HyCool 7th General Assembly in Barcelona

15 de November de 202115 de November de 2021 by AdminCometPublishing

After two years, and the COVID_19 lockdown consequences, the HyCool consortium has met again in person, to hold the 7^th General Assembly in Barcelona. The event has been organized by the Project Coordinator Veolia and IDP Ingeniería during the 9^th and 10^th of November 2021. The objective of the Assembly has been to review and update the project progress and to discuss the final steps in a moment where the project is near to the commissioning stage.

The project has suffered several delays because of the COVID_19 crisis and for other consequences of it regarding the civil works execution, the limitations on the logistics and transport of the equipment from different points in Europe (Austria and Germany) to Spain where the pilots are being installed, and even, the availability of some of the core materials for the solar field installation. Nevertheless, the current situation is optimistic as almost 85% of the pilot works in Givaudan and Bo de Debó are completed including civil works, installation of equipment and the solar mirrors.

During the first session, work package leaders presented the progress made with the core technologies focused on the installation of the equipment, the demonstration activities, the exploitation, communication, and coordination activities.

HyCool Consortium during the 7th General Assembly

After the project coordinator Veolia welcome words, the partners involved in the manufacturing of the equipment, installation processes and the Pilot Site representatives discussed about the commissioning and demonstration stages next year when the project shall be closed. Up to now, the delays are minor and depend on some circumstances regarding adjustments and integration of the systems with the Energy Management system implemented by Ecotherm.

Many interesting results have been obtained and now work packages 7, 8 and 9 that cover environmental and socio-economic analysis, exploitation and communication activities may progress towards the planning of workshops, communication of energy management simulation tools available on the HyCool website, the potential commercialization of the technologies designed and implemented, and the visibility of the companies that have made conscious decision at introducing renewable energy in the industrial field. During the WP9 about communication and dissemination activities, COMET and the partners discussed about the coming events, workshops and training sessions based on Virtual Reality implemented by AIT, IDP and the support of Ecotherm and Fahrenheit.

During the visits to the pilot sites, the partners could see the installations at Givaudan, the visit was focused on the solar field and the Ecotherm technical room. Ecotherm explained the process about the generation of steam and hot water from the solar energy collected in the solar panels, and the pending works until the commissioning.

R2M also took advantage of this visit to scan the technical rooms and solar field with the Matterport camera to improve the virtual reality environment and some of the exploitation and commercialization activities planned. These results will be shared in further press releases and newsletters of the project.

This is the first face-to-face meeting after COVID_19 crisis and with the works performed in a very finished stage. Next Assembly will be held in Germany around May 2022, but some visits and actions to the pilot sites shall happen in between.

HyCool Project is in its final stage and 2022 will make possible to demonstrate how efficient and profitable is the HyCool and thermo-solar energy in industry.

Hybrid heat pump for industrial applications: experimental characterization and optimal configuration

9 de June de 2021 by AdminCometPublishing

How to turn solar heat and industrial waste heat into useful cooling effect? Industrial processes are often energy-intensive and the need for their efficient decarbonization is now at the forefront of governmental and corporate policies worldwide. However, solutions for the green transition of the industrial sector should be:

Flexible
Widely applicable
Reliable

And should:

Minimize energy consumption
Reduce operational costs
Lower CO2 footprint

Is there a solution to all these answers? Heat pumps are the fit match to tackle these issues.

Within HYCOOL, CNR ITAE and Fahrenheit have developed a hybrid thermal heat pump for application in several industrial sectors where efficient and sustainable cooling is needed. But what is the hybrid heat pump?

The hybrid heat pump concept

HYCOOL system proposes the combination of a thermal heat pump with an electrical heat pump: the thermal heat pump exploits low-temperature waste heat (i.e. 70-90 °C) that is generally unused or dumped to the ambient. It can also be powered by renewable sources, such as solar heat and biomass. The electrical heat pump can exploit electricity locally produced (i.e. from PV panels or other sources) and thus further increase the share of renewables. The hybridization consists in the configuration of the two heat pumps: they can work in series, in parallel or in cascade by just changing the hydraulic connections. This makes HYCOOL configuration flexible and easily adaptable to different industrial cases.

