Solar thermal energy technical manual

We present the fourth edition of the "Technical Manual of Solar Thermal Energy". In this edition, in addition to solar, other renewable energies such as aerothermal energy, biomass or microcogeneration have been incorporated. With regard to aerothermal energy, in our...

Germany, with clear skies from coronavirus, records record solar power production

Solar panels installed in Germany generated a record amount of electricity, ending the low profitability of the remaining coal-fired power plants in the country. Clear, pollution-free skies in Germany allowed photovoltaic power plants to generate 32,227 megawatts on...

The world is preparing for the next hydrogen boom from renewable energies

The demand for electrolysers for the production of green hydrogen is increasing rapidly. 8.2 GW of future power plants are already planned, or 31 times the installed capacity accumulated today. Hydrogen from renewable energies is starting to have its heyday. As the...

Classification of biodigesters

We are talking about the different types of biodigesters that we can find. The purpose of a domestic biodigester consists in carrying out the process by which the bacteria present in the sludge naturally transform organic matter into biogas and fertilizer....

Solarchill, the solar refrigerator that saves lives

Vaccines are difficult to transport and store in areas that need them most. Solar-powered refrigerators want to fill this gap. Refrigeration of vaccines. Problems with transport and refrigerated storage (what public health experts call the "cold chain") led to "low...

Giant fuel cells to power large freighters

ABB has signed an agreement with Hydrogen de France (HDF) for the joint manufacturing megawatt fuel cell systems to power shipping vessels. The two partners wish to optimize the production of large systems in order to be able to build megawatt range fuel cells for...

How to differentiate the quality of photovoltaic solar panels?

Image: By Kampan ShutterstockThe choice of solar panel is essential to achieve a functional and efficient photovoltaic system. Below you will find a series of tips to optimize your purchase. With so many manufacturers of photovoltaic solar panels around the world, it...

Black solar tiles and facades for solar energy production

EXASUN is the Dutch company that creates solar photovoltaic PV, the panels or modules that are used in the creation of plates for the production of solar energy, the solar modules that they produce are presented as high efficiency and long lasting of life. The company...

System that allows homes to be air-conditioned from (and thanks to) the ground

Picture Shutterstock A scientific team from the University of Huelva has developed a method which, at no additional cost, makes it possible to accurately determine the heat transfer capacity from a site to a building. With this system and with the incorporation in the...

A new chemical compound that lights up the future of solar panels

Solar panels are generally made of silicon and require a minimum threshold of light to collect and store energy. Instead of using silicon, researchers have long explored the alternative to dye sensitive devices. The compound is a photosensitizer, which means that it...
