Heat is one way in which energy can be stored, meeting a gap in the energy sector that must be filled to reach a renewable energy future. It has been noticed that salt has particularly good characteristics for heat storage, making it a great base for capturing and holding energy.
The system heats the salt to 565 °C. The salt is then fed into a hot storage tank where it can be kept for several days. When needed, the thermal energy is turned into electricity by means of a steam turbine.
Biomimicry (literally: imitation of the living ) aims to take inspiration from natural selection solutions adopted by nature and translate the principles to human engineering. The biomimicry approach aims to favor “choices” tested by nature which had millions of years to understand what works best and what doesn’t.
Mimicking plants and the natural environment is a method of sustainability that is only dreamt of. Scientists are working to capture the regenerative functions of plants and animals, similar to healing a wound or sealing a cut made when pruning a plant. This technology could be used in fibres to enable cuts to patch up minor holes and tears.
The first flying machine heavier than the air from the Wright brothers, in 1903, was inspired by flying pigeons.
Although controversial based on its potential to disrupt cities (an example being the Chernobyl nuclear reactor), technology is being developed to make the most of nuclear materials to produce clean energy at scale. Current technicians are only able to utilise uranium supplies to around 1% of their full potential, making nuclear a contender for widespread green energy.
Inside nuclear power plants, nuclear reactors and their equipment contain and control the chain reactions, most commonly fuelled by uranium-235, to produce heat through fission. The heat warms the reactor’s cooling agent, typically water, to produce steam. The steam is then channelled to spin turbines, activating an electric generator to create low-carbon electricity.
It is a process in which a relatively pure stream of carbondioxide from industrial sources is separated, treated and transported to and long-term storage location.
CO2 storage regulations require that storage operations be rigorously monitored for a number of reasons, including:

From the energy aspect, EVs offer a secure, comprehensive and balanced energy option that is efficient and environmentally friendly.
From an environmental aspect, EVs can provide emission-free urban transportation. Even taking into account the emissions from the power plants needed to fuel the vehicles, the use of EVs could still significantly reduce global air pollution.
From a transportation aspect, EVs ean provide intelligent transportation systems that will improve road utilization and traffic safety.
The key technology in an electric vehicle includes automotive technology, motor drive technology, power electronic tcchnology, mirco electronic technology, control technology, energy storage and battery technology,etc. Although energy storage and battery technology is the crucial technology, but power electronic motor drive and control technology is the enabling technology, and the integration of all related technology is the key of success.

Artificial photosynthesis is referred as “a mimic of photosynthesis process” that harvest natural sunlight and in turn convert the CO2into fuels like hydrogen and carbon based. The hydrogen is produced from water splitting while carbon-based fuels like methanol, methane, or CO are usually produced from the reduction of CO2 in the presence of water. Since hydrogen production will be discussed as separate section, this section will focus on the reduction of CO2 to solar fuels and their application in other industries.
Artificial photosynthesis is a process that mimics a very famous biochemical reaction: natural photosynthesis. The artificial photosynthesis system includes an enzyme bed reactor to fix CO2 in the air (or any other source needing CO2 to be removed). This reactor is fueled by hydrogen energy and bioelectric transducers. The key components of an overall artificial photosynthesis system are:
