Global warming is – as the name already suggests – a global concern. It causes problems such as sea level rise, more frequent and more severe strms, and longer droughts. Thus, it global warming concerns all of us. To best fight global warming, adopting green energy in your life is the best viable solution.
Green energy is getting more attention today. It helps to reduce our carbon footprint and thus curbing the global warming. Increasing carbon footprint is the main cause for rising temperatures. Moreover, investing in green energy is also a business case generating steady revenue stream without marginal costs. Hence, many governments promote the use of green energy by providing subsidies and teaching people its benefits in their life.
There are many ways green energy is produced, for example, solar energy, wind energy, the energy produced through bio-waste. Fuel cells are a major breakthrough in this regard. They have impacted the production green energy in many ways. They are also convenient to use. As their fuel (hydrogen, methane …) is produced by using electrical energy, they can use a wide range of green sources to produce energy.
What Are Fuel Cells?
A fuel cells is a device that converts chemical energy into electrical energy. The process combines hydrogen and oxygen to produce water& electricity as main products. Fuel cells are somewhat similar batteries. The main difference is that a fuel is supplied without a charge-discharge cycle. Like batteries, fuel cells are portable and can be used with a variety of fuels like ethanol, methanol, methane, and more.
There are different types of fuel cells. But the most popular ones are hydrogen fuel cells that provide a wide range with only some of advantages as follows:
- The cells are more efficient than conventional methods used to produce energy.
- They are quiet – unlike, for example combustion engines or turbines
- Fuel cells eliminate pollution by using hydrogen instead of burning of fossil fuels.
- Fuel cells have a longer lifespan than batteries because fresh fuel is supplied constantly
- They use chemical fuels that can be recycled or produced using renewable energy which makes them environmentally friendly.
- Hydrogen fuel cells are grid-independent and can be used anywhere.
How Do Fuel Cells Work?
A fuel cell produces power by transforming chemical energy into electrical energy in reduction-oxidation processes, much like batteries do. However, unlike batteries, they produce electricity from external supplies of fuel to the anode and oxidants to the cathode. Fuel cells are capable of producing energy as long as the fuel required to produce energy is supplied. Main components of fuel cells are electrolytes that allow for ion exchange. They aid the electro chemical reaction.
Hydrogen, ethanol, methanol, and methane are used as a source of energy. Methane, which is extracted from the subsurface, can be transformed into hydrogen rich stream. With an abundance of the hydrogen in nature, fuel cells seem to be the most viable technology that helps to produce green energy at large scale and at the most affordable cost.
Fuel cells are all set to become the most reliable source of green energy in the near future. They are fuel efficient, so businesses can make the best use of them. At Frontis Energy, we offer a unique selection that helps you build and improve your own fuel cells – be it for research and development or for production.
