 Discussion over Zoom

 Chair – Professor the Lord Broers

Speakers:

  •  Professor Sir Andrew Hopper – Treasurer and Vice-President of the Royal Society and Professor of Computer Technology at the University of Cambridge.
  • Professor Alastair Beresford, Professor of Computer Security, Queens College Cambridge

Lord Broers began the meeting by thanking everyone for attending and introduced the first of the distinguished speakers, Professor Sir Andrew Hopper.

 

Professor Sir Andrew Hopper

Professor Sir Andrew Hopper is Treasurer and Vice-President of the Royal Society and Professor of Computer Technology at the University of Cambridge. His research interests include computer systems, sensor-driven and location-aware computing, and using computer technology for sustainability of the planet. He is a Fellow of the Royal Academy of Engineering (1996) and of the Royal Society (2006). He was made a CBE for services to the computer industry (2007) and was knighted in the Queen’s Birthday Honours in 2021. In his commercial career, Professor Sir Andrew has founded thirteen start-ups, three of which floated on the stock markets. The companies he co-founded have received numerous Queen’s Awards for Enterprise and he is currently Chairman of RealVNC Group and lowRISC CIC.

Professor Sir Andrew offered some forward-thinking ideas on the topic. Sir Andrew noted the difficulties of large companies and monopolies dominating platforms. His framework gives an incentive to smaller companies to innovate in a safe and secure way.

Programmes and data that anybody can use should be made freely available to those within the UK domain. These are building blocks, with support and documentation, that enable individuals to innovate within a corporate and legal structure. If this were to happen, there would be no regional bias and it would be available to all. In a metaphorical sense, the person building the car does not have to also build the road, which is currently the case.

Removing monopolies will accelerate innovation and remove the sales aspect of digital infrastructure. Security and quality of security will be ensured, owing to a kite mark given by digital security services. It will also be sovereign to the UK and not available outside of British domains. This could prove to be the basis of technology sovereignty. This framework also enables new business models to be produced. Professor Sir Andrew turned to the environmental possibilities of a new digital framework, and how a more streamlined process could help the UK achieve its net zero ambitions.

In an ecosystem with ten companies using the same digital commons, even if they are competing with one and other, it is in their advantage to create a better and more competitive platform. Furthermore, the Treasury should incentivise innovation more through the implementation of tax breaks and subsidies.

Professor Sir Andrew ended his remarks talking about the company of which he is Chair, lowRISC, which is successfully using the aforementioned model.

Lord Broers then welcomed the second distinguished speaker, Professor Alastair Beresford.

Professor Alastair Beresford

 Alastair Beresford is Professor of Computer Security, Deputy Head of the Department of Computer Science and Technology, and the Robin Walker Fellow and Director of Studies in Computer Science at Queens’ College, University of Cambridge. His research work examines the security and privacy of large-scale distributed computer systems, often with a focus on the security and privacy of networked mobile devices, such as smartphones, tablets and laptops. He is also passionate about improving technology to support educators and learners and co-directs the tech team building and running the Isaac learning platform which has supported over 300,000 teachers and school children learning maths, physics and computer science since 2015.

Professor Beresford opened his remarks by explaining that systems already exist for sharing information (Wikipedia) and for code (GitHub), but sharing information related to humans is harder. This data does not necessarily contain direct personal information such as a name and address but could indirectly lead to sensitive personal information being identified. The Census is an example of this, in a non-digitised format. The cheap costs of computer processing means that we can share and cross-correlate data across networks but that we need to factor in the potential privacy risks.

Professor Beresford highlighted two projects that he has been working on. The first is Device Analyser, and Android app and associated server software that collects data on how individuals use their smartphones. This did not mean any one individual’s data was used or identified and has had significant benefits in research terms and for wider society.

The second project Professor Beresford is involved with works with the Cambridge Cybercrime Centre. This is looking at ‘badness’ on the internet and ways to mitigate against this. Again, this data is shared with other researchers and does not involve the sharing of any one individual’s data.

Professor Beresford ended his remarks by highlighting an example of data obtained by the New York Times, showing the precise location of 12 million devices in the US. This data can be used maliciously, by linking work and personal data to electoral registers and tax records to determine the identity of each individual. Within a digital commons, there needs to be a set of regulations that respect privacy and security principles to ensure that data is not used harmfully.

