Hydrogen production via electrochemical water splitting is a promising area for storing solar energy. For this technology to be economically competitive it is crucial to develop water-splitting systems with high solar-to-hydrogen (STH) efficiencies. Usually, expensive solar cells or costly semiconductors are used for this. Now (2021), scientists at the Brookhaven National Laboratory have demonstrated that modifying the top layer of...

Modern life relies heavily on the efficient functioning of catalysts. They can improve chemical reactions, are indispensable in many industrial manufacturing processes, and can even contribute to reducing emissions. They are also an integral part in battery design and transportation. It is all the more astonishing, therefore, that the exact mechanisms of a catalyst are still not entirely understood by science. Now (2021), scientists...

Hydrogen is counted among the cleanest and most sustainable energy sources as it does not release harmful emissions into the atmosphere and can be employed in many industry sectors, including transportation and power generation. Effective technologies for transporting and storing hydrogen are paramount to a well-functioning hydrogen economy, but contemporary means to do so are expensive and susceptible to contamination. Therefore,...

Hydrogen energy is generally considered to be one of the cleanest energy sources and shows great potential to become a major player in the energy market as it has high energy conversion efficiency and causes fewer emissions of CO2. It is a highly flammable material that can be used to heat homes, water, and even power engines. Now (2020), transmission system operators in Germany have created a concept for the establishment of a grid...

Concentrating Solar Power (CSP) plants have been in use for energy production for a long time. Among the commonly used designs are parabolic trough systems, which employ heat absorber tubes along curved concentrating mirrors to absorb solar energy. During this process the organic-based fluid that delivers heat from the parabolic trough receivers to the electricity-generating steam turbine undergoes a small but constant thermal...

The creative association Advanced Energy Technologies has presented a map of the global energy hydrogen infrastructure. The compilers have attempted to demonstrate on a small map of the world the main statistical indicators of the production and use of hydrogen for energy purposes, to display the largest or most notable infrastructure facilities, and to present a list of regional and national development programs. The main purpose of...

Negative cash flows from operating and investing activities and negative working capital in 2018 let the company doubt whether it was able to continue as a going concern. In 2019 the company restructured its management team, raised capital under the at-the-market sales plan, which allowed accounts payable to be paid off. While some of the indicators of substantial doubt still exist, such as historical losses and negative cash flows,...

Scientists have been searching for years to find materials which do not need precious metals to produce active and stable reactions in order to discover alternatives to fossil fuel in energy production. The oxygen evolution reaction (OER) is a vital part of many of these reactions where water is split in electrolysers to produce hydrogen that can power fuel cells. Now (2020), scientists at the U.S. Department of Energy’s (DOE) Argonne...

Hydrogen is a very simple and abundant element on earth as it consists of only one proton and one electron. Hydrogen is able to store and deliver usable energy, but it does not typically exist by itself in nature and must be produced from compounds that contain it. It is an indispensable element in promoting the transition to renewables and meeting climate targets. It is also the essential building block of sector coupling. While it...

Producing sustainable and environmentally friendly fuels has been one of the main interests of scientific research for many years. Scientists have come up with many effective solutions to achieve this goal. One of the most promising technologies is harvesting solar energy with the help of semiconductors which can initiate surface electrochemical reactions. This kind of reaction needs extremely stable and active catalysts, particularly...
