• Chemical process intensification can improve the energy efficiency of chemical production. • The intensification of chemical processes reduces the consumption of raw materials and energy. • Chemical process intensification can help reduce the amount of waste and emissions. • The intensification of chemical processes can encourage innovation and the development of cleaner technologies. • Chemical process intensification can improve safety and health in chemical production. The 2030 Agenda is a call to global action to eradicate poverty, protect the planet and ensure prosperity for all. Process intensification, in this context, refers to improving the efficiency and effectiveness of production and service processes, in order to reduce environmental impact and improve people's quality of life. By optimizing and consolidating various steps within a production process, process intensification aims to achieve higher yields, reduced waste, and lower resource consumption. This approach aligns with the sustainability goals set by the United Nations, including: energy efficiency, waste reduction, resource conservation, emission reduction, circular Economy and sustainable development. Process intensification primarily impacts Goals 7, 9, 12, and 13 of the United Nations' 2023 Sustainability Agenda due to its potential to address key aspects related to energy, industry, sustainable consumption and production, and climate action. This review shows how process intensification directly impacts those Goals of the 2023 Sustainability Agenda by promoting affordable and clean energy, fostering innovation in industry, encouraging responsible consumption and production.

• Power to heat is an effective option to decarbonize endothermic chemical processes. • Induction heating, Joule heating, Microwave heating and RDR reactor reviewed. • Open challenges and perspectives for scale-up and implementation of these systems are analyzed. The rising environmental problems and demanding actions aimed at mitigation of climate change are calling for a radical transformation of different industrial sectors. In this perspective, chemical process industry is called to play a major role towards this transition, on one hand by transforming its existing carbon-intensive processes and, on the other hand, providing clean alternatives for hard-to-decarbonize applications. Among the possible options for the transformation of catalytic processes, power-to-heat is considered in view of large available quantities of green electricity. This approach is considered industrially-mature and can be applied at a large scale for a wide number of existing processes, providing substantial advantages in terms of intensification. The aim of this work is to provide a detailed analysis of the status quo of these technologies and critically discuss them towards their possible use for a generic process of interest by the identification of several key indicators. The main technologies proposed i.e microwave heating, joule heating, induction heating and roto-dynamic reactor are reviewed alongside with some of the applications already reported in open-literature. Afterwards, a critical analysis about material needs, energy efficiency of the proposed methodologies, the possibilities of scale-up and retrofitting and the impact on the overall process design and performances are reported.
