Green hydrogen is touted to be one of the essential ingredients for the sustainable energy mix of the future. Yet, there’s an…invisible…yet big problem. Storage, transport, and operation is complicated and expensive, but what if we could create and store solid hydrogen for cheap? A start-up may have a solid technology that could speed up the energy transition. Spoiler: It’s so good it was banned!

With a minimalistic design and H-shaped front panel, the new mtu hydrogen fuel cell is a complete solution for power supply in the megawatt range that will be produced in series from 2025. This modern-looking module will in the future deliver a net power output of around 150 kW – sufficient to power approximately ten homes. It can also be connected together into scalable fuel cell power plants with outputs in the megawatt range – capable of providing clean backup power for large data centers.

The fuel cell module is the result of collaboration between Rolls-Royce and cellcentric, a joint venture company set up by Daimler Truck AG and Volvo Group AB earlier this year. It is based on cellcentric’s fuel cell modules that emit nothing other than water vapor. This will enable CO2-free, climate-neutral generation of emergency power for data centers.

“Electrical generators based on fuel cells represent the next leap forward in the energy transition, both for our customers and us,” said Andreas Schell, CEO of Rolls-Royce Power Systems. “That’s why we’re investing a three-digit million amount in R&D over the next few years, and we hope that this strong commitment will encourage governments and politicians to promote and support this pioneering, extremely climate-friendly technology. When they run on green hydrogen, meaning hydrogen made using renewable energy sources, fuel cells are climate-neutral. For this reason, and also because we’re simply convinced by fuel cell technology, we also want to look into how green hydrogen can be produced cost-effectively in the quantities we need.”

Beats road traffic any day.

As the world progresses towards electric vehicles and flying cars, a team of researchers from the Washington State University is working with ZEVA Aero, a Tacoma-based start up to test different components to create a single passenger, electric vertical takeoff and landing (eVTOL) aircraft.

It’s interesting to note that ZEVA Aero has already completed a functional prototype of a very futuristic looking eVTOL vehicle which has been assigned to use by first responders and emergency services before the general public. The prototype is capable of flying at 160 mph for up to 50 miles (80km). When it takes off from the ground, it hovers just like a helicopter and then tilts horizontally to fly more efficiently like a plane. This enables it to take advantage of the reduced drag and travel at faster speed as compared to other eVTOL vehicles.

What do the founders and leaders of Tesla, YouTube, and LinkedIn have in common? They all started their early careers at PayPal, the online payment company. This group of highly ambitious twenty and thirty-year-olds has been dubbed the “PayPal mafia” and once even dressed up as mafia members for the cover of Fortune magazine.

They went on to found or run some of the largest tech companies in the world. Elon Musk was absent the day of the shoot because of a scheduling conflict. This is by no means all of them. Peter Thiel estimates that the “mafia” is around 220 people.

Thiel is a famous start-up investor often referred to as the “don” of the PayPal mafia. PayPal began when Thiel and Max Levchin created software company Confinity as a way to transfer money through the once-popular Palm Pilot.

Twitter users said Mr. Musk should sell 10% of his Tesla shares after the billionaire chief executive polled them and pledged to abide by the outcome of the vote.

The noise barriers built in Switzerland can supply up to 101 gigawatt hours of solar electricity every year. The prerequisite is that all noise barriers are covered with solar installations, as far as this is possible and economical. This would be possible with a solar capacity of 111 megawatts. This is the result of a study commissioned by the Swiss Federal Council at the instigation of Bruno Storni, a member of parliament from the Swiss Social Democratic Party.

This potential is far below what is technically feasible. However, the authors of the study subtracted the potential that would hardly be economically feasible according to the current state of the art. In addition, they had to take into account site conditions such as shading of the walls or safety aspects.

101 gigawatt hours sounds a lot. But this is only 0.15 per cent of the usable solar potential on roofs and facades used for comparison in Switzerland. For the federal road administration Astra and the Swiss Federal Railways (SBB), however, it is nevertheless a major step towards climate neutrality. After all, solar installations on noise barriers near road tunnels alone cover eleven per cent of the potential on Astra’s total surfaces.

Tesla works on software… SpaceX gets hit with another delay… Elon Musk will pay taxes.

Cutting the price of CO₂ removal to under $100 per ton.

Reducing global carbon emissions can go a long way in reducing the impact of climate change, though it may not be enough.

In a bid to turn the tide around amid dire scientific predictions, the U.S. Department of Energy (DOE) announced ambitious new plans to accelerate the development of carbon capture technologies, a report from The Verge explains.
