incotecoTwists & Turns
• 1997, Labour comes to government with election aspiration to reduce domestic GHG by 20%, by 2012
• 1998 White paper, ”Energy Sources” – Mandelson, short-lived gas power station embargo to help coal!
– Power companies pilloried for free market views– Gas embargo lifted by Byatt in 2000
• 2001 – 2002 NETA leading toward BETTA, a flagship Labour policy– Realigning regulation & market forces– Bankrupting major power generators– Making ”big” capacity investments more risky
• 2003 White paper, ”Our Energy Future” –– Renewables uppermost with little thought for capacity requirements and
attendant network investments– ”nuclear unnecessary”– ”gas supplies no problem”
• 2005 – 2006 ”Energy Review”– Nuclear suddenly seen as ”necessary” to meet GHG targets
• 2007 – ”Meeting the Energy Challenge”– New nuclear reviews and consultations
Ten years of ill-informed consultation took the place in place of serious policy formation

incotecoA shortage of carbon may halt our economy
...and radically reduce carbon emissions• Globally, we are exploring for, mining, processing and burning
about 16,000 t carbon per minute• The energy released and products produced under-lies our
enormous prosperity• We may be seeing the beginning of ”peak oil” ...• ...which happens when total output from the World’s oil
reservoirs can no longer be increased because depletion from existing oil fields exceeds new finding and oil field development– Caused as much by political, economic and social considerations
as geological reality– Why would the few remaining net oil exporters wish to accelerate
the day when they also become net importers?• Peak oil will mark a paradigm shift for all mankind.• Badly handled it will cause economic decline, starvation and war
The IPCC’s fundamental assumption is for continued smooth economic growth, even if the resources are not there to support this
4
incoteco
Resource constraints were not considered in the energy consultations• The bull-run in energy prices were considered
throughout the process as ”temporary” and ”untypical”
• The energy price projections used throughout foresaw falling or stable prices to 2020 and beyond
• The wish that energy markets should be open, transparent and unconstrained was treated throughout the consultation process as if these conditions have been achieved
• The reality is otherwise

11 GW has ”opted out” and will close after 20,000 hours
By 2016 these must conform to LCPD NOx requirements
12

Just a thought!!
Why is it that a European directive on acid emission reduction is necessary to close down Europe’s largest, least efficient and most polluting coal fleet?
Labour came into power on a commitment to reduce greenhouse
gases!

So UK faces ”turning the lights out” or a 30 GW new build in next ten years!

For 9 years UK Government has believed the gap can be filled with renewables & gas
Chart from ”Our Energy Challenge” July 2006. Experience & events of 2006 reveal this to be unrealistic.

Wind gives no capacity security
• For ”renewables” read ”wind”• There were 2 weeks last Christmas
when the wind did not blow over most of northern Europe– Weather systems can be enormous
• Irish experience is that during periods of annual maximum demand, the wind does not blow!

Global Gas supplies will remain tight• US & Canadian supplies are plateauing while demand grows
– Fulfilled by LNG• Indonesia cannot fulfill its contracts with Asian customers
– Which Qatar is fulfilling• Iran and Saudia Arabia, although large producers with growing
output, are using all their own production domestically• Algeria, Australia, Malaysia, Trinidad have no spare capacity• Nigeria is a war zone• Growing LNG capacity in Qatar is only realistic ”new” source but
demand is stretching its ability to deliver spot gas during cold weather– There are no plans to increase LNG exports beyond 77 million t/y
from Qatar after the completion of LNG trains at R’as Laffan• Other gas sources are really small

