Hyundai Motor Group and POSCO have formed a new hydrogen partnership, through which they will jointly develop hydrogen energy utilisation technologies.
Steam methane reformers consume natural gas to make grey hydrogen and they emit carbon dioxide as a consequence. In the long term, that can be mitigated with a transition to ‘green’ hydrogen production using electrolysers which can be fed with renewable electrical power or steam methane reformers fed with renewable biogas.
In the short-term retrofitting carbon capture to steam methane reformers (SMR), autothermal reformers (ATR) and gasification reactors to make so-called ‘blue hydrogen’ will make a big difference. Whether the carbon dioxide is captured and utilized (CCUS), or captured and stored (CCS) in permanent underground storage will in some way depend on the use-cases that are developed and commercialised.
On the 27th of January the European Parliament voted that blue hydrogen produced on SMRs from natural gas with CCS will be an acceptable bridge on the journey to full decarbonisation with green hydrogen. This must be one of the most important hydrogen policy decisions that has been taken recently. Surely this is the green light that is needed to get on with rapid and deep decarbonisation in many carbon-intensive sectors. It means that blue hydrogen will have political and market acceptance. The risk of stranded assets and bad investment decisions has been reduced.
Carbon capture is likely to add some cost. And it simultaneously represents a business opportunity. Much of the carbon dioxide that enters food and beverage value chains for freezing and carbonation applications is captured from ammonia production. Although carbon dioxide production generally far outstrips requirements in those industries.
Increasingly, carbon dioxide is also recovered from refinery SMRs. The advantage of having a carbon dioxide source from a refinery is that production is highly stable through the year because the demand for many fuels is not particularly seasonal. A guaranteed all year-round source of carbon dioxide can put the industrial gases supplier a highly reliable position with significant competitive advantage.
Bulk liquid carbon dioxide from a CCUS scheme can also be converted to dry ice for temperature-controlled supply chains. Dry ice gets daily attention at present for its role in the fight against the Coronavirus. Some vaccines must be shipped and stored at around minus 80 degrees Celsius and dry ice is ideal to maintain this low temperature.
The future of carbon dioxide utilisation will transform in the coming decades as decarbonisation deepens. Synthetic liquid fuels, known as e-fuels is one potential area. They are called e-fuels because electrical power is where the energy to create them comes from. Some electrolyser technologies such as the AEC and PEM can produce high quality hydrogen.
The solid oxide electrolyser can do that too, but it can go one step further. When they are fed with a mixture of steam and carbon dioxide, they can make syngas. And from syngas products such as petrol, diesel and jet fuel can be made using Fischer-Tropsch conversion.
Fischer-Tropsch conversion was used at scale by SASOL in South Africa several decades ago. Today, major GTL or gas to liquid projects such as Bintalu, Onyx, Escavos, Lu’an and Pearl all use the technology to convert syngas (which is produced on gasifiers or auto thermal reformers with the help of super-scale ASUs) to liquid fuels.
To decarbonise that process, the coal or natural gas feedstocks must be switched to steam and carbon dioxide, and the gasification unit or ATR must be replaced with a solid oxide electrolyser. It sounds easy, but the reality is that the change will take time and scale up is never as simple as it sounds. There is still lots of room for innovation from technology experts.
Another pathway to syngas from carbon dioxide is dry reforming of methane. Dry methane reforming uses carbon dioxide to react with the methane instead of steam. As with solid oxide electrolysis, the result is syngas which can be converted to liquid fuels.
Dry methane reforming is related to steam methane reforming, but it is different and more challenging. The process has been known about for decades. The barrier to commercialisation has been the difficulty in finding a catalyst that is able to convince the extremely stubborn carbon dioxide molecule to break apart and join the reaction to produce syngas without that same catalyst getting deactivated by carbon deposits. Innovation in this area will run and run. And it will be worth it.
Using carbon dioxide to make fuel that then burns to release carbon dioxide is an example of the circular economy. And the circular economy is simply nature in action – a man made carbon cycle.
Run by First Bus – Scotland’s largest bus operator – in a project led by Aberdeen City Council, the world’s first fleet of double decker hydrogen buses represent a major step forward in reducing climate change. This launch also underlines the Aberdeen’s role as the energy capital of Europe and shows its commitment to green energy as part of the city’s Net Zero Vision. In addition, plans are in place for Aberdeen to make its own hydrogen to power the buses, making it an even greener energy source for the local community.
