Mobile Heat Exchange Container - Mohec
SDF its solution enables growers to meet the sustainability guidelines up to 2040 by replacing their boiler gas by CO2 free residual heat from our immersion cooled servers.
The grower reduces its energy costs because the Mohec its heat is ODE free.
The grower receives a better price per MWh from its CHP by utilizing the energy surplus through the Mohec versus selling it on the grid.
Our Mohec is dimensioned based on the left-over capacity of the CHP. This allows the grower to more easily run its CHP and plan according to its energy needs. The grower doesn't have to bother thinking about market prices and can focus itself on its cultivation.
How do we do it?
SDF uses an innovative technique called ‘immersion cooling’ In order to maximize the utilization of the residual heat dissipated by the servers. We submerse the servers into a ‘bath’ of di-electric fluid. This fluid is specifically designed to capture the heat as efficient as possible without conducting electricity. This cooling method enables us to cool our servers very efficiently and therefore optimize the exploitation of the server. In addition, the fans are removed and therefore the whole installation makes practically no noise.
Our infrastructure has been designed to use the return pipe as a means to cool the servers and on the other hand to deliver the dissipated heat to the greenhouse. We do not require any additional implementations to deliver the heat. SDF provides its heat in between 50 to 60 C, depending on the heat requirements of the greenhouse and the possibility to further heat the warmth up. Our system can be compared to an electrical boiler. We deliver 95% sustainable thermal energy of each KWh consumed by the servers.
SDF implements a real-time remote control system. In addition, the system also provides insights in regards to heat production, electricity usage and it provides financial insights with regards to the operation.
The Mohec is a plug-and-play system that requires minimal adaptations in the existing infrastructure. The different components of the Mohec are pre-installed in the workshop and assembled. This allows SDF to place the Mohec in a relatively short time.
SDF aims to use the space in the container as optimal as possible. The Mohecs have a dimension of 12x2x2 and can produce up to 1MWh thermal heat. The cooling containers that contain the servers are stacked on top of each other to maximize the usage of available space. This allows SDF to place 8 cooling containers in one Mohec. One cooling container can cool up top 30 servers which makes the total capacity of the Mohec 240 servers.
Bridging the future
The Dutch horticulture is known around the world for its keen eye for innovation and willingness to adopt new technologies. Unfortunately, geothermal energy is not the answer to the problem for everyone and the current ODE is hindering many businesses to take the next step towards sustainability. Sustainable minded greenhouses are currently (re-in)installing CHP’s due to the economic burden that sustainability carries. We believe that a change is coming but it will take some time. That time can be bridged by a Mohec.
The Mohec can act as an additional heatsource till there is clarity on how the government intends to proceed. Hence, the government decides to move the ODE to gas, we can just make the datacenter larger to substitute your CHP in the future and make your greenhouse 100% gasfree!
