Mobile Heat Exchange Container - Mohec

SDF container
  • Sustainable Heat Source

    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.

  • Save Money

    The grower reduces its energy costs because the Mohec its heat is ODE free.

  • Get a better price for your electricity

    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.

  • Optimize your CHP usage

    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.

Interested?
We gladly come by to personally meet but we are also open to firstly communicate over the phone or any other desired means of communication. During our first acquittance we’d like to take the time to go over our team, our solution and the potential possibilities. We dive deeper into the Mohec and show you how the Mohec can be used to optimize the energy consumption and production in each specific situation. After we did a generic analysis in which; the specific situation of the grower, the grower its vision and needs, its demands and capabilities are taken into consideration and we move to the next step and conduct an energy analysis.
Our Mohec will become a crucial component of the energy and cv-infrastructure of the grower. Therefore, it is of the utmost importance that SDF has a clear understanding of the boiler infrastructure, the CHP, the cultivation strategy and the heat requirements of the greenhouse. We will create a model based on all the collected data. Our energy specialist will analyse the data and dimension the Mohec based on the thermal energy requirements of the grower. This model will visualize how the Mohec will enhance and enforce the CHP, substitute fossil fuels from the boiler with a mix of sustainable heat and what kind of profit the grower will make. This phase will end with a proposal in which the technical and financial details are described.
A formalized collaboration between SDF and the participants is crucial for the long-term success of the project. SDF shares the profits of the Mohec with its participants within either a BV or a VOF construction. The earning capabilities of each individual participant forms the foundation of the collaboration. Transparency is essential to embed trust in our partners. During this phase we need to answer the following questions: 1. Which participant will be involved in the collaboration? And the supplier of the CHP? Additional external financers? 2. How will the revenues be shared; what kind of expenses are covered by the collaboration? 3. What kind of shape will the collaboration take? A partnership contract, a supplier contract, a VOF or a BV?
SDF firmly believes in collaboration. Therefore SDF proposes to start a new entity in which both companies take part. The shares will be divided based on investments, participation and risk. The earning potential of both parties should be satisfactory and reflect the risk both companies take.
We will analyse the available means of financing based on the principal that each participant carries its equal financial responsibility within the collaboration. External financing will in most cases be required. What are our possibilities?
We can start placing orders once the other phases have come to a successful completion. We will prepare and arrange the installation procedures. This process can take up to a couple of months depending on external parties like Liander or the municipality.

How do we do it?

Residual heat as the solution

  • Immersion cooling

    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.

  • Infrastructure

    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.

  • Monitoring & Control

    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.

3d models
Plug & Play

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.

Modular design

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.

Plug & Play
  1. Cool fluid is brought underneath the servers.
  2. The pressure forces the fluid up into the server.
  3. The server dissipates its heat into the fluid
  4. The fluid reached the top and flows over the side of the unit
  5. The warm fluid is directed into the heat echanger
  6. The heat exchanger is connected to the return pipe and cooles the fluid down to 40 C while it heats up the return pipe to 55 C.
  7. The process starts again

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!

Datacenters are powerhungry and consume a lot of electricity. Traditionally, this is a waste product that is destroyed. Our sole mision is to change this mindset and develop datacenters that reduce our carbon footprint instead of raising it.
