Airbus has introduced its latest zero-emission eVTOL, designed to carry four people with a noise decibel range lower than a hairdryer when flying – which will radically cut into the noise pollution factor of a futuristic vision of eVTOLs buzzing around busy cities. Nearly five years in the making, this prototype targets a flight range of 50 miles (80 km) and a cruising speed of 75 mph (120 km/h).

Airbus’s latest prototype, the CityAirbus NextGen – unveiled at the opening of its new CityAirbus test center, which will be dedicated to testing systems for eVTOLs, in Donauwörth, Germany – is set to take its maiden flight this year.

The CityAirbus NextGen is an electric lift-plus-cruise vehicle designed for a variety of travel in major cities, including passenger transport, medical services, and ecotourism. Airbus says it will partner with operators and airlines to fly the model worldwide, with plans for it to take flight in Italy, Germany, Norway, and Japan, as well as regions in Latin America.

While at first, the CityAirbus will be flown by a pilot, it’s equipped with an operational automated flight mode that could enable future autonomous flying.

The aircraft, which can reach cruising speeds of 65 knots (about 75 mph) weighs two tons and has a 40-foot wingspan – so it’s by no means a tiny aircraft. It has a V-shaped tail, fixed wings, and a distributed electric propulsion system, with 16 electric power units and eight electric propellers. Back when Airbus introduced the NextGen design in 2021, it promised that these features keep sound levels to below 65 A-weighted decibels (dBA) during fly-over and below 70 dBA during landing – so that’s about the sound of a hairdryer or vacuum cleaner at landing, even less in flight. Perhaps closer to people talking loudly. Of course, Joby Aviation has its own air taxi that is 45.2 dBA when flying overheard, which it says is quieter than a typical conversation.

Electrek’s Take

Airbus is among many companies working on an electric aviation future, including US’s privately held Beta with its sleek CX300, a plane with a 50-foot wingspan, as well as establish players like Boeing and Embraer. In California, the aforementioned Joby Aviation and Archer Aviation, backed by companies like Toyota, Stellantis, and Delta and United Airlines,  are both developing battery-powered eVTOLs like Airbus’s. Since today’s batteries can support limited range and weight, these aircraft, for now at least, are designed to just carry a few passengers for short distances, putting their usefulness in competition with helicopters or even trucks for cargo. Of course the costs of producing these aircraft are astronomical to start, so we can just expect a few well-heeled passengers to be ferried around, or for critical services like medical evacuations on the immediate horizon, with the promise of a broader future on the horizon.

Then again, some companies have stopped gambling on an electric aviation future altogether and have turned their focus to low-carbon fuels.

‘This is a unique time’: ARK Invest’s chief futurist tackles tech innovation from AI to robotics

Private lives – why hot tech is shying away from IPOs

ARK Invest’s chief futurist lists five groups that should give tech investors an edge.

According to Brett Winton, robotics, artificial intelligence, multi-omics sequencing, public blockchain and energy storage are key areas because they’re all entering the marketplace at the same time.

“We believe that this is a unique time in technological economic history,” he told CNBC’s “ETF Edge” this week.

Winton collaborates with ARK Invest CEO Cathie Wood to maintain the ARK Venture Fund (ARKVX), which allows investors to buy into the private technology space.

According to the firm’s website, the goal of the fund is to make venture capital offerings of innovative spaces in the market accessible to individual investors. As of April 10, it shows the fund’s top holdings include Epic Games, known for online video game Fortnite, and biotech companies Freenome and Relation Therapeutics.

“Our emphasis is that we are investing in innovation over the long term and going to support management teams,” said Winton.

He contends it’s a strategy that’s often not prioritized.

“That’s a real challenge a lot of public market investors don’t have that long-term view,” Winton added.

The ARK Venture Fund is down more than 7% so far this year. However, it’s up almost 39% percent over the past 52-weeks.

World’s first hydrogen station for commercial trucks opens – is it too late?

World's first hydrogen station for commercial trucks opens – is it too late?

FirstElement Fuels has opened the world’s first large-scale hydrogen fueling station for heavy-duty commercial trucks just outside the Port of Oakland.

FirstElement is calling their new filling station, which opened to the public this week for tours and demonstrations, the first of its kind. Located near the Port of Oakland, the company claims its hydrogen pumps can “fill” a truck’s hydrogen tanks in as little as ten minutes, which works out (in their math) to as many as 200 trucks per day.

As for customers, the company says there are 30 Hyundai Xcient semi trucks using the fueling station currently, as well as a number of Nikola hydrogen fuel-cell-powered trucks.

A ceremony to mark the station’s opening was held Tuesday, and was attended by state officials including Liane Randolph, chair of the California Air Resources Board (CARB) and Tyson Eckerle, clean transportation advisor for Gov. Gavin Newsom’s business development office. Primary funding for the Oakland station was provided by CARB and the California Energy Commission.

Eckerle notes that the US federal government is handing out $8 billion to jump-start what it calls the “hydrogen economy,” and expects sufficient funding to build up to 60 more hydrogen truck stations like this one in California – which would, theoretically, be enough to serve 5,000 trucks and 1,000 buses.

All well and good, but …

What if it’s already too late for hydrogen?

MAN Trucks CEO, Alexander Vlaskamp, said it best when he said that it was “impossible” for hydrogen to effectively compete with BEVs.

He’s right – on a level playing field, there is absolutely no reason to believe hydrogen has any kind of future. But we don’t operate on a level playing field, and comments like Eckerle’s, along with an $8 billion federal budget and a number of supposedly genuine industry experts touting its usefulness as a fuel, mean we have to take hydrogen seriously (at least, for now).

