Titled 鈥楾he road to net zero: renewables and nuclear working together鈥�, the report shines a spotlight on the flexibility of nuclear as an energy source and its potential in a net zero future.

The report offers a fresh perspective on nuclear, which 鈥� until now 鈥� has not often been seen as a flexible technology because it operates best when run flat out continuously. However, in addition to nuclear reactors producing electricity, the process produces nuclear-enabled heat and hydrogen, a storable standby energy source.

While the experts agree that renewable energy sources should be a major contributor to future energy strategy, there is an argument that nuclear energy can complement the variability of renewables contending with the UK鈥檚 island weather system 鈥� negating the need to rely on expensive back-up natural gas power plants.

Zara Hodgson, Director of the Dalton Nuclear Institute at 51福利社 said: 鈥淭he time to research, evaluate and plan for the delivery of a clean energy future is now 鈥� and the clock is ticking. We hope this report will prompt debate within the energy sector and help to inform policy, so that Great Britain is in the best possible position to meet its ambitious 2050 net zero target.

鈥淕reat strides have already been made in driving forward renewable energy initiatives and moving away from fossil fuel burning power plants. And as part of an integrated approach to Great Britain鈥檚 future energy mix, nuclear can help ensure gas power plants do not play a key role.鈥�

Included in the report are the Dalton Nuclear Institute鈥檚 ten recommendations to government and industry for effective net zero road-mapping, including the need for decision-making on the future energy mix to consider the capacity factors of new and existing infrastructure. The delivery of low-carbon, cost-effective dispatchable electricity must also be prioritised to support the overall system.

Traditionally, proponents of renewables and nuclear have been divided in their viewpoints. However, the report stresses the importance of a joined-up approach where nuclear, renewables, energy storage and hydrogen production can all play their parts in a cleaner, greener future.

A decade ago, scientists at 51福利社 demonstrated that graphene is permeable to protons, nuclei of hydrogen atoms. The unexpected result started a debate in the community because theory predicted that it would take billions of years for a proton to permeate through graphene鈥檚 dense crystalline structure. This had led to suggestions that protons permeate not through the crystal lattice itself, but through the pinholes in its structure.

Now, writing in , a collaboration between the University of Warwick, led by Prof Patrick Unwin, and 51福利社, led by Dr Marcelo Lozada-Hidalgo and Prof Andre Geim, report ultra-high spatial resolution measurements of proton transport through graphene and prove that perfect graphene crystals are permeable to protons. Unexpectedly, protons are strongly accelerated around nanoscale wrinkles and ripples in the crystal.

The discovery has the potential to accelerate the hydrogen economy. Expensive catalysts and membranes, sometimes with significant environmental footprint, currently used to generate and utilise hydrogen could be replaced with more sustainable 2D crystals, reducing carbon emissions, and contributing to Net Zero through the generation of green hydrogen.

The team used a technique known as to measure minute proton currents collected from nanometre-sized areas. This allowed the researchers to visualise the spatial distribution of proton currents through graphene membranes. If proton transport took place through holes as some scientists speculated, the currents would be concentrated in a few isolated spots. No such isolated spots were found, which ruled out the presence of holes in the graphene membranes.

Drs Segun Wahab and Enrico Daviddi, leading authors of the paper, commented: 鈥淲e were surprised to see absolutely no defects in the graphene crystals. Our results provide microscopic proof that graphene is intrinsically permeable to protons.鈥�

Unexpectedly, the proton currents were found to be accelerated around nanometre-sized wrinkles in the crystals. The scientists found that this arises because the wrinkles effectively 鈥榮tretch鈥� the graphene lattice, thus providing a larger space for protons to permeate through the pristine crystal lattice. This observation now reconciles the experiment and theory.

Dr Lozada-Hidalgo said: 鈥淲e are effectively stretching an atomic scale mesh and observing a higher current through the stretched interatomic spaces in this mesh 鈥� mind-boggling.鈥�

Prof Unwin commented: 鈥淭hese results showcase SECCM, developed in our lab, as a powerful technique to obtain microscopic insights into electrochemical interfaces, which opens up exciting possibilities for the design of next-generation membranes and separators involving protons.鈥�

The authors are excited about the potential of this discovery to enable new hydrogen-based technologies.

Dr Lozada-Hidalgo said, "Exploiting the catalytic activity of ripples and wrinkles in 2D crystals is a fundamentally new way to accelerate ion transport and chemical reactions. This could lead to the development of low-cost catalysts for hydrogen-related technologies."

The Department for Energy Security and Net Zero provides dedicated leadership focused on delivering security of energy supply, ensuring properly functioning markets, greater energy efficiency and seizing the opportunities of net zero to lead the world in new green industries.

The funding from the Low Carbon Hydrogen Supply 2 programme comes from the  department鈥檚  拢1 billion , which provides funding for low-carbon technologies and systems and aims to decrease the costs of decarbonisation helping enable the UK to end its contribution to climate change.

This project will develop and validate a novel and inexpensive game-changing hydrogen separation technique that builds upon Powerhouse Energy's expertise in waste treatment and the international track-record of Dr Amir Keshmiri鈥檚 in fluid dynamics and thermochemical analysis.

This potential breakthrough in advanced thermal treatment to recover hydrogen from unrecyclable wastes could make a significant contribution to the UK鈥檚 net zero targets and reduce project costs compared to existing recovery methods - also, as well as being 鈥漡reener and cheaper鈥�, this new technology would be an important asset to help secure UK energy security at a time of major crisis and uncertainly.  

The rapid development and commercialisation of the invention, that the collaboration will directly support achieving the installed capacity target by 2030.

The project, which is initially funded by the grant, effectively encourages the swifter adoption of local, cleaner, low carbon energy - while addressing a growing unrecyclable waste issue, working within the existing waste hierarchy framework.

Mr Paul Emmitt, Chief Operating Officer and Executive Director at Powerhouse Energy (PHE), said the project will allow PHE to edge closer to overcoming significant cost barriers through innovation to deliver the next generation of cleaner energy technology. The pioneering technique, once commercialised, will enable the faster rollout of inexpensive hydrogen.

He added: 鈥淭he invention has the potential to overcome a significant cost prohibitive factor for commercial hydrogen extraction from Syngas [ie synthesis gas, a hydrogen-based mixture that can be used as a fuel not just for PHE, but all next generation advanced thermal technologies, potentially allowing more facilities to be developed for the same available capital, enhancing production towards and even beyond the ambitious 5GW target. Quantifying the impact for PHE, the proposed hydrogen separation technique has the potential to reduce project costs by up to 17.5%, or over 拢400m for 59 facilities.鈥�

Dr Amir Keshmiri, Associate Professor in Computational Fluid Dynamics at 51福利社, said: 鈥淭he collaboration allows 51福利社 to be at the forefront of high-impact, game-changing technology development within the emerging clean hydrogen energy sector - and allows the academic team to capitalise on the bespoke hydrogen models developed to a wider audience.

Dr Kashmiri said clean energy from hydrogen 鈥� dubbed 鈥榞reen hydrogen鈥� - will be have a flagship spotlight at COP27, the climate change summit currently being hosted in Sharm el-Sheikh. He added: 鈥淧roduction and storage of low-carbon hydrogen is one of the key themes of COP27 which is hosted by Egypt as part of the .鈥�
