Global stationary energy storage will use 2.5TWh batteries in 2030

June 09,2023

Based on the assumption of global warming of 1.6 degrees, the total demand for batteries in different applications will increase by 15 times from the 2021 level to nearly 9TWh by 2030.

Global battery Supply Trend Chart

Rystad's calculations based on announced targets show battery supply reaching 5.5TWh by 2030. That's just enough to meet 60% of global demand, but the supply outlook is expected to change as gigafactory plans spring up around the world.

The Asian market, led by China, will account for 41 percent, or 3.6 TWh (terawatt hours), of battery demand by 2030, according to the energy research and business intelligence firm's forecasts. Europe and North America will contribute 1.9TWh and 1.7TWh respectively. The two continents are focusing on building their own capabilities to reduce their dependence on imports from Asia.

Solar cells are known to be good for the environment, but they also have drawbacks.

They are expensive to manufacture and have limited recycling options. But researchers in Australia have developed a new manufacturing technique that addresses both issues.

A solar panel usually consists of many solar cells, which convert light energy from the sun or artificial light directly into electricity through the photovoltaic effect. But the downside of making solar panels is that solar cells are very energy-intensive to produce and there are limited ways to recycle them once they reach the end of their life.

Now, researchers may have a solution. A team from Australia's Macquarie University has developed a new process for making solar cells that improves upon traditional processes, making them more energy efficient and making them easier to recycle. The latest research results have recently been published in the journal Applied Physics Letters.

Silicon is the most common semiconductor material used in solar cells. To make solar panels, silicon needs to undergo a heat treatment process called annealing, which changes its physical properties and performance. Currently, annealing is done in a furnace, requiring temperatures between 900 and 1100°C.

The researchers found that using microwave radiation to heat silicon was almost as effective as using a furnace.

Microwave heating has been widely used in rubber, ceramics, wood and other industries because of its advantages of energy saving, fast heating speed, uniformity, and economical feasibility.

It is explained that the microwave radiation selectively heats the silicon, making the annealing process faster and very energy efficient. Additionally, microwaves can be focused and used to selectively heat sections of the solar panel. And, unlike a furnace that builds up chemicals during heating, microwave annealing is clean."Therefore, there is less pollution (from the new process). The whole process can be performed at room temperature," said Binesh Veettil, lead author of the study.

Furthermore, through their microwave annealing experiments, the researchers discovered an added benefit: Microwaves can soften the plastic coating that protects the silicon plates from moisture and contamination. This means that the coating can be peeled off and the components of the board can be reused. This increases the recyclability of the solar cell.

Veettil said: "So far, the recycling methods of solar panels are still very limited. In some cases, when they are recycled, people crush them, heat them to about 1400°C, and then wash them with chemicals to remove them.

Removing the plastic is an energy-intensive process."
