Hydrogen gas is being heralded as the next big thing in the race to come up with new greener energy sources. Now, researchers at the Irish nanoscience institute CRANN say they have developed a new method of splitting water into hydrogen and oxygen more sustainably via water electrolysis.
The researchers, who are based at the Science Foundation Ireland-funded nanoscience institute CRANN, which is situated on the Trinity College Dublin (TCD) campus, are claiming their discovery will have a “significant” impact in the worldwide race to cheaply and efficiently produce hydrogen gas.
In scientific and clean-tech circles, hydrogen gas has been hailed as one of the main clean-energy sources of the future.
Prof Mike Lyons, a principal investigator at CRANN and TCD’s School of Chemistry, has worked with his research team to develop what they are calling new inexpensive materials based on iron and nickel oxide to split water into its components hydrogen and oxygen – a method known as water electrolysis.
Apparently, these materials from iron and nickel oxide are much cheaper, more readily available and more efficient than those used in current electrolysis methods.
Hydrogen gas has been pinpointed as one of the most innovative and greener alternative energy sources of the future. Its production using steam reforming of natural gas is still relatively difficult and unsustainable, however.
In contrast, hydrogen generation by water electrolysis could pave the way for a reliable, environmentally friendly method of large-scale production.

The researchers at CRANN involved in the water-splitting project believe their methods are the first inexpensive and efficient methods of water electrolysis to be identified worldwide.
Their research has already triggered international interest and recently received ‘Hot Article Status’ in the chemistry journal Physical Chemistry Chemical Physics (PCCP). Hot Article Status, it seems, is given to articles of high impact and high quality.
Prof John Boland, director of CRANN, said the results of nanoscience research is paving the way for revamping a range of industries – from medicine, to technology to energy production.
“Whether it is in lightweight coatings for wind turbines, or new sensors for solar panels, our methods continue to assist in the move to sustainable, alternative and clean energy supply,” he said.
A world first?
Boland believes Lyons and his research team’s method of splitting water is a “world first”.
“It truly has the potential to revolutionise the production of hydrogen gas and bring it one step closer as a realistic energy alternative,” he said.
Lyons has received funding to the value of almost €800,000 from SFI for this research.
“With my team of researchers, we are consistently striving to use well-known research methods to deliver unprecedented results,” he said today.
This method of water electrolysis, explained Lyons, takes the simplest of materials – nickel and iron – and uses them to “ground-breaking” effect.
“Hydrogen is the next clean-energy source and CRANN is leading the international race to find its best method of production,” added Lyons.
As well as his work at CRANN, Lyons also leads the Trinity Electrochemical Energy Conversion and Electrocatalysis Group. He has published two books and more than 110 papers, and has a h-index of 25, which demonstrates the worldwide impact of his research.
Minute knots and chains have industrial and medical uses
Scientists have devised a new molecular technique, inspired by Celtic Knots and trees, which could be used in the treatment of multiple diseases.
Researchers at the Network of Excellence for Functional Biomaterials (NFB) in NUI Galway have discovered a new process that could be used in the industrial and medical fields.
“Polymerisation is the adding together of many smaller units,” says research assistant to the project’s leader Doctor Wenxin Wang, Ben Newland. “It is one of the most important processes in industrial manufacturing.”
The new process gives scientists a “simple method to produce large quantities of well-defined material”, which could be used in diagnostic, therapeutic and imaging processes in the body Newland says.
The Celtic Knots are an example of the new technique. A single chain is linked repeatedly, wrapping around itself, creating a very dense structure. These structures are needed to carry DNA, and can be used in gene therapies or new forms of drug treatment.
The tree-inspired hyper-branching, could also be used to produce hydrogels. These hydrogels are composed of a soft jelly, in which cells can be suspended. This could be used to deliver cells to damaged areas of the body, Newland said. In conditions like Epidermolysis Bullosa, where connective tissues of the skin tear, this hydrogel would be applied to the wound, using the Celtic Knot as a skin adhesive. The cells could then repair the broken tissue.
As a topical ointment, it might be approved sooner by the FDA, Newland says. Regarding its use on people, Newland concedes this would be a big step, but estimates we could see this within 5 to 10 years.
Newland believes the polymerisation technique itself “will become widespread”, due to its numerous industrial applications in the manufacturing of elastics or higher strength plastic, for example.
Dr Wang, who has pursued this technology since 2007, notes that “although these are early steps, we are looking forward to seeing the future realisation of these structures in a wide range of applications.”
The NFB is involved in international collaborations with biomaterial groups investigating the use of biomaterials in the body.
NANOSCIENCE IS THE the study of materials on the nanoscale, or one million times smaller than a grain of salt. By studying materials at their most basic and modifying the ‘building blocks’ from which they are made, nanoscience researchers can vastly improve the properties of those materials. Plastics can become extremely thin, but incredibly strong. Metals can become thoroughly flexible and malleable, but hugely conductive and light. That process of change opens up a world of possibilities for manufacturing in technology, medicine, energy, pharmaceuticals, transport, bioengineering and more.
CRANN (the Centre for Research on Adaptive Nanostructure and Nanodevices) is Ireland’s leading nanoscience institute, funded by Science Foundation Ireland and based at Trinity College Dublin. In the past ten years, our researchers have leveraged State funding to bring in over €50 million of non-Exchequer investment from international and European sources and have filed over 50 patent applications.
Today, CRANN celebrates its 10th anniversary.
This research is crucial to the economy
It was in 2003 that the then Government decided to prioritise nanoscience research, and established CRANN, as part of Science Foundation Ireland’s CSET (Centre for Science Engineering and Technology) programme. Since then, the Centre has grown from having just six researchers to employing over 300 and from working with 4 companies to over 100 companies, in Ireland and internationally. If Government is looking for an example of an ambitious policy decision that is now paying dividends for the Irish economy, they do not need to look any further than CRANN.
