see this blog post<\/a>, among others). But no matter which future scenario, on average some objectives emerge. We would have to achieve some of these by 2030, in order to have a realistic chance of achieving a climate-neutral energy system. According to the study’s calculations, we need to implement these five points in the next ten years in order to have 95% compatibility. However, the rule of thumb is always: the sooner the better, in order to be able to achieve the 1.5\u00b0C as well:<\/p>\n\n\n\nI. Rapid Reduction of CO\u2082 Emissions in the Power Generation Sector<\/h2>\n\n\n\n
For sector coupling to be meaningful, a CO\u2082 factor below 200g\/kWh would be required for the production of electricity in 2030 (today around 414 g\/kWh). To achieve this, the capacities of renewable energy sources must be massively expanded. This would mean doubling the current capacity of wind turbines and photovoltaics up until 2030.<\/p>\n\n\n\n
II. Short-term Storage on a Grand Scale from 2025 Onwards<\/h2>\n\n\n\n
The expansion of fluctuating, i.e. not always available, renewable energies will increase the importance of both flexibility and storage systems in the energy system over the next five years. This involves “intermediate parking” of the electricity.<\/p>\n\n\n\n
III. Large-scale Electrolysis from 2030 at the Latest<\/h2>\n\n\n\n
The use of electrolysis in the production of hydrogen from renewable energies in the GW range will also gain importance in ten years’ time. An environmentally friendly, “green”, production of hydrogen will then be used in the industrial and transport sectors (such as shipping and freight transport). The first pilots and demonstrators represent the starting point for this process.<\/p>\n\n\n\n
IV. 15 Million Electric Vehicles in Road Traffic<\/h2>\n\n\n\n
By 2030 at least 15 million gasoline and diesel vehicles in Germany should be replaced by electric vehicles. In addition, other transport concepts, such as public transport or rail transport, must also be further developed and used.<\/p>\n\n\n\n
V. 12 Percent of All Installed Heating Systems are Heat Pumps<\/h2>\n\n\n\n
Also in the field of building heating a lot would have to be done by 2030. An increase in the renovation rate to at least 1.5% per year and a parallel expansion of heating networks. In addition an increase in electric heat pumps is necessary. Heat pumps – which will become the primary heating technology – must already account for 12 percent of all installed heating systems by 2030. The reason being that they integrate well into a renewable system by using electricity.<\/p>\n\n\n\n
