The climate change committee concluded in 2019 that an energy transition to net zero in the UK by 2050 is affordable, achievable but challenging. Overall Green House Gas (GHG) emissions for power generation dominated by CO2 are only 1/3 of 1990 levels. This was achieved by phasing-out coal-fired power stations, relying on gas and increase renewable penetration. The main source of renewable energy in the UK is offshore wind energy. The UK is now an offshore wind global leader, with an aspiration of reaching 75GW installed generation by 2050. Therefore, it will play a vital role in the future energy transition. With all such efforts toward net zero, UK offshore Oil and Gas (O&G) installations are facing the following challenges:

-Oil/gas production generates around 14.6 million tonnes of CO2 emissions per annum

-Open cycle gas turbines are responsible for 75% of such emissions

-Direct access to onshore grid is not economically feasible for the majority of offshore installations

-During 2019, operators paid up to £25.5/tonne for CO2 released

-Most likely, the CO2 tax prices will be increased in future

In this webinar, the University of Strathclyde will discuss different electrification options for the UKCS. This is part of the OGTC funded project entitled ‘Realising the value of offshore grid access for small pools’. It is an overview feasibility study to discover reliable, affordable and low-carbon power grid architectures for all of the UKCS. Five potential power architectures have been proposed, which can be deployed and mimicked along the UKCS to reduce dependency on open cycle gas turbines:

-Architecture 1: Utilise the installation of a local floating wind farm feeding a network of isolated oil/gas platforms

-Architecture 2: Create a power-hub fed from large-scale wind farms, therefore, access to clean energy made possible

-Architecture 3: Create a network of offshore wind power, onshore grid power and oil/gas platforms. The power direction and amount is fully controlled and flexible.

-Architecture 4: Provide the possibility of connecting remote oil/gas platforms to other EU countries’ grid – e.g Norway

-Architecture 5: Adopt taping AC power to feed small facilities nearby existing offshore wind farm substations
