What are nGen Systems?

nGen Systems are made of individual modules that can be integrated on site in a variety of ways to match specific customer demands. These individual modular components of nGen Systems are well proven.  Some are commercially available off-the-shelf while others can be readily manufactured based on well known existing designs and techniques.

The fundamental innovation in our technology is in how those components are specified and integrated into an nGen System in order to supply end user requirements at costs and efficiencies that legacy infrastructures simply cannot match.

It is generally recognised in the co-generation domain that the best diesel engines currently achieve only 45% efficiencya. Gas turbines can achieve higher efficiencies but only at very large sizes (e.g. central power station sizes), well beyond most on-site requirements (and in central power stations most of the waste heat remains unused).

In cogeneration or tri-generation installations based on reciprocating piston engines or gas turbines, the heat and electrical power outputs remain closely linked rendering difficult variations of individual energy streams.

nGen Systems  enable substantial increases in mechanical and overall efficiencies. It also opens the way to use in modular fashion component technologies with low operation and maintenance cost and that have been in use for over 100 years. This same move frees up energy sources where an nGen System can be switched from fuel to fuel with only minor adaptations. This opens the way to being able to choose lower cost fuels as markets evolve.

a See for example, http://en.wikipedia.org/wiki/Diesel_generators indicating that a modern diesel plant will consume between 0.28 and 0.4 litre of fuel per kilowatt-hour at the generator terminals. With about 38.1 MJ/litre of Diesel fuel, this translates into efficiencies of 25% to 36%. In our experience, 45% efficiency corresponds to best practice at optimal operating regimes for the best commercially available equipment.
