Renewable Energy And The Biogas Generator - Essential Hardware And Technology Moving Forward

When it comes to renewable energy and the future of green biofuels, the biogas generator is perhaps the most exciting and energy efficient technology that you've probably never heard of. What's even more exciting is that even though the generator itself isn't very expensive to make, larger scale models are becoming increasingly more affordable, making biogas one of the most cost-effective sources of alternative fuel. Here's everything that you need to know about biogas generators moving forward into a future economy that will center around renewable energy sources.

To start off with, a biogas generator is simply a chemical processing system—essentially a reactor—that breaks down biological sources through an organic process. The biosources are processed into methane and hydrogen gasses which can then be combined with oxygen to create a biofuel source of renewable energy.

Biogas Generators Technology and Creation Sets

In order to generate the biofuel, waste matter is used as biological sources of energy. This includes:

  • Manure
  • Municipal waste
  • Plants waste
  • Crop field waste
  • Residential lawn clippings
  • Park trimmings and leaves

Different Types of Biogas Generators

There are two types of biogas systems, homemade and industrial. Homemade biogas generators are simple to make, taking only about an hour with instructions that you can find online. In fact, it's so simple that they're often made for high school science projects. Typically speaking, a sealed container is filled with organic waste and then infused with anaerobic bacteria. The bacteria goes to work on the organic source material, breaking it down. Because the oxygen is quickly dissipated by the sealed container, the resulting gaseous result is a mixture of approximately 60% methane and 40% carbon dioxide. These gases are siphoned off into another container for processing into fuel sources, allowing you to make biogas from a portable generator.

Industrial biogas generators essentially work in the same manner, only on larger levels with with more sophisticated tools and technology. The chamber into which the waste is fed plants and other outdoor materials is more advanced, plus the reactor chamber uses digestive slurry that is more effective. All biogas is piped out from the top of the chamber while treated sewage—now called effluent—is discarded from the side. The process is more streamlined and the output of natural gas and biofuel is greater.

Parts of a Biogas Generator

Here are the seven major components of a biogas generator:

  1. Foundation: For larger plants and generators, the foundation is typically underground and made of cement concrete and brick ballast. For portable generators, it is just a solid base. This ensures that the digester is stable and can sustain large loads of slurry as they are poured in. It should also be waterproof in order to prevent water leakage..
  2. Digester: All of the chemical processes take place inside the digester, or fermentation tank The organic sources are turned into biogas here. The digester sits on the foundation and can be made of bricks, sand, cement or other containers for smaller units. There are typically two openings half-way up the cylinder, one for inserting organic sources and one for its removal.
  3. Dome: This is the top of the digester where biogasses collect. The height of the dome dictates how much pressure the gases exert on the slurry below.
  4. Inlet Chamber: This is the hole or feed tube in the digester into which organic source is placed for processing.
  5. Outlet chamber: This is where the effluent is removed, either manually or by machine.
  6. Mixer: Here, the organic source is mixed with water at a 1:1 ratio to create the slurry. It is then deposited through the inlet chamber.
  7. Gas Outlet Pipe and Valve: Located at the top of the dome, this is where the biogas is collected for use. The flow is regulated by the valve.

Who is Using Natural Gas from a Biogas Generator?

The main component in the natural gas that comes from biogas generators is methane. Methane is used to heat homes, cook, produce hot water and many other vital necessities. Because of this, large-scale applications of biofuel technology have made it one of the most energy efficient sources of renewable energy. Sewage plants in large companies like Britain and Germany turn the countries' municipal waste into biogas that is used to fuel electric power plants.

For smaller, portable generators, biogas fuel allows homes to process outdoor and indoor waste from the yard and kitchen. These biogas generators are popular in countries like Nepal, India and China, where homeowners have reported being able to meet between one-quarter to one-half of their cooking energy demands.

Biogas Generators Create Economic Boom

The production of biogas is becoming a viable renewable energy source all over the world. There are hundreds of companies dedicated to bringing consumers energy from organic waste, creating solutions to our energy problem that are both pragmatic and practical. By 2030, it is estimated that biogas production will be a $50 billion industry worldwide.

Progressive countries that are looking for solutions to waste management issues that arise from overcrowding have already found biogas production to be a viable solution to many problems. For example, India reports that biogas production accounts for 57% of the entire population's energy needs. Because of the large amount of cattle in the country—over 300 million—and extensive agriculture industry, India will never run out of organic waste. Not only does India's biofuel production create fertilizer for crops with the effluent, but it also reduces deforestation since the country's other main source of fuel is wood. With biogas generators in place, this also means India will never run out of energy—it is truly an essential industry and one that the whole world should sit up and take notice of right away.

For countries like the US, adopting biogas generators as a main source of renewable energy could reduce dependence on foreign oil. Families can also lessen their footprint, finding new ways to lead sustainable lives that lower the cost of living. Plus, the byproduct of the portable generators can be used to fertilize gardens for growing food. The food waste from the kitchen can be turned into biogas to power the cooking, which grows the garden, and so on, and so forth.
