the same time, different ionic liquids with higher temperature stability should be selected
for composite preparation. Such materials will find application in medium range PEM
fuel cells. In this work, only biodegradable ionic liquids were used for composite
preparation.
Hydrogen application research: Combined hydrogen, heat and power system is
designed for Academic Centre of Natural Sciences (the territory of new Campus of
University of Latvia), based on DFC300 power station (J.Dimants et all, 2012). Fuel
supply to DFC300 is planned in three stages: 1) natural gas from city pipeline; 2) locally
produced biogas mixed with natural gas from city pipeline; 3) only locally produced
biogas mixed with synthesized on site methane.
Fuel cell power station as installed serves as the primary power source for Academic
Centre of Natural Sciences, as an emergency power source for Academic Centre of
Natural Sciences when the grid service is not online, as heat supplier to pre-heat the
Academic Centre of Natural Sciences in winter season and hot water supplier to
technical and service needs. Wind power and solar PV units are connected in grid and is
powering electrolyser to generate additional hydrogen for CO 2 +H 2 reactor to recover
carbon dioxide from DFC300 exhaust. Hydrogen has a potential becoming a key factor
in driving energy system to a sustainable trajectory. Hydrogen usage in stationary and
mobile applications without damaging emissions is highly regarded. By using hydrogen
energy, the end user can contribute in maintaining long-term energy stability. Public
acceptance and knowledge expression is a substantial factor in order to implement
renewable energy projects. Main results of survey show that majority of the respondents
are very positive about renewable technology implementation idea in the University of
Latvia Academic Centre Of Natural Sciences. Nevertheless many respondents are highly
concerned about safety issues of the renewable energy technology. This means that
safety education must be implemented and discussed more with society. As well as
students and future students strongly agree that access to renewable energy technologies
in the campus area during studies is an important part of student practical training.
Students, academia as well as future students does support implementation of renewable
technologies to improve the quality of learning, sustainable development of the
university campus and green life style.
