Siemens has received an order for components for an energy recovery facility in Hull, Yorkshire.

Being supplied are an SST-600 Enhanced Platform industrial steam turbine, a SGen5-100A generator as well as the SPPA-T3000 instrumentation and control system. Siemens will also supply a 35-MVA power transformer.

The client for the steam turbine set including instrumentation and control system is the global engineering and construction company, M+W Group which is building the plant for the independent power producer Energy Works.

The Hull energy recovery facility is expected to begin supplying energy efficiently in March 2018 and producing enough electricity to power the equivalent of about 43,000 homes.

Waste that would normally be destined for landfill sites is becoming a valuable fuel for generating power. Over 250 million tons of rubbish is currently used as fuel to produce energy every year worldwide. Modern plants are used to dispose of processed waste and generate electricity, thereby reducing the environmental impact.

An advanced gasification process is used by Energy Works to generate super-heated steam. A steam turbine uses this to generate electricity, saving fossil fuels such as coal and oil. On average, one litre of oil contains the same amount of energy as four kilograms of waste. The efficient SST-600 steam turbine has an electrical capacity of 30 megawatts. Siemens will manufacture the steam turbine in Görlitz and the generator in Berlin, both in Germany.

“With the Enhanced Platform Design the customer is able to operate its plant with a maximum of efficiency. Thereby the market requirements can be fulfilled with highest flexibility and reliability,” explained Olaf Kreyenberg, sales head of the Power and Gas Division for the Europe and CIS Region. “In talks with the customer, we were able to address their requirements at an early stage and develop a suitable business scenario.”

Siemens' Enhanced Platform Design features higher efficiency rates achieved by utilizing the highly efficient blading system long proven in large-scale power generating units, an optimized steam path, and an advanced casing design.

“The steam turbine selection was critical in achieving the high efficiency energy recovery performance required. Early collaboration between our respective expert process engineers optimized the design and value for this flagship project whilst providing a solid foundation for the delivery and commissioning phase. The Siemens turbine met these key M+W Group criteria along with the confidence that comes from working with a highly respected international engineering company,” said Nick Dawber of M+W Group (UK).

Matthew Knight, Director of Energy Strategy for Siemens plc says, “We are delighted to be involved in the Hull Energy Recovery Project. The world of energy is changing and once again Hull and Siemens are taking a lead; bringing secure, affordable and sustainable energy generation to the city. All countries need a balanced mix of electricity generation. Projects like this, alongside the giant wind turbines we will be making nearby, are a vital part of Britain’s energy future.”

About Energy Works

Energy Works will be the largest facility of its type in the UK and will generate renewable electricity from domestic and commercial refuse-derived fuel, using an innovative energy recovery process called fluidised bed gasification.

The 25MW net power output facility is being built on an eight-acre riverside site in Cleveland Street, Hull, and is due to be operational by March 2018.

It will generate sufficient electricity to power 43,000 homes and stimulate the economy, through the creation of jobs during the construction phase and around 25 permanent positions once Energy Works is operational. It will also regenerate a long-disused brownfield site.

The development is being delivered under an engineer, procure and construct (EPC) contract by global engineering and construction company M+W Group, a market leader in the delivery of state-of-the-art energy from waste facilities.

Hull-based specialist engineering business Spencer Group forms part of the delivery team building Energy Works. Spencer steered the Energy Works project from its conception in 2010, making a multi-million pounds investment to develop the scheme into its delivery phase.

Shareholders of Energy Works (Hull) Ltd are Bioenergy Infrastructure Group (BIG), an independent power producer established to invest in the construction of new biomass and energy from waste (EfW) plants in the UK; Noy Fund, an investment group based in Israel focused on major infrastructure and energy projects; Hancock Natural Resource Group (HNRG), a long-established timber, agriculture, and renewable energy investment management company; and Spencer Group.
