larly in heavy-duty trucks and inland water and seaborne maritime transport, in the
CEE region LNG is still undergoing its pioneering stage with obvious potential. It still
does not play the role it has along the French-Belgian-Dutch North Sea shore.
For comparison, some of the most important physiochemical properties of NG,
diesel, and petrol are listed below.
