United Kingdom

CCUS has economy-wide qualities which could be very valuable to delivering clean industrial growth. It could deliver tangible results in tackling some of the biggest challenges we face in decarbonising our economy contributing to industrial competitiveness and generating new economic opportunities – a key part of our modern Industrial Strategy.

Our vision is to become a global leader in CCUS unlocking the potential of the technology and securing the added value which it can bring to our industrial centres and businesses all across the UK.

Our ambition is that the UK should have the option to deploy CCUS at scale during the 2030s subject to the costs coming down sufficiently.

Our Industrial Strategy set out four Grand Challenges to put the UK at the forefront of the industries of the future. The Clean Growth Grand Challenge seeks to maximise the advantages for UK industry from the global shift to clean growth. CCUS can be an important part of achieving these objectives.

The House of Lords Science and Technology Committee will hear from officials research funders and leading research consortia about the UK’s strategy for research and development of batteries and fuel cells to help meet the net-zero target.



The Committee will question officials from government departments and research councils about the UK’s increased support for battery development and how the initiatives and funding will evolve. The Committee will compare the support given to fuel cell research and ask how this technology will be developed for applications such as heavy transport. For both technologies it will ask how training will be delivered to provide a skilled workforce.



The Committee will also hear from leaders of research consortia asking them about support for their research sectors and how this compares with countries leading the development of the technologies. The Committee will explore coordination between research into batteries fuel cells and wider strategies such as for hydrogen and whether research for transport can be transferred to applications in other sectors such as power grids and heating.

The increasing demand for energy and commodities has led to escalating greenhouse gas emissions the chief of which is represented by carbon dioxide (CO2). Blue hydrogen (H2) a lowcarbon hydrogen produced from natural gas with carbon capture technologies applied has been suggested as a possible alternative to fossil fuels in processes with hard-to-abate emission sources including refining chemical petrochemical and transport sectors. Due to the recent international directives aimed to combat climate change even existing hydrogen plants should be retrofitted with carbon capture units. To optimize the process economics of such retrofit it has been proposed to remove CO2 from the pressure swing adsorption (PSA) tail gas to exploit the relatively high CO2 concentration. This study aimed to design and numerically investigate a vacuum pressure swing adsorption (VPSA) process capable of capturing CO2 from the PSA tail gas of an industrial steam methane reforming (SMR)-based hydrogen plant using NaX zeolite adsorbent. The effect of operating conditions such as purge-to-feed ratio and desorption pressure were evaluated in relation to CO2 purity CO2 recovery bed productivity and specific energy consumption. We found that conventional cycle configurations namely a 2-bed 4-step Skarstrom cycle and a 2-bed 6-step modified Skarstrom cycle with pressure equalization were able to concentrate CO2 to a purity greater than 95% with a CO2 recovery of around 77% and 90% respectively. Therefore the latter configuration could serve as an efficient process to decarbonize existing hydrogen plants and produce blue H2.

The rare earth metals have been identified by the European Union and the United States as being at greatest supply risk of all the materials for clean energy technologies. Of particular concern are neodymium and dysprosium both of which are employed in neodymium–iron–boron based magnets. Recycling of magnets based on these materials and contained within obsolete electronic equipment could provide an additional and secure supply. In the present work hydrogen has been employed as a processing agent to decrepitate sintered neodymium–iron–boron based magnets contained within hard disk drives into a demagnetised hydrogenated powder. This powder was then extracted mechanically from the devices with an extraction efficiency of 90 ± 5% and processed further using a combination of sieves and ball bearings to produce a powder containing <330 parts per million of nickel contamination. It is then possible for the extracted powder to be re-processed in a number of ways namely directly by blending and re-sintering to form fully dense magnets by Hydrogenation Disproportionation Desorption Recombination processing to produce an anisotropic coercive powder suitable for bonded magnets by re-melting; or by chemical extraction of the rare earth elements from the alloy. For example it was shown that by the re-sintering route it was possible to recover >90% of the magnetic properties of the starting material with significantly less energy than that employed in primary magnet production. The particular route used will depend upon the magnetic properties required the level of contamination of the extracted material and the compositional variation of the feedstock. The various possibilities have been summarised in a flow diagram.

In this podcast David Ledesma talks with Rahmat Poudineh and Martin Palovic about their paper on integrating hydrogen into the European energy transfer infrastructure landscape. As hydrogen is expected to play an important role in European plans towards climate neutrality adequate hydrogen transport (and storage) infrastructure needs to be established. However hydrogen transport infrastructures are costly and have a long lead time. Furthermore hydrogen can be transported via a variety of means: it can be transported as a gas via pipelines or liquid via road rail and sea or even converted to derivatives such as ammonia or methanol for long distance transportation. It is also possible to transfer electrical energy instead of hydrogen and produce hydrogen in a decentralized way. From a system perspective all these infrastructures represent elements of a grand hydrogen ‘polygrid’ that will be the backbone of the future decarbonized energy system. This raises the fundamental question of how to prevent inefficiency and infrastructure redundancy across different modes of hydrogen transport. The task is made more challenging by technological uncertainty the unpredictability of future supply and demand for hydrogen network externality effects and investment irreversibility of grid-based infrastructures. In this podcast we discuss three possible coordination approaches to optimise future cross-sectoral investment into hydrogen transport infrastructure and highlight their strengths and shortcomings.

