Energy storage trends and possibilities are quite diverse today, as new trends and technologies are being developed and improved. In general, energy storage is an important tool to ensure the effective integration of renewable energy sources and unleash the benefits of solar and wind energy for emerging markets.
According to the latest in technology news, today, the key problem of renewable energy is that powerful energy storage devices are needed that can store excess electricity for a long time. This need creates a new trend for the creation of improved energy storage devices.
Many experts expect China and India to become the biggest energy storage markets in the next decade, fueled by these countries’ progressive renewable energy goals. Latin America is also a promising market for developing energy storage plans. Regarding South Africa’s future, energy storage can be fueled by the bigger introduction of renewable energy sources.
In the Middle East and North Africa, some countries are also seeking to use bigger amounts of renewable energy to reduce the number of local fossil fuels used for local electricity generation, freeing those fuels for sale abroad, generating revenue for government programs.
Meanwhile, Australia’s CEP Energy said it will build the world’s largest battery network on the continent. She will be able to receive and send the power of 1.2 gigawatts.
According to CEO Peter Wright, the project is part of a strategy for clean, reliable, and cost-effective power generation and storage for Australian businesses. The system will store energy from solar and wind power plants and supply it to the country’s power grid.
The fact is that the main problem of renewable energy is the irregularity of generation. The sun shines only during the day, and the wind can blow at any time. Meanwhile, the consumer must receive electricity at any time at the first flick of the switch.
This means that the energy generated by wind turbines and solar panels needs to be stored somewhere while the generators are working, and then this supply should be spent when they are idle. The colossal network of accumulators will be such a warehouse of electricity.
However, such a reserve will also be useful for traditional power systems in case of unexpected surges in electricity demand.
Such systems have already proven their worth. For example, a 150-megawatt battery, launched in 2017 in Australia, has generated huge profits for Tesla. The largest operating network of this kind belongs to LS Power and is located in the United States. Its capacity reaches 250 megawatts.
CEP Energy’s new brainchild sets a record of 1.2 gigawatts. It is assumed that the operation of the system will begin as early as 2023.
Overall, such storage systems serve not only to accumulate surplus electricity obtained from renewable sources, the sun or wind. They are great for balancing unexpected peak loads and are also beneficial for providers and consumers.
By the way, the new project is planned to use conventional lithium-ion batteries, like those that power smartphones and laptops. This energy storage technology is the best on the market today. No wonder the 2019 Nobel Prize in Chemistry was awarded for its development. Of course, the latest technology news says scientists are working on more advanced devices, but these developments have not yet left the walls of laboratories.
Speaking about another trend in energy storage, it is worth noting the fact that renewable energy sources are on the path of constant growth. The energy turnaround could advance even faster if the development of new energy storage technologies kept pace with the production of renewable energy. In Germany, for this purpose, a joint Research Platform on Energy Storage at the Fraunhofer Society and Battery LabFactory Braunschweig (BLB) of the Braunschweig University of Technology is being built. There, scientists want to improve mobile and stationary energy storage technologies.
Thus, electric vehicles will become flexible energy storage devices. Meanwhile, one startup from Wildpoldsried in southern Germany is making a splash. Sonnen uses a charging system to connect electric vehicles to a virtual high-capacity storage device. The users of the Sonnen-Charger energy storage system form a community for the sharing of solar electricity, which individual members generate with their photovoltaic power plants. A cutting-edge approach is that the charging system also connects electric vehicles to the grid and intelligently manages the charging process.
If there is not enough solar energy to charge the car, then excess electricity from other members of the community is used. Thus, all vehicles become part of a high-power virtual battery. They help take electricity from renewable energy sources, stabilize the grid and save money: Members of the electricity sharing community can sign an unlimited tariff plan and get up to 8,000 kilowatt-hours (kWh) per year for free.