 

 Questions and Answers

Q1 – Professor The Lord Broers

Question – What is the main benefit of this commons? Is it for researchers or for the benefit of everybody?

Answer – Professor Sir Andrew Hopper

This is mostly aimed at industry. The platform will not be accessible for everyone, there will be groups of companies using it, depending on the topic most aligned with themselves. It needs to be savvy and work in each individual domain, ensuring privacy and security properties.

 

Q2 – Ken Sanders

Question – How do companies protect their own intellectual property on shared platforms?

Answer – Professor Sir Andrew Hopper

Companies can keep their own intellectual property secret from competitors – this does not get shared. Furthermore, going forward, companies may start creating their own platforms, away from the digital commons.

 

Q3 – Ian Deane

Question – There are big opportunities in the transport sector, and I for one would be a big advocate of sharing data to improve traffic and travel.

Answer – Professor Alastair Beresford

A digital commons that allows us to bring together traffic and travel data would be very useful. Rather than providing data to one large group of companies, it would be beneficial to allow SMEs to access this data to increase innovation.

 

Q4 – The Lord Mair

Question – There is a difficulty with commercial digital information that companies are reluctant to give out. However, for the public good, it is in the interests of society to have this digital data. Is this something that you think can overcome and does government need to legislate to enforce the release of this information.

Answer – Professor Sir Andrew Hopper

Incentives, with a form of government legislation, is needed. It is possible to find a boundary between information that is shared for the public good and commercial information that is kept private. There are advantages for companies to share information on a public platform and companies like Google are already doing so. Investing in digital platforms can be done through the implementation of incentives, such as a reduction in rates paid of corporation tax from companies furthering the public good.

 

Q5 – Edward Gochman

Question – If companies are pushing data sets, how can we stop companies with the most useful data from publishing partial data sets that reduce competition?

Answer – Professor Alastair Beresford

We can lean on digital reputations and mandate companies to include digital signatures on any data they publish, so any faults or missing data items can be detected. This could then lead to sanctions.

               Answer – Professor Sir Andrew Hopper

The model needs to include governance. Companies that provide faulty data would blot its copybook with other companies, the Government and the public.

 

Q6 – Professor The Lord Broers

Question – There are companies who want their application to be used rather than others when accessing and using data, to the extent that some disable their applications when used with others. Can this be coped with?

Answer – Professor Sir Andrew Hopper

It is all about incentives. Advantages of a common platform with companies feeding back to better the platform can already be seen from numerous examples. However, it should be noted that there is not universal trust in large companies. An intermediary organisation responsible for data sharing is needed.

Q7 – Quentin Spotterswood

Question – Once data has been collated from various sources, how is it possible to safeguard against reverse engineering and how do we protect against overly-invasive commercial behaviour?

Answer – Professor Alastair Beresford

There are technical methods we can use to guard against reverse engineering. Legal and other incentive mechanisms should not be discounted. In the transport sector, there is an opportunity for legislation to encourage companies to behave fairly, such as requiring bus companies to provide real time data as to where their buses are thereby providing a level playing field.

 

Q8 – Ian Deane

              Question – How do we tie in with the Government’s national data strategy?

Answer – Professor Alastair Beresford

Attempts have been made to provide public data sets, with mixed success. One of the areas which is more complex is where the data cannot be shared publicly, for privacy, security, and Intellectual Property reasons, but there is huge value to the general public embedded within these data sets.

 

Q9 – William Milligan

Question - From my understanding, you are advocating a partnership between industry and academia, where data is shared up to the point that it becomes commercially sensitive. Is this correct?

Answer – Professor Andrew Hopper

All the components are easily available; it is not just the data but the platform that is free of charge. For example, rather than using Zoom or another video conferencing platform, the components to do this are already available and can therefore be done by anybody. It will be hard to achieve net zero without innovation such as this.

 

Q10 – Professor The Lord Broers

Question – I receive a lot of correspondence regarding when we will receive a comprehensive roadmap to achieving net zero. Could this help to do that?

Answer – Professor Sir Andrew Hopper

Yes of course – look at the pandemic, which facilitated innovation not too far from what we are advocating. Intellectual Property barriers were reduced and there was a higher level of collaboration. This has shown that it can be done successfully. Everything in future will include a digital component so innovation and collaboration must occur.

 

Q11 – Professor The Lord Broers

Question - What might this mean for young people and how can they contribute?

