FUTURE ENERGY: Mobile GeoThermal Plant

Aanleiding

All new geothermal well projects need to go through a lengthy development and test phase with a number of challenges and risks.

Dit project aims to demonstrate veel noodzakelijke oplossingen voor de problemen in deze kritieke fase. Een oplossing wordt gezocht voor een verminderde dead time, meer hernieuwbare energie, minder CO2-uitstoot (en gebruik van aardgas), bij voorkeur via een gestroomlijnd proces.

Vijf aspecten zijn belangrijk:

1. Enable quicker permit applications;
2. Enable development of more projects;
3. Produce renewable energy sooner;
4. Design and build a more efficient permanent installation;
5. Process the hazardous testing water swiftly and environmentally friendly.

Dit project heeft als doel een oplossing te bieden voor deze problemen, mogelijk gemaakt door een aantal eerdere activiteiten van GtS, door het ontwikkelen van een mobiele installatie.

Doelstelling

Gastreatment Systems (GtS) proposes a solution, the Mobile GeoThermal Plant (MGTP), which is a completely functional containerized geothermal unit for temporary use in the development and test phase.

It produces energy from heat and arising natural gas, and it is set up with a comprehensive measuring unit to ensure a more efficient final installation design and technology from the process industry that turns polluted waste test water into a manageable brine.

The aim of the project is to build a demo MGTP installation. With this first physically built installation, issues like construction details, control strategies, and safety aspects will be optimized in order to bring reliability and accuracy to a high level, ensuring optimized operations in producing renewable energy and treating test water.

Korte omschrijving

This project is dedicated specifically to the construction of the demo MGTP installation. GtS, being the sole applicant of this grant, will execute all activities.

GtS will remain the sole owner of the MGTP for its whole lifetime and reap the energy-related benefits (i.e. renewable heat production). All non-construction related activities (drilling, civil work, etc.) fall beyond the scope of this project.

The project will be executed through 6 work packages (WP):

• WP 1 Purchasing
• WP 2 HSE Case
• WP 3 Mobile test unit (3 containers)
• WP 4 Water treatment unit (3 containers)
• WP 5 Power unit (3 containers)
• WP 6 Location preparation, on-site connection and commissioning

In WP 1 worden alle noodzakelijke apparatuur en materialen voor de 9 containers die de MGTP vormen, aangeschaft. In Work Packages 2-5 worden de respectieve containers geconstrueerd. Na de voorbereiding van de locatie worden ze ter plaatse geplaatst, aangesloten en in gebruik genomen (WP 6).

Resultaat

The MGTP will enable:

• 21.600 thazardous water from the test phase treated;
• 47.000 MWh additional renewable heat generated (which would otherwise not be utilized);
• Capacity can increase to up to 24 MW, depending on temperature of the well and availability of geogas;
• 4.7 x 10^6 Nm3 natural gas savings;
• Operational costs € 1.098.118 for a 6 month test period;
• Gross profit of € 401.882 for a 6 month test period;
• Additional income from renewable heat up to € 1.011.917 for a 6 month test period.

The numbers above are based on each application of the MGTP. These cover a period of 6 months (including maintenance). GtS expects to place the MGTP during the test phase of at least 10 geothermal installations in the Netherlands in the next 5 years.
