Hylight launches hydrogen-powered airship

In order to monitor sensitive infrastructure, such as gas pipelines and high-voltage lines, Hylight suggests substituting helicopters with an airship operating in zero-emission mode.

And in this instance, it is a tiny airship. This hydrogen-powered device, which weighs 10 kg, can complete missions in flight for 20 hours. All are emission- and noise-free. In addition to being less expensive than a helicopter or an airplane, Hylight provides equipment for data collection and processing (4K cameras, infrared, and lidars).

Following battery testing, the start-up ultimately decided to use hydrogen to increase the range. Recent events in the Lombardy region of Italy saw the maiden flight.


IIT Jodhpur team develops new materials to make high-purity hydrogen

To create high-purity hydrogen through artificial photosynthesis, researchers at the Indian Institute of Technology Jodhpur have created perovskite nanocomposite materials based on lanthanides.

Hydrogen is expensive and out of the reach of the average person because more than 90% of its source comes from petroleum feedstock. The research group at IIT Jodhpur is looking for a reliable source for producing hydrogen. The IIT Jodhpur team’s invention just requires sunlight as an external energy source.

The method is straightforward, utilizes a large spectrum of sunlight, and produces hydrogen without the use of an external energy source. A crucial first step in using hydrogen as a fuel for cars directly, eschewing fossil fuels and lowering emissions, could be to produce it cheaply and with great purity.

The Department of Science and Technology and IIT Jodhpur are funding this innovative study together.


Wuppertal Institute conducts the H2 study

A significant study on hydrogen is being conducted at the Wuppertal Institute. The University of Bremen is in charge of implementing this in northern Germany. The topic is how hydrogen can eventually take the place of coal or gas as a source of energy. The use of hydrogen should be widespread and climate neutral. The sub-project “Conception of a supra-regional hydrogen economy as a socio-technical transformation of industrial centers” is headed by the Wuppertal Institute. The project involves a total of 17 institutions across the country.


A new way to generate hydrogen: via depleted oil wells

Researchers have found a fresh method for producing hydrogen gas. According to the American biotech startup Cemvita Factory, this raw material can be produced by introducing bacteria to depleted oil wells. This implies that the so-called “golden hydrogen” can potentially be extracted in thousands of different locations.

The residual hydrocarbon residues from the (often useless) oil induce a chemical reaction that produces hydrogen gas when a unique material made of particular bacteria and nutrients is injected into them. This was discovered by Cemvita Factory in July during a small-scale test. The business is now disclosing its findings, which it calls a “fantastic success.”

Charles Nelson, a firm official, asserts that there are 1,000 oil wells in the US alone that can (at least in theory) produce hydrogen in a similar manner despite the fact that no bigger testing has yet been conducted. The organization still needs to figure out a technique to prevent the CO2, which is produced along with the hydrogen, from entering the atmosphere in order to do this. The business is reluctant to disclose precisely which microorganisms and nutrients are present in the product. Nelson did mention that the business plans to manufacture the golden hydrogen for $1 per kilogram.

A sustainable substitute for gasoline, hydrogen gas can be produced in a number of ways. It is already conceivable, for instance, to use fossil fuels (‘grey hydrogen’), natural gas (‘blue hydrogen’), and renewable energy sources (‘green hydrogen’). Because oil was once thought of as “black gold,” Cemvita Factory now refers to their method of hydrogen extraction as “golden hydrogen.”
