Offshore renewable energy – Accelerating growth with marine geospatial data | UK Hydrographic Office

By 2050, renewables are expected to generate 50% of the world’s electrical power. As we seek more sustainable sources of energy, the sector is continuing to grow driven by increasing customer demand, innovation and cost competitiveness.

When harnessing renewable energy, our oceans play a pivotal role. Offshore wind, wave and tidal energy each offer cleaner alternatives to fossil fuels. In fact, by 2030 the ocean-based renewables sector is expected to grow to a staggering £178 billion.

Currently, the largest source of ocean-based renewables is offshore wind power, expected to become a £1trillion industry by 2040. Today, 90% of offshore wind capacity is installed in Europe, but Asia Pacific is expected to experience large growth by 2050.

Floating wind farms will play a key role in accelerating growth across the globe, enabling energy to be harnessed even in areas of deep water, with higher wind speeds. With the potential to generate 8 times the global electricity demand today, offshore wind will make up an important part of the energy mix for the future.

Tidal and wave energy are also expected to experience large growth by 2030. Predictable ocean flows mean a continuous, dependable source of energy. As this sector steps closer towards becoming commercially viable, it could radically change the renewable energy landscape.

With a global push towards cleaner energy, how can we harness these renewables safely and sustainably? It starts with knowledge of our oceans.

From bathymetry and seabed geology, to information on tides and marine habitats, marine geospatial data can provide a richer understanding of both existing and prospective sites. This data can inform decisions that help improve efficiency, that minimise impact on the marine environment, and that help unlock the full potential of the offshore renewable energy sector.
