Total Subsidiary Uses Photovoltaic Energy Storage System For Battery Utilization

- Nov 15, 2019-

According to foreign media reports, France's Total subsidiary TATES, a subsidiary of France, announced that its second-generation lithium-ion battery for solar lighting plans will be used by startup Aceleron for energy storage in residential solar installations. In the system.

Total Access to Energy Solutions (TATES) sells solar luminaires and kits in emerging markets around the world with the goal of selling 6 million “home and community solar decentralized solutions” by 2025, which will power approximately 25 million people.

Although lithium-ion batteries are still in the early stages of recycling and secondary use, the potential for both supply and demand may be large.

And Aceleron is a UK-based startup. The company's CEO, Amrit Chandan, called the solution "simple assembly technology" on the site's blog, which is easy to replace parts and has advanced machine learning capabilities to identify which battery components have failed.

The two companies initially invested £51,000 ($65,910) and Aceleron converted the lithium-ion battery supplied by TATES into a secondary battery at a cost of $45 per kWh. These batteries are expected to last for another seven years in energy storage applications, while the energy storage system in Kenya uses a secondary battery cost of $6.50 per kWh. According to Aceleron, lead-acid batteries are twice the price ($12 per kWh per year) and can only be used for three years.

This investment will benefit some residents of Kenya, Benin, Rwanda and Libya who do not have access to the grid. TATES said it will use its existing network to encourage other companies to provide secondary lithium batteries for the project. Aceleron CEO Amrit Chandan said in an interview with the media that the project will soon "go into the scale implementation phase", which will be finalized with TATES.

Chandan said, “The approach we take is to reuse all resources as much as possible, reduce the carbon emissions from battery production, to maximize the value and offset all the energy used in production. Finally, the discarded batteries are recycled.”

The startup has assembled 150 secondary batteries from 5,000 used batteries supplied by TATES, for a total of 4,500 batteries. Chandan said the company's business model also emphasizes building a value chain that, although currently assembled in the UK, can be maintained and repaired at the deployment site.

Adequate supply of secondary batteries

According to a recent study by consulting firm Circular Energy Storage, many people underestimate the potential quantity, supply and reusability of secondary lithium batteries, especially lithium batteries from the automotive industry. It is expected that by 2030, China will dominate the $45 billion lithium-ion battery market. The study also set the cost of secondary batteries at $45 per kWh, which is in line with Aceleron's and TATES project offers.

Although the initial transaction with TATES and its partners is small, Aceleron CEO Amrit Chandan believes that the supply chain for secondary lithium-ion batteries is still evolving and there will be no shortages in the short term.

Chandan said. “In Kenya and other African countries, we are negotiating with companies that have a lot of batteries. They can replace 400 to 1500 battery packs per month, and in large-scale battery applications, even if the lithium-ion battery is of good quality, There are some wear and tears that we need to pick for this."

He said that some electric car manufacturers are not sure how to handle the inventory of secondary batteries, which is another motivation for Chandan and co-founder Carlton Cummings to create Aceleron.

He said, "Therefore, the supply of secondary batteries is not a problem, and market demand is definitely not a problem."

From solar lighting to production electricity

Home suppliers of solar power systems or microgrids, including Zola Electric, Powerhive and Qinous, understand the trends in solar + energy storage solutions in emerging economies. This solution not only provides lighting, but also provides mobile phones. Charging and other powering features. Mobile payment systems and pay-as-you-go technologies are also widely used in Africa, and Powerhive's Daniel Porras said in an interview in 2017 that the African market is willing to accept new technologies for rural electrification. Although Aceleron has not yet launched an "energy as a service" product, its CEO, Amrit Chandan, said the market has broad prospects.

Chandan said that the price of lithium-ion batteries has been declining, and the increased demand for electric vehicles has prompted the mass production of lithium-ion batteries is a major cause, in addition to the energy storage system deployed in residential solar power systems. As the feasibility of deploying these systems increases, so does its size.

As electrification advances, it is hoped that battery-based energy storage systems can be used to power their businesses, not just for homes. We also see that it is now at a turning point. There are still many companies that are adopting lead-acid battery systems, but have begun to switch to lithium-ion battery energy storage systems, and they hope that this solution will not only be cost-effective, but also be able to be recycled at the end of their useful life.
