Summary: The paper deals with factors influencing the cost of
electricpower produced in Wind Power Systems (WPS). Data presented aretaken
from world literature. Analyzing the examples of WPS thathave been used for
a decade both in European and in the worldpower grid systems, the
possibility of economical utilization ofwind power is shown. Comparing the
prices obtained by using WPSin the world and simulating their work on the
resources of theAdriatic coast, we conclude about the possibility of
WPSutilization on the Adriatic coast as a support to the Croatianpower
system.
The paper points out to the necessity of investing the design ofthe WPS
pilot plant at a favourable location of the Adriaticcoast or the islands.
This should be the first step towards usingnew power resources as planned
by Power Development Plan of theRepublic of Croatia up to 2010.

Summary: The paper describes the possibility of obtaining a certain
amount of electric power from wind power on the Adriatic coast and the
islands of Croatia. Analysis of resources and cost calculations are made to
show the benefits of power generation from wind turbine generators (WTGs).
The need for a systematic choice of WTGs for the particular locations of
wind power stations is pointed out. In the event of power shortage due both
to present power isolation of the Croatian Adriatic coast and the
habitually low power inflow from the existing power stations, gradual
construction of a number of WTG systems would help in periods when wind
power is available. It would contribute to quicker development of
tourism-oriented island economy and the production of healthy food.

Summary: Numerous publications around the world considering the
economicwind energy utilization, prove that it can be achieved alreadynow.
The autor of this paper set forth the presumption that areto be met in
order to achieve that aim. Partly they are in thehands of country's
economic system designers and partly in thearea of researching and
developing teams that prepare thenecessary basis. Systematic selection of
wind potential locationand WTGS is the precondition for the economic wind
energyutilization. Based on published statistics of wind
producedelectricity, grid connected WTGS are found to be more efficientthan
stand alone WTGS. The need for the same criteria whencomparing the specific
cost of energy from various sources ispointed out, as well as the
enforcement of energy production thatbenefits the enviroment protection.

Summary: Hydrogen is being considered as a synthetic fuel or
energycarrier for the post-fossil era. It has many properties tocommend
itself: it complements the renewable energy sources andpresents them to the
consumer in a convenient form at theconsumer end with higher efficiencies
than other fuels; it isrenewable; and it is the lightes and cleanest fuel.
It can beused in every application where fossil fuels are used today. Itcan
be produced from fossil fuels or from water using renewableenergy sources.
This paper contains an overview of the hydrogenproduction methods, those
being commercilly available today aswell as those which are being

design and to analyze system for the U.S. based onutilization of renewable
energy sources (solar, wind and hydro)and hydrogen and electricity as
energy carriers. The analyses ofthe solar hydrogen energy system included
enviromental effects,materials and energy requirements, and costs.
Whenutilizationefficiency and enviromental benefits are taken intoaccount,
it appears that the solar hydrogen energy systemprovides energy services at
the costs lower than those provide bythe fossil fuels or by the coal based
synthetic fuels. Thissystem is technically feassible and it could
substitute for thefossil fuels in almost every application.

Summary: Hydrogen and electricity are considered to be the
energycurrencies for the post fossil fuel era. The future energy systemfor
the U.S., based on hydrogen and electricity as energycurrencies has been
analyzed and compared with the present energysystem which is mainly based
on fossil fuels. The parametersanalyzed include: technology, area,
materials, energy and capitalcosts. The proposed solar-electricity-hydrogen
energy systemcould provide essentially the same services that the fossil
fuelsystem provides today but it is qualitatively different. It isbased on
utilization of renewable energy sources; it is notdominated by heat-to-work
conversions as it is today's energysystem, and therefore is more efficient;
it does not have anyenvironmental impact. As such, it is the ultimate
energy system,suitable for the 'low energy future'.

Summary: Environmental impacts occur during extraction of fossil
fuels,their processing and transportation, but mostly during their
enduse-combustion. It is estimated that these impacts in the UnitedStates
cause direct or indirect damage adding up to $600 billionper year, which is
more than the annual expenditures for energy.The solution to these
environmental problems is proposed in theform of the solar hydrogen energy
system. Hydrogen can be usedinstead of fossil fuels in almost every
application. Its use doesnot create any environmental problems. A
transition path throughcoal generated hydrogen is suggested, although full
environmentalbenefits of hydrogen would be realized when the solar
hydrogenenergy system is fully established.

Held: from 12/05/94 to 12/07/94
Summary: A model of PEM fuel cell performance has been developed in
order to study the fuel cell behavior in an electric vehicle, and to help
in sizing and design of a vehicular fuel cell power system. The model
consists of a set of equations that describe the main features of a fuel
cell power system and its components, such as voltage vs. current density,
active area, number of cells, operating pressure and temperature, ancillary
power requirements, fuel and oxidant consumption, air flow requirements,
heat rejection, water generation and requirements, weight and size.
Optimization criteria have been established, that include weight, size,
efficiency and simplicity of the power system. Various design options have
been investigated and the optimum design configurations selected for
further development.

Summary: This paper describes the design and performance of a
prototype zero emission electric vehicle, powered primarily by air
breathing Proton Exchange Membrane (PEM) fuel cells using gaseous hydrogen
as fuel. The fuel cell system is composed of the fuel cell stacks, hydrogen
tank, air compressor, solenoid valves, pressure regulators, water pump,
water tank, heat exchangers, sensors, programmable controller, and voltage
regulator. The battery system provides power to the vehicle during periods
of peak power demand such as vehicle acceleration or traveling at a high
constant speed. The batteries also provide the power to initiate fuel cell
startup. The vehicle has been designed, assembled, tested, and has traveled
over 100 miles solely on fuel cell power with satisfactorily performance.
It has successfully proved the concept of a fuel cell powered zero emission
vehicle. Further enhancements will improve the performance in terms of
increased speed, acceleration, fuel efficiency, range and reliability.

Summary: Transfer to the hydrogen energy system requires an optimal
solution for hydrogen storage system. A system of storing gaseous hydrogen
at room temperature and in a corresponding number of pressure vessels has
been chosen as techno-economic suitable solution. Vessels have a
cylindrical shape with torispherical heads. Expected annual amount and the
value of storage system lead us to installation of modern product line
capacity which would have a great impact on total manufacturing costs.
Modifications in a total cost of storage system, depending on the size and
number of vessels, are presented in diagrams.

Summary: The paper introduces the information technology application
to ship hull performances continuos control, based on the hull as a
subsystem of the ship. The hull of the ship incorporates all other
subsystems of the ship and provides sufficient seaworthiness to the system
- ship. Information on the hull seaworthiness now is based on periodical
surveys and maintenance, and assessments from the experience and education
of service officers. So, in navigation, there is no information based on
the actual state of buoyancy, motions, velocities, accelerations, stresses,
pressures, vibrations and deformations in real conditions. The paper deals
with the ship hull performances in typical ship activities.
