2. Micro combined heat and power - Wikipedia

   en.wikipedia.org/wiki/Micro_combined_heat_and_power

   The future of combined heat and power, particularly for homes and small businesses, will continue to be affected by the price of fuel, including natural gas. As fuel prices continue to climb, this will make the economics more favorable for energy conservation measures, and more efficient energy use , including CHP and micro-CHP.

3. Cogeneration - Wikipedia

   en.wikipedia.org/wiki/Cogeneration

   This hence still emits CO 2 (see reaction) but (temporarily) running on this can be a good solution until the point where the hydrogen is starting to be distributed through the (natural gas) piping system. Another MicroCHP example is a natural gas or propane fueled Electricity Producing Condensing Furnace.

4. Liquefied petroleum gas - Wikipedia

   en.wikipedia.org/wiki/Liquefied_petroleum_gas

   LPG is composed mainly of propane and butane, while natural gas is composed of the lighter methane and ethane. LPG, vaporised and at atmospheric pressure, has a higher calorific value (46 MJ/m 3 equivalent to 12.8 kWh/m 3) than natural gas (methane) (38 MJ/m 3 equivalent to 10.6 kWh/m 3), which means that LPG cannot simply be substituted for ...

5. Gas heater - Wikipedia

   en.wikipedia.org/wiki/Gas_heater

   A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented .

6. Gasoline gallon equivalent - Wikipedia

   en.wikipedia.org/wiki/Gasoline_gallon_equivalent

   One GGE of natural gas is 126.67 cubic feet (3.587 m 3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values : 900 BTU/cu ft (9.3 kWh/m 3 ) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline).

7. Propane - Wikipedia

   en.wikipedia.org/wiki/Propane

   Propane is much more commonly used to fuel vehicles than is natural gas, because that equipment costs less. Propane requires just 1,220 kilopascals (177 psi) of pressure to keep it liquid at 37.8 °C (100 °F).
