I really wanted to write about shale gas economics and practicalities this
month because there’s a lot that needs saying.
However, I’m really going to have to sort this bloke Trump out because
he seems to be under the strange delusion that a golf course is more important
than Scotland’s industrial future.
Firstly, let me say that there are some aspects of his complaints and
those of others that have leapt conveniently onto the anti windfarm bandwagon
that I agree with. For example, I accept
the fact that wind energy is intermittent and that in certain weather
conditions it’s utterly useless.
However, the fact is that wind – and waves, tidal and solar - is here
for as long as the planet is whereas oil, coal, gas and even nuclear most
certainly won’t be because they are all dependent on inconveniently
increasingly expensive resources. Despite
TEA party type anti climate change squeals of patriotic hysteria over possible American
self-sufficiency even shale gas which is currently as cheap as chips in the USA
will go back up in price as gas drilling reduces and reserves are sold off to
bigger players who will ensure they make money out of it one way or the other.
Wind is then a viable long term resource and it’s actually really pretty
daft arguing about this. People may get
upset over subsidies being paid to windfarm owners many of whom aren’t even
from these shores and they may wish to complain that wind turbines are not
particularly elegant devices. Both views
are legitimate but not good enough reasons to stop wind turbine deployment
particularly offshore.
Similarly, there are concerns over noise and certainly bad planning
control of some onshore windfarms has led to what might be termed as “acoustic
rage” because turbines have been installed far too close to housing. This would seem though to be far less of a
problem with offshore wind turbines because they have considerably larger but
much slower and therefore quieter blades.
I find it interesting though that few people complain about the lack of
indigenous investment particularly in large scale wind turbine technology. Not many protest that none of the big
turbines are built here by UK let alone Scottish companies. Watching all those valuable sales falling into
overseas hands is my own major gripe about the industry and to a large extent one
of the reasons I support strongly the development of the European Offshore Wind
Deployment Centre (EOWDC) which is of course the windfarm that Trump is
complaining is going to spoil the view from his golf course.
So far the development of wind energy technology has been fairly
straightforward and predictable. We have
progressively larger capacity turbines moving offshore where there’s plenty of
space using latest generation direct drive – no gearbox – systems with lots of
built in condition monitoring stuff all aimed at generating electricity that
can be transmitted ashore via a fat cable – which incidentally we don’t
manufacture either. The cable usually forms part of a subsea grid laid by cable
vessels which we also don’t build. In
fact I don’t think we operate one now either do we?
So why do we need the EOWDC?
Because where we are now with wind technology is only the
beginning.
The industry still needs more efficient generators, systems that will
start generating at much lower windspeeds, more efficient and “stealthier” blade
designs, cheaper and better foundation designs, improved condition monitoring
and control devices, better access methodologies, more effective maintenance
methods and hardware replacement techniques.
There is also work to be done on power transmission, cables, connectors,
switchgear and so on and so forth.
Most important of all though, we need to develop technologies to tackle
the intermittency issue. In short that means energy storage. It’s the “holy grail” for wind. How to make sure windfarms are productive
100% of the time or as close as possible to 100% as we can get.
Maybe that doesn’t mean moving electricity onshore but producing
something else that can be stored and turned into electricity later. Work is
already going on with big batteries and we could use pumped hydro. Perhaps though
we should be using the electricity to run large scale electrolysers that
produce hydrogen that can be piped ashore. Some of that hydrogen can then be
used to fire gas turbines to generate electricity for the grid and some can be
stored to be used as a means of backing up the supply in times of low wind or
indeed too much wind.
Actually this is of course what the PURE project is doing on Shetland although
on an albeit much smaller scale.
Add to this though the possibility of using that hydrogen to produce
ammonia for use as a liquid transport fuel and wind technology will become even
more attractive.
So wind technology isn’t just throwing up opportunities now for high
technology high value adding Scottish companies but I personally have no doubt
that it will form a major part of the core of our future energy structure. It’s
just that we haven’t yet scratched the surface of what we can do with it.
Now I don’t want to get into commenting on Donald Trump’s golf course
plan because I’m not a golfer. I’ve never seen the attraction. What I do know
about golf though is that as far as I can tell from Scottish Development
International’s data base Scotland only has one golf related manufacturer which
is a company making clubs down at St Andrews.
It’s not fair perhaps to make such a comparison but it would appear then
that the industrial potential arising from the EOWDC project is going to be
considerably larger than Mr Trump’s golf course. However, I see no reason at all why the two
shouldn’t co-exist. In fact, if I was Mr Trump I’d use the EOWDC as a selling
point to attract wealthy overseas investors and industrialists!! No? Oh well – he’ll just have to live with it
then.
