In front of an audience of Government, Industry and Academic representatives, authors from leading UK universities presented their findings on The Role of Hydrogen and Fuel Cells in i) Delivering Energy Security for the UK, ii) The Future Energy Systems and iii) Creating Economic Impact for the UK.
Unbelievable as it may seem, it has been five years since the Hydrogen and Fuel Cells SUPERGEN was set up to help address the challenges facing the hydrogen and fuel cell sector in the UK. To celebrate this milestone, Imperial College will host an anniversary event on Friday 28th April to showcase half a decade of achievement in the H2FC research field. The H2FC Hub Management Board and other speakers will be presenting key research progress made in the area of hydrogen and fuel cells, illustrating the real world impacts of their work. The topics will range from developments in hydrogen production, storage and safety to SOFC and PEMFC advances, as well as the socioecomic and policy impact enabled by the Hub.
This event will also mark the launch of the ‘Five Years Impact Report’, which will be made available in hard-copy to attendees, as well as being put up online.
Tickets to the anniversary event are free, but spaces are limited so make sure you register your attendance in good time. To find out more details and to register your interest, go to https://www.eventbrite.co.uk/e/h2fc-supergen-five-year-anniversary-tickets-31933448805.
In a lighter piece of news today, fuel cell manufacturer Intelligent Energy announced a technology trial with London’s Metropolitan Police Force to supply them with hydrogen-powered Suzuki Burgman motorbikes. The scooters are equipped with 4kW air cooled fuel cells, making them lightweight but capable of meeting the police force’s safety and performance standards.
The clean bikes would be an important symbol for a city which is struggling to clean up its air pollution from traffic. More seriously, it shows an increasing institutional acceptance of hydrogen, helping to push the technology towards greater take-up.

Have a pair of Harvard scientists created the most powerful form of energy storage known to humanity?
Hydrogen hit the headlines this weekend, as Harvard researchers Ranga Dias and Isaac Silvera published a paper in Science claiming to have transmuted hydrogen into a solid metal (Observation of the Wigner-Huntington transition to metallic hydrogen). The pair first announced their discovery in October last year, but the full details have not been made available until now and the breakthrough is causing quite a stir.
Researchers have been attempting to produce solid metal hydrogen since it was first theorised in 1935 (E. Wigner, H. B. Huntington, On the possibility of a metallic modification of hydrogen. J. Chem. Phys. 3, 764–770 (1935)). Silva and Dias claim to have at last achieved success by slowly ratcheting up the pressure in a diamond vice to 495 GPa, 50% higher than the pressure in the centre of the Earth. Under these conditions their team observed the material changing from transparent to black to a shiny red; evidence enough for a metallic solid, according to their paper.
There is nothing new in submitting hydrogen to extreme pressure, but Silva and Dias believe they succeeded where others failed by cutting back on high-intensity laser spectroscopy, which can destroy the diamond or the hydrogen it is trained on. Instead they initially used a low intensity laser to avoid damaging the sample:
For fear of diamond failure due to laser illumination and possible heating of the black sample, we only measured the Raman active phonon at the very highest pressure of the experiment (495 GPa) after the sample transformed to metallic hydrogen and reflectance measurements had been made.
The potential for metallic hydrogen could be huge, as it is predicted to be a room-temperature superconductor which could revolutionise materials science. Its potential for storing energy could also be phenomenal. In a previous paper, Silvera suggested that hydrogen compressed to a metal could pack so much energy that it could be ‘The Most Powerful Rocket Fuel Yet to Exist’.
Much of this potential depends on whether or not metallic hydrogen is metastable and would retain its solid form once extreme pressure was released. As it stands, the paper offers no answer to this question. Having reached the critical pressure required to create their sample, the team have not yet modified their set-up for fear of destroying the sample. This has left a lot of questions unanswered – is it really a solid? Is it stable?
Big claims require big evidence, and the team has come in for criticism from several quarters for a lack of follow-through on their experiment. Science’s online announcement of the news gave rise to the kind of heated comments threads usually found on political news reports. Nonetheless, Silver and Dias stand by their results, saying that they wanted to announce the news before a second-round of tests potentially destroy their sample. ‘If people disagree, they should go to measure it and try to show that it’s different than what was claimed’, Silvera suggested.
Teams across the world will undoubtedly be throwing themselves into that very task, so we can expect more news on this subject as the year unfolds. If nothing else, the Harvard group have our attention.
The European Maritime Safety Agency released a technical study this week, reviewing 23 maritime Fuel Cell projects and assessing which technologies hold the most promise for improving shipping in the future. The report, which was conducted and prepared by DNV-GL, concluded that the three most promising hydrogen technologies were first Proton Exchange Membrane Fuel Cells (PEMFCs), followed by High Temperature PEMFCs and then Solid Oxide Fuel Cells (SOFCs).
Low-temperature PEMFCs won the gold for being a mature, safe and relatively cheap technology. High temperature PEMFCs were judged as more efficient but less safe, while SOFCs scored relatively poorly on cycling tolerance and cost.
However the report acknowledged that different technologies could complement each other, and that
“Smaller and medium applications may favour low and medium temperature technology, such as PEM and high temperature PEM. Larger applications which can more easily accommodate waste heat solutions, such as industrial and large maritime, are better for the high temperature solutions such as molten carbonate or solid oxide fuel cells.”
The full study, which also included a regulatory analysis and safety assessment for different fuel cell technologies on board ship, can be downloaded here.
