This week, I had the opportunity to join the launch of the UKERC’s latest research into the future of gas. The esteemed delegates included members of a Russian Trade Delegation and several people from the US Embassy. Clearly, the future of gas is an international thing.

[MB] I’m somewhat daunted by this audience – the report is aimed perhaps for informed public audience. The media [ambushed us on the question of shale gas, shale gas attracted more attention] but things we didn’t cover much about there we can cover here. It’s been a real rollercoaster ride in the gas industry. Any flights of fancy (in the report) are our faults and not theirs [reference to work of colleagues, such as Jonathan Stern at Oxford Institute for Energy Studies]. A set of shortcomings dealing with the issue of Energy Security. There is a tendency to think that oil and gas are the same. They’re not. The framework, the actors and the networks, trade statistics, policies [much different for gas than for oil]. [In the UK for example we are seeing] a rapid increase in import dependence [and in other countries]. Need to [pay] particular understanding on what will happen in far-flung places. Today, the US-China agreement could influence gas demand. [In the literature on gas, some anomalies, perhaps]. Academics may not understand markets. [What we are seeing here is] the globalisation of UK gas security – primarily Europeanisation. There is growing uncertainty [about] the material flow of gas. [Threshold] balance in three sectors – strong seasonality, impact of climate and temperature [on gas demand]. The Russian agreement with Ukraine [and Europe] – the one thing everybody was hoping for was a warm winter. While the gas market is important [industrial use and energy use], domestic/residential demand is still very significant [proportion of total demand], so we need to look at energy efficiency [building insulation rates] and ask will people rip out their gas boilers ? For the UK, we are some way across the gas bridge – gas has enabled us to meet [most of] our Kyoto Protocol commitments. Not long until we’ve crossed it. Our coal – gone. With coal gone, what fills the gaps ? Renewable electricity – but there is much intermittency already. We’re not saying that import dependency is necessarily a problem. Physical security is not really the problem – but the [dependence on] the interconnectors, the LNG (Liquefied Natural Gas) imports – these create uncertainties. The UK also plays a role as a gas exporter – and in landing Norwegian gas [bringing it into the European market]. I’m a geographer – have to have at least one map – of gas flows [in and out of the country]. The NTS (National Transmission System – the high pressure Natural Gas-carrying pipeline network – the “backbone” of the gas transmission and distribution system of National Grid] has responded to change – for example in the increasing sources of LNG [and “backflow” and “crossflow” requirements]. There are 9 points of entry for gas into the UK at the moment. If the Bowland Shale is exploited, there could be 100s of new points of entry [the injection of biogas as biomethane into the gas grid would also create new entry points]. A new challenge to the system. [The gas network has had some time to react in the past, for example] LNG imports – the decision to ramp up the capacity was taken a long time ago. [Evolution of] prices in Asia have tracked the gas away [from the European markets] after the Fukushima Dai-ichi disaster. And recently, we have decided to “fill up the tanks” again [LNG imports have risen in the last 24 or so months]. Very little LNG is “firm” – it needs to follow the market. It’s not good to simply say that “the LNG will come” [without modelling this market]. The literature over-emphasises the physical security of the upstream supplies of gas. [The projections have] unconventional gas growing [and growing amounts of biogas]. But it’s far too early to know about shale gas – far too early to make promises about money when we don’t even have a market [yet]. Policy cannot influence the upstream especially in a privatised market. The interconnectors into the European Union means we have to pay much more attention to the Third EU Energy Package. Colleagues in Oxford are tracking that. The thorny question of storage. We have less than 5 bcm (billion cubic metres). We’d like 10% perhaps [of the winter period demand ?] Who should pay for it ? [A very large proportion of our storage is in one place] the Rough. We know what happens – we had a fire at the Rough in 2006… Everyone worries about geopolitics, but there are other potential sources of problems – our ageing infrastructure […] if there is a technical problem and high demand [at the same time]. Resilience [of our gas system is demonstrated by the fact that we have] gas-on-gas competition [in the markets] – “liquid” gas hub trading – setting the NBP (National Balancing Point). [There are actually 3 kinds of gas security to consider] (a) Security of Supply – not really a problem; (b) Security of Transport (Transit) – this depends on markets and (c) Security of Demand – [which strongly depends on whether there is a] different role for gas in the future. But we need to design enough capacity even though we may not use all of it [or not all of the time]. We have mothballed gas-fired power plants already, for reasons you all know about. We already see the failure of the ETS (European Union Emissions Trading Scheme) [but if this can be reformed, as as the Industrial Emissions Directive bites] there will be a return to gas as coal closes. The role of Carbon Capture and Storage (CCS) becomes critical in retaining gas. CCS however doesn’t answer issues of [physical energy security, since CCS requires higher levels of fuel use].
[Question from the floor] Gas has a role to play in transition. But how do we need to manage that role ? Too much focus on building Renewable Energy system. What is the impact on the current infrastructure ? For managing that decline in the incumbent system – gas is there to help – gas by design rather than gas by default.
[Question from the floor, Jonathan Stern] [In your graphs/diagrams] the Middle East is a major contributor to gas trade. We see it differently. The Qataris [could/may/will] hold back [with expanding production] until 2030. Iran – our study [sees it as] a substitute contributor. Oil-indexed gas under threat and under challenge. If you could focus more on the global gas price… [New resources of gas could be very dispersed.]Very difficult to get UK people to understand [these] impacts on the gas prices [will] come from different places than they can think of.
[Question from the floor] Availability of CCS capacity ? When ? How much ? Assumptions of cost ?
[Question from the floor : Tony Bosworth, Friends of the Earth] Gas as a bridge – how much gas do we need for [this process] ? What about unburnable carbon ? Do we need more gas to meet demands ?
[Answer – to Jonathan Stern – from Christophe McGlade ?] The model doesn’t represent particularly well political probabilities. Iran has a lot of gas – some can come online. It will bring it online if it wants to export it. Some simplifications… might be over optimistic. Your work is helpful to clarify.
On gas prices – indexation versus global gas price – all the later scenarios assumed a globalised gas price. More reasonable assumptions.
On CCS : first [coming onstream] 2025 – initially quite a low level, then increasing by 10% a year. The capital costs are approximately 60% greater than other options and causes a drop in around 10% on efficiency [because making CCS work costs you in extra fuel consumed]. If the prices of energy [including gas] increase, then CCS will have a lesser relative value [?].
On availability of gas : under the 2 degrees Celsius scenario, we could consume 5 tcm (trillion cubic metres) of gas – and this can come from reserves and resources. There are a lot of resources of Natural Gas, but some of it will be at a higher price. In the model we assume development of some new resources, with a growth in shale gas, and other unconventional gas. Because of the climate deal, we need to leave some gas underground.
[Answer from the panel] Indexation of gas prices to oil… Further gas demand is in Asia – it’s a question of whose gas gets burnt. [Something like] 70% of all Natural Gas gets burned indigenously [within the country in which it is produced]. When we talk about “unburnable gas”, we get the response “you’re dreaming” from some oil companies, “it won’t be our fossil fuels that get stranded”. LNG models envisage a different demand profile [in the future, compared to now]. When China [really gets] concerned about air quality [for example]. Different implications.
[Question from the floor, from Centrica ?] What’s in the model for the globalised gas price – Henry Hub plus a bit ? There is not a standard one price.
[Question from the floor] On the question of bridging – the long-term bridge. What issues do you see when you get to 2030 for investment ? [We can see] only for the next few years. What will investors think about that ?
[Question from the floor] [With reference to the Sankey diagram of gas use in the UK] How would that change in a scenario of [electrification – heat and transport being converted to run on electrical power] ?
