UNTAPPED coal seams which could supply the entire energy needs of Swansea for the next 30 years are to be investigated deep under Swansea Bay.

A British/US company has been given permission by the UK Coal Authority to use the very latest techniques in offshore drilling technology to probe beneath the waves.

Clean Coal Ltd will investigate the potential for the underground gasification of the coal seams to produce a gas that can be used in electricity power generation, heating and fuel.

If the investigations over the next 12-18 months prove to be successful, the gasification of the coal reserves and associated infrastructure would, according to the company, provide Wales and the whole of the UK with a significant new and long-term energy supply.

"Studies undertaken by Clean Coal Ltd indicate that the coal reserves in this licence area suitable for underground gasification (estimated to be around 200 million tonnes) could produce the entire energy requirement of Swansea for at least thirty years," said a company spokesman.

"This would be the first time that gasification of underground coal has featured in the UK energy market."

Clean Coal specialises in underground coal gasification and is developing projects in other parts of the world.

It has identified Swansea Bay and four other offshore sites in England and Scotland to be surveyed in order to establish their suitability and energy potential.

The offshore underground investigations in Swansea Bay will include seismic and borehole surveys of an area of nearly 80km² at depths of between 800 and 1200 metres.

The surveys will not have any detrimental impact on the marine life, shipping nor other users of Swansea Bay, according to Clean Coal.

Rohan Courtney, chairman of Clean Coal, said: "Recent developments in directional drilling technology and the growing need for new, secure and environmentally benign sources of energy means that underground coal gasification now merits serious investigation.

"This is an exciting and commercially viable development which can bring significant long-term benefit to South Wales.

"We plan to start our investigations in the first half of next year and will be hosting a public exhibition before we start our work. With the work being carried out deep below the surface, our work should largely go unnoticed but we are keen to share our plans beforehand, explain the process of underground coal gasification and outline the potential benefits to the local economy. It's an exciting development."

Underground coal gasification (UCG) is a method of converting deep seam coals into a combustible gas used for power generation, industrial heating, or the manufacture of hydrogen, syngas, chemical feedstocks, jet fuel or diesel fuel.

The gasification of coal in-situ is achieved by drilling boreholes into the coal and injecting water/air or water/oxygen mixtures.

The other underground sites being investigated are Canonbie in Dumfrieshire, Cromer in Norfolk, Humberside and Sunderland.

    “Jim.
    I don't know. That is why I posted my previous comments on this thread in the hope that others will take and interest in the environmental and safety issues etc.”

    “Paul, West Cross.

    OK, let's forget land ownership for a minute, and look at the basic rationale for this. This development will have to feed some kind of power station. So answer two basic questions for me;

    1) Where will the power station be sited?

    2) What's the basic need for it?”

    “Jim Dunckley, Gorseinon
    Most of the comments, on this thread, including your own, are about ownership and profit.
    Please refer to my posting on 10-Dec-2009 10:47 and you will get info on the process.
    If you read Michael Green's report, you will see a photo of the Angren UCG Power Station in Uzbekistan that I mentioned on 09-Dec-2009 16:33.
    Best wishes from the comfy Mumbles enclave.”

    “It's interesesting that a lot of the pro commmentators on here are posting from comfy enclaves like Sketty, Mumbles etc.

    They know full well that if a company sticks a drilling rig in front of mumbles, there will be uproar, and they wil be first in the queue to join the NIMBY brigade.

    This development will turn coal into gas, which means it will serve all the new power stations in Baglan etc. For this reason it'll probably be situated on the Eastside of Swansea, well away from Costa del Mumbles et al.

    Not so much a case of Jack, as "I'm alright Jack".”

    “Of course we want quality jobs in Swansea. But we want the benefit of our resources for us this time. John Jenkins you might have a Welsh name but your xenophobic and patronising attitude is exactly the type I experienced whilst working in London over 25 years ago. Just because you go to work on the underground it doesn't mean you are superior or harder working than us. I wonder if the Lehman Brothers ex employees would be a keen on foreign companies as you are.”

    “It is sometimes amazing how xenophobic the EP community is most of the time. I can not believe that in 2009 people are still complaining about robber barons from centuries ago and complaining about the money leaving Swansea and travelling hundreds of miles away across an imaginary border. As someone who has been personally involved in the construction and operation of power stations throughout the world, I know first hand of the benefits that a development of this kind will bring to a local community. Firstly, you have the direct impact of job creation to service the construction, operation and maintenance of the development. For each job that is created during this phase four jobs are created in the area in the service industry. You also have improved transport and infrastructure links to support the development (all paid for by the developing company). Finally you have possible local incentives such as royalty or equity payments that need to be discussed by the WAG and the developer, and these payments would be paid directly to the local area. I am often glad that major decisions in this country are made by politicians and not the general population or else we would still be in the dark ages.”

    “Achmeds, Uncle - businesses don't have to borrow from the bank in order to expand. They can get money from investors. I myself have invested in a few small companies. The same is true of individuals. If you have a great business idea and can make it work, I would consider investing. If you want something, there is always a way to make it work.”

    “Matthew, Swansea - you said you doubted that Swansea will see any economic benefit. Well it si bound to. If this project goes ahead it will need workers, hopefully from this area. Even if workers come from outside Wales, they will be living here and spending money here. So that's an economic benefit. Local landlords, supermarkets, cafes, shops, etc. will all benefit. I for one think it's great for Swansea. We need more companies like this willing to invest in the area. It would be great if local companies invested but they don't seem able to.”

    “Of course certain people will profit from this. It wasnt so long ago that a certain landowner got a lot of money just because there was a need to have a bridge over the river Tawe. Regarding the offshore riches I dont know who would own it. The way things are with the banks now, its easy to invest if you have the money to do so but not so easy if you havent seeing they are making things more difficult each day for Joe Public to get mortgages etc. along with smaller businesses not being able to get a loan to enlarge their company. So yes in my eyes the gap between those with money and those who havent is getting bigger and bigger.”

    “A company explores for coal - response on this website is that we won't benefit.

    £2.5 million restaurant opens in Marina - response is that it's too expensive and we don't want it.

    Bar opens in Wind Stree and creates 60 jobs - mostly negative response.

    New shops open on David Evans site - response is that shops are too expensive.

    What is wrong with you people? What exactly do you want in Swansea? Nothing is ever good enough for you. You all say you want things to happen here but when it does you don't want it, it's not good enough, it's too expensive.

    Get a life.”
