Wave Power

George Eustice Excerpts

Tuesday 15th February 2011 Westminster Hall

[George Eustice (Camborne and Redruth) (Con)]

It is a pleasure to serve under your chairmanship, Mr Hollobone, in this important debate on the funding of wave-power innovation and technology.

Let me start by saying a little about the potential of this new industry. About 25% of all wave and tidal technology development is going on in this country. Our marine resource is second to none, and that is nowhere truer than in the south-west of England. The extraordinary resource around our coastline is backed up by lots of the skills and expertise that we need to develop the technology. The Carbon Trust has estimated that wave power could eventually meet 15% to 20% of our current power needs and that it might produce enough electricity over time to power 11 million homes. Furthermore, with the extraordinary development of this new energy resource comes a lot of economic potential. It is estimated that the industry could be worth £2 billion by 2050 and that it could create more than 16,000 jobs. Some estimates suggest that the wave and tidal power industries together might employ 10,000 by as early as 2020.

My constituency is home to the wave hub project, which is the first project of its kind anywhere in the world. It is the first time we will have a commercial-scale facility to test arrays of wave-power devices at deep-water locations. The project consists of a long cable 16 km off our coast at Hayle, with a plug anchored on the sea bed to take up to four arrays of devices for testing. Currently, the maximum power produced by each device is 4 or 5 MW, but it will be possible to expand capacity over time so that the wave hub could feed no less than 50 MW into the network. One company has already signed up to plug into the wave-power device. Ocean Power Technologies will test a commercial-scale version of its PowerBuoy system, which is one of the leading systems being developed.

My constituency is also home to the Peninsula Research Institute for Marine Renewable Energy, or PRIMaRE, to give it its short name. The institute is based at the Tremough campus near Falmouth. At the institute, academics from Exeter university and the Camborne School of Mines are doing a lot of important work, which is needed to support the development of wave-power technology. I visited last summer to see some of the work that is being done on moorings. The Cornish coast is famous for wrecking boats, and the sea can be quite choppy at times, so getting the strength of moorings for wave-powered devices just right is an important part of the development of wave power. PRIMaRE is also doing a lot of tests on new devices to see how each device works in commercial situations.

That brings me to a point about the importance of developing and funding technology innovation. The marine renewables deployment fund will be phased out in March 2011, although according to those in the industry, this £40 million fund was never very satisfactory. It was notoriously difficult to access; in fact, I am not sure whether anybody ever successfully accessed it. The reason is that one of the criteria stipulated that a device had to have been actively and successfully working in commercial situations for at least three months before someone was eligible to apply for a grant. However, the key thing about wave-power technologies is that developers need support before that point; they need support before they get to the stage of keeping a device in the water for three months, not after they have achieved that extraordinary feat. Some estimates suggest that the cost of developing and deploying a commercial-scale device is in the region of £30 million, so developers need support much earlier in the process.

Some improvements were made under the marine renewables deployment fund, which was deliberately designed to come in a bit earlier. However, we now need to think carefully about how we move from the proving stage—testing small devices at the European Marine Energy Centre—to the stage of developing wave power on a much bigger scale.

[Andrew George (St Ives) (LD)]

My hon. Friend is making a good case. In the previous Parliament, my constituency included the Hayle area, so I was involved in the development of the excellent project he is talking about. However, does he agree—I think he is coming to this—that if the project, which enjoys perfect conditions, is to become a commercial success, we need public sector support, such as renewables obligation certificates or other means, to bridge the gap between where it is now and where it needs to be?

[George Eustice]

Yes, I absolutely agree. Although the wave hub technically comes ashore at Hayle, my hon. Friend has told us once before that it is actually in St Ives waters, and we have both had discussions with representatives of the fishing industry, who have concerns about where the wave hub is located. However, I absolutely agree with my hon. Friend, and I was coming to the point he raises.

