DESTRESS is aimed at creating EGS (Enhanced geothermal systems) reservoirs with sufficient permeability, fracture orientation and spacing for economic use of underground heat. The concepts are based on experience in previous projects, on scientific progress and developments in other fields, mainly the oil & gas sector. Recently developed stimulation methods will be adapted to geothermal needs, applied to new geothermal sites and prepared for the market uptake. Understanding of risks in each area (whether technological, in business processes, for particular business cases, or otherwise), risk ownership, and possible risk mitigation will be the scope of specific work packages. The DESTRESS concept takes into account the common and specific issues of different sites, representative for large parts of Europe, and will provide a generally applicable workflow for productivity enhancement measures. The main focus will be on stimulation treatments with minimized environmental hazard (soft stimulation), to enhance the reservoir in several geological settings covering granites, sandstones, and other rock types. The business cases will be shown with cost and benefit estimations based on the proven changes of the system performance, and the environmental footprint of treatments and operation of the site will be controlled. In particular, the public debate related to fracking will be addressed by applying specific concepts for the mitigation of damaging seismic effects while constructing a productive reservoir and operating a long-term sustainable system. Industrial participation is particularly pronounced in DESTRESS, including large energy suppliers as well as SMEs in the process of developing their sites. The composition of the consortium involving major knowledge institutes as well as key industry will guarantee the increase in technology performance of EGS as well as an accelerated time to market.

Europe is confronted with significant changes arising from globalisation and the currently political challenges. This means for example based on the latest developments in Ukraine and exceptionally strong European dependency on gas from Russia, deep geothermal energy particularly based on engineered geothermal systems is becoming even more important to care for Europe`s energy security. If deep geothermal energy from EGSs becomes a significant cornerstone in future energy strategy, there is an urgent need to provide cost-efficient and novel drilling technologies and concepts in order to open up new European geothermal reservoirs for energy exploitation. Therefore the overall goal of ThermoDrill is the development of an innovative drilling system based on the combination of conventional rotary drilling with water jetting that will allow at least 50% faster drilling in hard rock, a cost reduction of more than 30% for the subsurface construction and a minimized risk of induced seismic activity. In order to achieve these goals ThermoDrill will mainly address the following research and development topics: enhanced water jet drilling technology for borehole construction and replacement of fracking; HT/HP crystalline rock jetting and drilling fluids; systematic redesign of the overall drilling process, particularly the casing design and cementing; evaluation of drilling technologies and concepts in terms of HSE (health, safety and environmental) compliance. A challenging project such as ThermoDrill can only be addressed by joint and concerted actions of outstanding experts. This means that the ThermoDrill consortium partners belong to Europe`s leading experts in the field of deep drilling technologies/designs, drilling fluids, simulation, optimal shaping of tools like rockbits, etc. The consortium is already well connected through a variety of long standing research partnerships and wont need great efforts to adjust and synchronize quickly.
