1.0 Introduction
The search for a better managed human society and what brought human today threshold of civilization is as whole as man himself. The triple bottom factors of quest for knowledge, the need for production exchange, organizing power of social community – these factors have equally become interrelated and self reinforcing with each advanced technology and organization, scale, trio of energy, economy and environment and matter remaining keys to human civilization; followed by invention of language or ability to communicate, and facilitation of his mobility. All of which went through their course slowly through building stones out of stumbling blocks and some actually amazingly came out through extraordinary revolution. Likewise, all this dynamic changes through differential approach and methods which can be categorized as conventional methods of idea, hypothesis, experimentation and observation.
Over the years, time needs, growth, speed, and knowledge and of course scarcity and competition have created demand that necessitated man to build complex institution- all of which require energy to move them. Likewise vast range human development has flown precise measurement of energy and manipulation of delineated discrete object all which has no doubt reduce the crushing boarding of physical work and freed man for other pursuit. Today pollution from energy carry a very large percentage and as the carbon release has exhaust the little oxygen we are sharing and the ozone later that is protecting us from mother naturedue to lack of cogent risk assessment on systems we have been building. More so, because conventional assessment focus more on economics while environment and its associated cycle is put in oblivion, probably because of difficulties associated with uncertainties. For years many think that everything that run air is infinite, the atmosphere and the ocean is providing us source of freshening, winds and current are far more vulnerable to polluting activities that have run off into them too many poisons that the air and the ocean may cease to serve more purpose if care is not taking to prevent pollution. To this end the challenge of air emission is recognized to:
Be main inherent consequence of powered shipping Have link to fuel oil burning as main source Have links with continuous combustion machineries – boilers, gas turbines and incinerators
This paper will discuss how the challenge climate change, ozone depletion , global warming touched engineering including engineering requirement of ship operation and the impacts of emission from ship, rising egalitarian techno economic and environmental sustainable abatement method to reduce and control emission. As well as matching development and improvement necessary for energy efficiency and performance of new propulsion system ( all electric ship for short sea shipping and hybrid gas electric system for high sea shipping) through comparison and simulation of extreme conditions.
2.0 Emission Ride on Ship Technology
This issue of environment become so sensitive recently with respect to infrastructure development and most especially in everything we use energy for because most of the past polluting activities has turned into poison through point form effect and are presently having advert effect on our in quality of air and water. In a nutshell, the three worlds we live are currently are out of balance and in potential conflict and man is in the middle. Historical records of number of calamity that has resulted to heavy lost and pollution are calling for news and philosophy of doing things through assessment of economics and environmental issue relating to energy, without compromising to the later has a lot of case have been based. This is already equally calling for a number of regulations, that will subsequently affect, policies change and procedures relating to the above and their effect to design of new systems and modification of existing one.
In regards to energy, It all started with environment natural source of energy,-animal, windmill, watermill, then steam, electricity and nuclear, with so much water and wind and even the sun all of which are the primary source of energy that goes through natural circle to support human life and the planet, the remain the leanest inherited resources, new technology has not turn this vast potential income into usable supplies- for years the

Cleanest and the safest are among the inexhaustible, the use of energy is likened to reckless try and error, experimentation, and age that discover the big gap between renewable and non renewable energy, and how human have adventurism has lead to replacing renewable natural given of nature by non renewable and associated backlash has called for new ways to do things and importance of using advantage of nature and its given. Renewable source of energy range from energy from the sun, hydrogen and biomass- as for the later, using waste to produce biomass is very. reasonable than growing crops that suppose to be used for food to produce energy or else we end up breaking the food chain and when scarcity of products involve come we all have to pay for it anyway. I am not going to discuss much about renewable source of energy or green house gas today. Land based technology will required to be transfer sympathetically to the marine industry via availability of engines, systems and technical assistance. Marine craft operation in inland water operation requires fuel supplied in bulk rendering the NG distribution viable. The use of an alternative fuel for vessel propulsion will leads to a design review of Power plant, associated fuel system and propulsion train; effectively reshaping areas such as Machinery Arrangement, Hull Form, Compartmentation, Cargo Deck, Payloads, Superstructure, Interior Layouts,
