Viewpoint: New gas plants or new cables?

This month Energy watchdog chief, Alistair Buchanan did a brilliant job at highlighting the current government energy strategy; 'we are going to lean heavily on gas’ and gas prices will unavoidably go up.

But Alistair proposes little to avoid us going down this road. In fact, he explains, it is unavoidable because there is ‘no new nuclear, no new clean coal'. But are there other options?

The answer on the tip of many tongues is fracking. The US has done it, a country 40 times the size of the UK with population density 1/8th of ours, so why can’t we?

The experience of onshore wind suggests otherwise. Getting planning permission can be nightmare thanks to well organised anti-wind farm groups opposed to new turbines.

… now add the questionable environmental credentials of shale gas (real or perceived) and the potential of shale seems limited. 

An alternative would be to focus on diversification – superficially government policy. First and foremost, this requires a greater emphasis on reducing our energy demand. Reduction is at the top of the hierarchy of environmental priorities but today our demand is not likely to change much between now and 2020.The government must aggressively pursue multiple demand reduction strategies and scale up the successful ones.

Secondly, we have to look at diverse technological solutions for our electricity supply and generation. Coal is no longer an option, nuclear will take too long to build, so what does that leave us with? We are pursuing wind energy but intermittency reduces its contribution to the reserve capacity, so it needs balancing technologies; gas, storage or interconnectors.

Gas is arguably the worst balancing technology  because it can only produce and not absorb energy.

Storage is currently limited in its deployment but increasing prices of electricity may prompt further development of mature technologies such as pumped hydroelectric and foster innovation in newer technologies such a hydrogen or grid scale batteries.

Interconnectors currently provide us with the most efficient alternative that helps increase system efficiency by increasing the access to other energy generators.

They also provide additional benefits such as export opportunities for our wind industry, which is good for our balance of payments, as well as access to a wide diversity of generation technologies abroad.

Iceland has geothermal and hydroelectric energy and the first proposal for an interconnector to the UK was made in the 1980s. Norway has hydroelectric power and is widely considered to be a partial solution to the intermittency of the North Sea wind. Spain and North Africa have abundant sources of solar energy that the Germans are currently pursuing.

Finally, our current interconnector capacity to mainland Europe provides us with access to nuclear power and potentially solar power from the south. The national grid has suggested we will be depending on this for our energy security sooner rather than later - further emphasising the need for us to diversify our connections to other markets.

As a first step, the government needs to define what conditions need to be met for interconnectors to contribute to our security of supply. Access to a wide range of markets and technologies appears to be an obvious solution. This will inform interconnection priorities.

The complexities associated with a cross-border planning process are a major barrier to development. The government should be laying the foundations for priority interconnector projects by actively pursuing strategic environmental assessments whilst working with partner nations to do the same.

The European Commission is keen on greater interconnection between member states and neighbouring states. The UK should engage properly with this process, taking advantage of EC funding to promote our priority projects. The Norway-UK interconnector is a perfect example of a common priority project.

Other options exist but need active, committed government policy, if not we may be forced to rely on ever more expensive gas.

Very interesting article. Though the picture that is used to illustrate shale gas development in Wyoming, US looks like the Jonah Field. This is a tight gas field developed in the early 1990s before the technology of slickwater hydraulic fracturing was really developed and refined.

Professor Lawrence Cathles of Cornell University recently took to the air in Pennsylvania to view the impact of shale gas at the Marcellus shale. Which is more illustrative of shale gas development in recent years.

Thanks for the comment and powerpoint. Prof. Lawrence Cathles pictures do help highlight some of the impacts of shale gas extraction quite well. Again, the similarities of with the wind industry appear stricking. We are not talking about huge scarification of the land but many small localised impacts.

For clarification, I used the following site to locate the field: http://frack.skytruth.org/fracking-chemical-database#Subscribe

On this it appears to be called the Stud Horse Butte in Sublette county of Wycoming and appears to have been built in 2011.

 

Prof. Cathles photos show the operations in the main heartland of shale gas production in the US and are a worthy insight. Of course, local communities have legitimate concerns about the localised impacts, as with most energy infrastructure projects.

Thanks for the clarification on the picture. The Jonah Field (predominantly tight gas) is located in Sublette County, Wyoming. The Wyoming State Historical Society's website (link below) documents the history of the Jonah Field. On page 2 you can see that by July 2001 there had already been considerable activity at the field with 300 wells drilled. This was when the industry was still in its infancy. However, new hydraulic fracturing rigs are still being put in place in Sublette County, as your source shows.

Although the website's article is entitled "a natural-gas success story" the images of the impact at the Jonah Field are striking. Due to advances in technology these images are not replicated for shale gas production in Pennsylvania and would not be replicated in Europe.

Again, very interesting article on interconnectors and all-important electricity storage.

In a practical gas turbine, gases are first accelerated in either a centrifugal or axial compressor. These gases are then slowed using a diverging nozzle known as a diffuser; these processes increase the pressure and temperature of the flow. In an ideal system, this is isentropic.

Diversification will reduce the reliance on only Gas as fuel but there are some other steps required like reduction in energy demand. Government can take steps like setting market close time in big cities, it will reduce energy demand. editing pdf files Thanks

From my understanding, both are required, new plants will increasing the amount of electricity generated, but new distribution lines are also required, since these lines have a limit in the amount of electricity they can transmitt.

To fully enjoy the place, it's not enough that you stay in one particular island. An estimate of 1 out of 3 tourists enjoys having multi-island tours especially when they're planning on staying in Hawaii for at least 1 or 2 weeks spending 3-4 days in each island. What makes this trip less tiring is that travelling from one island to another will only take at least 30-minutes in an inter-island flight and the best way to tour each island is by renting a car because unfortunately there is no public transportation here except in Honolulu.    <a href="http://www.multitourist.com/">multitourist</a>

To totally take advantage of the place, it isn't adequate that you simply relax in just one isle. A estimate of just one from 3 tourists relishes having multi-island trips specially when there're intending on vacationing in Hawaii for at least a few days investing 3-4 nights throughout every isle.