[Question from the floor] Stranded assets. How the markets might react ? Can you put any numbers on it – especially in the non-CCS scenario ? When do we need to decide [major strategy] for example, [whether we could or should be] shutting off the gas grid ? How would we fund that ? Where are the pinch points ?
[Answer from the panel] On the global gas price – the model does not assume a single price – [it will differ over each] region. [The price is allowed to change regionally [but is assumed to arise from global gas trading without reference to oil prices.] Asian basin will always be more expensive. There will be a temperature differential between different hubs [since consumption is strongly correlated with seasonal change]. On stranded assets – I think you mean gas power plants ? The model is socially-optimal – all regions working towards the 2 degrees Celsius global warming target. The model doesn’t limit stranded assets – and do get in the non-CCS scenario. Build gas plants to 2025 – then used at very low load factors. Coal plants need to reduce [to zero] given that the 2 degrees Celsius targets are demanding. Will need gas for grid balancing – [new gas-fired power generation assets will be] built and not used at high load factors.
[Answer from the panel] Our report – we have assume a whole system question for transition. How successful will the Capacity Mechanism be ? UKERC looking at electrification of heating – but they have not considered the impact on gas (gas-to-power). Will the incentives in place be effective ? The Carbon Budget – what are the implications ? Need to use whole system analysis to understand the impact on gas. Issue of stranded assets : increasingly important now [not at some point in the future]. On pinch point : do we need to wait another three years [for more research] ? Researchers have looked more at what to spend – what to build – and less on how to manage the transition. UKERC have started to explore heat options. It’s a live issue. Referenced in the report.
[Question from the floor, from Richard Sverrisson, News Editor of Montel] Will reform to the EU ETS – the Market Stability Reserve (MSR) – will that be enough to bring gas plant into service ?
[Question from the floor] On oil indexation and the recent crash in the crude price – what if it keeps continuing [downwards] ? It takes gas prices down to be competitive with hub prices. [What about the impact on the economic profitability of] shale oil – where gas driving related prices ? Are there some pricing [functions/variables] in the modelling – or is it merely a physical construct ?
[Question from the floor, from Rob Gross of UCL] On intermittency and the flexibility of low carbon capacity. The geographical units in the modelling are large – the role of gas depends on how the model is constrained vis-a-vis intermittency.
[Answer from the panel, from Christophe McGlade] On carbon dioxide pricing : in the 2 degrees Celsius scenario, the price is assumed to be $200 per tonne. In the non-CCS scenario, the price is in the region of $400 – $500 per tonne [?] From 2020 : carbon price rises steeply – higher than the Carbon Floor Price. How is the the 2 degrees Celsius target introduced ? If you place a temperature constraint on the energy system, the model converts that into carbon emissions. The latest IPCC report shows that there remains an almost linear trend between carbon budget and temperature rise – or should I say a greenhouse gas budget instead : carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). The emissions pledges of the [European Union ?] have been adopted by this model – also the development of renewable energy and fuel standards. No exogenous assumptions on carbon pricing. On intermittency – the seasonality is represented by summer, winter and intermediate; and time day generalised as morning, night, evening and peak (morning peak). [Tighter modelling would provide more] certainty which would remove ~40% of effective demand [?] Each technology has a contribution to make to peak load. Although, we assume nothing from wind power – cannot capture hour to hour market. The model does build capacity that then it doesn’t use.
[Answer from the panel] On carbon pricing and the EU ETS reform : I wouldn’t hold my breath [that this will happen, or that it will have a major impact]. We have a new commission and their priority is Poland – nothing serious will happen on carbon pricing until 2020. Their emphasis is much more on Central European issues. I don’t expect [us] to have a strong carbon price since policy [will probably be] more focussed on social democracy issues. Moving to a relatively lower price on oil : Asia will hedge. Other explorters currently sticking to indexation with oil. The low price of wet gas (condensate) in the USA is a result of the over-supply, which followed an over-supply in NGLs (Natural Gas Liquids) – a bumpy road. Implications from USA experience ? Again, comes back to watching what is happening in Asia.
