Gas Processing and Step 1  Production Filling Facility

Hydrogen Mining Fill Station Gas Fuel
S1 Port Airport h2 Fueling Facility Kit Step 1 Hub Secure Supplies.png

The Secure Supplies Step 1 production facility is located in close proximity to a renewable reources Hydro or Solar Wind or conventional frid production block power system. Gas is delivered by a low pressure pipeline or via a mobile Pipeline to a compression hub site with convenient access for the transportation of packaged gas to the user location.

The gas compression hub comprises drying, compression, and the Secure Supplies Step 1 fuel pack/storage module filling facilities which incorporate chilling and transfer systems. Gas is compressed from delivery  pressure typically using reciprocating compressors and is then further compressed with hydraulically powered gas boosters.

The gas is then chilled and directed into the High Density Compressed Gas fuel packs that are used either for installation on mine trucks for  fast fill refilling or as “swap and go” cassettes. In cases where Secure Supplies Step 1 is transported to the user location, specially designed transport skids are used.

The gas compression hub contains:

 

  1. Multiple gas compressor modules installed adjacent to the gas supply point.

  2. Each module contains:

    • Gas compressor

    • Engine-driven 3 phase electric motor

    • Radiator package

    • Interstage and heat exchangers

    • Post compressor heat exchanger

  3. Gas Booster modules installed to supply gas into the Step 1 S1  Cassettes or cylinders.       Each module contains:

    • Gas boosters which will operate at high pressure

    • Heat exchangers

    • Hydraulic power pack

    • Chillers

While the area required for a typical gas processing & Secure Supplies Step 1 S1  production facility is quite small, when allowing for the turning circle of transport vehicles approximately 1 acre of land area is required.

Mining Hydrogen Fill Station

Mine Truck Conversion

Hydrogen mining truck conversion

Secure Supplies  haul truck fuel packs utilize Secure Supplies Step 1 S1  proprietary gas cylinder filling technology to achieve energy densities approximately double that of conventional h2 storage systems, and approaching two thirds of the density of H2 without the operational complexity and cost of H2 cryogenic storage and handling.

 

This enables mine trucks to achieve high levels of  displacement whilst carrying sufficient fuel on board for a full work shift and not adversely affecting payload.

NOTE: Payload differentials vary from 1234 kgs heavier for a Liebherr T282C to 1287 kgs lighter for a Caterpillar 797F according to make/model of the mine truck.

 

Comparison assumes standard diesel configuration with full fuel verses dual fuel configuration with full fuel.

Key elements of truck chassis conversion:

  1. Customised wiring looms to accommodate the new fuel system;

  2. Replacement of the existing fuel storage tank with a new  tank pod ;

  3. Replacement of the existing hydraulic tank with a new hydraulic tank should this be required;

  4. Installation of Secure Supplies  haul truck Secure Supplies Step 1 S1  Fuel Packs on both the driver’s side and offside of the truck adjacent to the Fuel Tanks and hydraulic tanks;

  5. All accompanying  fuel distribution lines and connection to engine bay;

  6. All associated and fully compliant gas/engine safety control systems.

Refuelling Options

hydrogen-fuel-pack.jpg

Refueling Station

The refueling of mobile mining equipment with Hydrogen fuel conversion can be either by high-flow direct injection from a Secure Supplies Dispenser (similar to a high-flow Diesel dispenser) directly into the Secure Supplies Step 1 S1 Fuel Packs on the machine, or by an autonomous “swap and go” refuelling system of Secure Supplies Cassettes.

Fuel Packs

The gas is chilled and directed into the Secure Supplies Step 1 S1 Fuel Packs that are either designed for installation on mine trucks for fixed fast fill refueling or as “swap and go” cassettes. In cases where Secure Supplies Step 1 S1is transported to the user location, specially designed gas transport crates may be used.

Secure Supplies Step 1 S1 Fuel Packs designed for in situ fast fill refuelling contain four cylinders. There are two fuel packs, one mounted on either side of the truck. The drivers’ side pack is installed adjacent to a slimline diesel tank and the off side pack is adjacent to the corresponding hydraulic tank.

The autonomous “swap and go” Secure Supplies Step 1 S1Fuel Pack is a steel cradle containing two cassettes. Each cassette contains two cylinders.

 

There are two cassettes on each side of the truck, contained in the steel cradles (i.e. a total of eight cylinders on the truck).

The drivers’ side cradle is adjacent to the slimline diesel tank and the off side cradle is adjacent to the hydraulic tank.

“Swap and Go” Quick Exchange System

Where the “swap and go” system is used, cassettes are filled with gas and stored on a rack until required to refuel the machine.

 

The cassette rack is located each side of the re-fuelling lane along with an autonomous cassette handling robot.

Robots are sourced from global manufacturers such as Kuka.

