The research presented here has been conducted in the Smart Charge project. It has addressed the use of renewables, e-mobility and battery charging in the Arctic as part of an effort to solicit fossil-fuelled alternatives. Of particular interest has been to determine what impact and support electric snowmobiles can provide together with local, renewable energy production. The relevance of vehicle-togrid/ building (V2G/B) solutions have been investigated in the project too. The idea has been to use electric snowmobiles for load shaving during extensive periods of the year. The research has looked at cost aspects, value stacking, climate impact as well as aggregated effects of controlled fleet management of idle snowmobiles. A case study undertaken at Longyearbyen at Svalbard, Norway has provided the most important empirical basis for the research presented. The research concludes that electric snowmobiles can have a positive effect on the local energy system and despite limited range can be quite attractive for the individual to operate if energy for charging is based on local driving solar power.

Nowadays, wind energy systems are the most efficient systems of all renewable energy production systems. Therefore, all sizes and types of this kind of systems are available, but there are few portable systems which can be temporarily mounted in certain isolated areas. We propose in this case study another solution as an alternative: an adaptable mechatronic system which can withstand even in very difficult and challenging weather conditions due to their active surfaces that have reconfigurable automatic structure.

This work focuses attention on the evaluation of global energy balances of an agro-energy system based on a diesel engine fuelled with rapeseed oil integrated with a steam plant fuelled with the residues of rape cultivation. The agro-energy system has been separated into the stages of in-the-field cultivation, transport of products to the industrial plant, and conversion into electric power. For each stage, inputs (fuels, electric power, fertilizers, and so on) and energy outputs (oil, electricity, residues, and by-products) are evaluated. Integration between the engine and the steam plant is implemented through thermal recovery of the engine exhaust gases and cooling fluids (supercharging air, lubricating oil, engine jacket cooling water) to preheat the boiler feed water. The results of the study show that the recovery of thermal energy made available by the diesel engine leads to an increase in steam plant conversion efficiency of more than three per cent (from 25.1 per cent to 28.4 per cent). In other words, energy recovery leads to an equivalent efficiency of the engine over 56 per cent, which is more than nine points above the efficiency of the diesel engine alone. In addition to the sole use of vegetable oil for energy production, the use of straw makes it possible to double net energy production per unit of cultivated area. Implementation of this agro-energy chain provides a net energy production of 55–60 GJ/ha, an energy output—input ratio around 3.0–3.3, and a primary energy saving of about 65–70 per cent compared to the use of fossil fuels.