The increasing demand for hydrogen has made it a promising alternative for decarbonizing industries and reducing CO2 emissions. Although mainly produced through the gray pathway the integration of carbon capture and storage (CCS) reduces the CO2 emissions. This study presents a sustainability method that uses flare gas for hydrogen production through steam methane reforming (SMR) with CCS supported by a techno-economic analysis. Data Envelopment Analysis (DEA) was used to evaluate the oil company’s efficiency and inverse DEA/sensitivity analysis identified maximum flare gas reduction which was modeled in Aspen HYSYS V14. Subsequently an economic evaluation was performed to determine the levelized cost of hydrogen (LCOH) and the cost–benefit ratio (CBR) for Nigeria. The CBR results were 2.15 (payback of 4.11 years with carbon credit) and 1.96 (payback of 4.55 years without carbon credit) indicating strong economic feasibility. These findings promote a practical approach for waste reduction aiding Nigeria’s transition to a circular low-carbon economy and demonstrate a positive relationship between lean and green strategies in the petroleum sector.

Current commercially available options for decarbonisation of road transport are battery electric vehicles or hydrogen fuel cell electric vehicles. BEVs are increasingly deployed while hydrogen is in its infancy. We examine the infrastructure necessary to support hydrogen fuelling to various degrees of market penetration. Scotland makes a good exemplar of transport transition with a world leading Net-Zero ambition and proven pathways for generating ample renewable energy. We identified essential elements of the new transport systems and the associated capital expenditure. We developed nine scenarios based on the pace of change and the ultimate market share of hydrogen and constructed a model to analyse their infrastructure requirements. This is a multi-period model incorporating Monte Carlo and Markov Chain elements. A “no-regrets” initial action is rapid deployment of enough hydrogen infrastructure to facilitate the early years of a scenario where diesel fuel becomes replaced with hydrogen. Even in a lower demand scenario of only large and heavy goods vehicles using hydrogen the same infrastructure would be required within a further two years. Subsequent investment in infrastructure could be considered in the light of this initial development.

The reduction of harmful emissions from the international shipping sector is necessary. On-board energy demand can be categorised as either: propulsion or auxiliary services. Auxiliary services contribute a significant proportion of energy demand with major loads including: compressors pumps and HVAC (heating ventilation and air-conditioning). Typically this demand is met using the same fuel source as the main propulsion (i.e. fossil fuels). This study has analysed whether emissions from large scale ships could feasibly be reduced by meeting auxiliary demand by installing a hydrogen fuel cell using data from an LNG tanker to develop a case study. Simulations have shown that for a capacity of 10 x 40ft containers of compressed hydrogen the optimal fuel cell size would be 3 MW and this could save 10600 MWh of fossil fuel use equivalent to 2343 t of CO2. Hence this could potentially decarbonise a significant proportion of shipping energy demand. Although there are some notable technical and commercial considerations such as fuel cell lifetime and capital expenditure requirements. Results imply that if auxiliary loads could be managed to avoid peaks in demand this could further increase the effectiveness of this concept.

In this Podcast David Ledesma discusses with Stephen Craen Visiting Research Fellow OIES the challenges facing the financing of future hydrogen projects as it is expected that a substantial amount of capital will need to be invested in green hydrogen production to meet the 2050 net zero targets. Based around an ‘Archetype’ world scale hydrogen export project where 1 GW solar power is used to make green hydrogen which is converted to 250000 tpa green ammonia for export with a capital cost in the region of USD 2 billion the podcast discusses how ‘efficient financing’ can make an important contribution to minimising cost and making projects cost competitive. Stephen Craen argues that lenders and investors will look to precedents when assessing the nascent green hydrogen sector and the foremost will be LNG and offshore wind which both represent large-scale technically complex projects. Commercial structures of the green hydrogen business are expected to borrow concepts from offshore wind projects particularly in relation to price but also from LNG where this is relevant such as take-or-pay contracts. In this podcast we discuss the key issues that will need to be addressed to make a green hydrogen export project bankable concluding that commercial debt from either commercial banks or project bonds can help create competition.

The steel sector currently accounts for 7% of global energy-related CO2 emissions and requires deep reform to disconnect from fossil fuels. Here we investigate the market competitiveness of one of the widely considered decarbonisation routes for primary steel production: green hydrogen-based direct reduction of iron ore followed by electric arc furnace steelmaking. Through analysing over 300 locations by combined use of optimisation and machine learning we show that competitive renewables-based steel production is located nearby the tropic of Capricorn and Cancer characterised by superior solar with supplementary onshore wind in addition to high-quality iron ore and low steelworker wages. If coking coal prices remain high fossil-free steel could attain competitiveness in favourable locations from 2030 further improving towards 2050. Large-scale implementation requires attention to the abundance of suitable iron ore and other resources such as land and water technical challenges associated with direct reduction and future supply chain configuration.
