SwissDGS – EAPOSYS Business Model in Action
Throughout the week, SwissDGS welcomed visitors to its booth, featuring the joint venture between Amberg Group, Basler & Hofmann, and EAPOSYS.
On the Swiss Day (Wednesday), Naomi Vouillamoz presented the SwissDGS technology and business model — the first operational implementation of the EAPOSYS PMC model, enabled by the Migros Pioneer Fund.
Her presentation highlighted how closed-loop deep geothermal systems can deliver long-term, fair, and reliable heat solutions in Switzerland — without fracking and with minimal environmental impact.
Scientific Contributions
SwissDGS and EAPOSYS also contributed two scientific posters, reflecting their shared commitment to technical excellence, sustainable financing, and social responsibility in the development of AGS:
Site Visit to the Hagerbach Test Gallery — A Glimpse into the Future
The week concluded with a site visit to the Hagerbach Test Gallery, an underground research and testing facility of national importance, where Amberg Group (SwissDGS co-founder) is majority shareholder. There, SwissDGS and EAPOSYS showcased the AGS technology and the SwissDGS roadmap to delegates and partners, including Sam Abraham from Halliburton, whose participation highlighted how oil & gas expertise can accelerate the industrialization of advanced geothermal systems.
This day marked the announcement of a third-party press release by Halliburton – EAPOSYS highlighting our intent to collaborate long-term toward the industrialization of AGS – the result of almost two years of alignment and joint exploration between our teams.
