Ferries to switch from oil to methanol

Swedish ferry operator Stena Line is investigating the opportunity to convert 25 of its vessels to run on methanol. The case for methanol as an alternative fuel – and the reason why Stena prefers it to liquefied natural gas (LNG) – was presented at an IMO meeting in early February.

Converting vessels to run on methanol would be considerably less expensive and complicated than converting to LNG, said Per Stefenson, a naval architect working for Stena. Methanol can be produced from natural gas, biomass – including waste – and in the future probably from hydrogen and captured carbon dioxide (CO₂). Producing it from natural gas requires about 25 per cent of the total energy compared to 10 per cent of the total energy when making LNG, meaning that LNG is cheaper and more energy efficient to produce.

Stefenson showed calculations suggesting that both LNG and methanol would have a price comparable with marine gas oil (MGO) if supplied alongside in Gothenburg, Sweden. In fact, methanol could be slightly cheaper than LNG in terms of energy supplied, and both methanol and LNG would be cheaper than MGO.

Exhaust emissions of sulphur dioxide (SO₂), particulate matter (PM) and nitrogen oxides (NOx) when using methanol are equivalent to LNG, said Stefenson.

Finding the ambition level

A tentative central ambition level for 2025 has been identified that would further reduce air pollution damage, but it is still insufficient to achieve the EU’s long-term objective of effectively protecting peoples’ health and the environment.

Editorial: Public money for public environmental goods

Potatoes, milk and bacon, almost everything we eat comes from agriculture. That is plain fact, but agriculture is also responsible for 90 per cent of the ammonia emissions and at least 11 per cent of the greenhouse gases in the European Union.

Significant cuts in carbon emissions within reach

The CO₂ emissions of the Nordic and Baltic countries can be cut by 70 per cent by 2020 or soon after, and by 95 per cent by 2030, without nuclear power and CCS, shows a new AirClim report.

Call for international nitrogen framework

A global framework on nutrients could be a way forward to address the extensive problems of pollution caused by excess nitrogen and other nutrients, suggests a recent UNEP report.

Coal pollution kills Indians

Air pollution from India’s coal power plants causes around 100,000 premature deaths every year – yet there are no national emission standards for key pollutants such as SO₂ and NOx.

Eight countries continue to exceed their emission ceilings

Car fleet dieselisation combined with high real-life driving emissions contribute to seven countries still failing to meet NOx reduction targets.

Stricter US standards for road vehicles proposed

The proposed Tier 3 standards should reduce emissions of smog-forming volatile organic compounds and nitrogen oxides by 80 per cent and particulate matter by 70 per cent, compared to today’s car fleet average standards.

Every breath we take – air quality in Europe

In the 2013 edition of their Signals report, the European Environment Agency (EEA) takes a closer look at air quality. “Signals 2013 – Every breath we take” consists of short and accessible articles covering a wide range of aspects related to air quality.

Call for long-term CO2 targets

The European Parliament Environment Committee has proposed a 120kph speed limit for vans from 2014 and 2025 CO₂ targets for both cars and vans.

Shipping should cut greenhouse gases and air pollutants

Due to its dependence on fossil fuels and the fact that it is one of the least regulated emission sources, emissions from the marine transport sector contribute significantly and increasingly to air pollution and climate change.

Stricter air pollution rules for machinery on the way

Emission standards for the non-road sector should be extended and strengthened in line with the Euro VI standards for road vehicles, environmental groups demand.

Coal costs health €43 billion a year

A phase-out of coal power generation is imperative, with a moratorium on new coal power plants as a first step.

CCS sidelined by tenuous financing

Carbon, capture and storage (CCS) has still not proven to be anything else than an inordinately expensive technology on an experimental level. Nevertheless the European Commission continues to embrace it.

Smaller carbon footprint from food

German diets have become more climate-friendly in the past twenty years, but there is great scope to reduce the carbon footprint from food consumption even more.

Europe’s dirty dozen

The most polluting point sources in Europe increased their carbon, sulphur and nitrogen oxides emissions in 2011.
