High-grade electricity is required for essential home appliances, the operation of vehicles, machines, industrial processes, and other applications. Generating and transmitting electricity can result in energy loss, including thermal loss. Fossil fuels will be required to meet energy needs, and this can lead to harmful emissions of C02—a byproduct with its own potential value if properly handled. An affordable localized cogeneration option is needed which eliminates waste and captures useful output. Options are emerging, but are not yet scalable enough to become viable. A market of polygeneration solutions needs to develop which meets the following criteria: 1. Compatible with the direct municipal delivery of properly procured natural gas. 2. Generation capacity of up to 30 people at 500 watts of daily electricity per person. 3. Designed to be located near the structure(s) served in a closet-sized enclosure which is protected from the elements. 4. Makes efficient use of byproducts including waste heat and CO2. 5. Ability to adapt to clean renewable energy sources as they become economically and technologically viable. 6. Scalable as needed to reduce the costs of acquisition, maintenance, and repair. 7. Affordable, with a cost of less than $50,000 per unit.
PowerPoint (Jackson 2011) presents the assumptions used to size a district level genset for NewVistas and includes potential gensets along with the current baseline unit. The model initially called for a district level generator. Recent developments in microturbine technology now make it possible for each NewVistas to have a polygenerator.
Video (Technigeek) demonstrating a micro turbine in development which promises to be extremely quiet and environmently friendly, while costing only a few thousand dollars. If proven effective, this could potentially power a NewVistas standard building based on anticipated consumption.
Wikipedia article discusses the benefits, applications, operations, and maintenance of cogeneration systems. It also discusses the amount of CO2, NOx and SOx that is emitted from the use of some particular machines.
Website argues that smart microgrids are the most rapid and efficient way to achieve reliable, clean electricity service.
