Sinclair Knight Merz
Making the future of energy production a reality
Sinclair Knight Merz (SKM) is an engineering, sciences and project delivery company. Founded in Australia it has offices in New Zealand, Europe, the Middle East, South America, and Asia. Its reach is truly wide, but what is very impressive is their capabilities. They are divided into four broad business units, which are Buildings and Infrastructure, Power and Energy, Mining and Metals, and Water and Environment. The cross over in some of these sectors has allowed SKM to develop unique services to their client base.
One of the most forward thinking divisions within the broad range of abilities that SKM has is their Geothermal Energy unit. Here, Dr Stephen Hinchliffe is their Geothermal Development Manager for Australia, and he sees great possibilities for this industry in both Australia and around the world. Dr Hinchliffe has over 18 years of experience in the renewable energy sector and has been working with SKM for almost 10 years. He has extensive experience in both project management and grid connections, which make him ideally suited for his role at SKM. “A significant amount of my work is what you would call strategic consultancy, supporting the development and evaluation of project concepts as well as undertaking the coordination of the development of a given project,” he says.
Bringing all their abilities to the table
“We are a fairly broad based project delivery, engineering and environmental consultancy, one of the areas of particular interest to the company is building sustainable projects,” says Dr Hinchliffe. “The geothermal part of that is an integral part of that company focus. The main centre of excellence – as we call it – for geothermal project development support is in New Zealand,” he says, but points out that they have several offices containing geothermal consultants that allow them to operate internationally.
“We have been for the last 30 years involved in about 50 per cent of all geothermal projects around the globe.” He says that this is because they can manage and work through an entire geothermal project from start to finish. “We can provide a wide suite of services from reservoir identification and development to above ground facilities design and delivery including environmental approval and network connection support,” says Dr Hinchliffe.
They support the entire project implementation process, he says. “As an organisation we are able to take a geothermal project from inception right through to long term operational support which we do in a number of established geothermal projects,” he says. He points out that this means that they are not limited to new projects but are able to support existing ones as they require in service modification to adapt to evolving reservoir conditions. Mid-life refurbishment power plant extensions and general plant operations support is something that they also perform for conventional energy projects, and experience in these projects provides valuable lessons for the geothermal industry. “Project management is a fairly significant part of our business,” Dr Hinchliffe relates. “We have just finished the owners engineering role for a Kenyan geothermal project, the third unit at Olkaria 2 near Lake Naivasha, and are now starting on two new power plants, one on the North East field adjacent to the Olkaria 1 power plant and the second in an area known as the Domes, referred to as Olkaria 4.”
Geothermal Energy: too important to ignore
Dr Hinchliffe sees that geothermal energy is an important aspect of the future of energy supply needs in both Australia and the world. He says that putting a value on carbon is inevitable, but it is not the only solution to the current carbon emission problem. “We need to build the mechanisms to support low carbon emissions projects, and this will be difficult, especially in Australia where renewable projects have to compete with abundant, low cost coal. In some parts of the world high temperature geothermal energy already is competitive but it all depends on the cost of alternative, base load, energy sources,” he says. Whilst putting a price on carbon in Australia will help, more is needed in the short term to support geothermal projects because Australia is pioneering medium temperature resources and has the opportunity to become a world leader in developing appropriate technology for this. Dr Hinchliffe thinks that direct funding support for emerging renewable energy schemes like medium temperature geothermal projects directly is still required in order to demonstrate to the market and investors the viability of such projects. He sees that the future of clean or greener energy production within Australia is dependent on a convergence of carbon free technologies as well as regulated traditional energy sources. The advantage he says with the geothermal route is that many of the skills sets associated with oil and gas exploration and production can be transferred, through synthesis of conventional geothermal energy techniques and knowledge to geothermal energy exploration and production. Also, and unlike other sources of renewable energy, geothermal is not dependant on intermittent energy sources such as weather or tide. It can produce reliable base load power into the grid 24 hours a day, 7 days a week.
“One thing that excites me about geothermal energy in Australia is that it is such a vast energy resource. Geosciences Australia has predicted that there is enough geothermal energy exploitable to power Australia for several thousands of years at the current demands level,” says Dr Hinchliffe. “It is a significant resource, and I would argue that it is too significant to ignore. As such supports should be given to the development of this industry.”
Dr Hinchliffe sees that the role that SKM plays in the development of this industry as important because of their wide ranging abilities in the management and support of other related sectors. “We help geothermal developers bring their projects to fruition, and as a company we are passionate about this role,” he says. He hopes that in the next few years that they will have a hand in creating several geothermal projects of commercial size operating in Australia, and that these will be making a significant contribution to its energy grid and reduction in carbon emissions.
