An Austrian project will use blockchain to find residual heat points in the cities of Vienna and Graz.
Launched by the Austrian Institute for Technology (AIT) on May 12th. HotCity creates a gamification system to power the city’s hot spots and channel them for public heating.
The platform will use the Ignis blockchain, which is part of the Ardor ecosystem developed by the Swiss company Jelurida.
Sustainability in Austrian cities
Vienna has one of the largest district heating networks in Europethat supplies hot water through central heating pipes in the city.
One of the advantages of this system is the ability to use residual heat from industrial processes to supply energy to consumers.s. This has an obvious impact on energy efficiency and CO2 emissions. Viennese energy suppliers claim that this system reduces energy consumption by 75%.
“Additional energy districts”, which produce more thermal energy than they consume, can generally feed some of this residual heat into the network and thus increase efficiency.
While large heat sources such as large factories and data centers are easy to identify, the smaller sources remain unused.
So the project HotCity would help create accurate and detailed records that could help improve urban planning in Austria. The project received a grant of EUR 310,000 from the Austrian Federal Ministry for Climate Protection, Environment, Energy, Mobility, Innovation and Technology.
Dr. Ernst Gebetsroither-Minder, head of the AIT HotCity project, told Cointelegraph that Vienna will produce an estimated 400 gigawatt hours of usable waste heat. While not everything will be cheap, the HotCity project is about:
“The idea is to develop a method with gamification to assess potential […] Crowdsourcing does not recover the residual heat, but “only” shows the existing potential. “
How it works
The purpose of the HotCity platform is to make the collection of the necessary data “voluntary and free time”. Reward users with tokens that can be exchanged for goods and services. Citizens can send the information with an application by doing physical inspections on site or even scanning photos and Google Maps.
As Gebetsroither-Minder explained, the blockchain is used to both secure and private data, while facilitating the exchange of tokens on certain coupons..
He speculated that the use of blockchain could go beyond:
[Blockchain] It could also be used by prosumers (small waste producers) to sell their waste energy using smart contracts and blockchain. However, this use of the blockchain to sell waste heat is not implemented in HotCity. “
The project will be tested in Vienna and Graz for the next heating season in October 2020 after the plans for a pilot project in 2020 were delayed by the coronavirus pandemic.
