[Music] one misconception is that by changing fuel you might be able to reduce the amount of NOx so that you comply with the regulation and but as long as the temperature and the pressure is high in the combustion you will still have the production of NOx so that will not actually change one solutions available to reduce the NOx is called EGR which is exhaust gas recirculation you take parts of the gas from the combustion you recirculate it and you shower it with water so that you decrease the temperature and by decreasing the temperature you will decrease the emissions of NOx as well and as you shower the water to decrease the temperature of the gases you will have water which is contaminated of course that's where the pure NOx comes into the picture pure NOx will clean the water and then you can bleed it off to the sea it's an approved system by the engine manufacturer despite of emissions if they are going out in the air or in the sea there will be regulations or requirements coming in that you can show traceability that the data is locked during the whole route so it will be important to comply because we cannot continue to do as we are doing today if you're head of other ship owners then I think that you will gain a large you [Music]
