While hydrogen is indeed a versatile energy carrier, the transportation of large quantities over long distances remains a challenge. One solution could be green ammonia as it can be conveyed and stored in a more manageable way than hydrogen.
On 18 May 2021, the International Energy Agency (IEA) presented a special report that could help implement the path to an era of net-zero emissions in the energy sector by 2050. The path to be trodden for this is narrow, but it offers amazing benefits. The report is the world’s first comprehensive study on how the transition to a net-zero energy system by 2050 can succeed globally. According to the study, the most important measures are the rapid expansion of renewable energies and the drastic reduction of fossil energy sources.
The German government has set clear targets for emissions reduction, starting at minus 40 percent by 2020, 55 percent by 2030, 70 percent by 2040, and 80 to 95 percent by 2050 compared to 1990 levels. One option to meet these targets is to increase renewable use to at least 80 percent of total market size (local electricity production and imports minus exports) by 2050. Intermittent renewable sources such as PV, onshore and offshore wind power will be crucial to meet demand due to their huge potential and will dominate any future electricity market.
