Fight against CO2 emissions: What’s the point of a CO2 tax?
Emissions of 762 million metric tons of greenhouse gases have been calculated for Germany for 2021. This means that the country will once again fail to meet its self-imposed target of reducing CO2 emissions by 40 percent compared with 1990. The reduction amounts to only 38.7 percent. The energy sector in particular was responsible for […]
Nachhaltige Entwicklungskonzepte in Supermärkten
More and more supermarket chains in Germany are tackling measures to reduce their CO2 emissions. In addition to various projects for environmentally friendly and plastic-free packaging materials or regional production, energy balance and environmentally friendly construction are now also becoming the focus of corporate attention. The Netto supermarket chain, for example, has announced that it […]
Speichersysteme für regenerativ erzeugte Energie
Renewable energy sources such as wind or solar energy are fluctuating: Since the wind does not blow constantly strong and the sun shines stronger on some days and less strong on others (and not at all at night), both energy sources can only be used continuously and reliably if they are coupled with intelligent storage […]
Europas erste solarbetriebene Ladestation für Elektroflugzeuge
The non-profit English company NUNCATS has set itself the task of supplying remote regions in England with solar-powered light aircraft, offering an alternative to transport with diesel vehicles. Around 150 kilometers from London, a photovoltaic charging station for electric aircraft has now been set up as a demonstration facility at Old Buckenham airfield. The station […]
Neue Batterien werden entwickelt
Batteries and intelligent storage technologies are an important topic of the energy transition. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now possibly developed a new buffer storage solution for use in renewable energy generation. The so-called alkali metal iodine battery mainly consists of zinc, nickel, lithium, and graphite. Using this battery in portable devices or […]
Biomasse zur Wasserstoffproduktion
There are many ways to produce hydrogen, of which we have already presented the seawater process. But hydrogen can also be produced from biomass, as researchers at the École poyltechnique fédérale de Lausanne (EPFL) have shown using the principle of photo pyrolysis. The process can convert biomass into the fuels hydrogen, biochar and other hydrocarbon […]
Wasserstoffproduktion kombiniert mit Photovoltaik
A reliable, regional energy supply is currently the order of the day. Initiatives are increasingly being formed by large and small companies to develop attractive environmentally friendly decentralized energy generation solutions for local consumers. The German companies Lhyfe and Enerparc have now entered into a cooperation for the production of 100 percent green hydrogen in the Spreewald for local consumption. The […]

Silicon shortage – temporary or permanent?
Silicon is a crucial material for the energy transition and in digital technology, for example in chip production. The price of solar-grade polycrystalline silicon (polysilicon) fell steadily over the last 10 years, eventually reaching less than $6 per kilogram in 2020. In the same year, however, the supply of polysilicon was tightened for various reasons […]
PERC: Solarzellen aus recyceltem Silizium
Several startups and initiatives in Germany and Europe have already begun recycling valuable raw materials such as aluminum, glass, and copper from old photovoltaic modules. This is because according to current estimates, the amount of discarded solar modules in Germany alone will increase to over 100,000 tons annually by the end of the 2020s.
