Bulgaria. The IGA has been represented by Gregor Rumberg.

The 15 project partner organizations from Bulgaria, Germany, Greece and Spain are well prepared for the final phases of this exciting project, which include international pilot workshops and the “training of the trainers”. An interactive learning platform is almost ready to launch soon and will be a helpful tool to support the education online.

The GSS-VET project combines and promotes Geothermal and Solar Skills in Vocational Education and Training. The training content is focused on technical skills, but also on transversal ones, including entrepreneurship, ICT, interdisciplinary skills and ability to work effectively with people from other disciplines.

40 trainers and 200 workers will directly be trained during the project’s lifetime, and thanks to the involvement of VET providers, sectorial organizations (including an EU umbrella), regional authorities and other associated partners, 2,500 workers will be trained by 2025.

Are you interested in a big opportunity and becoming a trainer or trainee? Please contact for more information.
