ESS Inc becomes 'US' first publicly-traded long-duration energy storage company' 12 October 2021. ESS Inc is the holder of proprietary technology which makes the Oregon-headquartered company the only provider in the world of a flow battery based on an iron and saltwater electrolyte.
In an interview for Energy-Storage.news in late November, US national Energy Storage Association (ESA) CEO Kelly Speakes-Backman said that 2021 will be an “important year for energy storage” and that the industry will continue to grow at an accelerated rate – with at least 3.6GW of storage expected to come online.
Research firm Wood Mackenzie Power & Renewables found that in the third quarter of 2020, 467MW / 764MWh of energy storage was deployed around the US across all market segments.
For the US energy storage industry, still the world's leader in adopting batteries for the grid and for renewables, it has however been a year in which clear steps forward have been taken.
According to the China Photovoltaic Industry's Association, solar installations in China should reach 55-65 GW in 2021, up from 48. 2 GW in 2020 and surpassing the record set in 2017.
All in all, China made a total of 340 GW of solar wafers, 170 GW solar cells, and 160 GW of solar module capacity in 2021. The strong outlook for solar PV installations in China is basically based on the development of the solar industry development over the last 10 years.

China is expected to install a record amount of solar power in 2021 as the industry continues to benefit from green policies in the country, which already has the world's largest fleet of panels. What is Happening?
According to the National Energy Administration, a total of 53 gigawatts of solar PV capacity was installed in 2021, which is close enough to the high record hit in 2017. Half of the solar PV installations came from rooftop installations.
The country's total solar capacity reached 306 GW at the end of the year, with 107.5 GW of distributed solar (+29 GW in 2021, i.e., around 55% of all new solar PV capacity added in 2021). More than 40% (21.5 GW) of the total capacity corresponded to residential solar plants (compared to more than 10 GW added in 2020).
The strong outlook for solar PV installations in China is basically based on the development of the solar industry development over the last 10 years. Between the 2011 and 2020 period, China is recognized as one of the leading global solar PV pioneers.

[PDF Version]In this investigation, two electrorefining... The recycling of lead acid batteries (LABs) comprises relevant concerns on the suitable methodologies to recover lead. In this investigation, two electrorefining processes, by using acidic and alkaline electrolytes, have been compared to determine the most significant results of both methodologies.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
Lead acid batteries are processed mainly by using pyrometallurgical operations with problems related to SO 2 evolution. Many efforts have been devoted to solving this concern. In this work, where only the anode preparation was a pyrometallurgical process, this problem has been overcome by limiting the process temperature.
The technical challenges facing lead–acid batteries are a consequence of the complex interplay of electrochemical and chemical processes that occur at multiple length scales. Atomic-scale insight into the processes that are taking place at electrodes will provide the path toward increased efficiency, lifetime, and capacity of lead–acid batteries.
Batteries use 85% of the lead produced worldwide and recycled lead represents 60% of total lead production. Lead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered.
In principle, lead–acid rechargeable batteries are relatively simple energy storage devices based on the lead electrodes that operate in aqueous electrolytes with sulfuric acid, while the details of the charging and discharging processes are complex and pose a number of challenges to efforts to improve their performance.

In addition the micro grid could make use of modern technologies of electric power generation like electric storage devices and CHP's (Hartkopf & Erbato, 2011). Improving the power quality.
The main source of electricity in Ethiopia is from hydropower, with 1850 MW installed. The power is distributed mainly through interconnected system (ICS), this is the main grid. A small part is distributed through self contained system (SCS), small mini grids ( Ministry of Water and Energy, 2012).
Therefor it requires a legal framework to facilitate international cooperation (Eberhard & Shkarton, 2012). As widely known, the weaker the grid, the more worse the PQ. The Ethiopian grid and the generation capacity is expanded quickly in the last years and continues growing in the upcoming years.
The integration of the power systems of the members will enable Ethiopia to invest in the large hydropower resources it possesses, for export to the neighboring countries. Currently Ethiopia is forming interconnections with neighboring countries, like the Ethiopia-Kenya electricity highway with HVDC.
Ethiopia is experiencing increased energy consumption and demand. To meet these demands Ethiopia by providing sufficient and reliable power supply that meets international standards. This will be achieved by accelerating and completing the construction of hydroelectric power and other energy generation projects.
Energy is one of the essential components for development and in reducing poverty, which is one of Millennium Development Goals (MDG). The challenges in Ethiopia are common in many other countries in Africa, few households have access to modern energy (including electricity), poor reliability and power quality of the electrical grid.

Hydrogen gas production occurs during the charging process of lead-acid batteries due to electrolysis. When the battery undergoes charging, the electrochemical reactions split water molecules in the electrolyte, releasing hydrogen gas at the negative plate.
The gases given off by a lead-acid storage battery on charge are due to the electrolytic breakdown (electrolysis) of water in the electrolyte to produce hydrogen and oxygen. Gaseous hydrogen is produced at the negative plate, while oxygen is produced at the positive. Hydrogen is the gas which is potentially problematic.
This hydrogen evolution, or outgassing, is primarily the result of lead acid batteries under charge, where typically the charge current is greater than that required to maintain a 100% state of charge due to the normal chemical inefficiencies of the electrolyte and the internal resistance of the cells.
The chemical reactions that generate gas in lead-acid batteries involve the electrolysis of water and the formation of gases, primarily hydrogen and oxygen, during charging. The understanding of these reactions highlights the complex interplay of chemical processes in lead-acid batteries.
Oxygen gas production is another byproduct during the charging of lead-acid batteries. This gas is released at the positive plate during the electrolysis process. The evolution of oxygen can contribute to the overall efficiency of the battery charging process but poses further safety risks if not properly ventilated.
According to a study by Tarascon and Armand (2001), hydrogen gas is highly flammable and can form explosive mixtures with air. Oxygen gas production is another byproduct during the charging of lead-acid batteries. This gas is released at the positive plate during the electrolysis process.
