Here’s an intriguing idea: Don’t burn off most waste gases produced by steelmaking but turn them into basic chemicals and capture the carbon dioxide they contain instead of discharging it into the air. It is an idea with only one caveat, in that it will most likely take another 15 years before industrial-scale systems are available. Still, thyssenkrupp has taken the first step by starting its Carbon2Chem® project in Duisburg in mid-September. (more…)
Eco-gas such as hydrogen or methane produced from renewable electricity is widely regarded as central to effective climate change policy. But if the latest predictions are any indication, Germany will need to import most of it. This doesn’t bode well for a shift in attitude, as much of the natural gas consumed in the country is shipped in from abroad as well. It is doubtful that continuing the practice with eco-friendlier imports (more…)
Producing hydrogen in a completely natural way is something of a Rosetta Stone in science. Many have tried over the past decades, but rarely have they been able to announce a breakthrough in this field. Electrochaea, a startup based in a town west of Munich, could now have taken a big leap toward economic feasibility. This spring, the 20-staff company declared its intention to build power-to-gas bioreactors with a capacity of up to 50 megawatts. (more…)
Considering the highly ambitious GHG reduction targets that both the German government and the European Union have announced for 2050, it seems hardly enough to transform only the electric power market. Each part of the economy must see dramatic changes if the goal is a zero-carbon future. This also includes the steel industry, which produces around 6 percent of the carbon dioxide emissions in Germany (more…)
Even if renewable hydrogen is not yet economically viable, there have been some demonstration projects to test its general suitability outside simulated environments. One of these research endeavors is the EU’s GrInHy, in which a consortium made up of eight companies based in the Czech Republic, Germany, Italy, Finland and Spain have been working together to make an RSOC, that is, a reversible solid oxide electrolyzer (more…)
In the 1960s and 1970s, the UK put in enormous efforts to replace the ubiquitous town gas with natural gas supplies. The former, manufactured locally, contained more than 50 percent hydrogen. The proportion dropped to zero once the network was converted and about 40 million appliances were adapted for natural gas, delivered from the country’s North Sea fields. But today, something old could be new again, as one city is planning to switch its pipeline system to pure hydrogen and serve as a model for the rest of the country. (more…)
