Bio-gas Could Be More Accessible Than You Think
Green energy sources will be used to produce electricity and to run computers, and a source of reliable fuel for transportation and for heating. The new concept would be based on a “green” fuel source: bio-gas.
This is the first time the concept of a green fuel has ever been proposed for commercial production, and the first time it has ever even been considered as a possible alternative. But it is a very close call. The process of converting biomass into bio-gas is called biomass, and it is the fastest and cheapest way to produce electricity. It’s also the only way to get hydrogen out of a fuel cell vehicle.
A major obstacle to the widespread adoption of biomass for fuel and electricity is that it’s very difficult to find suitable feedstock, which can be used to produce bio-gas in a fuel cell vehicle. Bio-gas is made from a combination of biomass and a carbon source.
The process is relatively simple and easy to duplicate in home composting, but it’s not simple to handle, and it’s not simple to transport.
There are a lot of misconceptions about the process. Here’s an excerpt from an article from the National Renewable Energy Laboratory (NREL) describing how it works.
The process is simple and can be duplicated in your home, where you don’t need to be a gas engineer or a petroleum engineer. It’s just an added step, like an extra step in a car engine. You need to use the same amount of biomass that you use for your personal energy use, and it’s easy to make a carbon-based form of hydrogen out of the biomass in the process.
The process starts by heating the biomass to above 55 degrees Celsius. The heat causes the chemical bonds between the cellulose and hemicellulose to rearrange, so that hemicellulose becomes a tiny, fragile protein. This protein produces hydrogen, which can then be stored.
The process is really just a two-step chemical process, so you need to heat the biomass in the same way you would in your kitchen. You don’t need to use electricity to produce hydrogen from the biomass, it’s all free.
The carbon produced during the process is used to make fertilizer, and the hydrogen is then used to make gasoline, water, and nitrogen, all of which are non-renewable resources.
“The process is very simple and not complicated. It’s very similar to making fertilizer,” says NREL’s Brian Enid.
Bio-gas can be used for fuel cells, which has always been seen as an energy storage device. But instead of using electricity, it uses carbon dioxide and water instead. “It’s the process of converting biomass to carbon dioxide and water. It’s something you can do in your garden,” says Enid.
