Are you already worrying about the coming summer, how to keep your place and products cool? Want to avoid the situation of last summer? Last Friday, I gave a webinar for the Indian Government, the NPC agency. I proposed an innovative approach of 3 new technologies & business models. Specifically it was the combination of

1. A chiller with ice storage rather than a chiller with a big electric battery. After all, why do Demand Side Management (DSM) with a Li-Ion battery if cold can be stored in an ice bank?

2. Dynamic electricity tariffs instead of only night/day. It seems to me that the USA electricity market is more developed in the sense of retail & corporate access to dynamic pricing. I saw an interesting article about that in the International Energy Agency (

3. If suitable, an Internal Combustion Engine (let’s avoid the abbreviation ICE :-) as driver of the chiller instead of using an electric motor. The engine heat goes into an additional (absorption) chiller.

The Indian participants were interested in my recommendation to start pilot projects with this double/triple innovation for consumers where Security of cold Supply is essential. For example hospitals, food logistic centres, hotels. What about your situation, what do you expect this summer?

Please give your comments, also on the feasibility of idea nr. 3, which I checked with a leading Indian chiller supplier. I will monitor this site and am curious about the reactions! We in Switzerland are less concerned about heat waves but in the USA there might be several opportunities.
