It has been established that emissions and wastes from the operation of motor transport are one of the most common sources of air pollution and ecological imbalance. Despite the significant number of documents on the greening of motor transport in Europe and the world, the need to reduce the negative impact of cars remains open. A possible solution to this problem is the use of hydrogen as a fuel and as a cleaner for internal combustion engines. The expediency and efficiency of the application of hydrogen technologies to reduce emissions of carbon dioxide, soot and other compounds by internal combustion engines of road transport are substantiated. The possibility of application of hydrogen technologies for domestic motor transport to ensure European standards of its operation is determined. The experience of developing an innovative system of hydrogen purification of internal combustion engines with a long period of operation, proposed by the specialists of the Science Park of the Lviv Polytechnic National University "SID Sity" (Lviv) is analyzed. The proposed development provides improved technical parameters and is cheaper to operate compared to foreign counterparts. The proposed hydrogen purification system can meet European standards of environmental requirements.

The conceptual approach to business modeling of intellectual and innovative (IIT) enterprises is substantiated. The author's approach is based on the component principle, based on the application of systems methodology. To form it, the following tasks were set and solved: 1) to establish the target function of the business modeling system - a function that connects the goal with controlled variables in the optimization problem - creating new economic value on the basis of business model formation for IIT; 2) to analyze the current, recognized in the world business practice, approaches to business modeling of enterprises, to identify their basic components; 3) to form a system of business modeling of IIT enterprises, which would be based on the basic components of business modeling and take into account the features of IIT. The proposed conceptual approach to business modeling of IIT enterprises differs from existing features: the basis of the approach is based on the model of systems that allows to take into account and interconnect many components of business modeling, united by a common goal, to detail specific aspects of IIT enterprise, identify "bottlenecks" and prospects for development; the target function of the business modeling system is established - the creation of new economic value on the basis of forming a business model for the IIT enterprises; the main components of business modeling are systematized by the following key blocks: key processes, key components, evaluation of the business model, which contributes to a clearer perception of the elements of the business modeling process and better implementation.
