What is DH?

District heating (DH) is a system for distributing heat for both residential and commercial heating requirements (space heating, hot water).  The fundamental idea is to either recycle surplus heat from other processes which would be wasted otherwise or to have centralized/decentralised heat generation units which can meet a certain heat demand. DH systems produce medium – steam, hot water or chilled water which are then distributed to end-users. As a result, end-users do not need heat generation units such as boilers or furnaces. Numerous benefits can be achieved by connecting both residential and commercial sectors to DH network such as improved energy efficiency, fuel flexibility, enhanced environmental protection, decreased costs and reliability.

Different generations of DH systems

Over the last decades, DH systems have been developed by introducing new technologies and by increasing energy efficiency. These changes have had a wide range of consequences which resulted in four different generations of DH systems in terms of technology, heat distribution, medium, circulation systems etc. Starting from the 1st generation where the heat carrier was steam, the last, 4th generation of DH provides low temperature DH systems with water at 30-60°C, depending on requirements. Apart from the heat carrier, circulation systems have changed from steam pressure and central pumps only to more sophisticated central and decentralised pumps. Another important development can be found in substations and radiators (heat exchangers) where floor heating and low-temperature radiators will be used.

Technologies used in DH systems

There are various heat sources which can be used for generating heat in DH systems including combined heat and power (CHP) plants, heating plants which can use biomass or fossil fuels, geothermal heat, solar heat, heat pumps and heat-only boilers. It should be mentioned that these sources can be combined for more efficient DH systems such as combining CHP units with heat-only boilers or heat pumps. Another component of DH systems is, mainly thermal, energy storage, which is used for storing excess energy. For the STORM project, geothermal systems and heat-only boilers are deployed. When it comes to geothermal DH systems, heat is extracted from the ground by creating drilling wells which is then used for meeding space heating demand or hot water preparation. In a system like this, no fuel is required since extracted heat is applied for medium preparation. On the other hand, heat-only boilers need fuel for generating heat. However, with the development of this technology, high energy efficiency can be achieved in a sustainable way by using bioenergy.

Control, automation and monitoring in DH systems

An important segment of DH systems operation are control, automation and montoring withing the system for the most efficient working load. DH controlers and system can provide trouble-free and energy-efficient network operation. Control valves, actuators and sensors in combination with proper communication within the system can ensull that all requirements are met in the most efficient, cost-effective way as fast as possible. Moreover, with the development of technology, it is possible nowadays, with the sophisticated systems and forecasting, to predict heat demand to be met by DH system. By doing this, peaks and requirements can be predicted and modelled accordingly which results with great flexiblity, automation and control.

About us


a. What is the relationship between the Yield Lab and Cultivation Capital?


Cultivation Capital is a large St. Louis Venture Capital firm investing in information technology, life sciences and financial technology. The Yield Lab is an independent venture capital fund contracting Cultivation Capital for back office support, such as: deal flow, due diligence, finance/accounting, legal and program management and event set up. 

Cultivation Capital is closely aligned with Yield Lab operations, which provide a great source of quality deal flow and a front row seat to the development of Yield Lab portfolio companies. Companies in the Yield Lab portfolio have the opportunity to speak with the Principals and Partners of the larger Cultivation Capital investment funds. Some companies have syndicated with the Yield Lab or been a lead investor in future rounds of Yield Lab Portfolio Companies. 

b. What is the relationship between the Yield Lab St. Louis, the Yield Lab Europe and The Yield Lab LATAM?



All YL accelerators operate distinct, independent venture capital funds, each with its own management team but under the guidelines of The Yield Lab Institute. All of the Yield Lab funds operate under the same guiding mission & principles.

b. Why was the Yield Lab created?



We believe that innovation and investment in agriculture technology will play a vital role in securing a more food secure future and reaching the necessity to feed a population expected to reach over 9 billion by the year 2050. 





The Yield Lab Accelerators


a. What sectors does the Yield Lab invest in?


We’re interested in technologies that will revolutionize the agriculture and food systems to sustainably feed the world. In order to most effectively transform these systems, it is essential that we consider all parts of the food and ag systems. The Yield Lab invests across technologies in the following focus sectors: crop production, animal health & welfare, precision agriculture, waste reduction, logistics, urban agriculture, and food ingredients.



b. What qualities do we look for in a company?


The Yield Lab invests in companies that are revolutionizing the agriculture and food systems to sustainably feed the world. 

We invest in companies with a management team and a minimum viable product.

Most importantly, we look to be a value-add investor, and as such, we inspect each company for fit within our resource network.

Companies must be:

  • Revolutionizing ag and food to more sustainably feed the world
  • Business to Business product or technology
  • A legal entity
  • Scalable
  • Commercial ready


c. What geographies do you invest in?



We are geography agnostic – we’ll invest in any company, from anywhere. That said, we do consider geography in our investment choices – we’re a value-add investor, and it can be difficult for us to add value in certain geographies.



d. What stage companies do you invest in?


We like to describe ourselves as a “later stage accelerator.” We’re equally comfortable working with early stage to guide them as they raise seed financing as we are working with later stage companies to partner with strategics and to scale.



e. Do you take equity?


Yes, we take equity in exchange for investments. We also expect to receive warrant coverage for programming and mentorship. The terms of each equity investment are negotiated on a case-by-case basis because we believe that is the best way to serve our entrepreneurs.



f. Is there anything the Yield Lab won’t invest in?


We don’t invest in production facilities (farms) or businesses that rely solely upon direct-to-consumer sales.



g. What does the Yield Lab St. Louis offer?


  • $100,000 in equity investment
  • Access to our award-winning accelerator programming, which focuses on customers, collaborators, and capital
  • Individualized mentorship from our team
  • Access to The Yield Lab global network, including strategic corporate partners, producers, investors, entrepreneurs, and more



h. What does the Yield Lab Europe offer?


  • $100,000 in equity investment
  •  Access to the premiere agtech accelerator program in Ireland
  • Individualized mentorship from our team
  • Access to The Yield Lab global network, including strategic corporate partners, producers, investors, entrepreneurs, and more



i. What does the Yield Lab LATAM offer?


  • $100,000 in equity investment
  •  Access to the premiere agtech accelerator program in Buenos Aires, Rosario, Sao Paulo and Saint Louis
  • Individualized mentorship from our team
  • Access to The Yield Lab global network, including strategic corporate partners, producers, investors, entrepreneurs, and more



j. Can I re-apply?


Absolutely. We intentionally keep our application concise and accessible so that entrepreneurs can apply easily and can update their application frequently. Frequently, the decision to pass on investment is due to timing, either on our end or yours. That said, we recognize that things change quickly, especially in the start-up world, and we love to see companies progress.
