Improve the Fuel Efficiency & CO2 Emissions of your Diesel Generators
Introduction
We increase the efficiency of diesel and gas engines
• Most diesel and gas engines are 35-40% efficient.
• The rest of the fuel energy is converted to heat, and most of it is usually wasted.
• We utilise the hot exhaust gases, converting some of the heat energy into electricity, using our unique Electric Turbo Compounding (ETC) technology
• We thus create ‘free’ and ‘green’ additional electricity.
Depending on relative fuel and electricity prices, either:
• The fuel input to the engine can be reduced, to bring the total power back to
the original level, but with lower fuel consumption.
• Or additional electricity can be sold to the grid.
Our customers include genset packagers, engine OEMs, power providers, genset fleet operators and system integrators
Who are we?
• Bowman Power is a British, privately-owned technology company, based in Southampton (UK)
• Founded in 2004 by Tony Davies OBE, a former technology advisor to Margaret Thatcher
• In-house R&D, design, manufacturing & testing facilities
• Demonstrated capability of 400 systems/year
Variety of Applications

Electric Turbo
Compounding • The TG incorporates a very compact,
high speed (>30,000rpm), high efficiency (>98%) direct drive electrical alternator.
• The TG has its own self contained oil system, providing both lubrication and cooling.
• The existing turbocharger is replaced with a high efficiency model that is correctly matched to the TG downstream to optimize the energy recovery. A separate Power
• Electronics panel provides all control functions and conversion of the alternator output to grid quality

80 - 100% COP
Bowman ETC System, tested on Cummins KTA-50 G3, 50Hz generator set at Cummins Ramsgate (UK) facility.
Example Typical Diesel genset 1275kVA / 1020kWe (Cummins KTA50-G3)
CAPEX ~ $0.3-0.5M
OPEX (fuel): $2M / year ($10m over 5 years)
If running continuously @ 80% load with diesel @ $1/litre
Genset expenses are primarily in the fuel
At 5-8% typical savings: $100-160k / year*
*Fuel efficiency and savings depend on variables such as engine type, application, utilisation and fuel price, figures in USD
