The closed DGH-greenhouse is a high-tech facility, optionally combined with a water farm or sweet water production unit. Special plastic foils are used to filter sunlight, favouring growing light frequencies and blocking heat-generating (IR-) radiation. A specific hot and cold air-distribution system, developed by DGHs own engineering department, combined with special absorption coolers and air conditioners, provide full climate control. Gas turbines or power engines generate power.
A typical Desert Greenhouse Project will cover 20 hectares (50 acres). At first, during the development phase, a feasibility study is carried out. This includes identification of most profitable crops, selection of business partners in the overall value chain, financial aspects, permits, specific local technical requirements and project planning. In many cases, Desert Greenhouse BV can arrange substantial external co-financing. A typical Desert Greenhouse agri-company generates an annual Return on Investment (ROI) of 25 % (minimum: 20 %).
