Mechanics can also assemble and test EV parts, diagnose failures, and troubleshoot potential solutions. This can include working directly with customers in garages to explain vehicle issues and recommend future repairs to improve performance.

With the growing demand for EVs, the role of mechanics in this field is becoming increasingly important. Mechanics with EV expertise will be in high demand to service and repair these vehicles as more people adopt them.

Mechanics can improve energy storage solutions

Mechanics play a crucial role in improving energy storage solutions, which is essential for reducing pollution and our environmental impact. Here are some ways in which mechanics can contribute to this important field:

Flywheel Energy Storage Systems (FESS)

Flywheel energy storage systems, such as the Faraji et al. (2017) model, store energy in the form of kinetic energy through the rotation of a large mass with high inertia. This system is ideal for short-duration, fast-response backup power and can provide high power in very short periods. The challenge in developing FESS lies in their limited storage density, but they offer high efficiency, a long lifetime, and low maintenance requirements.

Pumped Hydropower Storage (PHES)

Pumped hydropower storage is a well-established technology that uses pumps to move water between reservoirs at different elevations. During periods of low demand, surplus electricity is used to pump water to a higher reservoir, storing potential energy. When there is a high demand for power, the water is released back to the lower reservoir, driving turbines to generate electricity. PHES has the advantage of being a mature technology with high efficiency, but it requires specific geographical conditions and has high capital costs.

Compressed Air Energy Storage (CAES)

Compressed air energy storage is another promising mechanical energy storage technology. CAES uses excess electricity to compress air and store it in underground caverns or tanks. When power is needed, the compressed air is released, heated, and expanded through turbines to generate electricity. CAES offers the potential for large-scale energy storage and has high cost-effectiveness. However, it also faces challenges related to geographical limitations and the need for specialized underground caverns.

Pumped Heat Energy Storage (PHES)

Pumped heat energy storage is a newer form of mechanical energy storage that converts electric energy into thermal energy stored in tanks. This system can store energy for extended periods, from hours to several weeks, and then convert it back into electrical energy as needed. PHES has the advantage of being able to provide a significant amount of electricity for extended periods.

Hydrogen Energy Research

Mechanics are also involved in hydrogen energy research, exploring the potential of hydrogen fuel cell electric vehicles (FCEVs) as a clean energy alternative. While FCEVs only emit water, the hydrogen they rely on is currently derived mostly from fossil fuels. Mechanics are working to improve the efficiency and affordability of FCEVs and to address the environmental impact of hydrogen production.

Mechanics have a crucial role in developing and optimizing these energy storage solutions, contributing to a more sustainable and less polluting future.

Mechanics can improve waste management

Mechanics and mechanical engineers play a vital role in improving waste management and reducing pollution. They are responsible for maintaining and repairing the machinery and vehicles used in waste management operations, such as trucks, haul trucks, water trucks, and heavy equipment. This involves ensuring vehicles are properly maintained, serviced, and fuelled efficiently.

Mechanical engineers are also at the forefront of designing and creating new technologies for waste management systems. They develop advanced recycling systems and high-tech sorting systems that use robots and smart software to accurately sort garbage, increasing recycling rates. These engineers design machines that can handle a variety of waste streams and adapt to changing types of garbage over time.

Additionally, they play a crucial role in converting waste into energy through processes like pyrolysis and gasification. By burning waste without oxygen, they can turn trash into usable gas, reducing the amount of waste sent to landfills.

Mechanical engineers also contribute to sustainable material development, creating bio-based polymers and composites that are environmentally friendly while maintaining performance comparable to traditional plastics. They analyse the environmental impact of materials throughout their life cycle, from production to disposal, to ensure a more sustainable future.

Furthermore, mechanics and mechanical engineers can provide training and education to less experienced colleagues in the field of waste management.
