The key objective of the SCCER-SoE in its Phase II is the initiation and in some case completion of demonstration projects in all areas of the our electricity supply portfolio. The new work package 5 is central to the strategy of implementing the integrated approaches developed for geo-energy (WP1) and hydropower (WP2) and the innovative technologies developed in WP3 in projects conducted with industry, which serve to demonstrate the feasibility of the proposed approaches.
The final objective of the innovation roadmap remains to develop by 2025 a portfolio of tested solutions to enable reaching the Energy Strategy 2050 supply targets.
The deep geothermal underground laboratory (DUG Lab) project aims at a better understanding of hydro-seismo-mechanical coupled processes that are associated with high pressure fluid injections in a crystalline rock mass. Experiments are carried out at laboratory scale (a few centimeters) and at intermediate scale (a few tens of meters). |

In September 2016, the SCCER-SoE invited journalists for a visit to the Grimsel rock laboratory to explore the experiment „In-Situ Stimulation and Circulation (ISC)“ led by Dr. Joseph Doetsch. Learn more about the journalists‘ impressions and the project in the following TV reports and newspaper articles:
GeoEnergie Suisse AG is developing a pilot and demonstration project for deep geothermal energy in the village of Haute-Sorne (Jura). Planned is a petrothermal deep geothermal project reaching down to 4000 – 5000 m. The system is projected to deliver up to 5 MWe and/or heat for industrial processes as well as district heating. The total project costs are roughly 100 Mio CHF. For the first time, the project will implement the so-called multi-fracture system in a granitic environment. Drilling is scheduled to start in 2017 or 2018. |

This demonstration project will be implemented as part of the “GEothermie-2020” program of the Canton of Geneva. A step-wise approach including drilling wells (production and storage) at progressively increasing depths (1500-2500 m) will be performed by SIG during Phase II (Q4 2016 – 2017). This will provide the opportunity to test and validate the effectiveness of exploration concepts and models developed within WP1 as well as proof the feasibility of direct heat production and subsurface storage potential in sedimentary basins at relatively shallow depths. The project is already approved and in advanced stage of realization. |

According to IEA, IPCC and COP21, CCS has to be implemented to keep global warming within 2°C. After a long phase of experimentation on capture and sequestration technologies, efforts in Europe to implement a concrete strategy are growing, under the umbrella of the ECCSEL ESFRI infrastructure and the newly approved ERA-NET Cofund ACT. The Swiss plan is being developed by SCCER-SoE groups together with SFOE, BAFU and industry participation (on-going discussions with three possible industry partners). The plan aims (i) to use the ERANET-ACT support to expand the work already carried out in SCCER-SoE Phase I and previous national projects (CARMA) to ensure that the required science and technologies are available, and (ii) to realize a first pilot project in Switzerland to demonstrate at the field scale that CO2 storage can safely be done without causing unacceptable seismicity, fluid-mineral reactions and environmental contamination. The timescale of ERA-NET Cofund ACT is very favorable, with expectation of funding by 2017 (Swiss quota of 4 MFr for 4 years). We aim at initiating with SFOE a CO2 sequestration pilot by 2019. |

A new small HP plant that will be installed/built in the coming 2 to 3 years will be selected to provide a comprehensive set of research carried out by SCCER SoE partners (and if possible SCCER Furies and SCCER Crest). Thanks to a concurrent approach, this demontrator will show the ability of a small hydropower station to produce clean, sustainable and renewable energy while producing ancillary services. Using the results from WP2 and WP3, several topics will be addressed such as: the now-casting and seasonal forecasts of discharge to the water intake as a basis for sediment management and for a flexible power production scheme; a critical review of the implemented operation practice, in view of efficiency improvements considering multi-sectorial objectives; a technical optimisation of the hydro electrical equipment operating conditions allowing a flexible control and set up of a predictive maintenance; investigation of the ecosystem functioning (metabolism, food web), fish migration and biodiversity; assessment of the new regulation for small hydropower plant and the possible financial models. |

Following the preliminary implementation carried out in the Mauvoisin reservoir in Valais, we will implement a project with HP industry with the goal of demonstrating the effectiveness of technologies to artificially stir the water stored in a dam reservoir to prevent sediment from settling and allow for the sediment to be conveyed downstream at acceptable rates through the turbines. The mobile mixing devise (demonstrator) will be tested at several dams (1 to 3) to show its efficiency in different conditions. |

FLEXSTOR will test a set of innovative tools for flexible operation of storage hydropower plants in changing environment and market conditions at a complex hydropower scheme. This demostrator is motivated by the main hydropower challenge in Switzerland, namely the need for flexible operation targeting premium remuneration hours, for which comprehensive methodologies for hydropower upgrading projects are still missing. |
