A brand new whitepaper from Danfoss, the multi-national engineering group, highlights the huge untapped potential of extra warmth as a supply of vitality and calls on coverage makers internationally, together with the U.S., to speed up the usage of extra warmth throughout all sectors.

Each time an engine or machine runs, it generates warmth. Anybody who has felt the heat behind their fridge acknowledges that. The identical is true on a bigger scale in supermarkets, knowledge facilities, factories, wastewater services, subway stations and business buildings.
Extra warmth might be reused to provide a manufacturing facility with warmth and heat water or exported to neighboring properties and industries by way of a district vitality system which provides warmth to shoppers by way of a community of underground pipes carrying sizzling water. Such warmth networks can cowl a big space and even a complete metropolis or provide a small cluster of native buildings. Whereas the U.S. would wish to spend money on infrastructure and district heating methods, there may be low-hanging fruit in universities and hospital campuses to use this resolution now.
Based on Astrid Mozes, President, Areas, at Danfoss, recycling warmth isn’t solely an missed measure within the present vitality disaster, but in addition the subsequent frontier of the inexperienced transition within the U.S.
“The US is sitting on a gold mine of extra warmth,” Mozes mentioned. “Extra warmth is the world’s largest untapped supply of vitality and it’s all round us. Utilizing gasoline or electrical energy for heating is like utilizing a chainsaw to chop butter, as heating can simply be lined by low-value heating sources equivalent to extra warmth.
“Regardless of this unbelievable alternative – now we have essentially the most knowledge facilities on the planet – there are only a few initiatives pushing for extra environment friendly use of the huge quantities of wasted vitality within the type of extra warmth. And that is though we have already got the options obtainable to harness warmth. We urgently want new coverage measures to speed up the usage of extra warmth throughout the U.S., each in order that residents and companies can profit from decrease vitality prices and to make sure we pace up our progress within the inexperienced transition and decarbonize our economic system. Let’s make it occur.”
Using extra warmth can substitute important quantities of fossil fuels which can be in any other case wanted to supply warmth. Used this manner, extra warmth can assist stabilize the longer term electrical energy grid and thereby ease the transition to a inexperienced vitality system.But the potential of extra warmth isn’t even near being utilized and is just about ignored in coverage circles.
Reusing extra warmth is vitality effectivity in its purest kind
The whitepaper, entitled ‘The world’s largest untapped vitality supply: extra warmth’ assesses the potential of extra warmth as an environment friendly vitality supply. Based on the Worldwide Vitality Company (IEA), a world push for extra environment friendly use of vitality can scale back CO2 emissions by an extra 5 gigatons per yr by 2030 in contrast with present coverage settings.
A 3rd of the discount wanted in energy-related CO2 emissions this decade should come from enhancements in vitality effectivity, in response to the IEA internet zero state of affairs.A full implementation of applied sciences that faucet into synergies between totally different sectors and allow a utilization of extra warmth has the potential to avoid wasting USD 72bn (EUR 67.4 bn) a yr as soon as totally carried out in 2050.
“If we’re actually going to harness the potential of extra warmth we have to change our perspective on it and start to think about extra warmth as an vitality useful resource as an alternative of waste to be disposed of,” Mozes mentioned. A world push for larger effectivity can assist keep away from virtually 30 million barrels of oil per day. One of many first boundaries stopping us from reusing extra warmth consists of the lack of awareness. However we should additionally introduce financial incentives, coverage measures and prioritization of partnerships between native authorities, vitality suppliers and vitality sources to assist maximize the total potential of extra warmth.”
Toby Morgan, Senior Supervisor, Constructed Atmosphere, Local weather Group commented on the potential for extra warmth:
“The worldwide vitality disaster is a wakeup name to cease losing vitality, and Danfoss is correct to name for governments and corporates to grab the large potential of extra warmth. Now greater than ever we have to make higher use of the vitality we already produce, we merely can’t afford to let it actually escape out the window. Vitality effectivity enhancements, like capturing and recycling extra warmth, are completely essential to decrease fossil gas demand and decrease payments.”
