Microstructure and water distribution in catalysts for polymer electrolyte fuel cells, elucidated by contrast variation small-angle neutron scattering

By using small-angle neutron scattering (SANS) reinforced by scanning electron microscopy, the fine structure of catalysts for polymer electrolyte fuel cells has been investigated.

New fossil fuel-free plastic made of wood

Partially converting fuels into 'syngas' increases energy efficiency

Recent research from China suggests that partially converting both natural gas and coal into 'syngas' fuel for power generation can generate around 6 per cent more electricity than competing 'conventional' gasification methods.

‘Self-fuelling’ method could reduce GHGs from oil shale

A potential method for reducing greenhouse gas (GHG) emissions associated with extracting energy from oil shale has been highlighted by a recent study. A ‘self-fuelling’ method that recycles waste gas could cut GHGs emissions by 50% compared to the conventional oil shale product and 70% compared to crude oil.

Oil shale is not a viable fuel source, study says

Scientists’ best estimates of the Energy Return on Investment (EROI) of oil shale suggest it is very inefficient compared to conventional fuel and emits up to 75% more greenhouse gases (GHGs.

Fuel produced from sunlight, CO2 and water: an alternative for jet fuel?

Water and carbon dioxide (CO2) can be converted into ‘solar thermochemical fuel’ using energy from the sun and very high temperatures. A new study has analysed the production of this fuel and found that, under favourable future conditions, costs could be as little as €1.28 per litre, with close to zero life-cycle greenhouse gas (GHG) emissions. Although suitable as a substitute for any hydrocarbon fuel, it could be particularly useful as a much-needed alternative for energy-dense jet fuel.

Biofuel crops compete with wildflowers for bees

Pollination of intensively farmed, flowering crops could affect the pollination of wild plants in neighbouring fields, according to a study by German researchers.

The researchers warn that increasing cultivation of biofuel crops could possibly reduce wild flower populations.

Leaked hydrogen fuel could have small negative effects on atmosphere

Using hydrogen as an energy carrier can help reduce air pollution and greenhouse gas (GHG) emissions associated with fossil fuels, according to recent research. However, if used on a large-scale, it is important that hydrogen does not leak significantly into the atmosphere as it might have some negative environmental effects, such as increasing the lifetime of methane, increasing climate effects and causing some depletion of the ozone layer.

Changes in rainfall a consequence of clean fossil fuel energy

Implementation of technology to clean the flue gases of coal-fired power plants has significantly reduced sulphur and fine particle emissions that cause environmental damage. However, recent research suggests that plants applying this technology would emit more ultrafine particles (1-10 nanometer (nm) diameter) that affect the formation of clouds, with the unintended consequence of changing the amount and intensity of rainfall downwind of fossil fuel power installations.

Travelling slower reduces fuel consumption and nitrogen oxides emissions of ships

Ships that reduce their speed use less fuel, which lowers costs for shipping companies. The slow steaming practice also cuts nitrogen oxides (NOx) emissions. A study found that ships travelling on four European routes lowered their NOx emissions by 12% during the economic crisis of 2008/2009. Shipping continues to be a major way of transporting goods, however, and as the global economy recovers the researchers and civil society call for additional measures to reduce NOx emissions from shipping and improve air quality in Europe.

Methane emissions from LNG-powered ships higher than current marine fuel oils

Due to regulation on sulphur emissions, liquefied natural gas (LNG) has increased in use as a maritime fuel. This study measured exhaust gases from a ship with dual-fuel engines running on LNG and marine gas oil (MGO). Although NOX and CO2 emissions were lower for LNG compared to MGO, hydrocarbon and carbon monoxide emissions were higher. The authors say future work should reconsider the climate impact of LNG.