Europe must compete for the attention of gas suppliers
and UK must compete with other large and small consumers in
the EUOnly Ireland is further away from Easten Siberia!
31
incotecoConclusions
1. A capacity crunch is imminent in the UK, • due to the rapid closure of capacity operating today• During the first really cold winter• It is doubtful that European partners will waive the LPCD rules as it did
with the present generation of old and inefficient coal plants2. There is growing awareness that the gap cannot be filled quickly by
a nuclear rebuild and should not be filled by much more new gas capacity
3. Renewable power, mostly wind power, cannot supply the missing firm capacity
• Without masses of storage• MWh and MW are wrongly conflated, even in the 2007 White Paper!
4. GHG issues leave ”clean coal” as the only remaining large scale option that could be completed in the next 8 years
• But the UK Government is floundering in a spaghetti of ill-conceived incentives and regulations
5. Carbon capture and use for EOR will extend North Sea hydrocarbon reserves in excess of UK Kyoto commitments
• But we may get around to this just in time to see much of the oil infrastructure de-commissioned

That Flagship Policy is not working“The second factor was the design of the British electricity markets, and specifically NETA (and its gas counterpart). As a spot-based system, without a capacity element, as demand and supply converged, sharp volatility was to be expected. Indeed, this volatility was deemed to be a virtue: high price spikes would, it was argued, attract new investment”
Dieter Helm writing for the Social Market Foundation, 2006
Really serious, high value plant for the 21st
Century cannot wash its face under BETTA rules
33

It looks like the UK will have to muddle on and on...
...through the supply crises and price spikes that will be inevitable from the path followed during the last twenty years
• There will be inevitable and possibly protracted physical shortages of fuel and inevitable energy rationing
• An energy policy, taking into account resource constraints, will evolve, driven by technocrats who understand that the future is discontinuous with even the recent past – Not by accountants, economists and politicians– The economic damage caused by the muddle will be immense
• Exceptional opportunities will arise for those who can understand the seriousness of this situation early enough
34
incoteco
OpportunitiesWithout sounding too jingoistic, we are• The heirs of a great engineering tradition• The inheritors of great engineering master
works• A nation with a history of inventors,
buccaneers and devil-may-care risk takers• Now we write reports and do consultations!• …and irritate our friends and rivals with post-
colonial, moralistic fervour
What on earth has gone wrong that we cannot put right?
35
incoteco
Anything that can spin will be on......and will command a premium price• …especially if it can deliver MW according to
requirements• Can a large fleet of super-efficient, clean
coal, (CCS) plants be engineered, planned, financed, procured, constructed and commissioned with pipelines to UK’s dwindling oil and gas fields by 2016?– We will have to rebuild our domestic power
engineering construction capacity• Small scale generators will profit

It will be a great time for inter- building HVDC marine connectors

37

Energy storage will come into its own• Willy nilly a huge wind carpet is building up,
on and offshore, able to supply MWh– But not MW as and when needed
• Storage can transform this:– It is doubtful that we can engineer more pumped
hydro in Wales and Scotland– …existing pumped hydro will command a premium– …and offshore tidal/wind lagoons can perform as
stores and harbours for offshore wind and tidal energy
– Compressed air energy storage may provide some opportunity
• At a rather low (50 – 60%) round-trip energy efficiency• …and requires ideal geology

VRB Flow Battery TechnologyVRB Flow Battery TechnologyA liquid electrolyte that is separate from the electrode.
• An electrochemical energy storage system operating at ambient temperatures
• Reversible fuel cell – reduction and oxidation of single unique element: Vanadium
• No cross contamination• Electrolyte never wears out – high residual value• Very low maintenance• Deep cycles (20 to 80%) >10 years life• Low self discharge – indefinite energy storage• Energy can be recovered instantaneously• Battery can recharge as fast as it discharges (1:1)• Power and Energy separately scaleable

Wrap-up• Resource competition and energy scarcity will drive
Global energy use in the next decade– It will not be pretty
• Global warming concerns will give way to the need to keep the lights on
• …and in any case all the predictions for run-away emissions will be proven wrong
• The conditions will exist for creative destruction and massive reconstruction– But not if we do not take energy more seriously than
successive UK Governments• It is time for engineers to re-discover their importance
and responsibilities!