In the framework of HYCOOL, two case studies are considered, which are shown in Figure 1:

At GIVAUDAN (chemical industry), process cooling at +5°C is needed. To achieve this target with an overall high efficiency, the base load is covered with an adsorption unit (80 kW nominal power) that cools down the fluid in the range 5-21°C. Peak load is supplied by a compression unit with a natural refrigerant (propane, R290), that is connected in series with adsorption unit.
At Bodedebò (food industry), cooling of food at -10°C is needed. In this case, the efficiency in cooling generation is achieved by using a cascade configuration: the thermal heat pump (adsorption) is used as topping stage for the electrical heat pump, in a two-stage system. This increases the efficiency of the electrical heat pump up to 40% at the expenses of renewable or even waste low-grade heat, so virtually without the need for extra cost.

Figure 1: HYCOOL flexible configuration of the hybrid heat pump.

Experimental evaluation of the hybrid heat pump

The hybrid heat pump was tested in the laboratories of CNR ITAE in Messina in design and off-design conditions (see Figure 2). The aim of the tests was to define the cooling power and electricity consumption of the hybrid heat pump in the different ambient and process operating conditions, as well as confirm the reliability under off-design conditions. To this purpose, more than 100 testing cases were evaluated, and the results were reported in form of performance maps, like those in Figure 3.

Is HYCOOL solution feasible for you?

HYCOOL solution is widely suitable for a vast range of processes. To know whether solar cooling can be part of your industrial processes, a screening tool, based on process requirements and information on the solar radiation in your industry’s location, was realized and is accessible here:

HyCool Pre-feasibility Simulator

The results of the experimental testing at CNR, instead, were used to compile a calculator to predict the refrigeration capacity and energy efficiency ratio (EER) of the cascade HYCOOL chiller for a given industrial cooling process. You can access the tool here:

Start of the Works to Launch the Pilots

8 de February de 202123 de October de 2020 by AdminCometPublishing

At the end of last September, the pilots of the HyCool project (Industrial Cooling through Hybrid system based on solar heat) began their way to start-up. In this initial phase of project execution, the two demonstration sites have started the civil works with which the necessary infrastructures are built to house the equipment and all parts of the system. These works are developed on the following fronts:

Givaudan: installation of the solar field on a plot adjacent to the plant; construction of a prefabricated technical room next to the solar field that will provide water vapor to the production plant from solar energy and with the technology supplied by Ecotherm; construction of the technical room that will supply cold to the plant, using adsorption pumps built by Fahrenheit.

2. Bo de Debó: installation of the solar field on one of the warehouses of the production plant; construction of the technical room that will house the hot and cold water production system using using Fahrenheit hybrid heat heat pumps and Ecotherm solar technology

The construction works are expected to be completed by the end of November 2020, giving way to the installation and commissioning stages of the HyCool systems, whose commissioning is expected in mid-June 2021.

Meet the Pilot Sites: Givaudan

26 de January de 20213 de July de 2019 by AdminCometPublishing

Article by Givaudan

By maximising the use of renewable energy through its unique technology, HyCool aims to minimise greenhouses gas emissions. Givaudan, which itself has a target of reducing absolute Scope 1 and 2 GHG emissions by 30% between 2015 and 2030, is proud to host one of the project’s two pilot sites at its Sant Celoni plant. Givaudan spoke to Jorge Vilaseca, local Project Engineer, to get an update.

HyCool Pilot: Givaudan’s Sant Celoni Site

Why did Givaudan decide to participate in this project?

The idea was to test HyCool in at least two industries using significant amounts of cooling in their
processes and Givaudan offers a great profile to host one of the pilot sites as a representative of
the chemical industry. We couldn’t pass up the opportunity to participate in this innovative project.
HyCool is particularly attractive to Givaudan for two main reasons. First, our sustainability strategy
A Sense of Tomorrow includes ambitious environmental targets. This project will help us reduce
GHG emissions by a projected 3% for the site and decrease energy consumption in terms of
electricity and gas, helping us towards our goal of 100% renewable electricity by 2025. The
project is totally aligned with our sustainability strategy. Secondly, every Givaudan production
plant needs heating and cooling, and it would be relatively easy to replicate this technology.
HyCool should deliver refrigeration with 25% greater efficiency—this would provide Givaudan a
competitive advantage.

