Compressed air energy storage: Compressed air technology pressurizes atmospheric air, converting it into stored potential energy. When electricity is needed, the compressed air is released to flow through an expander (turbine-generator) to produce energy.

Thermal Energy storage: Is heating or cooling a medium (element) to use the energy when needed later. This could mean using a water tank for heat storage, where the water is heated at times when there is a lot of energy, and the energy is then stored in the water for use when energy is less available.

Concentrated Solar power: These systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver. Electricity is generated when the concentrated light is converted to heat (solar thermal energy), which drives a heat engine connected to an electrical power generator

Hydrogen storage: Hydrogen energy storage is another form of chemical energy, in which a electrical power is converted into Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks. Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen.

Hydrogen production: Hydrogen storage is can be reversed by using cooling or heating systems.

storing heat in reversable reactions: temperature change is reversible, but changes to other properties might be irreversible. Heating, in particular, often causes chemical changes in which atoms alter their bonding to form new substances.

what is a reversable reaction: A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously.

Impact of mining for battery materials: Whether lithium extraction involves salt flat brines or ore pit mining, land needs to be cleared to make way for these operations. Vegetation and trees must be destroyed and soil and earth removed

What are some more sustainable sourcing methods for obtaining raw materials for batteries?

What are some eco-friendly materials for batteries: Scientists developed ionic liquids for eco-friendly electrolytes in batteries. Bio-based electrolytes are prepared from renewable materials, such as plant oils and sugars. These electrolytes are non-toxic and have a low environmental impact.

What contributes to carbon emissions for different storage technologies: Carbon emissions are influenced by a multitude of factors like materials used, Manufacturing processes, Transportation of materials, End-of-life disposal or recycling practices.

How can we make creating batteries more environmentally friendly and sustainable?

how can we make Compressed Air Energy Storage more energy efficient?

land requirements for energy storage facilities: Battery storage farms typically require relatively small land footprints, while larger battery farms may require cleared land for installation. However large energy storage facilities like Pumped hydro storage projects, require significant land areas, especially for the construction of upper and lower reservoirs.

Ecological considerations for siting energy storage projects: When deciding where to place an energy storage facility, we have to Identify suitable sites that have minimal ecological value, considering proximity to sensitive areas such as protected lands. It’s also important to implement measures to mitigate habitat disturbance, by incorporating green infrastructure, such as vegetative buffers and wildlife-friendly designs.

How is the government helping in miniating the environmental impact on land for energy storage facilities?

Recycling batteries: Spent batteries are collected from various places including households and industries, and then sorted based on their chemistry and size for appropriate recycling processes. Batteries are disassembled to separate components, then the recovered materials undergo processes like smelting to extract metals such as lithium. These purified metals and materials are used to manufacture new batteries.

Environmental risks of improper disposal: Improper disposal of batteries can lead to soil, water, and air pollution due to the release of toxic substances such as heavy metals. Leaching of pollutants into groundwater or surface water can contaminate ecosystems and pose risks to human health. Discarded batteries, especially lithium-ion batteries, can pose fire hazards if not handled properly during disposal. Thermal runaway and combustion of batteries release hazardous fumes.

How can we make disposing of batteries easier for people?

What are the laws around disposal of batteries and energy storing components?

What is the government doing to help promote clean energy?

What are some public outreach campaigns for promoting clean energy storage in Australia?

Public perception is based on information, therefore we need to provide information on how energy storage contributes to grid stability, reduces energy costs, and supports clean energy goals.

What is the government doing to ease public concerns surrounding energy storage technologies?

Public concerns: There are many concerns surrounding energy storage technologies. Common concerns include, 1. Safety, like fire risk, chemical exposure, and electromagnetic fields. 2. Environmental, like resource depletion, pollution, land use, and habitat disruption. 3. Health and well-being, like noise pollution, and air pollution health implications. 4. Security and reliability, like grid stability and cybersecurity of smart grid technology. 5. Cost, like cost-effectiveness, affordability, and financial viability.
