Electric vs Hydrogen: A Chinese battleground

Chinese Authorities knows it is necessary to find a solution for the pollution in their congested and bustling cities, and regarding mobility, of course the Electric and Hydrogen mobility is going to get the solution.

The question is, which is going to be better. It seems the Hydrogen will get more autonomy, even the Toyota is going to sell in 2015 a Hydrogen car (see picture) with 136HP and 500km of autonomy (on a single fillup). Regarding Electric vehicle, the idea it seem will be covering small cars for cities, but on both cases, China has not a great implementation of the electric charging or hydrogen fuelling stations.
Other countries like Norway, Tesla and Nissan are in a full competition for being the top selling monthly car (just as information: Norway Top sales: Tesla Model S in September and Nissan LEAF in October).

Of course, it will be necessary to make and study in detail about what is it happening in Norway for achieving this EV implementation, but I think China will have other situation.
China has a very big cities where the implementation of the EV needs a great investment for the electric charging, and at the same time with the hydrogen fuelling stations for Fuel Cells Vehicles.

Would be in China the solution of electric stations which  operates OFF GRID?, it could be a solution for implementing PV plants with storage systems which charge during the day (generations hours) and load the electric vehicles during night with no Grid integration, and then, saving the cost of investment the complete electric infrastucture and also, the inconvenience of the high level of harmonics whichs is generation electric stations, and of course, the implementation for getting a solution for this harmonics.

On the other hand, we will see a future where PV or wind farms in country areas generates the electricity for electric charging and for producing hydrogen to supply to the fuelling stations?

La provincia Cubana de Pinar del Rio acogerá una planta de 2.5MW

La Central Solar que podría ser ampliada posteriormente a 15MW, forma parte de los planes cubanos de impulsar las plantas a gran escala.

Cuba, la isla caribeña, con una población de 11 millones de habitantes, puso en marcha en 2006, un ambicioso plan energético buscando una solución a sus problemas de suministro debidos a una disposición de plantas Termoeléctricas con más de 25 años de antigüedad, las cuales funcionaban un 60% y provocaban cortes de suministro, sobretodo en momentos de máxima demanda, en horas pico.
Antes de la puesta en marcha de dicho plan energético, en Cuba, el consumo energético era básicamente de productos derivados del petróleo y el gas.
El plan Energético, denominado en Cuba, como "La Revolución Energética", se basaba en 5 puntos:

  1. Eficiencia Energética
  2. Incremento de la disponibilidad y fiabilidad de la Red Eléctrica Nacional (mermada en muchos casos por los huracanes)
  3. Incorporación de las Energías Renovables en el "mix" de generación
  4. Incremento de la exploración y producción de gas y petróleo a nivel local
  5. Cooperación Internacional
La apuesta del Gobierno Cubano en torno a las energías renovables parece que va encontrando su camino. Creo que la pregunta que muchos nos hacemos, es que pasará cuando el régimen, que algún día llegará, abra las puertas a la democracia y por tanto, a la inversión, está claro que Cuba puede tener una gran oportunidad en establecer un marco importante en términos de sostenibilidad, en cuando a la gestión de su recurso energético, y más concretamente eléctrico. Dicha oportunidad es más complicada en paises que ya tomarón sus decisiones, y cambiarlas requiere mucha inversión y tiempo. 
Cuba empieza de cero, pero será para bién o para, no tan bién...

Solarworld adquiere producción solar de Bosch en Alemania

Solarworld AG aquiere producción Solar de la filial de Robert Bosch GmbH (Bosch Solar Energy AG) en el denominado "Solar Valley" del este de Alemania, creando la filial denominada Solarworld Industries GmbH

Dichas plantas se centran en, producción de células; con una producción que ronda los 700MW, y de módulos; rondando una capacidad de 200MW de producción anual.

La pregunta es clara, es un paso más o el último en la reconversión del sector en Europa y más concretamente en Alemania, en una zona que realizó inversiones importantes en la Solar Fotovoltaica antes de la crisis (llegándose a denominar el "Solar Valley"), y que ve como la producción se concentra cada día más ante competencias (en algunos casos hasta desleales).

Apple 100% renewable solar Headquarter in Cupertino

Apple will have a Headquarter 100% powered by Renewable Energies in Cupertino, south San Francisco Bay Area.

The new building will combined on-site fuel cells and use of grid-purchased renewable energy during peak hours, at the same time, the new manufacturing plant in Mesa, Arizona, would also be powered by 100% renewable energies, solar panels and geothermal power source on site.

It seems two big companies of new technologies bet for renewable energies (Google and Apple)...



El agujero Eléctrico alcanza los 4.632 M€ hasta el tercer trimestre en el acumulado anual (Q3/13 YTD)

Parece que se empieza a controlar el agujero Eléctrico español, puesta que existía una desviación negativa hasta junio, en el acumulado anual, realmente está controlado o corresponde al fin de las primas de las Fotovoltaicas puesto que han cumplido el máximo número de horas primadas del año...

IEEE Approves Standard Supporting Low-frequency, Narrowband PLC and Smart-Grid

IEEE approves the updated version of 1901three years later of the first version.

Designed to specify secure PLC at data rates up to 500kbps and at transmission frequencies of less than 500kHz for applications, IEEE 1901.2 addresses low-frequency, narrowband PLC over low-voltage lines of less than 1000V between transformer and meter, through transformer low-voltage to medium-voltage (1000V up to 72kV) and through transformer medium-voltage to low-voltage power lines in both urban and in long-distance (multi-kilometer) rural communications.

Will achieved this standard the technical conditions for taking off smart grids communications by Power Lines with the properly Quality of Service (QoS)?

skytron energy ensures 115 MWp dispatchable power from Romanian solar power plants

Skytron energy is one member of AEG PS
http://www.skytron-energy.com/en/news/item/datum/2013/11/06/skytron-energy-sichert-115-mwp-pv-einspeisung-ins-rumaenische-netz-ueber-energie-dispatcher/

The skycontrol power plant controller provides closed-loop active and reactive power control and meet the special requirements of the Romanian grid system. The requirement for power feed direct by local dispatchers and the need for frequency support by providing balancing power, are now mandatory in Romania

For balancing power, the controller adapts the active power feed into the grid in response not only to changes in the grid frequency, but also with respect to the photovoltaic power plant can generate at that instant. This requieres calculating the available PV power on the basis of the plant status information provided by skytron's real-time condition monitoring system. This frequency stabilization function is unique in that it has been implemented without the need for expensive energy storage facilities. This is a first for photovoltaic power generation.
