The expected increase of hydrogen fuel cell vehicles has motivated the emergence a significant number studies on Hydrogen Refuelling Stations (HRS). Some main HRS topics are sizing, location, design optimization, and optimal operation. On-site green HRS, where is produced locally from renewable energy sources, have received special attention due to their contribution decarbonization. This kind complex systems whose hydraulic electric linked topologies include electrolyzers, buffer tanks,...

This paper addresses the energy management of a standalone renewable system. The system is configured as microgrid, including photovoltaic generation, lead-acid battery short term storage system, hydrogen production, and several loads. In this an strategy has been incorporated that pursues objectives. On one hand, it aims to minimize amount cycled in battery, order reduce associated losses size. other seeks take advantage long-term surplus energy, producing extracting from be used fuel cell...

The number of Fuel Cell Electric Vehicles (FCEVs) in circulation has undergone a significant increase recent years. This trend is foreseen to be stronger the near future. In correlation with FCEVs market increase, hydrogen delivery infrastructure must developed. With this aim, many countries have announced ambitious projects. For example, Spain objective increasing Hydrogen Refuelling Stations (HRS) public access from three units operation currently about 150 by 2030. HRSs are complex...

Standalone renewable energy systems usually incorporate batteries to get a steady supply. Currently, Li-ion are gradually displacing lead-acid ones. In practice, the choice is made without previous comparison of its profitability in each case. This work compares economic performance both types battery, five real case studies with different demand profiles. For case, two sets simulations carried out. one sets, supplied by standalone photovoltaic system and, other one, hybrid...

Standalone renewable energy is widely used to power irrigation systems. However, in agricultural facilities, electricity from the grid and diesel are also consumed. The design sizing of generation involves difficulties derived different seasonal profiles production demand. If 100% renewable, a considerable surplus usually included. This paper focused on system, which has been installed vineyard, located northeast Spain. With photovoltaic fields, wastewater treatment plant winery, drip system...

The wine sector is very sensitive to the effects of climate change. Despite this, there little use renewable energy in sector. In fact, adoption mitigation measures by companies depends on their own attitudes and interests. objective this work was understand disposition Spanish wineries incorporate energy. addition, subjective obstacles motivations for could be identified. First, a survey conducted Second, multivariate statistical technique factor analysis applied. Third, set indicators...

Climate change, depletion of nonrenewable resources in the current energies, pollution from them and greater ecological awareness population, are factors that suggest change energy sources business. The wine industry is concerned about sustainability with a clear what climate may mean for it. This sector supposed to have high receptivity implementation clean energy, as this favours not only environment but also essence its work shows how use renewable on small scale, can be profitable both...

The objective of this paper is to discover through a survey, the Spanish wine sector's attitude towards incorporating renewables. To that end, multivariate statistical technique factor analysis applied information provided by sample 87 wineries stratified regions. This resulted in set four indicators describing determinant factors (Cost, Conviction, Motivation and Investment) influencing winery's decision implement renewable energies. Furthermore, cluster three groups completely different...

For Mediterranean crops, such as vineyards and olive trees, using electric pumps for pressurized irrigation systems is typical. In both developing developed countries, the crop location frequently far from grid electricity often supplied a diesel genset. The use of renewable energy could achieve significant reductions in emissions greenhouse gases provide other advantages, cleaning, reducing operating maintenance costs, increasing sustainability. Although environment has abundant resources...

La energía utilizada en agricultura es fuente de emisiones gases efecto invernadero. Para reducir las producidas por el uso gasóleo y electricidad, proyecto europeo LIFE REWIND aborda suministro desde fuentes renovables. ello, se ha caracterizado la demanda energética recursos renovables viñedo bodega. Se buscado diseño óptimo económico medioambiental generación. instalado un prototipo una explotación vitivinícola, con generación fotovoltaica, incluyendo conjunto flotante sobre balsa. Esto...
