Direct solar water splitting appears as a promising route to produce hydrogen avoiding competition for electricity against other important economic uses. Halogenated hybrid perovskites recently enabled the demonstration of efficient and potentially low-cost photoelectrochemical cells and PV-coupled electrolysers, reaching high efficiencies but so far limited to small active area of a few mm2 so far, in the case of perovskite/silicon tandem solar cells. Here, we show the added value of integrating a thermal exchanger into the system thanks to additive manufacturing, providing a thermally integrated photoelectrochemical cell (IPEC) with performance doubled against the device without any heat exchanger (from 3.3 to 8 % STH). In addition, we develop a modular approach to up-scale this concept from 7.6 to 342 cm², highlighting statistical variations in efficiency of single integrated photoelectrochemical cells and their origin. We conduct an outdoor stability test for 72 hours, with a STH performance of 6.3 %, and investigate the causes of device degradation through the easy disassembly of the integrated photoelectrochemical devices. We identify the interface between perovskite layer and p-layer as critical for reaching stable photoelectrochemical devices integrating perovskite/silicon tandem solar cells.

“…We acknowledge the fact that although H 2 produced via water electrolysis with renewable energy (e.g., offshore wind energy) input is labeled as green with no CO 2 emissions along the production chain, some offshore wind platforms have diesel generators installed for specific operational needs, such as during commissioning. Recently, the concept of "golden hydrogen" has been put forward by Lubbe et al [6] for H 2 produced in dedicated solar generators.…”

The coupling of methane pyrolysis with the gasification of a solid carbon byproduct provides CO2-free hydrogen and hydrogen-rich syngas, eliminating the conundrum of carbon utilization. Firstly, the various types of carbon that are known to result during the pyrolysis process and their dependencies on the reaction conditions for catalytic and noncatalytic systems are summarized. The synchronization of the reactions’ kinetics is considered to be of paramount importance for efficient performance. This translates to the necessity of finding suitable reaction conditions, carbon reactivities, and catalysts that might enable control over competing reactions through the manipulation of the reaction rates. As a consequence, the reaction kinetics of methane pyrolysis is then emphasized, followed by the particularities of carbon deposition and the kinetics of carbon gasification. Given the urgency in finding suitable solutions for decarbonizing the energy sector and the limited information on the gasification of pyrolytic carbon, more research is needed and encouraged in this area. In order to provide CO2-free hydrogen production, the reaction heat should also be provided without CO2. Electrification is one of the solutions, provided that low-carbon sources are used to generate the electricity. Power-to-heat, i.e., where electricity is used for heating, represents the first step for the chemical industry.