Answer – Professor Alastair Beresford

They can take part in several ways, such as sharing their own data. They can also start their own companies, and whilst now it can be quite capital heavy to do this, a platform like the one described could reduce this barrier to entry.

 

Q12 – Professor The Lord Broers

Question – How do we stop Mr Putin and others putting false data onto this system?

Answer – Professor Alastair Beresford

 This comes back to an earlier point about how we authenticate the parties that are on the platforms and contribute to them. There are computer security techniques to attribute data sets or code to parties. That is not to say malice is not impossible, and foreign governments could register a UK company to slowly push the platform off course.

Answer – Professor Sir Andrew Hopper

A process like this means that there is a framework that all contributors need to follow. It could also open dialogue between states.

 

Professor the Lord Broers closed discussions by thanking our distinguished speakers, excellent guests and event organisers, particularly in these challenging times. It is hoped that events will return to the House of Lords as soon as guidance permits.

Low Carbon Aviation

The All-Party Parliamentary Group for Engineering

1 March 2020

 Low Carbon Aviation

  Discussion over Zoom

 

Chair – Professor the Lord Broers

Speakers:

•   Paul Stein – Chief Technology Officer, Rolls Royce

•   Professor Rob Miller – Chair in Aerothermal Technology and Whittle Lab Director, University of Cambridge

 

Lord Broers began the meeting by thanking everyone for attending and introduced the first of the distinguished speakers, Paul Stein.

 

Paul Stein – Rolls Royce

Paul Stein is the Chief Technology Officer at Rolls Royce and is responsible for Rolls Royce’s technology investment, ensuring close alignment with business strategy. His previous roles at Rolls Royce include Chief Scientific Officer, a role he had held between 2010 and 2016, and Director of Research and Technology from 2016 – 2019. He is also on the board of Energy Technologies Institute LLP and received an honourary degree from the University of Derby in 2017.

Addressing the virtual meeting, Paul highlighted the need to get to net zero by 2050 to limit the impacts of climate change. One of the key ways to achieve this is to stop using fossil-based jet fuel, as aviation accounts for 2.6% of global emissions, and 7% of globally used crude oil is used as jet fuel.

Paul then discussed some of the initiatives that are being explored by the industry to reduce emissions in line with the 2050 target. Citing that 70% of fuel is used for trips over 1500km, the industry is particularly excited about sustainable aviation fuel’s (SAFs). Amongst these are synthetic hydrocarbon that originate from atmospheric forces rather than fossil fuels. Furthermore, efuels synthesise fuel into aviation fuel, and this process is carbon neutral.

SAFs and hydrogen are both net zero and have the same atmospheric impact. It is also important to consider fuel economics and efficiency. Improving efficiency lowers overall consumption. Finding solutions in a relatively short period of time is another challenge to overcome; technology that will not be completed within 20 or 30 years will not help reach net zero by 2050. Quick engineering maturity is needed to achieve this goal.

Recent tests on electric aircraft have highlighted the potential of this technology but also some of its limitations. Current technology is limited to 200 miles and is able to carry 19 passengers. One of the key issues with this technology is battery size and the amount of electricity that can be stored within it.  Another option to reach net zero is the advancement in hydrogen technology. Hydrogen can be compressed into a tank and through the use of a fuel cell can be turned into fuel.

Paul ended his remarks by saying that he believes aviation can get to net zero by 2050, although it will require major changes to reach that goal. This will be driven by major changes to larger aircraft consuming SAFs rather than fossil fuels. Furthermore, for short range flights, airplanes can use a mix of hybrid, hydrogen and electric power.

 

Lord Broers then welcomed the second distinguished speaker, Professor Rob Miller.

Professor Rob Miller – Cambridge University

 Professor Rob Miller is Chair in Aerothermal Technology, Director of the Whittle Laboratory and Director of the Rolls-Royce Whittle University Technology Centre at the University of Cambridge. In 2013 he set up and led the UK Engineering and Physical Sciences Research Council Centre of Doctoral Training in Gas Turbine Aerodynamics, a partnership between Cambridge, Oxford, and Loughborough Universities, aimed at training the next generation of leaders in the aerospace and power generation sectors. He is a member of the UK Department for Transport Science Advisory Council. His research focuses on the decarbonisation of the aerospace and power generation sectors. His honours include the Institution of Mechanical Engineers Thomas Hawksley Gold Medal (2010) and the American Institute of Aeronautics and Astronautics Air Breathing Propulsion Award (2008). He has won the American Society of Mechanical Engineers Best Paper Award eight times and their highest honour in the field, The Gas Turbine Award, four times.

