Our technology partners EC Power have written an excellent piece for the Danish newspaper Berlingske on how CHP combined with a Heat pump can help to halve energy costs*. Have a read of the translated piece below:
Despite the war in Ukraine, gas is becoming greener, and properties can even halve their gas consumption by connecting a micro-CHP plant and heat pump from EC POWER, which has been on the market for 30 years.
How would humans design their overall energy system if or when they one day settled on Mars and had to build a society from scratch? This is a hypothetical question that Bjarne Bogner has been addressing for three decades.
He is CEO of EC POWER, which he founded 30 years ago. But there are still many people who benefit from EC POWER’s way of thinking about energy production and supply. Then as now, the company’s core product is the XRGI® gas-fired micro-CHP plant, which is installed where there is already a gas boiler. The micro-CHP plant powers a heat pump which is more energy efficient, the total installation in a customer’s property – the combination of gas boiler, micro-CHP plant and heat pump – can halve the amount of gas initially needed to produce energy for the property.
By generating power where it is needed for a heat pump, XRGI® ensures that society does not have to expand its electricity infrastructure.
EC POWER was created with the vision that larger buildings such as schools, hotels, care homes and apartment blocks could have a much more efficient energy supply instead of having one or more furnaces running in the basement. EC POWER will harness both solar and wind power, as well as the even greener gas that will only continue as we get better at harnessing animal and human waste to make biogas.
Today, XRGI® micro-CHP plants are located around Europe, making a difference that is both green and cost-effective. This is happening in properties with larger gas boilers. Here, EC POWER adds an XRGI® micro-CHP plant and a heat pump.
A case from Absalon Skolen in Holbæk, which got an XRGI® micro-CHP plant and a heat pump in 2019, shows that the payback time has gone from five years at the time to three years at the prices we have now.
Although pure natural gas will be phased out over time, there will still be plenty of gas, explains Bjarne Bogner, and there will increasingly be green gas to support the green transition.