The Government have announced a review with the Technology Strategy Board. They have also announced the new idea of technology innovation centres. Those involved with the wave hub and the PRIMaRE institute at Tremough are keen to develop a TIC for offshore renewables in the south-west. What I want from the Minister today is some idea of the criteria that will be applied. We know that a technology innovation needs assessment—TINA, in the jargon of the trade—is being carried out for projects that want to put themselves forward for a TIC. I was recently pleased to hear the Minister repeat his pledge about trying to develop a marine energy park in the south-west, and there is no better place for that than Hayle. A lot of infrastructure improvements are being carried out on the north quay, and a small marine business park will be located near the wave hub project.

I am keen, however, to understand the criteria that will be applied. I am not a big fan of ring-fencing these budgets and pots of money. Some in the industry say that we should make x amount of the £200 million available for wave-power development, but it is much more important to apply the right criteria to determine where to allocate the funds. The marine renewables deployment fund failed because we were far too risk averse. The whole reason for having public subsidy and public investment in these areas is to bridge the gap between risk and potential. When it comes to wave power, we have extraordinary potential, with a source of energy that could meet 15% or 20% of our energy needs. However, there is also a large risk in that it is much harder to develop devices to use out at sea in difficult conditions. As I said, it can cost up to £30 million to develop these technologies. The Government’s role should be to come in and bridge that divide between risk and potential.

The second key point about the criteria is that they must look at what stage the development of the technology has reached. Those involved in wave power have just gone past the phase of testing devices in a tank in the laboratory and have moved to testing commercial-scale arrays, so the industry really needs some additional funds to help it make the next step. A lot of the other renewables industries that will be competing for the same funds are quite a bit further along the development road, and we should be making much tougher demands on them so that they start getting private sector investment. We should also remember that providing public sector investment can unleash a lot of additional private sector investment. The £100 million that the Government have already invested in wave power has brought in an additional £200 million of private sector investment. There is private sector money, but those concerned need to know that there is a commitment to develop things to the next stage.

Finally, geography is another factor to take into account in relation to the capacity to develop an industry, and I want to say a little about ROCs. In Scotland five ROCs per megawatt-hour are paid at the moment for wave power that is generated, but there is not the capacity on the grid to develop an industry there. We need to avoid a situation in which all the development of the industry takes place in Scotland, but in a few years we find that there is insufficient capacity in the grid to capitalise on the industry properly. It would be far better to develop the industry in the south-west where there is capacity on the grid to upscale and expand the industry.

I believe strongly that in addition to the right technology push we need the right support framework to create the pull conditions to enable the industry to go beyond the development stage. There is no doubt that the answer is to increase the number of ROCs that we pay on the commercial devices to five ROCs per megawatt-hour, so that we match Scotland. That would give a level playing field.

[Andrew George]

My hon. Friend has got to the nub of the biggest hurdle to taking the project forward. As the Government are reviewing the ROC regime it is clear that some intense negotiation is needed between the UK Government and the Scottish Executive, to give sense and sanity, and an even playing field across the border.

[George Eustice]

I agree with my hon. Friend. There was quite a bit of criticism of the decision by Scotland to go unilaterally for the five-ROC regime. Others in the industry say that perhaps five are not needed and perhaps three or four would be acceptable, but we need that level playing field, so that the people developing the technology can make rational judgments rather than just chasing those paying the highest amount of money.

We are clearly entering an era of energy needs in which there is no magic bullet. We shall need many different sources of energy to come on stream. The Minister once told me that wherever he goes, and whatever conference he attends, people say “This is the magic industry that is the future” whether it be biomass, anaerobic digestion, nuclear or something else. The truth is that we shall probably need a range of sources to supply our energy needs in the future. It is clear that wave power could be one of those important sources, but only if we are willing to back it to the next stage, to get it to a commercially viable situation.

[Mr Philip Hollobone (in the Chair)]

With the permission of the hon. Member for Camborne and Redruth (George Eustice) and the Minister, I invite Mr Shannon to make a contribution, but I want to call the Minister at 1.45.