 

These robots are similar to those commonly used in a wide variety of harsh, heavy duty industrial applications around the world. Each robot is located on a track specifically designed for the mine refuelling site.

Each cassette is allocated a unique identification (ID) number via the use of RFID (Radio Frequency Identification Device). An RFID reader is located on each side of the refilling bay to enable empty cassettes to be detected and allocated for refuelling.

 

Laser technology, designed to operate in harsh mine site conditions, is used to guide the positioning of the robot in relation to the machine being refueled. The cassettes are stored in either a one or two story rack depending on truck fleet.

The autonomous “swap and go” refueling station will be located in a position that is protected from the machine by earthen berms or such other means required by the local mine SSE (Senior Site Executive).

An additional smaller robot is installed on the driver’s side to refill the diesel tank autonomously.

The Cylinders

Secure Supplies Step 1 S1 source Type  V Carbon Fibre Composite  H2 700 bar  cylinders 

Secure Supplies Step 1 S1 cylinders have been purpose designed and sized specifically for each application. Secure Supplies Step 1 S1 mine truck fuel packs are designed around available space on each make and model of mine truck. Larger cylinders are used for gas transport crates or gas storage modules.

Type  V Composite H2 Cylinders have evolved over several decades to become the pre-eminent choice for Secure Supplies Step 1 S1 fuel tanks on vehicles.

 

This dominance has now extended to the hydrogen fuelled vehicle industry. High pressure rating, light weight, robustness and life cycle are all features that have supported this evolution.

Type V H2 Composite cylinders comprise three fundamental components:

  1. a cylindrical HDPE ( carbon plastic) liner with domed ends that contains the gas;

  2. metallic boss ends that fit onto the domed ends; and

  3. a carbon fibre filament wrap that is wound over the liner with a resin coating on the carbon fibres.

  4. The carbon fibre wind pattern is proprietary to the manufacturer but is always wound helically around the liner in a criss-cross pattern that results in an extremely tough mesh of carbon fiber's glued in place by the resin. Secure Supplies Step 1 S1 also include a thin fibreglass outer layer to protect the carbon fibre surface

Certification Testing for Type V H2  Cylinders

The dominant codes regulating the fabrication of Type H2 V composite cylinders  are followed and certified to 700 bar DOT.

There are a total of thirteen prescriptive tests detailed in H2 Hydrogen Certifications for TypeV composite cylinders which includes a burst, fire, drop and ballistic test. All production cylinders must be designed to a minimum burst pressure of 2.25 times service pressure therefore a 10% margin is added to the 2.25 times to provide for deviations during cylinder production runs.

 

The 700 barg service pressure cylinders used by Secure Supplies Step 1 S1 are required to meet a minimum burst pressure of 12,500 psig during certification testing.

XCMG

builds “world’s largest” 400 t XDE440 mining truck for Zijin Mining and China Minmetals

Rolling off its production line today was the 400 t (metric) class diesel-electric AC drive XDE440 mining truck, claimed as the world’s largest by Xuzhou-headquartered Chinese construction and mining equipment giant XCMG. XCMG stated: “The XDE440, the world’s largest rear-drive rigid mining car, has rolled off the production line. This is not only an important milestone in the development of XCMG’s mining equipment industry, but also an important breakthrough in high-end mining equipment in China and the world.” It added that the truck is aimed at the “global high-end mining market” such as operations in South America, North America and Australia, citing a potential availability of over 95% and annual working hours of 7,300 hours.

The title of largest mining truck has already been claimed several years back by BELAZ with its 450 t 75710 but this is undoubtedly a new addition to the super ultra class mining truck world.

The company says the XDE440 is being delivered in batches to Chinese mining major Zijin Mining for its Serbia Zijin copper mines in Serbia (which includes three open pits), furthering the long-term strategic cooperation between the two companies. “We will keep pursuing an intelligent, high-end, green mining solution to level up our customer experience and maximise our customer value,” said Lu Chuan, President of XCMG at the launch event. XCMG’s mining equipment offer now includes 70-700 t mining excavators, 30-440 t mining dump trucks, 100-6,000 t/h crushing and screening machinery and 350 hp to 550 hp graders.

Zijin owns some of the world’s most important mines, particularly in copper and gold, from Julong Copper in Tibet, China, to a 39.6% interest in Kamoa-Kakula in DRC (45.04% including indirect holdings in Ivanhoe), Kolwezi copper mine, also in DRC, Buritica gold mine in Colombia, Cukari Peki copper mine in Serbia, plus numerous other operations in China. It has already applied a Chinese mining truck fleet in Serbia in the form of NHL NTE240 electric drive units.

