Advantages and disadvantages of burning hydrogen for low carbon heating

There is a lot of talk about the merits ofburning hydrogen for heating. This has some some merits for low carbon heating, but there are some significant costs, safety issues and serious health issues.

Getting serious about Net Zero

We need to begetting serious about net zero and limiting our carbon emissions. The route to lower carbon emissions is to stop burning fuels for heating and transport: there are alternatives.

Fifth Generation District Heating Networks

New fifth generation district heating networks avoid heat losses to the ground by circulating water to buildings at near ground temperture – this allows heat pumps in each building to extract heat, if they need heating, or reject heat, if they need cooling. Buildings which need heat benefit from those which reject heat to the heat sharing network and vice versa.

Advantages of District Heating

There is an alternative form of district heating which neatly resolves all the limitations of CHP based district heat networks: district heating based on heat pumps.

Decarbonising Cooling

Up to 10% of UK electricity is used to provide air conditioning and cooling. The mechanism of using roof mounted chillers to waste heat to the atmosphere is very inefficient. There is a much better route to decarbonise cooling.

Decarbonising Heating

The grid is decarbonising each year. The electrification of heat is advancing. Do you know the best route to decarbonising heating?

Decarbonising the Grid

In order to meet international obligations the government is arranging for the decarbonisation of electricity generation for the national grid. This decarbonising of the grid is encouraging the electrification of heat.

Interseasonal Heat Storage

The key to balancing supply and demand on the grid is to be found in electricity storage and Interseasonal Heat Storage.

Internet of Things

Connecting heat pumps to the National Grid via the Internet of Things enables Demand Side Response, load balancing and saving costs: Internet of Things – heat pump controls.

Integrating Renewable Technologies to recycle heat from summer to winter

Renewable energy technologies can be combined in order to balance the merits of solar thermal collectors with ground source energy using the critical link of Seasonal Thermal Storage. The whole is greater than the sum of the parts. See Integrating Renewable Technologies to recycle heat and achieve energy efficiency in buildings.

Energy Trilemma

Policy makers are concerned about the Energy Trilemma: they need to resolve the needs for

  • high security of supply
  • low carbon emissions
  • and low cost of energy.
There is a solution to the Energy Trilemma.

Air Quality

All but two of London’s boroughs are exceeding EU limits for Nitrogen Dioxide, a toxic gas linked to respiratory problems. Air Quality is becoming an increasing concern in urban planning. There is a solution for reducing air pollution.

Electrification of Heat

In order to reduce carbon emissions from heating we need to find alternatives to combustion. This implies the Electrification of Heat which in turn means using heat pumps for heat transfer and the ground for thermal energy storage.

Heat Pumps in District Heating

Heat Pumps in District Heating, published by DECC in February 2016, recognises the value of using heat pumps in District Heating to lower carbon emissions in place of central gas boilers or gas based CHP: Heat Pumps in District Heating.

Demand Side Response

Businesses can save money if they are prepared to be flexible in the timing of their demand for electricity: Demand Response.

CP1 Heat Networks: a Code of Practice

In response to DECC's desire to see an increase in the use of heat networks in order to reduce carbon emissions and reliance on imported fossil fuels, CIBSE has produced a Heat Networks: Code of Practice to encourage high standards. What are the implications?

CP2 Surface Water Source Heat Pumps: a Code of Practice

In response to DECC's desire to see an increase in the transfer of heat from open water to reduce carbon emissions, CIBSE has produced a Surface Water Source Heat Pumps: Code of Practice to encourage a high standard of installations.
