论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。Gas engines have during the years been a derivate of the diesel engine development. The developed Diesel engine families have given a reliable and cost effective platform for developing gas engines. By adapting gas technologies to existing platforms the development time has been significantly reduced which has led to reduced lead times and cost competitive products. The first Wärtsilä gas engines were introduced to the power plant market driven by the fuel price, operational flexibility and emissions. The awareness of utility companies has increased and gas engines are considered reliable, flexible, and efficient and cost competitive energy converters. Yearly globally electricity demand grows with a speed of 10 to 15 %. Renewable fuels have gained momentum and will stand for 20% of the total production. The main challenge with the renewable energy is related to availability and predictability. Big wind mills producing 500 MW might lose there total power in a few minutes’ which needs to be compensated. Traditional coal and turbines can not cope with this rapid power demands, if starting from standstill. Shipping is facing tough emission restrictions in 2016 when the requirements on fuel quality and NOx emissions will be introduced. Gas engines will be a competitive choice as the availability of gas is improving especially in the ECA areas. The use of gas engines in the Merchant and Offshore segments is already a standard as the first installations for cruise and navy are under delivery. This paper will describe in addition to the reliability, output and lifecycle cost improvements a summary of challenges like engine loading, methane slip and how they have been tackled. The paper is shared in 2, one reviewing the diesel and one reviewing the gas in more detail. To be noted however that many technologies naturally can be applied for both.
