LONDON — Plans to reduce the significant environmental effects of aviation took a step forward this week after Rolls-Royce and easyJet said they had carried out the ground test of a jet engine that used hydrogen produced from tidal and wind power.

In a statement this week, aerospace giant Rolls-Royce — not to be confused with Rolls-Royce Motor Cars, which is owned by BMW — described the news as a “milestone” and said it was “the world’s first run of a modern aero engine on hydrogen.”

The test, which was carried out at an outdoor site in the U.K., used a converted regional aircraft engine from London-listed Rolls-Royce.

The hydrogen came from facilities at the European Marine Energy Centre in Orkney, an archipelago in waters north of mainland Scotland. Since its inception in 2003, EMEC has become a major hub for the development of wave and tidal power.

Grant Shapps, the U.K.’s secretary of state for business, energy and industrial strategy, said the test was “an exciting demonstration of how business innovation can transform the way we live our lives.”

“This is a true British success story, with the hydrogen being used to power the jet engine today produced using tidal and wind energy from the Orkney Islands of Scotland,” Shapps added.

Hydrogen’s uses

Described by the International Energy Agency as a “versatile energy carrier,” hydrogen has a diverse range of applications and can be deployed in a wide range of industries.

It can be produced in a number of ways. One method includes electrolysis, with an electric current splitting water into oxygen and hydrogen.

If the electricity used in this process comes from a renewable source such as wind or tidal power, then some call it “green” or “renewable” hydrogen. Today, the majority of hydrogen production is based on fossil fuels.

Using hydrogen to power an internal combustion engine is different to hydrogen fuel cell technology, where hydrogen from a tank mixes with oxygen, generating electricity.

As the U.S. Department of Energy’s Alternative Fuels Data Center notes: “Fuel cell electric vehicles emit only water vapor and warm air, producing no tailpipe emissions.”

By contrast, hydrogen ICEs can produce other emissions. “Hydrogen engines release near zero, trace amounts of CO2 … but can produce nitrogen oxides, or NOx,” Cummins, an engine maker, says.

Industry’s aims

The environmental footprint of aviation is considerable, with the World Wildlife Fund describing it as “one of the fastest-growing sources of the greenhouse gas emissions driving global climate change.”

The WWF also says air travel is “currently the most carbon intensive activity an individual can make.”

Earlier this year, Guillaume Faury, the CEO of Airbus, told CNBC that aviation would “potentially face significant hurdles if we don’t manage to decarbonize at the right pace.”

Faury added that hydrogen planes represented the “ultimate solution” for the mid and long term.

While there is excitement in some quarters about hydrogen planes and their potential, a considerable amount of work needs to be done to commercialize the technology and roll it out on a large scale.

Speaking to CNBC last year, Ryanair CEO Michael O’Leary appeared cautious when it came to the outlook for new and emerging technologies in the sector.

“I think … we should be honest again,” he said. “Certainly, for the next decade … I don’t think you’re going to see any — there’s no technology out there that’s going to replace … carbon, jet aviation.”

“I don’t see the arrival of … hydrogen fuels, I don’t see the arrival of sustainable fuels, I don’t see the arrival of electric propulsion systems, certainly not before 2030,” O’Leary added.

Enwin Utilities adds $1 million Terex electric bucket truck to fleet [video]

The Windsor, Ontario utility says it’s driving towards a more sustainable future after adding a dozen new electric vehicles to its fleet – including a state-of-the-art, 55-foot Terex electric bucket truck.

Based on a Class 7 (33,000 lb. GVWR) International eMV Series BEV, the Terex EV takes the eMV’s 291 kWh battery and adds the Terex Optima 55-foot aerial device and HyPower SmartPTO system to create a fully electrified utility service vehicle that can do anything its diesel counterparts can do while offering better, safer working conditions for utility crews.

“We’ve got 12 EVs,” said Gary Rossi, president and CEO, Enwin Utilities. That number represents fully 10% of the utility’s entire vehicle fleet. “Our centerpiece is our electric 55-feet bucket truck. It’s very quiet,” continues Rossi. “So (the truck) allows us, our crews, to communicate better. It’s not as loud in the community when they’re doing repairs in someone’s backyard.”

That notion is echoed by Terex, itself. The company says its HyPower SmartPTO (power take off), which replaces a mechanical PTO, avoids a loud idling engine while reducing workers’ exposure to toxic exhaust fumes.

