Sophia Haussener, Saurabh Yuvraj Tembhurne, Clemens Gregor Suter, Isaac Thomas Holmes-Gentle
The production of synthetic fuels and chemicals from solar energy and abundant reagents offers a promising pathway to a sustainable fuel economy and chemical industry. For the production of hydrogen, photoelectrochemical or integrated photovoltaic and elec ...
2023Thermodynamic modelling of hydrogen production in sorbent-enhanced biochar-direct chemical looping process
Hydrogen (H-2) has been widely considered the clean energy carrier of choice for emerging renewable energy generation technologies. However, H-2 is a secondary fuel mainly derived from natural gas. Over the past decades, research on developing H-2 producti ...
2022Economies of Scale in PEMEC and SOEC Manufacturing based on a Bottom-up Model
Under the scope of net zero emission, a large-scale deployment of renewable technologies, especially clean hydrogen technologies are required. Hydrogen is a clean fuel and an ideal energy carrier that can be used to store, move, and deliver energy. Nowaday ...
2022Solar Water Splitting Using Earth-Abundant Electrocatalysts Driven by High-Efficiency Perovskite Solar Cells
Michael Graetzel, Shaik Mohammed Zakeeruddin, Hong Zhang, Dan Ren
Hydrogen is considered as the "holy grail" for the energy community. One of the most promising strategies to produce hydrogen is to split water using renewable energy such as solar radiation. The abundance of water and solar energy enables the potential of ...
WILEY-V C H VERLAG GMBH2022Engineering of PEM-PEC photocathodes for solar-driven hydrogen production
Marina Caroline Michèle Caretti
Earth has always been in perpetual evolution, but today we must face its rapid change due to human activity. The intensification of industrial activities and transportation to support our modern lifestyles are the main causes of climate change and the adve ...
EPFL2022Redox dual-flow battery for combined electricity storage and hydrogen production
The energy transition towards a carbon-neutral and sustainable economy is one of the greatest challenges of the 21st century to combat global warming and pollution. The decarbonization process is affecting every sector of the economy (electricity, transpor ...
EPFL2022Optimization of the Hydrogen Network in an Oil Refinery
The stricter environmental and product quality regulations are pushing oil refineries to increase hydrotreatment and hydrocracking capacities to lower the sulfur contents in the products, thus leading to a higher demand for hydrogen. The efficient use of h ...
