WP04 will adopt process integration methodology to characterize process energy demands, at company and sector level. Using these profiles, identification and assessment of integration opportunities for renewables, after implementation of economical energy efficiency measures, will be conducted. Additionally, quantification of opportunities for excess heat usage and substitution of fuels/heat with negative emission technologies to fulfil the residual heating demand will be assessed. Practical tools and methods will be developed for practitioners to ensure high implementation potential in the Swiss industry.