XCMG said that the truck had also been developed for a second major mining customer, China Minmetals, the owner of MMG, which operates some of the world’s largest mines including Las Bambas copper mine in Peru, Dugald River zinc mine in Australia, Kinsevere copper mine in DRC and Rosebery base metals mine in Tasmania, Australia. “Minmetals and XCMG have a very deep and long-standing friendship. XCMG has strong engineering capabilities, reliable product quality and ultimate service throughout the lifecycle,” said Zhang Liang, Director of Resources Supply Chain at Minmetals Group, adding that the development of mines at home and abroad “is fully integrated with the advantages of XCMG’s advanced technology and equipment, and a new cooperation model has been established to help the high-quality development of the mines.”

“The XDE440 has a load capacity of 400 t, and is nearly three stories high, creating the world’s rear-drive rigid mining truck load record,” said XCMG Mining Machinery Project R&D Head Xie Heping, adding “in order to meet the demand of 400 t of load, we independently developed the world’s largest output torque and wheel reducer plus the world’s strongest wet disk brake.” XCMG also cited intelligent variable frequency traction, high torque hub drive, cab rollover protection and anti-fatigue design of large bearing components.

XCMG added that with the implementation of China’s national ‘3060 dual carbon’ strategy, “the mining and utilisation of China’s mineral resources is quietly undergoing a new round of adjustment. The green, high-end, large-scale and intelligent upgrading of mining construction equipment has become an inevitable trend.” The 3060 decarbonisation strategy is China’s commitment to hit peak emissions by 2030 at the latest and then achieve carbon neutrality by 2060.

Nine Chinese NHL NTE360A mining trucks of planned 28 so far assembled at Yancoal Mt Thorley Warkworth and in testing

Chinese mining truck leader Inner Mongolia North Hauler Joint Stock Co Ltd (NHL) based in Baotou, Inner Mongolia says that nine units of its NTE360A trucks have now been assembled in Australia at customer Yancoal’s Mt Thorley Warkworth (MTW) coal mine and are now in commissioning tests. Mt Thorley Warkworth is an integrated operation of two open cut mines located adjacent to each other, 15 km south-west of Singleton in the Hunter Valley region of New South Wales. Yancoal has ordered 28 360 ton (327 t) class NTE360A electric drive mining trucks in total, which are all equipped with Wabtec premium integrated AC electric drive systems and began shipping from the Port of Tianjin to Australia in May 2021.

This order is very significant globally as it represents one of the largest mining trucks made in China to have been exported out of China. In the past there have been a handful of Chinese OEM ultraclass truck units shipped in small numbers to Namibia and Australia for example, but no fleets on this scale, so this was truly a world first. NHL has also had success in Europe with exporting its large mining trucks, as it now has a fleet of 11 236t class NTE240 electric drive units running at Serbia Zijin Copper.

Wabtec told IM when the order was first announced that its Optimized Integrated Electric Drive Systems “deliver exceptional quality, customer value, and unparalleled technology. In both propulsion and retarding, they outperform other drives of equivalent payloads.” Bappa Banerjee, Wabtec’s General Manager of Mining Equipment added: “We are proud to partner with NHL and support their growth. These integrated electric drive systems will improve the performance of their mining trucks by reducing fuel costs and increasing reliability, giving their customers a distinct sustainable cost advantage over the service lifetime of their trucks.”

MTW an open cut mine, using a dragline truck and shovel method. Employees work in shifts to keep the mine operational 24 hours a day, seven days a week. After being washed and prepared for sale, the coal is loaded onto trains for transportation 90 km to the Port Waratah Coal Terminal in Newcastle where it is shipped to international customers.

OEM XCMG will soon start operating the largest fleet of high tonnage 
autonomous rigid mining trucks in the country. The first automation ready 
XDE240 220 t trucks recently started arriving at the Xiwan coal mine
in Shaanxi province, being developed by Shaanxi Shenyan Coal, part
of China’s coal mining giant China Energy Investment Corporation 
(CEIC, also known as CHN Energy, created from the merger of China
Guodian Corporation and Shenhua Group in 2017). The trucks will
be loaded by Taiyuan Heavy Industry (TYHI) WK-35 65 t payload 
electric rope shovels.

The fleet consists of 32 220 t XDE240 trucks, equipped with 
MTU 16V4000C23R 2,500 hp engines and Wabtec AC drives. 
IM understands that while XCMG has supplied the trucks with
an automation interface, the tender for a third party 
supplier to supply the unmanned technology was separately 
put out to bid by CEIC in September and was recently won by
CRRC-owned company Zhuzhou National Engineering Research 
Center of Converters. CRRC is a huge company best known for 
its rail equipment and technology but which also makes mining
equipment and supplies mining technology – through CRRC Yongji
it helped develop an FCEV mining truck with engine group Weichai 
while CRRC Datong started building its own electric drive CR240E mining haul trucks recently.
