Another Rolls-Royce and EasyJet announced hydrogen internal combustion engines for aircraft
Aerospace giant Rolls-Royce (not to be confused with BMW-owned Rolls-Royce Motor Cars) said on Tuesday that it has teamed up with EasyJet to develop and test hydrogen combustion engine technology for aircraft. The announcement follows Rolls-Royce’s announcement earlier this week that it will start testing hydrogen-powered aircraft engines.
London-based Rolls-Royce said in a statement that testing should begin this year. Both companies have a “common ambition to take technology to the air”. The goal of the collaboration, dubbed H2ZERO, “is to demonstrate that hydrogen can be used to power a range of aircraft from the mid-2030s,” Rolls-Royce said.
The firms will conduct “early concept ground tests” of a Rolls-Royce engine using hydrogen technology in the UK this year. This will be followed by a full scale ground test of the technology using a Pearl 15 jet engine in Mississippi.
“The technology resulting from this program can be used on aircraft the size of EasyJet, so we will also be making a multi-million dollar investment in this program,” said Johan Lundgren, CEO of EasyJet. “For large-scale decarburization, progress in the development of zero-emissions technology for narrow-body aircraft is critical.”
Using hydrogen to power an internal combustion engine is different from hydrogen fuel cell technology, where gas from a tank is mixed with oxygen to produce electricity. Fuel cell vehicles emit “only water vapor and warm air”. In contrast, hydrogen ICEs can produce other emissions. “Hydrogen engines emit almost zero trace amounts of CO2 … but can produce oxides of nitrogen or NOx,” says a spokesman for engine manufacturer Cummins.
Aviation’s environmental impact is significant, with the WWF describing it as “one of the fastest growing sources of greenhouse gas emissions causing global climate change”.
The WWF also states that air travel is “currently the most carbon-intensive human activity.”
LG Electronics has unveiled its own foldable device with a large flexible screen. It was a laptop called LG Gram Fold.
This is an expensive and powerful model; at first it will be sold only in LG’s native Korean market. For the LG Gram Fold, the manufacturer asks $3,730. However, it is noticeably cheaper than HP’s $5,000 flexible-screen laptop.
In addition, the first 200 customers who order it in Korea will be able to get the laptop for just under $3,000. Of course, it’s unclear whether this device will ever be released internationally, let alone how much it will cost.
Unlike other foldable PCs currently on the market, the LG Gram Fold is powered by a 13th Gen Intel Core processor (i5-1335U), while its HP counterpart uses 12th Gen processors.
Other characteristics include a 17-inch display with a resolution of 2560 x 1920 pixels; when folded, the user has access to a 12-inch screen with 1920 x 1280 pixels, 16 GB of LPDDR5 RAM and a 512 GB solid-state drive, and a 72 Wh battery. There are two USB Type-C ports, one of which supports Thunderbolt 4.
The Gram Fold comes with a Bluetooth keyboard that can be used separately from the laptop. Also included is a 65W charger and a stand case that protects the laptop and supports it when used on a desk.

The most powerful and most economical Haval Dargo 2 has gone on sale. 326 hp, consumption 1.85 l/100 km, lifetime warranty on the power plant and a camping mosquito lamp – for $23,000
Today in China, the Haval Big Dog (aka the second-generation Haval Dargo crossover) was officially presented as a plug-in hybrid. This is the most powerful version of the second Dargo, and it is also the most economical.
Externally, the car is no different from its regular gasoline counterparts, except for the logo: it is made on a blue background, while pure gasoline versions have a black background under the logo. The design of the second Dargo is made in the spirit of the first generation car, but it is impossible to confuse them, especially when looking at it in profile or from the rear.
Dimensions are 4705 x 1908 x 1780 mm, wheelbase is 2810 mm. The approach and departure angles are 24° and 30°, the minimum ground clearance is 200 mm (in China it is measured when the car is loaded). Among the interesting features is the presence of a 220 V socket with an output power of 3.3 kW for powering any external consumers and… a removable camping mosquito lamp, which will be appreciated by lovers of adventures and road trips.
The power plant is based on a 1.5-liter turbo engine. It works in conjunction with an electric motor and a 2-speed DHT transmission. The total power of the power plant elements is 326 hp, torque – 530 Nm. Consumption in hybrid operating mode is only 1.85 l/100 km (but with a discharged traction battery it will be three times more, the range on pure electricity is 105 km, and the full range of a fueled and charged SUV is more than 1000 km.
