Meiny Prins opened the seminar with an inspiring speech about the Sustainable Urban Delta and the role for the international horticulture in the global food challenges. New energy sources is an important subject in the sustainable urban delta. Prins put the subject of the seminar in a wider perspective.
Sustainable energy is the future
Senior researcher on the subjects’ climate and energy, Feije de Zwart (Wageningen UR), finds specifically horticulture suitable for use of alternative energy, because of need of heat and CO2. The necessity of alternative energy is nearby, because fossil fuels will end and heat of the sun is for free. Also sustainability is important. More and more rest heat will be used in near future.
Afterwards vegetable grower Kees Vahl shared his experiences in the geothermal project in the Koekoekspolder (The Netherlands) and his recently build nursery in Bralitz, East-Germany, which uses the warmth of the nearby situated carpentry. His biggest challenge in both projects was and is retired partners and finance. Vahl and his brothers had enough persistence to continue. They strongly believe in the technics and the awareness that use of fossil fuels will end. Another important motive is the large demand of local products in East-Germany. “First find a market, than realise a project” is his advice.
Warmth and cold of the globe
Director of Installect, Gerrit Kamphuis, learned the visitor about possibilities of storage of heat and cold and drill methods. Dick van Giezen (Carrier) speeched about the innovative technology of heatpumps in which heat is being replaced. This month a new heatpump will be launched which can reach up to 80°C.
Remi Blokker, director of Bluerise, shared his knowledge about induction of electricity through temperature differences of sea water and the technics of cooling with sea water.
The start of the final panel discussion was an introduction of Gyula Mózer, the expert in geothermal energy and Hungarian director of Global Greenhouse Kft, greenhouse constructor. A Hungarian geothermal project is less expensive than in the West-European countries, due to regulations and the availability of geothermal energy in Hungary.
In the panel discussion, the visitors used the opportunity to learn more of the speakers. The interaction in this panel discussion was a valuable end of the seminar.
During the network lunch the discussion and sharing of knowledge continued.
Priva is proud on this successful event, in which 60 visitors of many different countries participated.
