Natural gas turns to liquid when cooled to – 162 °C, yielding LNG, Liquefied Natural Gas. LNG is a mere 1/600 of its original volume. This is how a lot of gas fits in the tank. Trucks and buses can cover over 1,500 km with LNG at running costs lower than diesel.
LNG is the clear winner in terms of climate credentials: 15% less CO2, 50% less noise,50% less nitrogen oxides and almost no sulfur oxides or particulates compared to diesel make a compelling argument for LNG on the road. Additionally, processed biogas can be mixed with the fuel LNG to further reduce CO2 emissions. Adding 20% processed biogas, for instance, improves an LNG-truck’s environmental performance by up to 24%. No other technology offers this tried-and-tested, realistically available and regional perspective. Investing into gas mobility also secures the option to integrate and use renewable energy sources in the future.
Here’s the most important part: LNG is currently the only viable alternative for long-distance truck and bus travel. The same holds true for shipping. No battery has yet been invented that can compete with the range of LNG in the size of a fuel tank.
So far, the sparse CNG filling station network has been the biggest deterrent from using LNG as a fuel. Until 2020, the EU aims to increase the share of non-oil fuels in consumption by at least 20%. Reaching this target on time is not possible with conventional fuels alone. That’s why governments are considering LNG for heavy transport on land and sea.
OMV supports the processing of this environmentally friendly fuel and will continue to develop and assess new and economically sustainable business models in the promising area of small-scale LNG for transport.
