First ship engine using EGR to achieve Tier III limits

Engine producer MAN Diesel & Turbo has presented the first marine diesel engine using exhaust gas recirculation (EGR) techniques to achieve the stricter Tier III NOx emission standards of the International Maritime Organization (IMO). These standards will apply from 2016 to all new ships in dedicated NOx emission control areas (ECA).

According to MAN, this development means that strict emission limits can be met without significantly compromising engine performance – testing showed a low fuel penalty, equivalent to 1–3 g/kWh. The engine can also run in a fuel-optimised Tier II mode resulting in an approximate 4 g/kWh fuel-oil consumption reduction, which means that the engine is more efficient than today’s high-efficiency Tier II engines during transoceanic operation.

The engine will be installed in a Maersk Line C-class container vessel, currently under construction, and due for delivery in the first quarter of 2013. It has been agreed to operate the engine 20 per cent of the time in IMO Tier III mode, and to otherwise favour the fuel-optimised Tier II mode with low EGR rate.

The costs of climate change

Climate change already causes about 400,000 deaths per year and a 1 per cent loss of global GDP. By 2030 human and monetary losses may double.

Editorial: Difficult is not a strong enough reason to passively accept

Agriculture is the foundation of food production in a world that is facing the challenge of feeding nine billion people by 2050. However the agricultural sector is also responsible for significant emissions of the major greenhouse gases ..

Tighter standards for PM proposed in the US

Strengthening the annual fine particle pollution standard will improve health protection and provide benefits worth billions of dollars.

Is air quality in Europe getting any better?

In 2010, 90–95 per cent of the EU’s urban citizens were exposed to PM_2.5 levels higher than the reference values recommended by the World Health Organization.

Climate change evident in Europe

Further impacts of climate change in Europe are expected in the future, potentially causing high damage costs.

Great potential for changing behaviour

With a policy package that motivates citizens to take up a more healthy diet, replace their fossil fuel cars with electric cars and decrease room temperature, emissions in the EU could be reduced by about a quarter of the projections for the non-ETS sector by 2020.

EU greenhouse gases fell by 2.5 per cent in 2011

A mild winter in 2011 and high prices for oil and gas have, despite an increase in the use of coal and lignite, put European Union greenhouse gas emissions back on a downward track.

The Climate Bonus

Cleaner air, better health and a more efficient economy are some of the many co-benefits that we will get from investing in climate mitigation, writes Alison Smith, author of a newly published book: “The Climate Bonus”.

Air pollution burden still too high, despite improvements

To adequately protect health and the environment, air pollutant emissions need to be further reduced, according to a new study by the European Environment Agency.

Cleaner fuels will dominate in 2020

The preferred emission control options for ships trading in emission control areas (ECAs) after 2015 will be low-sulphur distillate fuel oil and liquefied natural gas (LNG), according to a study by DNV.

Increased Arctic shipping threatens the environment

Unless action is taken, the increase in shipping and other human activities in the sensitive Arctic ecosystem is likely to cause irreversible damage.
