Dual Fuel
Dual fuel refers to systems or engines that use two different types of fuel to operate. Here are some common applications:
Dual Fuel Engines: These engines can run on a combination of two fuels, typically diesel and natural gas. The diesel fuel acts as the ignition source, while the natural gas provides the bulk of the energy 1 2. This setup can improve fuel efficiency and reduce emissions.
Dual Fuel Heating Systems: These systems combine an electric heat pump with a gas furnace. The heat pump is used for heating and cooling during milder weather, while the gas furnace takes over during extremely cold conditions 3. This hybrid approach maximizes energy efficiency and comfort throughout the year.
Dual fuel systems offer flexibility, cost savings, and environmental benefits by optimizing the use of different fuel sources based on availability and efficiency 2.
Aberdeen(/ˌæbərˈdiːn/ⓘAB-ər-DEEN;locally[ˌeːbərˈdin]ⓘor[ˈeːbərdin]ⓘ;Scottish Gaelic:Obar Dheathain[ˈopəɾˈʝɛ.ɪɲ]) is a port city in North EastScotland, and is thethird most populousScottish city.

Aberdeen has a long, sandy coastline and features anoceanic climate, with cool summers and mild, rainy winters.[5]
Aberdeen receivedroyal burghstatus fromDavid I of Scotland(1124–1153),[6]which transformed the city economically. The traditional industries of fishing, paper-making, shipbuilding, and textiles have been overtaken by theoil industryand Aberdeen's seaport. Aberdeen Heliport is one of the busiest commercialheliportsin the world,[7]and the seaport is the largest in the north-east part of Scotland.[8]Auniversity town, the city is known for theUniversity of Aberdeen, founded in 1495 as the fifth oldest university in the English-speaking world and located inOld Aberdeen.
During the mid-18th to mid-20th centuries, Aberdeen's buildings incorporated locally quarried greygranite, which may sparkle like silver because of its highmicacontent.[9]Since the discovery ofNorth Sea oilin 1969, Aberdeen has been known as the offshore oil capital of Europe.[10]Based upon the discovery of prehistoric villages around the mouths of the riversDeeandDon, the area around Aberdeen is thought to have been settled for at least 6,000 years.[11]
