Optimising energy and cost performance with CHP

Optimising energy and cost performance with CHP

With energy costs spiralling to new highs, businesses and public sector organisations have a strong incentive to look at how these costs can be reduced.

Getting your space heating and hot water free isn’t an option (there’s no such thing as a free lunch) but the use of combined heat and power (CHP) in a properly designed system can certainly help reduce the cost of both heat and electrical power.

The emphasis here is ‘properly designed’ as CHP will only deliver real savings when the system is optimised for it. That’s why it’s essential to work with experts like Hoval, that has many years’ experience of getting the most from systems that include CHP.

Clearly the advantage of CHP is that, whilst its key purpose is to produce heat, it can also generate electricity at the same time (cogeneration), with no extra use of fuel. That electricity can then be used in the building or exported to the national grid. The key is to ensure there is sufficient heat demand to run the CHP engine for long periods of time (ideally 24 hours). Typically, the CHP will be sized to meet the base heat load from the building, with other heat sources (boilers, heat pumps, solar thermal) ‘topping up’ as necessary.

So, crucially, the CHP is heat-led and must have sufficient loads to make running it worthwhile – with any power generated a bonus that will certainly save money and contribute to a return on investment in the CHP.

From an environmental point of view, it’s also worth noting that Hoval has CHP engines capable of running on hydrogen and BioLPG, so there is also an opportunity to reduce carbon emissions. All of which contributes to future decarbonisation.
