Heating - World Liquid Gas (WLGA)

Heating and cooling systems account for a substantial portion of global energy consumption and carbon emissions. These systems are essential for maintaining livable indoor temperatures, preserving food and medicine and facilitating industrial processes. However, the traditional methods of heating and cooling, often reliant on polluting fuels, contribute significantly to greenhouse gas emissions. To achieve meaningful progress in mitigating climate change, addressing emissions related to heating and cooling is imperative.

1/2

Heating and cooling constitutes around half of energy consumption in the EU.

10%

Cooling represents 10% of total energy consumption.

25%

Heating, ventilation, air conditioning and refrigeration equipment uses around 25% of all electricity produced in Australia.

1/2

Available systems and fuel types

There are several technologies aimed at reducing emissions from the shipping industry.

	Energy source	Opportunities	Challenges
Furnaces Furnaces heat air, which is then distributed through ducts to various rooms in the house.	Electricity Natural gas Liquid Gas Heating oil Coal	Proven technology New generation offer high level of efficiency Can seamlessly switch to renewable fuels	Emissions is fossil fuels are used Particulate emissions if heating oil or coal are used
Boiler Boilers heat water, which is then circulated through radiators or underfloor heating systems or used to heat water.	Electricity Natural gas Liquid Gas Heating oil Coal	Proven technology New generation offer high level of efficiency Can seamlessly switch to renewable fuels	Emissions is fossil fuels are used Particulate emissions if heating oil or coal are used
Heat pumps Heat pumps extract heat from the air, ground, or water sources and transfer it indoors.	Electricity	More energy-efficient than fuel-based or electric resistance systems No emissions if powered by renewable electricity Depending on the cost of electricity, thye can generate savings Can provide cooling as well as heating	Limited pool of installers Only as clean as the electricity used Requires reliable green electricity supply
Solar thermal heaters Solar thermal heaters use solar collectors on the roof to produce hot water.	Solar	Only use sunlight and this produce no emissions Inexpensive and low tech Can be combined with boiler as a back up	Water volume is limited to the size of the tank
Stoves Stoves are the oldest form of heating and involve burning biomass	Coal Wood Wood pellets	If sustainable sourced wood is used, the carbon balance is neutral	Inefficient combustion High particulate matter emissions If coal is used the CO2 emissions are high
Air conditioning The process of absorbing heat from indoor air and releasing it outdoors results in the cooling of the indoor space.	Electricity	Can provide heating and cooling	Requires large amounts of electricity
Space heaters These are standalone units that generate heat and are often used to supplement central heating systems.	Electricity Liquid Gas	Inexpensive	Low efficiency Emissions
Electric radiators	Electricity	No emission is green electricity is used Efficiency	Expensive if electricity costs are high Not suitable for all areas
District heating Heat networks, available in some areas, are centralised systems distributing heat through underground pipes	Coal Electricity Natural gas Recovered heat	Energy efficiency and possible use of recovered heat Reduces space use and maintenance Possible emissions saving	Mostly fossil fuel-powered Losses in distribution Initial cost

The role of Liquid Gas

Liquid Gas is a valuable solution for heating, particularly in rural areas. Remote and off-grid communities often lack access to centralised energy sources, making Liquid Gas an efficient alternative. Liquid Gas is a clean-burning fuel, emitting fewer pollutants and CO2 emissions compared to coal or heating oil. Its portability and ease of use make it well-suited for regions where infrastructure challenges limit the reach of other energy sources.

Why Liquid Gas?

Locally stored energy

Liquid Gas is stored in a tank on the property, ensuring energy is available even in the most adverse weather conditions.

Soil protection

Liquid Gas does not leak and therefore does not pollute the soil.

Efficient

A heating system using renewable gas is very efficient.

Low emissions

Liquid Gas emits less CO_{2,/sub> and pollutants compared to coal or heating oil.}

Hybrid systems

Liquid Gas finance can be combined with heat pumps to complement or act as back-up.

A partner for renewable energy

Liquid Gas systems can complement solar water heaters, only being used when called upon.

Integration with micro-CHP system

With a micro-CHP unit, you can cover up to 100% of your heating needs and up to 80% of your electricity needs, making you independent from third-party suppliers.

Switch to renewable Liquid Gas

Heating systems can seamlessly switch to a range of renewable Liquid Gas, thereby further reducing emissions.

48%

About 48% of LPG use in the EU goes towards residential heating

11.8 million households, particularly in rural areas, rely on propane as a major fuel source. This means about 5% of all U.S. households use LPG as their primary space-heating fuel. At least 14% of homes in Vermont, New Hampshire, South Dakota, North Dakota, and Montana use LPG as their primary heating fuel.

Liquid Gas and
the energy transition

Space heating is a major source of emissions. Energy-efficiency measures can substantially reduce emissions, and heat pumps running on renewable power will play an important role. However, the climate clock is ticking and we will need a broad range of solutions to reduce emissions. Switching from coal or heating oil to Liquid Gas will help reduce emissions, and these emissions will be further when switching to renewable Liquid Gas.