How far along are we in the project?

We have finished the conceptual phase: we have decided where and how to use the cooling
produced, where to install equipment and how to connect it. Now we are looking at detailed
engineering: how to best connect materials, figuring out the best design for the electrical
connections, etc. The one-year installation phase will then start this summer.

What requirements did Sant Celoni have to take into account when planning installation?

One issue was finding a place to install the solar collectors. They require more than 1, 000 m2 of
surface, preferably over a roof. Because of a lack of surface on our buildings, and for safety
reasons, mainly the presence of flammable products, this wasn’t possible, and we had to install
the solar field at ground level. This caused problems such as how to manage shadows of other
buildings that we had to solve.

We also have to comply with all EHS requirements including ensuring a good works plan for
execution. We expect a number of external contractors and companies on site during installation
and we will need to monitor all aspects of their work. We will need to ensure a pre-start safety
review, issue corresponding work permits and make sure we prevent injuries and accidents: we
want to ensure that “Everyone gets Home Safe Everyday”.

Givaudan, which itself has a target of reducing absolute Scope 1 and 2 GHG emissions by 30% between 2015 and 2030, is proud to host one of the project’s two pilot sites at its Sant Celoni plant.

How did consortium partners contribute?

During the initial phase, we worked closely with the equipment companies and engineering and
general contracting partners. This has been a real team effort.

What are the next steps for Givaudan as a pilot site?

The next steps are to finish the installation on time, on budget and safely and then to operate the
machinery and collect data on energy efficiency and ease of use. We have two years of hard work
ahead, but it will be stimulating. As to transferring the technology to other sites – why not? If it is
cost effective, we will be able to use it in countries with even more favourable weather conditions
such as Mexico, South Africa or Singapore.

Industrial Cooling Based on Solar Heat at the Demo Sites

26 de January de 202119 de June de 2019 by AdminCometPublishing

Article by Alex Grande, from IDP

Powering of industrial processes, if based on renewable technologies, may offer greater potential for CO₂ emission reductions. Solar thermal energy is a promising sector which has been widely studied during the last two decades, becoming a candidate of the highest potential among renewable energy technologies, especially for industrial heating and cooling processes, because some technologies, such as heat pumps and mechanical vapour recompression, are particularly effective in hybrid systems.

The use of direct solar heat in industry is often hampered by barriers like lack of nearby available surface and seasonal imbalances. However, recent solar steam developments applied in the cooling demand services is growing worldwide with a wider variety of use, mainly within the industry. Some technologies, such as heat pumps are particularly effective. The two demonstration sites selected to tests Hycool system (Bo De Debó and Givaudan) are industries where custom-designed packages will be built, installed and tested.

Bo De Debó is a specialised industry in preparing precooked fresh dishes based on meat, fish and vegetable products, for being frozen, vacuum-packed or canned, and then sealed. In this site, Hycool will pre-cool the water in a buffer tank where it should be cooled down with other chiller in order to get 3-5ºC needed for the production of “gazpacho” (a kind of vegetables juice) and food washing processes. The residual heat from the system will be used to produce hot water for cleaning operations.

Givaudan is the global leader in the creation of flavours and fragrances. In close collaboration with food, beverage, consumer product and fragrance partners, Givaudan develops tastes and scents that delight consumers the world over. The Hycool system will provide the cold water needed to refrigerate the glycol stored in a buffer tank before it’s pumped to the vacuum pump water rings. The residual heat from the system will be used to produce steam to be injected in the factory net.

The old chilling system that will be substituted for the Hybrid Heat Pump from the new Hycool system, in Givaudan facilities (Sant Celoni – Spain).

In summary, the solar thermal energy provided by the Hycool System will allow our pilot sites:

To reduce their productions costs by using a free source of energy
To increase their system efficiency by using the residual thermal energy for producing heat water or steam
To reduce their global CO₂ emissions by reducing the use of fossil fuels for producing that heat