Professor Miller opened his remarks stating that one return flight from London to New York produces more Carbon Dioxide (986kg) than individuals in developing countries produce in a year. This shows the scale of emissions produced by the aviation industry. He said that the good news was that the decarbonisation of aviation is possible.  However, the size of the challenge is immense.

He then turned to possible paths to decarbonising aviation. The first Professor Miller highlighted was battery electric flight . If powered by renewable electricity, this removes from the process both the CO2 and non-CO2 bi product of aviation. The problem with battery electric is the weight of the battery limiting potential range to about 250 miles.

Another option being explored is the use of SAFs. This would use renewable electricity to electrolyse water to produce hydrogen and oxygen. Carbon is then either pulled directly from the air or is sourced from sustainable biomass and then combined with the hydrogen using the Fischer Tropsch process to create a switch-in fuel. Using this method, you don’t have to change the infrastructure that currently exists within the aviation industry. One of the principal issues with SAFs is the sheer quantity that needs to be produced. To give an idea of the scale he said that if all of the renewable energy generated by wind in the UK last year was used it would be enough to create 1/6 of the air fuel used by the UK.

A third option on the pathway to decarbonisation is to power aircraft using hydrogen. Airbus have said that they would have a commercially available aircraft by 2035. This method will probably use around a half the renewable electricity of the SAF option. The problem is that this option will require new aircraft and new infrastructure and has a range limited to about 2000 miles.

Professor Miller then discussed the work undertaken at the Whittle Laboratory, the world’s leading jet engine laboratory. It works with and its success is linked to partnerships with Rolls-Royce and other companies. They have focused on speeding up the technology development process. Traditionally the aviation sector has taken 6-10 years to develop a single new technology. The Whittle Laboratories aim has been to reduce this by an order of magnitude. Drawing on inspiration from Formula 1, a rapid technology department has been created. New design systems linked directly to in house manufacturing processes and rapid test facilities. By changing 95% of processes this was shown to reduce the time to design, build and test a new concept from  months to days. This has created a new culture as the pace of innovation increases.

Professor Miller concluded his remarks by explaining the need to take a whole systems approach to decarbonisation of the aviation sector. At a recent roundtable set up by The Prince of Wales the Aviation Impact Accelerator had been set up. This was a whole system approach to accelerating the delivery, scale-up and the associated infrastructure, investment, and policy in partnership between Cambridge, the Sustainable Markets Initiative, and the World Economic Forum.

  

Questions and Answers

Q1 – Laurence Robertson MP

Question – In order to get the technology in time to reach the 2050 target, is it a matter of how quickly technology can be created or is it a funding issue?

Answer – Paul Stein

Aviation is a global industry and therefore whilst the UK can take the lead on solving many of the problems, it needs to be a global response. SAF scale-up is a big problem; crude oil accounts for 4% of global GDP and this needs to be repurposed over the next 20-30 years. There needs to be a redeployment of trillions of dollars of capital globally. Government’s need to co-ordinate on a global level to solve problems.

Answer – Professor Rob Miller

The world needs to adopt a war-like mentality to achieve the necessary pace of technological advancements. During the Cold War, Kelly Johnson developed the A12 in four years to first flight, and this dominated the sky for a generation. However, because the aviation sector has been relatively stable for 40 years it is currently not well placed to achieve this pace of technology development. There also needs to be sophisticated policy to look at the various pathways to decarbonization.

 

Q2 – Bridget Donaldson

Question – What should policymakers do in the UK to drive both national and international progress?

Answer – Paul Stein

Paul began his answer by stating that in his opinion, there are two ways to help the SAF scale-up. Firstly, through the use of international bodies and summits, like COP26, a pathway to making SAF’s cheaper and more widely available needs to be agreed amongst global players. Secondly, there needs to be an alignment of research pathways over the next 10 years to develop new technologies that make things like SAF’s easier to produce.

 

Q3 – Finlay Asher

Question – What emissions price (£ per tonne CO2) do the participants expect for aviation emissions in 2030 and 2040?

