1. What is Natural Gas?

A natural product of trapped plant and animal matter. Natural gas forms when plant and animal matter are trapped beneath solid rock under tons of pressure for millions of years. Made up mostly of methane, natural gas is both odourless and tasteless in its original form.

2. If natural gas is a fossil fuel, why is it better to burn than other fossil fuels like oil and coal?

Lower carbon emission and more efficient feedstock. Burning natural gas does result in some nitrogen oxides as well as carbon dioxide, but in much lower quantities (nearly half!) compared to when coal or oil is burned. This is due to the fact that natural gas is less chemically complex than other fossil fuels.

3. What’s the Difference Between Natural Gas and Shale Gas?

Shale gas is a form of natural gas.
Shale gas is simply natural gas that is found in shale formations, or fine-grained sedimentary rocks deep within the earth’s surface. Obtaining shale gas used to be uneconomical, but with advancements in technology over the past decade, this has become a more popular and cost-effective resource.

4. What Is Liquefied Natural Gas (LNG)?

Natural gas converted to a liquid. LNG is simply natural gas that has been converted into a liquid. When cooled to -260°F, natural gas converts to a liquid form, shrinking its volume and making it easier to store and transport. The process involves removing the heavy hydrocarbons, which results in almost pure methane. The clear, odorless liquid that remains is non-corrosive and non-toxic.

5. Why does natural gas have an odour?

A non-toxic substance called Mercaptan for easy detection of gas leaks.
Mercaptan, a harmless, non-toxic substance that has a strong “rotten egg” smell is added as a safety precaution to natural gas (and propane) to make it easier to detect in case of a leak –Natural gas is itself colourless and odourless. If you should detect this odour in your home, immediately open windows, leave the house and call us from a neighbour’s telephone. We’ll send a Service Representative to investigate. We provide 24-hour emergency response to anyone who calls in and tells us they smell gas. We work very hard at maintaining exacting safety standards and we take pride in our safety record.

5. How can I be sure of an uninterrupted supply?

Relying on a utility company that has safe and diligent operating/maintenance protocols.
At GasHub we impose and follow stringent operating procedures and standards to ensure you have a reliable supply of natural gas. We purchase natural gas from a variety of suppliers and have access to a number of alternate pipelines to bring natural gas into our system. This gives us operational flexibility and lowers the risk of service disruption. In addition we have backup facilities to ensure continuous operation of important lines and equipment and we conduct periodic reviews of our emergency response system.

7. How is the price for natural gas established?

Market forces.
Natural gas like other commodities, is publicly traded and the market price varies in response to factors such as weather conditions, petroleum prices, natural gas production, and storage levels. Since there are so few alternatives for heating and electricity generation, the price may change dramatically if supply or demand varies quickly during periods of peak demand. GasHub adjusts the rates we charge our customers for natural gas every three months to reflect ongoing changes in the market price of natural gas and these costs are passed through to customers without any mark-up. All rate changes require Energy Market Authority’s approval.

8. When Is the Best Time to Purchase Natural Gas?

Locking in at a low price. If your business is in a state with a deregulated natural gas market, consider looking into supply pricing now. If you are under contract, you can still lock in today’s prices for the future.

9. Can we run out of natural gas?

Natural gas is a finite resource, but it will be present at current consumption rate for decades to come.
There is an abundant supply of natural gas — so much so that natural gas will continue to be the energy source of choice for Singapore for many decades to come. This conclusion is strongly supported by statistics put out by energy agencies around the world.

10. How much coal, natural gas, or petroleum is used to generate a kilowatthour of electricity?

It depends on the efficiency of the generator and the heat content of the fuel.
The amount of fuel used to generate electricity depends on the efficiency or heat rate of the generator (or power plant) and the heat content of the fuel. Power plant efficiencies (heat rates) vary by types of generators, power plant emission controls, and other factors. Fuel heat contents also vary.
Two formulas can be used to calculate the amount of fuel used to generate a kilowatthour (kWh) of electricity:
  • Amount of fuel used per kWh = Heat rate (in British Thermal Units (Btu) per kWh) divided by Fuel heat content (in Btu per physical unit)
  • Kilowatthour generated per unit of fuel used = Fuel heat content (in Btu per physical unit) divided by Heat rate (in Btu per kWh)
