Sustainable Islands

Sustainable Islands

We understand that island states face unique obstacles. Challenges for island states range from decreasing historical dependencies on imported fossil fuels, the need for strong resiliency of island systems in light of extreme weather and other threats, diversification of island economies, and the need to transition to sustainable systems. In response to these challenges, islands around the world have developed and implemented innovative solutions.
Ricardo Energy & Environment works with island states to achieve sustainable systems that support local island economies. Clean energy and resource efficiency can provide island states with improved energy security and independence, cost reductions for businesses and consumers, greater resiliency, support local economic development and combat climate change and negative environmental impacts.
Solutions for islands can be limited by specific conditions and capabilities on the island, and therefore we value partnership with local stakeholders. We believe those living on the island have an essential role in determining the best solutions.
Ricardo Energy & Environment offers integrated cross-sector services for islands, which include electricity infrastructure, local energy, transport, waste and resource management.

Project highlights

Bermuda Integrated Resource Plan
Project to develop a new 20- year Integrated Resource Plan (IRP) for generation expansion in Bermuda. Ricardo used in- house system planning tools tailored to island systems and coordinated network studies. We demonstrated the least-cost scenario involves significant renewable energy penetration over the next decade. In the new IRP, 85% of energy would come from renewable sources by 2035 and more than 3 million tons of carbon emissions would be avoided. Read more

Isle of Wight Hydrogen Opportunities
Development of solar PV schemes on the Isle of Wight are constrained by the limited capacity on the subsea cables to the mainland. This reduces income and the potential to expand solar PV capacity. We are investigating the potential to produce hydrogen from solar PV, for use in transport. Two options are being considered, road vehicles (cars & vans) and marine (auxiliary power for ferries).

Ascension Island Waste Strategy
Ricardo provided support to Ascension Island to produce a waste strategy for the island. The island is one of the remotest in the world and relies heavily upon imported goods and employs basic waste management practices. As such, markets for products such as compost, digestate and recyclable materials is limited. We reviewed the demographics, industry and waste production on the island and investigated a range of technologies, alongside their costs and suitability for use on the island to manage its waste.

Pacific Islands Renewable Energy Integration
Project to enhance the ability of power utilities in the Pacific region incorporate and manage variable renewable energy. We provided services for analysis of power system impacts of variable renewable energy and grid integration studies; assessment of energy storage applications and needs for SCADA and EMS systems; preparation or improvement of transmission and distribution grid codes; and developing capacity at national utilities on renewable energy integration.


Technical case study:

Renewable energy options towards net zero for a remote island
This technical case study outlines the comprehensive approach we have taken to assess a remote island's available renewable energy options, and to transition its transport sector to electric vehicles. The overall aim was to support the island government in its ambition to achieve its long term net zero emisisons target by 2050.  Read more.