The new £8.3million project is part of the European Union’s JIVE grant, which aims to aid commercialization of hydrogen buses through joint procurement between cities and funded by the Fuel Cells and Hydrogen Joint Undertaking (FCH JU). Manufactured by Wrightbus, the vehicles will be operated mainly on the Service 19 (Peterculter to Tillydrone).
“Aberdeen is one of Europe’s pioneering hydrogen cities and through the work of the city council, it has developed a cluster of hydrogen activity and the new double decker buses are a great addition to one of the largest and most varied fleets of hydrogen vehicles in Europe. They have even more advanced technology which pushes established hydrogen boundaries and will greatly assist us in tackling air pollution in the city,” said Aberdeen City Council Co-Leader Councilor Jenny Laing.
The new 60-seat double-deckers, which take less than 10 minutes to fully refuel, are set to transform the air of the city as they save one kilogram of CO2 with each kilometer they drive. The buses will also tackle more than just air pollution, as they are virtually silent helping to create quieter streets. While prototype hydrogen buses were designed and used previously, these double deckers are the first of their kind to go into commercial operation.
Andrew Jarvis, Managing Director at First Bus, said: “Today marks a significant milestone in our industry and the way that people choose to travel. First Bus serves thousands of customers in Aberdeen and we know that so many of our customers take the bus because they care about our planet and reducing their carbon footprint. We’re excited to now be able to offer them an even greener and quieter way of getting about the city.”
Wrightbus chairman, Jo Bamford, also commented: “Everyone at Wrightbus is incredibly proud to see the world’s first hydrogen double decker bus fleet in full service and carrying passengers around the streets of Aberdeen. It marks a pivotal moment in the city’s commitment to reaching net zero. We will see further Wrightbus hydrogen buses in locations across the UK, with fleets due to launch in Birmingham and London later this year. It’s vital that other towns and cities sit up and take note of their example.”
The buses have a bespoke hydrogen fuel system from Luxfer Gas Cylinders. The system for the 15-strong fleet features Luxfer’s G-Stor™ H2 cylinders. “The hydrogen economy is now taking off, but it’s an area we’ve worked in for three decades. Luxfer has pioneered hydrogen storage systems and valve technology, and we were brought into this project by Wrightbus in 2017 to help design how the hydrogen system could work to deliver the best range, in a cost effective solution,” added Mark Lawday, Director of Luxfer Gas Cylinders.

Kuwait Foreign Petroleum Exploration Company (KUFPEC) on Wednesday revealed details of its largest ever gas discovery.
According to a release, the company said the discovery, which was made through its wholly owned subsidiary KUFPEC Malaysia (SK-410B) Limited, was proven by the Lang Lebah-2 appraisal well in the SK-410B Block, located approximately 90 kilometres offshore Sarawak, Malaysia.
The appraisal drilling campaign followed the successful drilling of the first exploration well, Lang Lebah-1RDR2, in the SK 410B Block, in 2019.
A statement said: "KUFPEC Malaysia (SK-410B) Limited holds a 42.5 percent working interest under the PSC, with Petronas Carigali Sdn. Bhd. and PTTEP HK Offshore Limited (as operator) holding 15 percent and 42.5 percent working interests, respectively."
It added: "The appraisal drilling in Lang Lebah-2 was completed at a total depth of 4,320 metres, with over 600 metres of proven net gas pay."
The well was tested and flowed at 50 million cubic feet of gas-per-day with a significant amount of gas in place, indicating a substantially larger reservoir than the initial estimate.
"This successful world-class gas discovery is a testament to our steadfast efforts to maximise the value to our shareholder by exploring for hydrocarbons in highly prolific basins," said KUFPEC CEO Shaikh Nawaf Saud Al-Sabah.
"KUFPEC played a strong and active role in maturing the prospect that led to a giant discovery. I am proud of our team," he added.
KUFPEC is an international upstream company engaged in exploration, development and production of crude oil and natural gas outside Kuwait and is a wholly owned subsidiary of Kuwait Petroleum Corporation (KPC).
