Cost-effective climate mitigation would reduce fossil fuel consumption in the EU by around 90 percent by 2050 compared to 2020. <\/p>\n\n\n\n

A new study by the Potsdam Institute for Climate Impact Research (PIK) shows that rapid expansion of renewable energy and widespread electrification are key drivers of this shift. The study also finds that a complete phase-out of fossil fuels by 2050 would be technically feasible, albeit with considerable effort.<\/p>\n\n\n\n

\u201cOur study shows that a cost-effective transition to climate neutrality could make around 90 percent of today\u2019s fossil fuel use in the EU redundant by mid-century. Most of this transformation can be achieved through renewable electricity and electrification, with bioenergy and green hydrogen providing additional contributions in specific sectors,\u201d says PIK researcher Felix Schreyer, lead author of the study published in Nature Communications<\/em>. This scenario takes into account all relevant technologies, and is characterised by the lowest transformation costs. \u201cA far-reaching phase-out of fossil fuels is therefore also the most economically efficient strategy for ambitious climate mitigation,\u201d Schreyer adds.

The PIK research team gives us the first glimpse of how EU climate neutrality scenarios with a far-reaching and near-total phase-out of fossil fuels by 2050 might look. \u201cWe show that even a near-total phase-out, with a reduction of up to 99 percent in fossil fuel use, is technically possible. But it would require major additional efforts and rapid growth of new technologies for producing CO\u2082-neutral energy carriers,\u201d says PIK researcher Gunnar Luderer, also an author of the study.

Advancing renewables and electrification key to phasing out fossil fuels in the EU
<\/strong>
Using REMIND, PIK\u2019s energy\u2013economy model, the researchers analyse how different energy system transformation pathways can deliver a climate-neutral EU by 2050. Their cost-effective scenario still includes around 10 percent residual fossil fuel demand, with associated emissions being fully offset through carbon capture and storage. These residual fossil fuels are mainly used in the chemical industry, as well as in aviation and maritime transport.

Achieving a complete fossil fuel phase-out by 2050 would require, in addition, a rapid and large-scale expansion of CO\u2082-neutral e-fuels: carbon-based energy sources produced from green (electricity-based) hydrogen and atmospheric CO\u2082. They tend to be expensive, but could replace fossil fuels in hard-to-abate sectors. While this approach would increase transformation costs, it would also reduce dependence on fossil fuel imports and lower the need for underground carbon storage.

\u201cDriven by technological advances in wind and solar energy and electrification, for example through e-mobility or heat pumps, a realistic and cost-effective fossil fuel phase-out is now within reach,\u201d says Schreyer. However, the authors emphasise that to effectively leverage these technological developments, near-term policy measures and investments must be consistently aligned with the long-term goal of climate neutrality. \u201cAnd every unit of fossil fuel avoided makes Europe more independent and its energy system more resilient,\u201d adds Luderer.<\/p>\n\n\n\n
