The share of renewables in electricity generation in Germany is to be at least 80 percent in 2030. This is a central promise of the so-called Easter Package presented by Economics Minister Robert Habeck. GES has done the math and concludes that the target cannot be achieved. Unfortunately, there are considerable gaps in the paper […]
MehrAn excerpt: “We welcome the flexible cycle model pursued by the association, which does not name fossil fuels per se as the core problem, but the burning of these fossil fuels in such way that CO2 is released into the atmosphere. As far as possible this must be prevented. Hence, the focus is on technical […]

Dii Desert Energy is the successor organisation to Desertec. Dii and GES share a similar view of the global energy transition. A quote from the joint paper: “Global Energy Solutions and Dii Desert Energy are not only focusing on green electricity, but also on the conversion to hydrogen and its derivatives. In addition, liquid organic […]

Into the ground instead of into the atmosphere, that is the principle of Carbon Capture and Storage (CCS). The CO2 produced by industrial processes is captured, concentrated and injected into caverns, for instance. Internationally, this is regarded as a safe method of storing CO2 in an environmentally friendly way. Another method is the injection of […]
MehrRussia’s attack on Ukraine in violation of international law is a historic turning point. After many years of peace, war is once again raging in Europe. The Ukrainian civilian population is suffering, hundreds of thousands are fleeing. The consequences of all this are not foreseeable, neither militarily, nor politically. Energy policy is already reacting, not […]

Global electrolysis capacities are increasing rapidly from very few capacities available today. Europe leads the way in terms of planned projects, followed by Asia and North America. However, there are still considerable hurdles to a broad market ramp-up: high costs for investments and electricity, possible raw material bottlenecks and a lack of standardisation in production. […]

According to the common hydrogen colour theory, green hydrogen is produced by water electrolysis. Only electricity from renewable sources is used in this process. Grey hydrogen is usually produced from natural gas. It is broken down into hydrogen and CO2 by heat (steam reforming). In the process, CO2 is released into the atmosphere. Blue hydrogen […]

This is how much CO2 is produced creating one tonne of concrete. Whereby the production of burnt lime for concrete is the main source of emissions. The calcium carbonate of the limestone is converted into calcium oxide. The proportion of binder (clinker) in concrete can be reduced, but concrete production will not become “green” this […]

A new paper by Global Energy Solutions also fits in with Katherina Reiche’s discussion on the “colour theory” of hydrogen. It deals with the production of turquoise hydrogen by means of methane pyrolysis. This process does not produce any CO2. If methane from biogenic sources is used instead of natural gas, even negative CO2 […]

In a study, Oxfam criticises the CO2-intensive lifestyle of the super-rich. According to the study, the wealthiest one percent of the world’s population is expected to account for 16 percent of total CO2 emissions in 2030. The inequality of rich and poor in terms of CO2 emissions should be at the centre of the debate. […]
