Gasification in your everyday!

I use the word “gasification” a lot when discussing possible directions for the future of energy, but not a whole lot of people understand what the process actually is. Well fear not! I’m here to make biomass gasification a little easier to understand by explaining how it affects your everyday life.

First, what the heck is gasification? Biomass gasification is the process by which biomass fuels like wood, coal, feedstock and agricultural residues are converted into a combustible mixture known as a producer gas (CO+H2+CH4) or synthetic gas (syngas). The process relies on heat, pressure and partial combustion. The oxidizer can be air, in which case the producer gas will contain nitrogen (N2), steam, or oxygen (O2).

Sound complicated? That’s because it is! Just listen to what gasification technology can be used for:
- Central heating, community heating, or process heating for manufacturing
- Electricity generating systems
- Internal combustion engines

Now, gasification isn’t exactly a new technology. It was first developed back in the 1800s as a means of lighting villages and towns. Miniaturized gasifiers were even used to power vehicles during World War II, when fuel shortages were common. But as technology has advanced, so too has our understanding of gasification’s potential.

It all boils down to the science, really. If gasification occurs at a moderately low temperature (between 700ºC and 1000ºC), the product gas will possess a high concentration of hydrocarbons. This means that low temperature gasification can be used directly to generate electricity via a steam turbine or, with suitable gas clean up, an internal combustion engine.

Conversely, high temperature gasification (between 1200ºC and 1600ºC) results in few hydrocarbons and a higher ration of CO and H2. This is known as a syngas since it can be used to synthesize chain hydrocarbons. If the ratio of CO to H2 is 1:2, synthesis can successfully convert syngas into high quality diesel biofuel – a fuel compatible with most conventional diesel engines.

Come on - you didn't think the fuel you pumped at the gas station just came out of the ground like that, did you?

Ultimately, gasification has the potential to lower commuting costs for motorists. It can power cities. It can shape foreign relations with countries in control of the supply of crude oil. It can bring energy independence to impoverished countries. It can bring an end to dangerous fracking operations. It can change the world!

By now, you may or may not have a better understanding of gasification (hopefully you do). But even if you’re still having trouble wrapping your head around the idea of “hydrocarbons,” don’t worry. Gasification is a complex process mastered only by those who’ve dedicated years to studying the science behind it.

Tips for Your Gas Tank

Although governments have done their best to keep the price of gasoline down, it teeters at an all-time high. Hybrid and electric cars are more prominent on the road, yet still haven’t matched the price-point of their gasoline counterparts. So besides trading their vehicles in, what can drivers do to cut down on their trips to the pump?

1.  Never top off your tank! People like to round to the nearest whole number because it looks cleaner, but in reality, topping off is a huge waste of energy. Once you hear the nozzle click, that’s your key to stop! The additional gas you pump will only go to waste.

2.  Make sure your gas cap is screwed on tight. Every year, more than 140 million gallons of gasoline are wasted due to evaporation. After refueling, make sure your gas cap is screwed on tight to prevent fuel from leaking and/or evaporating.

3.  If you own a garage, use it for your car! Don’t use it for storage. Don’t become a hoarder. Throw out your old junk and make room. Keeping your car parked in a covered area will keep it warm during the winter and cool during the summer, cutting down on how much you have to use the heater and AC.

4.  Don’t own a garage? That’s OK! Just make sure you keep your car parked in a shady area. Even consider buying a windshield shade to block out the sun. The summer heat can really put a lot of stress on your car’s engine. Not to mention make your interior and unbearable oven. Really – who likes getting into a car that’s been sitting out in the sun all day?

5.  Don’t wait until you see the “Check Engine” light before checking your engine. Make sure it has enough oil. Antifreeze. Regular car maintenance will save you hundreds of dollars at the pump. Pay a little now. Save a lot later.

6.  While you’re under the hood, take a peek at your engine’s air filters. Over time, they get clogged with dirt and grime, which forces your engine to consume more fuel. By replacing your air filters every 3,000 miles, you can reduce your fuel consumption by 10%, saving up to 15 cents a gallon.

7.  When’s the last time you checked your tires? I bet you didn't know that under-inflated tires force your engine to exert more energy, thus guzzling more gas. Take the time to stroll around your vehicle. Kick the tires. If one feels a little flat (you can tell by the awkward thump), go and and get some air!

You’ll be surprised at how little you have to stop at the pump next month. Follow NRGLab at nrglab.asia for more information on what we’re doing to improve gasification processes and fuel-efficiency. Join us, and support a better future.