Answer – Professor Rob Miller

If you look at the way that wind has been unlocked in the North Sea, the government has incentivized companies to move into that area resulting in a price reduction. The government needs to look at policies that incentivize businesses to enter the industry to explore the different pathways to decarbonization. In his personal view, the world will fly less in the future, but the cultural and economic benefits of flying mean high rates will persist. It would also be morally wrong to deny developing countries the right to enjoy its benefits. However, we have to be honest with the public on the importance of delivering this.

Answer – Paul Stein

Policy could come in the form of a requirement to use sustainable fuels rather than a tax on fossil fuels.

 

Q4 – Edward Talboys

Question – Impurities in airplane fuel can clog up aircraft engines. Will there need to be a loosening of the limits to account for a reduction in the impurities in SAFs?

Answer – Paul Stein

There will be no loosening of the limits, precisely the opposite. Currently, fuel safety needs to be demonstrated to acquire certification. Synthetic fuels have fewer impurities to lubricate the seals. Research has focused on looking at new seals which can cope without the impurities from fossils. Currently, we can fly with a 50% blend of SAFs. The key difference between industry and academia is the pace of change. Industry need to be certain of safety before making any changes.

Answer – Professor Rob Miller

At Cambridge, our team has looked at over 238 possible future fuels. It is important to take a multi-disciplinary approach to understand all aspects of the fuel if they are to be of practical use in flight. Whatever the choice the fuel will require very rigorous testing before use.

 

Q5 – Amina Abid

Question – Would the efficiency of a car be reduced the larger the size of battery?

Answer – Paul Stein

The bigger a battery gets, the heavier it becomes to a point that it cannot lift itself. Growing battery size is only possible to an upper limit.

              Answer – Professor Rob Miller

Whilst battery technology alone would not be sufficient for medium and long range flights, using it in combination with other sustainable fuels could unlock other technology. For example, it could be used in combination with hydrogen fuel cells, which could be used when cruising at high altitude, whilst using the battery to help during take-off and climb.

 

Q6 – Kenneth Sanders

Question – Does pilotless flying have a role in improving aircraft efficiency?

Answer – Paul Stein

Currently moving from two pilot operations to trialing one pilot in the cockpit, where the AI system can land the plane should the pilot become incapacitated. The next step is to reduce pilot workloads and therefore training, and this is something that the military are particularly interested in. Future generations are likely to trust AI systems more.

Answer – Professor Rob Miller

Black box data is increasingly being looked at to monitor pilots, and this data is showing that variations in pilot behaviour is important. There may be some quick wins that could reduce carbon emissions by changing air traffic control, operations and pilot behaviour.

 

Q7 – Huw Williams

Question – As Rob and Paul have described, the energy infrastructure to deliver SAF’s sustainably does not currently exist. How do we ensure that the potential negative impact of SAF’s are highlighted and isn’t hidden in carbon trading?

Answer – Paul Stein

Any form of decarbonization needs to look at the whole carbon lifecycle, including relevant supply chains, in any decarbonization model. The UK electricity grid needs to double in size between now and 2050 just to cater for electric vehicles and other forms of sustainable transport, not even taking into account SAF’s production.

Answer – Professor Rob Miller

Any systems models that are produced need to be big enough to solve the real problem. It’s not good enough to replicate a subset of reality; models need to predict in their entirety. For example, you need to look at where your electricity to produce the SAFs is coming from, you need to factor in the journey of a person to the airport, and you need to consider the fuel burn in taxiing the aircraft before take-off.

Networking in the Livery

Past master Ken Sanders is regularly invited to a Parliamentary working group, the All Party Parliamentary Engineering Group. More details can be found at: http://appeg.co.uk/.

It stages discussions over luncheon or dinner, in the House of Lords, on various engineering topics, to involve politicians from both houses, school students and young engineers to be involved and debate Engineering issues. It is a good networking forum, and I have the opportunity to take a number of our Apprentices and Freemen to participate.

During the Pandemic, events are virtual and the March event was on the topic of Low Carbon Aviation. One of the speakers was Paul Stein, Chief Technology Officer at Rolls Royce.

One of the Livery attendees, Freeman Bridget Donaldson (a student at Oxford University? )who has a keen interest in the topic, asked after the event if it would be possible to have a conversation with Paul. Ken was able to facilitate that with the organisers, with a very positive outcome.

Bridget reported that a further conversation went well and she is now in talks with Rolls Royce over working together on future research.
