All energy can be produced without fossil fuels already before 2050. The view is based on a recently published research article.
The Finnish LUT University, which combines technology, economics and social sciences, and 14 other international universities are proposing a new fossil-free energy system.
It would be based on solar and wind energy, energy storage, sector integration and electrification of the energy and industrial sectors based on hydrogen economy and Power-x solutions. In the future, they will also be supplemented by capturing carbon dioxide to curb climate change.
In science, an energy system based on completely renewable energy sources has become mainstream. Hundreds of scientific studies prove that a 100% renewable energy system can be achieved even before 2050 or by then at the latest both globally, regionally and nationally, the universities’ press release emphasizes.
“More and more researchers are showing that the energy demand can be met in its entirety with renewable energy sources. In the long term, it is also more affordable and in line with sustainability requirements,” sums up the LUT University professor Christian Breyer in the bulletin.
He is one of the new
-of the more than 20 authors of the research article.
“According to the UN, more than 160 companies have committed more than 70 trillion dollars to achieving global carbon neutrality, which means giving up fossil fuels by 2050. According to our research, the technology to implement a completely renewable energy system already exists,” says the assistant professor Sven Teske from the University of Technology Sydney (UTS).
According to Teske, next, new studies on a completely renewable energy system should be included in the reports of the international climate panel IPCC.
“It has been scientifically proven that a 100 percent renewable energy system is technically and economically possible,” Teske adds.
New research is still needed
New research on the new energy system is still needed, the researchers remind. Many new research topics have emerged from the broad societal debate, which are related to sector integration, smart energy systems, availability of critical materials, annual resource fluctuations, system reliability and safety, and negative carbon dioxide emissions, they list.
“The necessary technologies are already available. In several countries, it has been demonstrated in practice that it is possible to obtain synergistic benefits from energy efficiency, electrification, district heating and electric fuels,” says Brian V. Mathiesen from Aalborg University.
