Half of the world’s emission reductions will require commercially unavailable technology

If the world expects to eliminate carbon dioxide emissions by the middle of the century, nearly half of the reductions will have to come from existing technologies today.

This discovery, in a report The International Energy Agency, released on Tuesday, said it needed to make an aggressive investment in research, development and expansion of clean energy technology.

The IEA’s roadmap for eliminating energy-related emissions by 2050 — and allowing the global temperature to rise to 1.5 ˚C — plays key roles in technologies that are now virtually non-existent or very expensive today. These include much more energy-efficient batteries, clean hydrogen as a fuel or food for industrial processes, liquid biofuels for aviation, and equipment that receives affordable carbon dioxide emissions from factories and gas or coal-fired power plants.

The report emphasizes the need for significant investments in carbon dioxide extraction equipment. These include direct air trapping machines, which are now very expensive and known as bioenergy for capturing and storing carbon (or BECCS), which we can use as plant material as fuel and capture emissions from combustion. .

IEA findings are a topic of discussion that should focus on creating new technologies to combat climate change in the world or spreading them aggressively.

John Kerry zar US climate caused a line reaction Speaking to the BBC over the weekend, “Scientists are telling me that 50% of the cuts we need to make to get to zero will come from technologies we don’t have yet.”

For its part, the IEA has described them as technologies that are “currently in the demonstration or prototype phase” or “not yet commercially available”.

But the report makes it clear that the world has no choice between innovation or expansion. It sets a timeline that shows how fast we need to build the technologies we already have to meet the mid-century goals.

By 2030, the world needs to add more than 1,000 gigawatts of wind and solar energy each year, which is the entire electricity system In the US today. Electric passenger vehicles are expected to reach 60% of new sales by 2030, and half of the heavy trucks purchased must be EVs by 2035. And by 2045, half of the world’s heat demand must be met by heat pumps, which can run on clean electricity.

In short, we need to make rapid progress, all together.
