Experimental work was carried out which allowed us to analyze the ways of solving the problems of simultaneous decrease in the consumption of conventional fuel, emission of toxic and greenhouse gases within a short time. It was shown that upgrading of internal combustion engines (ICE) operating with the conventional fuel makes it possible to meet the requirement 140 g/km CO₂; the use of alternative kinds of fuel broadens the possibility to decrease CO₂ emission and increase performance index; ICE performance with a thinned homogeneous mixture allows a substantial increase in performance index. Investigation of the operation process in ICE showed the possibility of its performance with a thin homogeneous mixtures; the performance index increases under the rated conditions from 23 to 32-34 % as a mean. It was established that power installations operating with hydrogen are able to provide zero CO₂ emission. A concept of the transition to hydrogen as a fuel in the most efficient manner is formulated.