The utility company says the new electric bucket truck cost it almost $1 million Canadian – but while that might sound like a lot, Rossi says the price is similar to what a similarly-optioned ICE version of the bucket truck would cost.

“It’s all about building Windsor’s future and literally plugging into the battery factory down the road that is being constructed and showing that Windsor is a leader on this front,” says Drew Dilkens, Mayor of Windsor. “I don’t own an internal combustion engine vehicle,” adds Mayor Wilkins. “I only own two electric cars. My wife and I, we made the change starting in 2019 and I can’t see myself ever going back.”

Enwin says its commitment to clean energy extends beyond its vehicle fleet. The company recently unveiled a massive MW solar rooftop net metering facility at its Rhodes Drive headquarters with over 3,000 solar panels. The site, one of Canada’s largest solar installations, generates enough clean electricity to power 300 homes annually.

Damen sets a world record for most powerful electric tugboat

Built by Damen Shipyards and the first fully electric tugboat to be deployed in the Middle East, the new RSD-E Tug 2513 Bu Tinah put in its record-breaking performance took place at Khalifa Port during ADIPEC, the world’s largest energy conference.

The RSD-E Tug 2513 is based on the already efficient hull design of the standard, diesel-powered RSD Tug 2513, but its new, fully electric propulsion arrangement enables it to offer zero emissions operations in situations where oil or fuel leakage would be – let’s say especially bad.

But, while the “clean” aspect of all-electric operation is obvious, its Guinness World Record of performance shows that the Damen RSD-E Tug 2513 is up to whatever task its owners put to it.

“This Guinness World Record achievement demonstrates that the transition to alternative energy does not come at the cost of performance,” explains Maritime & Shipping Cluster, AD Ports Group, Captain Ammar Mubarak Al Shaiba. “We are very proud that the first electric tug in the Middle East is also making waves on a global level with this accolade and the fact that in parallel it is improving the sustainability of our operations alongside cost efficiencies in terms of overall fuel saving is extremely important. This vessel is now a key component of our Marine Services fleet and our electrification strategy.”

To earn its record, the the Damen RSD-E Tug 2513 Bu Tinah recorded an average high peak bollard pull of 78.2 tonnes (about 86 ‘Murican tons). The record-setting tugboat can undertake a minimum of two towage operation on a single charge, and can be recharged on a marine DC fast charger in just two hours.

Electrek’s Take

We’ve come a long way since 2021, when a 6MW electric tugboat was pulling about 50 tonnes of bollard weight. A nearly 50% jump in performance without a similar weight or mass gain is a sign of advancing technology – and we are here for it.

Trump picks Liberty Energy CEO and Oklo board member Chris Wright as Energy secretary

President-elect Donald Trump on Saturday selected Liberty Energy CEO Chris Wright to serve as the next energy secretary of the United States.

Liberty Energy is an oilfield services company headquartered in Denver with a $2.7 billion market capitalization. The company’s stock gained nearly 9% on Nov. 6 after Trump won the U.S. presidential election, but its shares have since pulled back.

Wright serves on the board of Oklo, a nuclear power startup backed by OpenAI CEO Sam Altman that is developing micro reactors.

Wright will also serve on Trump’s Council of National Energy, the president-elect said Saturday. The council will be led by Trump’s pick for Interior Secretary, North Dakota Gov. Doug Burgum.

Wright has denied that climate change presents a global crisis that needs to be addressed through a transition away from fossil fuels.

“There is no climate crisis and we’re not in the midst of an energy transition either,” Wright said in a video posted on his LinkedIn page last year. “Humans and all complex life on earth is simply impossible without carbon dioxide. Hence the term carbon pollution is outrageous.”

“There is no such thing as clean energy or dirty energy,” Wright said. “All energy sources have impacts on the world both positive and negative.”

Trump described Wright as a “leading technologist and entrepreneur in the energy sector.”

“He has worked in Nuclear, Solar, Geothermal, and Oil and Gas,” the president-elect said in a statement Saturday.

“Most significantly, Chris was one of the pioneers who helped launch the American Shale Revolution that fueled American Energy Independence, and transformed the Global Energy Markets and Geopolitics,” Trump said.

Trump has vowed to increase fossil fuel production to reduce energy costs, though analysts and some oil executives have said the president has little influence on oil and natural gas output in the U.S.

The U.S. has produced more crude oil than any other country in history, including Russia and Saudi Arabia, since 2018, according to the Energy Information Administration.
