Energy Content is a key parameter, representing the
amount of heat transferred within the combustion chamber during the burn
process and indicates the available energy from the fuel.
As explained, higher
energy content results in higher power generation and better combustion
efficiency. The energy content has a direct impact on fuel economy and
greenhouse gas emissions, and is therefore an important parameter for Ship
Operators to consider in preparation for the EU ETS. The paper covers a range of fuel types, from 100% FAME through to
FAME blends with MGO, HFO and VLSFO.
VPS highlights that biofuels have the benefit of
reducing greenhouse gas emissions as compared to conventional carbon-based
marine fuels such as MGO, VLSFO and HSFO. However, the physical and chemical properties of
biofuels vary considerably as compared to conventional fossil fuels. In
addition, biofuels have more batch to batch and supplier to supplier
variability as they are natural products.
As a result, biofuels
have several characteristics which need to be measured to mitigate operational
problems when used on board sea-going vessels. VPS has carried out significant
research across numerous parameters that enable these characteristics to be
measured and controlled. VPS research has shown that by using these test
methods, biofuels can be used as drop-in fuels on board vessels enabling the
benefits of such fuels to be realised in the shipping sector.
This paper refers to
energy content, which is an important parameter of a fuel as it represents the
amount of heat transferred within the combustion chamber during the burn
process and indicates the available energy of the fuel. Higher energy content
results in higher power generation and better combustion efficiency. The energy content of the fuel has a direct
impact on the fuel economy and therefore greenhouse gas emissions. This
paper covers a range of fuel types, from 100% FAME (Fatty Acid Methyl Esters)
through FAME blended with MGO, VLSFO and HSFO
