Different ways to decarbonize the UK’s heating requirements 

For the first time since 2011, global emissions grew 2% in the last year, outstripping the rapid rollout of green energy. The increased emissions level was equivalent to driving 400m extra combustion engine cars on roads.

There is a link between the level of carbon and the vicious weather patterns mostly triggered by stronger growth in energy use and emissions as households and businesses seek to reduce the impact.

According to Times, the UK report on changing weather patterns, London will be hot like Barcelona in 30 years, and Leeds will be like Melbourne.

The northern hemisphere will resemble the southern, which can lead to extreme droughts in London, where they may have to import drinking water.

There was an unusual number of heating days in the first month of the year, particularly across the continents, where the number of extremely hot and cold days was usually higher in China, the US and Russia –where fossil fuel use continues to increase.

Decarbonizing heating in the UK

To reach the net zero carbon targets, there is an immediate need to electrify heating and transportation requirements using heat pumps and electric cars.

The assessment made by the UK National Grid states the country will be able to achieve net zero targets only if immediate actions were taken to overhaul the heating, transportation and electricity system.

The UK heating solutions should be changed radically and massively to improve efficiency and meet the domestic demand, which can be completely delivered through electric or hydrogen technologies.

Heat is one of the toughest aspects of implementing zero-emission plans. Corporate strategies have a greater role in markets like North America and Northern Europe.

The gas networks are keen to use hydrogen as a replacement for natural gas; some believe using hydrogen or heat can be a waste of resources.

Different hybrid systems can be used in different regions. Like in Amsterdam, heat comes from gas CHP and waste, saving 50 per cent of CO2.

Geothermal can be used at many places with a higher temperature that can boost the large industrial heat pumps to 65-70 degrees.

Holland has a lot of water in the form of sewage water, which can be combined with these pumps to generate heat.

Over time the combination of heat with geothermal sources, water sources and others can generate electricity.

HPs have been widely adopted in the UK, and focusing on hybrid pumps can improve efficiency based on gas and electricity and provide cheaper alternatives to generate power.

The greater use of EVs and HHPs can help in reducing electricity costs. Rapidly using the combination of EVs ad HHPs can cut the full electricity price by 7 per cent.

The UK adopted EVs more vigorously than HHPs and low investment in the HP sector was mainly due to the abundance of gas connections in the country. The role of HPs increased in the last few years like in Germany, the installation of the new home increased from 1 per cent.

From 2000 to 23 per cent in 2016, due to policy support and incentive programs, it was noticed that retrofitting old homes was difficult.
