One of our Greenfish consultants is currently on a mission for a Belgian consulting firm specializing in wood gas generation. He does not work on wood gas generation as such, but on related projects such as trigeneration. Trigeneration is a process that allows the heat produced by a cogeneration plant to be used to generate chilled water (used for air conditioning or refrigeration). The trigeneration process allows for a large reduction in greenhouse gas emissions and significantly improves a site’s energy efficiency.
Wood gas generation waste present on the site is the heat source that will be used for this process. Firstly, the finest fraction of the wood, the part that cannot be gasified, will be used. It’s like sawdust. In addition, the coal remaining after the gasification of the wood, the biochar, will also be used to generate more energy.
Our consultant works both as a Project Manager and as an Engineer on this mission: he defines the tasks and the schedule of the project, writes specifications for the equipment, finds suppliers, manages the budget, and reports on the overall progress of the project.
The beneficiary client of this project is a hospital located 100 meters from the design office. With the help of a boiler, the idea is to burn sawdust and biochar on the site in order to reclaim the heat from the boiler, and to sell part of it directly to the hospital. The other part of the heat will be used to provide the energy needed for an absorption cooling system. Using the heat, this absorption chiller will create water at 7 ° C, which will then be used for the hospital’s air conditioning system in summer.
