Description : This study dedicated to the potential integration of solar heat energy in industrial processes aims to provide a first level of information on the technical and economic feasibility of these solutions.

At the global level, heat consumption for industry represents nearly 24% of final energy consumption, all uses combined, and all energy carriers combined. This corresponds to nearly 24,000 TWh. By distinguishing the temperature levels, it is possible to consider solar heat technologies that could provide part of the supply for this energy consumption.

The study is composed of 4 parts: 

• The first part is dedicated to a state-of-the-art of solar heat technologies (collectors, storage, and operating principle) that can be used to supply heat for industrial processes. Thermal storage technologies, which are rarely dissociable from solar collectors, are also discussed.
• The second part deals with the methodology required to integrate solar heat.
• The third part is dedicated to the economic aspects.
• The fourth part presents four detailed projects sheets allow to discover solar heat installations integrated to industrial processes. They illustrate the diversity of solutions that can be implemented to meet different objectives.

In summary, this study found:

• The need to conduct detailed energy analyses to promote the integration of solar heat energy and to use the most appropriate technology,
• The diversity of solutions address a large part of the industry's low and medium temperature heating needs, depending on their level of maturity,
• The competitiveness of the cost of solar heat compared to conventional solutions and especially their insensitivity to changes in the energy market, given their very limited operating costs,
• An environmental impact 10 to 20 times lower than natural gas.

Description : To achieve the carbon neutrality in 2050, CO2 capture and storage (CCS) solutions will be necessary. This study focuses on the potential for creating CCU hubs, structures that bring together CO2 emitting and consuming industries, in order to improve the cost-effectiveness of the solutions deployed.

Several conclusions were drawn from the study :

• CCU remains a partial tool for decarbonization
• The study has shown the relevance of CCU hubs with regards to the need of reducing residual CO2 emissions, even if these solutions also present technical, economic and environmental challenges:
• A wide variety of CCU hub profiles was identified during the geographical analysis
• Depending on their uses, the hubs whose development will be favored in the short term will be those focused on "mineralization" use; hubs with "e-fuels" use and organic synthesis will be developed in the longer term.
• As the hub approach presents specific risks, it is necessary to find adapted business models to control them.

Description : Energy prices significantly increased since the end of 2021. Prospective scenarios from various organizations, conducted prior to the current geopolitical crisis, also predict a long-term upward trend for natural gas, coal and oil.

This study compares production costs between 2020 and 2030 for five industrial sectors with different energy price trajectories. To mitigate these effects, several solutions exist today.

This report focuses on the following six options:

• Flexibility solutions
• Energy efficiency actions
• PPA / GPA contracts
• Self-consumption
• Local energy communities
• Green energy supply contracts

Several criteria were considered in order to evaluate their relevance.

Description : This state of the art conducted by ALLICE aims at studying the technologies available to industries to convert industrial waste heat into electricity, when there is no possibility to recover it in direct form.

It lists the different technologies available, studies their advantages and disadvantages and draws up a summary table.

Each technology has preferred uses and sectors depending on the level of available waste heat and the desired electrical power.

Description : France is committed to achieving carbon neutrality by 2050. To achieve this goal, one of the levers is better recovery of the waste heat dissipated by industry during product manufacturing stages. A study carried out by ADEME in 2017 identified a considerable source of energy lost in thermal form - this energy coming from manufacturing processes.

It appears that a large part of this quantity of heat offers the advantage of being already channeled (chimney) at the exit of thermal processes before being evacuated to the atmosphere. In the vast majority of cases, it is therefore possible to capture this "free" energy just before it is dissipated into the atmosphere - especially since the high temperature level, generally > 200 °C, allows a wide range of technological solutions for heat recovery. From a market point of view, these solutions are still too little deployed - especially among small and medium-sized companies.

The objective is therefore to increase awareness of heat recovery technologies available to industry and to remove the many obstacles to implementation and investment: lack of knowledge of the technologies available, of energy and decarbonization issues, and even of accessible financing, or even the fears of industry about the medium-term sustainability of installations.

The study focused on three areas :

• An inventory of available heat recovery technologies,
• A technical and economic analysis of the conditions for the implementation of these technologies on industrial sites in the form of 6 specific technology sheets,
• An analysis of energy issues to identify promising industries in terms of deployment of these recovery solutions.

The study focused on mature technologies (TRL 7) that are commercially accessible to industry.
