The Power Generators
Looking at the various technologies MODEC currently operates and the mission of producing clean Power with the highest thermal efficiency and lowest carbon foot-print, we initially developed the Power solution using a 30 MW Aero-derivative generator which we developed with a major USA supplier in 2008 (see Table 1 for efficiency comparison of different technologies).
Table 1. Efficiency comparison
| Description | Efficiency (%) | CO2(kg/hr/kW) |
|---|---|---|
| Oil & Coal | ||
| Turbo-Charged Engine | 48.7% | 0.448 |
| Conventional Engine | 33.6% | 0.743 |
| Coal Fired | 33.9% | 0.940 |
| Aero-Derivative Gas Turbine | ||
| Simple Cycle | 37.2% | 0.551 |
| Combined Cycle | 49.5% | 0.413 |
| MODEC Combined Cycle + | 52.1% | 0.395 |
| Industrial Gas Turbine | ||
| Simple Cycle | 34.3% | 0.592 |
| Combined Cycle | 51.3% | 0.396 |
| MODEC Combined Cycle + | 53.9% | 0.396 |
It seemed a natural fit as we currently own & operate 42 such generators which can produce roughly 43 MW (each) in combined-cycle mode. After sense-checking the market however, we concluded that we needed to develop larger “Base-Load” generators using Industrial Turbines while using our existing Aero-Derivative design for small-scale power-plants and “Peak-Shaving” applications. To this end, we have worked with major suppliers from Europe, Japan, and the USA to develop the following additional offshore “Base-Load” and “Peak-Shaving” solutions.