Ranked sixth in the world for nanoscience research and eighth for materials science research, Ireland is now recognised as a leading nanoscience nation. With over 90 per cent of the world’s medical multinationals and 70 per cent of the world’s technology multinationals having a base in Ireland, our national research credentials are extremely attractive, and crucial to the economy.
It is estimated that nanoscience is linked to €15 billion, or 10 per cent, of Ireland’s annual exports and supports 250,000 jobs nationwide. The Government has targeted 20,000 more manufacturing jobs in Ireland by 2016 and undoubtedly, Ireland’s leading nanoscience research can help to create those jobs.
As part of CRANN’s 10-year celebrations, the team created the world’s smallest birthday cake – measure 2,000 times smaller than the full stop at the end of this sentence.
Ireland is now experiencing a ‘brain – gain’
Irish researchers are awarded the highest number of European Research Council Starting grants for nanoscience research in the European Union. Following the Euroscience Open Forum in 2012, Dublin has again been chosen to host the EuroNanoForum, Europe’s largest nanoscience event in June this year, an event which will attract 12,000 delegates. In addition, Ireland is now experiencing a ‘brain – gain’, attracting researchers from abroad, to complement our indigenous research base.
Ireland’s nanoscience credentials are strong and they are growing.
At CRANN, we are working with over 100 companies in Ireland and internationally, using our research expertise to help those companies develop novel products and solutions. For example, over the past decade, we have partnered with Intel, working on innovative methods to constantly improve their technologies. We work with Sab Miller, a brewing and beverage company, helping them to improve their packaging to extend the life-span of their products. These partnerships deliver significant mutual benefit for both CRANN and for our partners and will continue to do so for the next decade and beyond.
Smaller, better, faster, stronger
Nanoscience is changing the face of manufacturing, leading to smaller, smarter, more durable and more efficient products and it is a strong linkage between academia and business that is driving that progress. It is nanoscience that is allowing smart devices to become smaller and smaller, yet to store more information. It is nanoscience that is leading to smaller, more sophisticated medical devices like heart stents, with greater lifespans.
Nanoscience is leading to lighter, yet stronger aeroplanes that consume less fuel. It is leading to technological developments like computers with advanced memory and facial recognition, laptops and smart-phones that can be rolled up like newspapers, bathroom mirrors and windows that can become television screens. It could lead to sensors that detect diseases from a person’s breath, or to coatings for ships and tankers that cannot rust.
These are advances that are happening now and they are happening worldwide. By investing in nanoscience; our health, our environment and our communications will be vastly improved.
Nanoscience is the future
Europe has recognised this. This year, the European Commission has invested €1 billion in the Graphene Flagship Project, identifying graphene, one layer of graphite found in pencil lead, as a ‘product of the future’. Ireland has a leading role in that project. The Irish Government has recognised this too, protecting science investment, even in difficult economic times. Science Foundation Ireland must be commended for its commitment and vision, in recognising that protecting scientific funding can also protect and grow the Irish economy.
Ten years ago, the global market for nano-enabled materials was €420 million. In 2015, it will be $2.5 trillion. Nanoscience is the future. Ireland is very much part of it.
I look forward to another ten years of success.

Health Innovation Hub launches to help healthcare companies create solutions faster – Irish Innovation News – Siliconrepublic.com
Michael Fitzgerald, CEO of Abtran, one of the companies participating in the Health Innovation Hub demonstrator project
A new healthcare project has launched in Cork today to bring together six healthcare companies with the health system and academia in order to help such companies move faster on developing products and services.
The Minister for Jobs, Enterprise and Innovation Richard Bruton, TD, and the Minister for Health Dr James Reilly, TD, launched the new Health Innovation Hub project at University College Cork (UCC) today.
The project, which has been based on international models, such as the North Carolina Research Triangle, is aiming to progress healthcare technologies.
The idea is to help healthcare companies deliver commercial products and services more quickly by giving them access to the health service in order to test products in a real-life environment. Another aim of the project is to allow the health service to become more efficient by enabling the HSE and hospitals to engage and participate with companies that are creating solutions.
Six Irish healthcare companies will now be taking part in the demonstrator project. They include Abtran, which is working on a GP referral system in hospitals to reduce costs, improve waiting lists and improve patient care. Arann Healthcare is working with Cork University Hospital to develop a mattress sterilisation product.
Helix Health is pioneering an electronic prescription service to send prescriptions automatically from GPs to pharmacies. Radisens Diagnostics is working with hospitals to develop technology to allow GPs to take and process blood tests in their surgeries.
Rigney Dolphin is working with Cork University Hospital (CUH) to develop a post-discharge patient telephone follow-up programme. The aim is to help prevent avoidable re-admissions and to improve continuity of care. Sláinte Healthcare is developing paperless testing data with the Warfarin Clinic at CUH.
A collaborative venture between Enterprise Ireland, IDA Ireland, Science Foundation Ireland, the HSE, Cork Institute of Technology and University College Cork, the hub is being driven by the Department of Jobs, Enterprise and Innovation and the Department of Health.
Dave Shanahan, head of strategic health initiatives at Abbott and national project team chairman, said Ireland is now recognising the “critical role” the national healthcare system has in supporting domestic innovation and commercialisation.
“The global healthcare market of US$2.5trn requires ongoing product and service innovation. Ireland, with its unique concentration of pharmaceutical, medical device and ICT industries, is uniquely placed to exploit this market, provided we join up all elements of the value chain,” he said.
