1. Together with the external consultant validation and aggregation of different reference cases for the SOcool packages, based e.g. on SHC Task 48.
2. Literature study on previous solar cooling projects.
3. We asked Solargis to prepare an innovative map comparing direct normal irradiance (DNI) and global horizontal irradiance (GHI).
4. Design of the five SOcool packages P1 to P5 (Product Plan), providing highly energy and cost efficient and scalable solutions for each package.
5. Discussion with chiller manufacturers and others about economic sweet spot and cost curve over scale.
6. Price benchmarking of our resulting packages P1 to P5 against the reference cases.
7. Selection of typical markets for the feasibility study (Case Study).
8. Based on standardized questionnaire, collection of detailed framework conditions for Marketing Study (energy prices, renewables incentives) in the selected markets, using agencies and selected agents as well as own travel (to Dubai, India, China).
9. Strengthen links with existing partners such as chiller manufacturers, identify additional collaborative partners in the markets, discuss strategic demonstration plants and pilot studies and opportunities.
10. Development of a detailed demonstration strategy to be formulated based on discussion with potential collaborative partners, including developing pilot trial methodology (according to SHC 48), with the aim of maximizing market awareness and acceptance; conducting target customers groups interviews/ surveys.
11. Strategic decisions on attractive packages and markets (Road Map).
12. Forming collaborations with the most suitable suppliers.
13. Preparing a feasibility study report in long version (65 pages with approx. 50 pages attachments). Based on that we prepared the short 20 page report.
Main results are:
The literature study shows attractive applications and configurations of solar cooling, but also that the SunOyster has to achieve significant cost reductions in solar cooling (which it can, as shown below).
Both electric and thermal chillers have advantages. For the SunOyster, thermal chillers are more attractive because they allow a good use of the heat in permanently warm climates or during the summer season. Among the thermal chillers, small Lithium Bromide (LiBr) absorption chillers with in-built fan are the best option for smaller scale air conditioning, ammonia chillers for refrigeration and more efficient double stage LiBr chillers for larger air-conditioning.
The project developed a marketing plan for considering markets are attractive for SunOyster cooling. This is defined by the following five criteria:
- An innovative map prepared during the project shows where the direct normal Irradiation (DNI) needed by the SunOyster is better than the global horizontal Irradiation (DNI) which is relevant for conventional solar PV and thermal equipment (see attached Image 3). Whereas the equator regions are not favourable, there are broad sun belts north and south of the equator which are favourable for the SunOyster.
- Cooling demand can be expressed in cooling degree days. Many areas in the sun belts have a high cooling demand.
- Countries with large cooling markets such as China, US and India are more attractive.
- Markets with higher energy prices such as e.g. Italy are more attractive.
- Positive framework conditions for solar energy support SunOyster cooling.
-We have summarized these factors in the attached Image 4. First target markets of the SunOyster are Italy and India.
In the case study, we identified for the markets Italy (Catania) and India (Mumbai) attractive applications. For the small scale applications in Italy we attach Image 5 and for the large scale applications Image 6. Because of higher radiation and energy costs, Italy is even more attractive than India. Attractive applications for the SunOyster are in particular family houses with swimming pools, offices, cold storages and Hotels (see in detail the text field below).
