Geothermal energy
Geothermal energy is a sustainable source of energy generated by the heat of the Earth’s core. The ground contains natural aquifers and the deeper they are, the warmer the water stored in the earth. This hot water can be pumped up and transferred to heat networks by heat exchangers. From there the water in the heat networks can be distributed to users including greenhouse farms. After use, the cooled water from the aquifers goes back into the earth.
Alewijnse has extensive experience in the automation and electrical installation of all control systems for above-ground geothermal plants and their heat distribution networks. These systems manage the extraction of geothermal heat from the 2,300-meter-deep production well, control the heat exchangers, operate the degassing installation, manage the production and injection filters, operate the transport and injection pumps, distribute energy to end users, and handle the return transport of water to the injection well.
Flexible and user-friendly systems
Alewijnse lead engineer Arjan Broeken explains the technology behind the Alewijnse installations: "The control systems are based on advanced PLC/SCADA solutions with components from the Siemens 1500 series. The installations are flexible and user-friendly, and provides extensive data on, for example, temperatures, pressures, levels and flow rates. Using intuitive displays, real time information and the status of the installation can be easily viewed by all users, such as the management, operators and end customers.
"All important information is continuously stored and this allows us to generate any report automatically,” continues Arjan Broeken. “This information is available at both the geothermal wellhead and via mobile devices such as tablets and smartphones. We report any malfunctions directly to the trouble-shooting service, allowing the client's operations team to intervene quickly to ensure the continuity of the processes. We deliver the same service to our existing geothermal projects. The stability of the energy supply is vital for companies in the greenhouse horticulture sector."
Alewijnse's extensive expertise and many years of experience in the industrial and maritime sectors means that they are at home with all types of automation solutions and electrical installations and have good contacts with the right suppliers. This allows them to take on entire projects as a partner and deliver total packages in the areas of data processing, automation, process controls, hardware, electrical installation and commissioning, thereby creating maximum added value for our partners and end users.
