Answer :
Batteries are the most promising technology for fueling automotive vehicles in the future due to their efficiency, environmental benefits, and advancements in technology.
Batteries, particularly lithium-ion and solid-state batteries, offer high energy efficiency and zero emissions at the point of use. These characteristics make them a sustainable option for reducing greenhouse gas emissions and combating climate change. Additionally, the rapid advancements in battery technology, such as increased energy density and faster charging times, are making electric vehicles (EVs) more practical and appealing to consumers.
Environmental Benefits:
- Zero emissions at the point of use, contributing to cleaner air.
- Potential for renewable energy integration, reducing overall carbon footprint.
Technological Advancements:
- Improvements in battery capacity and lifespan.
- Decreasing costs and expanding charging infrastructure.
In contrast, synthetic fuels produced with solar energy, while a potential alternative, currently face challenges such as lower overall efficiency and higher production costs. Batteries' direct use of electricity for powering vehicles is more efficient than converting electricity into synthetic fuels, making them a more viable and immediate solution for the future of automotive transportation.
Green hydrogen is the fuel of the future, but it has a concerning blind spot, according to scientists. Green hydrogen, which is produced only from renewable energy, is emerging as a possible replacement for dirty fossil fuels.
Why batteries or synthetic fuels produced with solar energy?
The polymer electrolyte membrane (PEM) fuel cell is the most popular kind of fuel cell used in automotive applications. An electrolyte membrane is positioned between a positive electrode (cathode) and a negative electrode in a PEM fuel cell (anode).
The cathode receives oxygen from the air, whereas the anode receives hydrogen. An electrochemical process takes place in the fuel cell catalyst, causing the hydrogen molecules to split into protons and electrons. The membrane then allows protons to go to the cathode.
The electrons must pass through an external circuit in order toOn the cathode side, where the protons, electrons, and oxygen molecules combine to form water, the electrons perform work (supplying electricity to the electric car) before recombining with the protons. For additional information on the procedure, see the Fuel Cell Electric Vehicle (FCEV) infographic.