The Scottish Hydrogen & Fuel Cell Association (SHFCA) has established a Memorandum of Understanding (MoU) with the corresponding trade association in the Spanish region of Aragon: the Aragon Hydrogen Foundation (FHA). A reciprocal trade mission with Aragon is now being planned, for the purpose of forging better links and nurturing trade and technology partnership opportunities. The date for this mission is February 2017, travelling out on Wednesday 15th February for a series of meetings and activities on Thursday 16th and Friday 17th February 2017 in and near Zaragoza, the principal city of Aragon. The mission is also likely to include a visit to the FHA facilities in Huesca, located about 30 miles from Zaragoza.
Arrangements are currently being put in place for this trade mission. It will be comprised of representatives from the Scottish Government and their agencies, together with a number of SHFCA members who have active interest in building trade and partnership links. However, there may still be a couple of places available, along with some financial support available towards meeting travel and accommodation costs.
If you or your organisation would like to take part in this mission to Aragon in February 2017 and have not already expressed interest, please email Nigel Holmes at email@example.com, with ‘SHFCA Member Interest in Aragon Mission’ included in the message header.
The Aragon Hydrogen Foundation (FHA) has a very similar number and composition of members as SHFCA, for information about FHA members and their regional strategy for hydrogen and fuel cells please take a look at the FHA website, which also includes other details and links to the Aragon 2016-2020 Masterplan: http://hidrogenoaragon.org/en/master-plan/.

As the hydrogen industry takes its place on the world phase, a symbolic launch of new industry group The Hydrogen Council took place at Davos yesterday. The newly-formed council was the brainchild of the EU’s ‘Fuel Cells and Hydrogen Joint Undertaking’, and consists of Chairpeople and CEOs from 13 major companies with a commercial interest in hydrogen. The Council’s stated goal is to work together to accelerate investment in commercial fuel cell and hydrogen projects. The represented companies are:
- Air Liquide,
- Anglo American,
- BMW GROUP,
- Hyundai Motor,
- Royal Dutch Shell,
- The Linde Group,
Collectively this group represents over a trillion Euros in revenues and a combined workforce of 1.72 million people. It marks a serious push into the hydrogen sector, by serious players.
The Council plans to provide recommendations to policy makers, business people, international agencies and civil society to achieve their goals of commercialising hydrogen and keeping global warming to within 2 degrees above historical averages. After its first meeting at Davos, the Council released two statements for its co-Chairs: the CEO of Air Liquide and the Chairman of Toyota.
“The 2015 Paris Agreement to combat climate change is a significant step in the right direction but requires business action to be taken to make such a pledge a reality. The Hydrogen Council brings together some of the world’s leading industrial, automotive and energy companies with a clear ambition to explain why hydrogen emerges among the key solutions for the energy transition, in the mobility as well as in the power, industrial and residential sectors, and therefore requires the development of new strategies at a scale to support this. But we cannot do it alone. We need governments to back hydrogen with actions of their own – for example through large-scale infrastructure investment schemes. Our call today to world leaders is to commit to hydrogen so that together we can meet our shared climate ambitions and give further traction to the emerging Hydrogen ecosystem.”
- Benoît Potier, CEO, Air Liquide.
“The Hydrogen Council will exhibit responsible leadership in showcasing hydrogen technology and its benefits to the world. It will seek collaboration, cooperation and understanding from governments, industry and most importantly, the public. At Toyota, we have always tried to play a leading role in environmental and technological advances in the automotive industry, including through the introduction of fuel cell vehicles. Moreover, we know that in addition to transportation, hydrogen has the potential to support our transition to a low carbon society across multiple industries and the entire value chain. The Hydrogen Council aims to actively encourage this transition.”
- Takeshi Uchiyamada, Chairman, Toyota.
To further mark their creation, the newly-formed council has released a report titled ‘How Hydrogen empowers the energy transition‘, now available for download in our Library page.
In a piece of good news to start off the year, researchers from Ulsan National Institute of Science and Technology in South Korea and Helmholtz-Zentrum Berlin in Germany have announced an efficiency breakthrough for their ‘artificial leaf’ project, which is really more like artificial seaweed. The research, published in Nature Communications, looks at mimicking aquatic plant photosynthesis to split water into its constituent elements.
The theory of solar water splitting is well understood, but finding the right photoelectrode materials has proved difficult. The Korean/German team favoured metal oxide semiconductors for their robustness and low cost, but needed to enhance their poor solar-to-hydrogen conversion rates. The team’s approach was to combine two established metal oxide photoanodes (BiVO4 and Fe2O3), which complement each other’s receptive properties on the solar spectrum. Unfortunately, when the materials were combined directly in a bilayer formation, their performance dropped markedly. Instead, the team came up with a ‘hetero-type dual photoelectrode (HDP)’, in which the materials were placed in parallel to form a tandem cell. BiVO4 as the front photoanode can utilise smaller wavelength photons, while longer wavelengths pass through to be collected by the Fe2O3 layer.
Interestingly, the idea mimics the behaviour of seaweed colonies and marine algae, which have evolved to layer themselves in different coloured bands at different depths in the sea. Green seaweed floats in the shallows and is receptive to red light, while the deeper-penetrating blue light is picked up by red weed. A single seaweed colony can vary its colours selectively as it descends in depth, optimising its photosynthesis for each layer.
The tandem cell set a new performance benchmark for metal oxide photoanodes, and the team believe that the HDP concept could prove a route to practical solar hydrogen production. “We aim to achieve 10% enhanced light harvesting efficiency within three years,” said Professor Jae Sung Lee. “This technology will greatly contribute to the establishment of the renewable-energy-type hydrogen refueling station by supplying cheap fuel for hydrogen fuel cell vehicles.
