övergångsbräns

Övergångsbräns, meaning "transition fuel" in Swedish, refers to energy sources used to bridge the gap between fossil fuels and renewable energy systems. The primary goal of using transition fuels is to reduce greenhouse gas emissions while maintaining a stable and reliable energy supply during the shift towards a decarbonized economy. These fuels are often seen as a necessary step in the energy transition rather than a permanent solution.

Natural gas is frequently cited as a key transition fuel due to its lower carbon dioxide emissions compared to coal and oil when burned. Its ability to be readily integrated into existing infrastructure, such as pipelines and power plants, makes it an attractive option for immediate emission reductions. However, concerns remain regarding methane leakage from natural gas production and transportation, which can significantly offset its climate benefits.

Other potential transition fuels might include certain biofuels or hydrogen produced from non-renewable sources, depending on the specific context and the criteria for "transition." The concept of transition fuels is debated, with some arguing that they prolong reliance on carbon-intensive energy and delay the full adoption of renewables. The effectiveness and desirability of transition fuels are often evaluated based on their lifecycle emissions, cost, and compatibility with future energy infrastructure. Ultimately, the aim is to phase out transition fuels as renewable energy technologies become more widespread and cost-effective.
