4 Energy Solutions Ltd. Experts in Energy Efficiency and Low-Carbon Heat

Renewable and Low Carbon System Integration  

Over 80% of UK and Ireland's residential energy use, is for heat. Individual gas and oil boilers serve much of this heat demand. Heat networks supply <2% of the heat market. The EU average is 10%.

 “Benefits of district heating include lower carbon emissions and fuel consumption, provision of a cost-effective means to eliminate waste and a reduced reliance on imports.”

Heat networks help decarbonise heat due to centralised plant efficiencies, other benefits are as follows:

• Integration of multiple heat sources, to suit the heat demand profile, tariffs, etc. 
• Easy deployment of advanced, sustainable, technologies, without supply disruption.
• Flexibility, where it is possible to recover heat and use it to deliver heat to others.

Full Life Cycle Cost Analysis and Project Financing

We set up 4 Energy Solutions to assist private companies and the public service with the energy transition. The goal of the business is to provide unbiased technical and financial consultancy services by:

• Identifying possible process and system inefficiencies
• Advising as to the range of effective renewable energy and energy efficiency measures which could be implemented for a specific site, process, etc.
• Providing detailed system designs and securing full solutions for our client, either using their existing supply change or by using our network of suppliers, installers, financiers, specialists, etc.
• Carrying out Full Life Cycle Cost Analysis, Payback Calculations, etc. for each energy management measure.
• Identifying possible state (incentives, grants, etc.) and private funding opportunities, where appropriate.

The Energy Transition

The UK’s heat sector accounts for 20% of national carbon emissions. It is critical we decarbonise heat to achieve ‘net zero’ carbon emissions by 2050. Heat networks and electrification are central to achieving this objective. 

The heat energy required for networks supplying, space heating and hot water (< 80° C) can be considered low-quality, compared to electrical energy. This identifies an energy imbalance – using electricity for low-quality heat applications; albeit green electricity.  

"The optimisation of heat networks is critical to minimise the consumption of high-quality, electric, energy to supply this low-quality, heat, demand."
