In the first half of 2018, wind farms in Germany fed around 55 billion kWh into the power grid. 7 billion more than in the same period last year. Scientists are working to improve conversion and storage technologies to temporarily store surplus wind power. The current BINE Projektinfo “Energiepark Mainz” (05/2018) presents a promising process by way of the world's largest Power-to-Gas research facility. Electrolytic hydrogen is produced using wind power, and is then stored and fed into the natural gas network. The aim is to test the processes and novel components on an industrial scale.
Power-to-Gas plant at Energiepark Mainz with positive interim results
Systems based on polymer electrolyte membranes (PEM) are used in the electrolytic production of hydrogen at Energiepark Mainz. In the research phase, systems with peak loads of up to 2 MW were used for the first time. At the beginning of the project, the typical output of PEM electrolysers was around 100 kW.
The advantages of this membrane electrolysis method are that the hydrogen involved is very pure, the process requires little maintenance and it can react well to fluctuations in the power grid. In Mainz, the gas is compressed with ionic compressors, stored and fed into the natural gas network or delivered to hydrogen filling stations and industrial plants.
Hydrogen is a versatile chemical energy storage medium and base material. Up to 10 % hydrogen can be added to natural gas, and it can be used directly in industrial production processes while being easy to store.
The electrolysis plant generates up to 1,000 Nm³ of hydrogen per hour, which is fed into the natural gas network for the Mainz-Ebersheim district. The energy park completed the research phase in 2017 and has started normal commercial operation.

About BINE Information Service
Energy research for practical applications
The BINE Information Service reports on energy research topics, such as new materials, systems and components, as well as innovative concepts and methods. The knowledge gained is incorporated into the implementation of new technologies in practice, because first-rate information provides a basis for pioneering decisions, whether in the planning of energy-optimised buildings, increasing the efficiency of industrial processes, or integrating renewable energy sources into existing systems.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.

Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
