During the UN climate conference COP27, Enjay participated in the Dragonfly’s Den competition at the COP27 Climate Hub, an on-site and digital broadcast hosted by We Don’t Have Time from Sharm El-Sheikh in Egypt. Nils Lekeberg, Co-founder and Vice President of Enjay Systems joined the broadcast from Malmö in Sweden to talk about heat recovery in polluted air streams, like in restaurants.

Energy efficiency in buildings is crucial to solving the climate crisis. For every kWh of energy that we never use, we can prevent the environmental damage that comes from producing that energy. This is even more crucial as we are moving away from fossil fuels. As an example, one major way of increasing energy efficiency is by using a method called heat recovery, which means reusing the excess heat that is created from for example cooking food is reused to keep buildings warm. In Germany, heat recovery in offices and residential buildings saved about 55 TWh of energy. That same year, Germany bought 49 TWh of natural gas from Russia. In other words, without heat recovery in buildings, Germany may have needed twice the amount of natural gas from Russia.
Enjay is making use of this technology in an area where it has previously been impossible: What is called polluted air streams. For example, in restaurants, the warm air coming from the kitchen has previously been considered too polluted to be reused. With Enjay’s new heavy-duty heat exchanger, restaurants can reuse that heat to keep their dining room warm, for example, and in doing so lower the energy needed for heating by 90%.
This solution is ready to deploy, and there’s no drawback to implementing it. “The customer drive really is the wallet. What we have created is an economic incentive to help strive for the 1.5°C limit.” said Nils Lekeberg in his pitch. When asked about the payback period, he said: “If you install our technology in the new building stage, the alternative cost is very close to zero. If you do it as a retro-fit, it takes you about 18 months to pay it back.”
