Thor Cogeneration is a planned gas-fired cogeneration plant, which is to be built on Seal Sands near Billingham, in County Durham, North East England.

Natural gas fossil fuel

Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas.

Cogeneration simultaneous generation of electricity, and/or heating, or cooling, or industrial chemicals

Cogeneration or combined heat and power (CHP) is the use of a heat engine or power station to generate electricity and useful heat at the same time. Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector. The terms cogeneration and trigeneration can be also applied to the power systems generating simultaneously electricity, heat, and industrial chemicals – e.g., syngas or pure hydrogen.

Seal Sands is a 294.37 hectare biological Site of Special Scientific Interest in Cleveland, England, notified in 1966.



On 19 January 2007, newly established business venture Thor Cogeneration, a subsidiary of Teesside-based PX Group, announced plans for a new power station on Teesside. [1] The station is proposed as a 1,020 megawatt (MW) combined heat and power combined cycle gas turbine plant. [2] Stockton Borough Council gave their approval for the station in April 2007. The station's licence for the generation of electricity was also granted later in 2007. [3] On 28 August 2008, government approval for the station to be built was granted by Energy minister Malcolm Wicks. [4] Construction is expected to begin in 2009, with operations predicted for early in 2012. [3]

Teesside Place in England

Teesside is a conurbation around Middlesbrough on the River Tees in North East England which also includes Billingham, Redcar, Stockton-on-Tees and Thornaby. It is a centre for heavy industry, although the number of people employed has declined. Traditional industries, primarily steelmaking and chemical manufacture, have been replaced to a large extent by high technology activities, science development and service sector roles.

Proposed specification

The station will use two gas-fired generators, with excess heat being used to make steam to drive a further generator. [3] Electricity generated will be distributed to the National Grid. As well as generating electricity, the station will provide heat to the nearby, SABIC operated North Tees Works oil refinery, in the form of steam. Natural gas, the station's fuel, will be supplied to the station by a pipeline, with a short connection to an existing pipeline to the north. [2] The station will require 20% less gas per MW generated than current operating gas-fired stations. [4]

SABIC is a Saudi diversified manufacturing company, active in petrochemicals, chemicals, industrial polymers, fertilizers, and metals. It is the largest public company in the Middle East and Saudi Arabia as listed in Tadawul. 70% of SABIC's shares are owned by Saudi Aramco. Private shareholders are from Saudi Arabia and other countries of the six-nation Gulf Cooperation Council (GCC).

Oil refinery industrial process plant where crude oil is processed and refined into more useful products

An oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Petrochemicals feed stock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha.

The station is expected to be able to achieve a 58% efficiency rating by using the latest gas turbine technology. [2] It will create 60% less carbon emissions than current coal-fired power stations. [4] It will be cooled by using an air cooled condenser, avoiding the need to extract from or discharge water into the nearby River Tees. 1,000 people will be employed during the construction and 60 will be employed when the station is operational.

Power station facility generating electric power

A power station, also referred to as a power plant or powerhouse and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Most power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Cleaner sources include nuclear power, biogas and an increasing use of renewables such as solar, wind, wave and hydroelectric.

Combined cycle power plant type of power station

In electric power generation a combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy to drive electrical generators. The principle is that after completing its cycle, the temperature of the working fluid in the system is still high enough that a second subsequent heat engine extracts energy from the heat that the first engine produced. By generating electricity from multiple streams of work, the overall net efficiency of the system may be increased by 50–60%. That is, from an overall efficiency of say 34%, to possibly an overall efficiency of 62%, 84% of theoretical efficiency

Thermal power station power plant in which heat energy is converted to electric power

A thermal power station is a power station in which heat energy is converted to electric power. In most of the places in the world the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due to the different heat sources; fossil fuel dominates here, although nuclear heat energy; solar heat energy, biofuels and waste incineration are also used. Some prefer to use the term energy center because such facilities convert forms of heat energy into electrical energy. Certain thermal power stations are also designed to produce heat energy for industrial purposes, or district heating, or desalination of water, in addition to generating electrical power.

Teesside power station

Teesside Power Station is a former gas-fired power station, in Redcar & Cleveland, England. Situated near the Wilton chemical complex, the station had combined cycle gas turbines (CCGTs) and open cycle gas turbines (OCGTs), however in 2011 the operation of the CCGT part of the station was suspended, and in 2013 the owners announced its closure and plans to demolish it. Prior to the suspension, the station had a generating capacity of 1875 megawatts (MW), making it the largest of any CCGT power station in Europe. The station could meet almost 3% of the electricity demand for England, Wales and Scotland. Opened in 1993, the station was initially operated by Enron but moved into the hands of PX Ltd after the Enron scandal of 2001, before being bought by Gaz de France and Suez in 2008. The station also worked as a cogeneration plant, providing steam for the Wilton complex.

Gas-fired power plant One or more generators which convert natural gas into electricity

A gas-fired power plant or gas-fired power station or natural gas power plant is a thermal power station which burns natural gas to generate electricity. Natural gas power stations generate a quarter of world electricity and a significant part of global greenhouse gas emissions and thus global warming. However they can provide seasonal dispatchable generation to balance variable renewable energy where hydropower or interconnectors are not available.