Even so, it seems like the tide of public opinion is already starting to turn against hydrogen. Outlets that may never have questioned a manufacturer’s claims about a hydrogen-fueled vehicle a few years ago now seem more than willing to call those claims out. Here’s just one example:

Producing hydrogen itself can be very dirty. Most hydrogen produced today requires methane, which is a fossil fuel and a strong greenhouse gas contributor. The industry is working on production alternatives, including carbon capture and storage from the burning of methane, or quitting methane altogether to make green hydrogen, using an electrolyzer to split water’s hydrogen and oxygen.

Both alternatives are prohibitively expensive without government subsidies.

RUSS MITCHELL, AOL/Los Angeles TIMES.

So far, it’s not clear that FirstElement’s claims about either the sustainability of its hydrogen or the practicality of its filling station will convince many battery electric absolutists.

Take the company’s hydrogen production process as an example. FirstElement says that its supplier, Air Liquide in Las Vegas, uses natural gas as “feedstock” for its hydrogen. It buys biogas to blend with natural gas in order to create hydrogen – and that, because the gas used is more than 60% renewable, the hydrogen qualifies as “green.”

Additionally, the claim of 10 minute fast fills should come with an asterisk or two. That’s because FirstGreen is using new “cryopump” technology from Bosch Rexroth to allow for filling at 900 bar (15,000 psi). While that seems like more enough to push 100 kg into a tank in about ten minutes, cryogenically cooling hydrogen is an energy intensive technology that requires a lot of electricity to function properly. Electricity that it says will come from the stored hydrogen.

In fairness, however, Bosch has some ideas here to help station owners maximize the usefulness of all that electricity.

“Cold is like gold,” says Dave Hull, regional vice-president, Bosch Rexroth. “You’ve got all this cold energy. All my career I worked to get rid of heat. You can take that energy and run a whole station’s refrigerators for Rock Star energy drinks, or air conditioning. Bosh has a whole division of heat pumps and building technologies.”

Whether or not that added efficiency adds up to actual energy and cost savings, rather than a lifeline for the gas industry and tier 1 auto suppliers like Bosch however, remains to be seen. Meanwhile, hydrogen costs continue to rise.

Platts last assessed California’s retail hydrogen price at $33.48/kg Jan. 4, 2023, which is the weighted average hydrogen price offered at retail fueling stations across the state. The price has risen 112% from when Platts began the assessment in September 2021, according to S&P Global Commodity Insights data.

SP GLOBAL

Despite the high cost of hydrogen (“green” hydrogen is more expensive, still), Shane Stephens, one of FirstElement’s founders and its chief development officer, remains undeterred.

“We, at FirstElement Fuels, have a lot of confidence the market is coming,” says Stephens. “We see the regulations on the horizon, the OEMs and fleet owners are going to have to respond to that, especially when it comes to goods movement, and hydrogen and fuel cells are the best – if not only – solution that will work for many of those use cases.”

Electrek’s Take

As a light vehicle fuel – despite the efforts of Hyundai, Toyota, and (more recently) Honda – things aren’t going well for hydrogen. As a fuel for massive semi trucks and even bigger heavy equipment, however, it might stand a chance against current battery technology.

But battery tech isn’t stagnant, and lighter, better, faster charging battery news that used to come every year, and then every month, now seems to be coming every week – and I’d argue that you’d be foolish to assume batteries that are twice as energy dense at half the weight won’t be here well ahead of California’s 2035 ICE ban.

But that’s just me. You guys are smart. Head on down to the comments and let us know what you think.

Maritime Transport begins electrification of trucking fleet

One of the UK’s leading road and rail logistics companies, Maritime Transport, is making some big moves in a bid to electrify its trucking fleet – with fully 18 all-electric, three axle tractor units from Scania leading the charge.

As part of the UK’s Zero Emission HGV and Infrastructure Demonstrator (ZEHID) program, Maritime Transport has put 48 battery electric and hydrogen fuel cell-powered semi trucks on order, with the initial order of 18 big Scania trucks arriving first.

“This investment places us at the forefront of our industry’s transition to sustainable operations and we are excited to initiate this phase of our environmental strategy,” says Maritime Transport Deputy Chief Executive, Tom Williams. “Our active participation in ZEHID and pioneering initiatives like eFREIGHT 2030 over the next five years is set to yield vital insights for the government’s long-term infrastructure decisions to make road freight more sustainable and reduce greenhouse gas emissions. Acknowledging the variations in range and payload, we believe these vehicles will substantially contribute to our efforts in providing sustainable and efficient services to our customers, complementing our growing network of rail freight services and terminals.”

The new, three axle Scania semi trucks are rated for 42 tonnes, and offer of a range of 300-500 km (up to 310 miles), allowing them to serve Maritime Transport’s eight existing rail freight terminals from each of the major UK ports.

Maritime says the introduction of these trucks is a core component of the company’s environmental agenda, which will effectively lead to their moving more containerized product by rail with electrically-driven trucks on first and last-mile deliveries. The trucks are planned to begin arriving at Maritime’s ports later this year and into early ’20’25. High-powered EV charging stations will also be installed across the company’s network of 41 depots, terminals, and container storage sites.

Electrek’s Take

Electrifying everything at a container yard – from the biggest material handlers to smaller scissor and fork lifts – is no-brainer. In a contained, controlled environment with predictable routes and known loads, electrification is the most affordable and practical solution, and we can’t wait to see the data confirming that.
