The Caribbean benefits from cheap solutions for renewable energy, reducing the costs of the energy system, reducing climate risks and stimulating a clean energy transition. With solar PV as the cornerstone technology, the region is ready to switch to a solar-x-economy, which uses the abundant renewable agents to reach carbon neutrality.
The Caribbean stands for considerable energy leases, because it is highly dependent on fossil fuels and loaded by high energy costs. These costs have contributed to macro-economic imbalances, the undermining of competitiveness and the hindering of growth as a result of an excessive dependence on expensive imported petroleum products. New research by Lut University Outlines a strategic path for the Caribbean to reach carbon neutrality by 2050, with an emphasis on the need for high electrification and renewable energy sources. The research emphasizes the role of floating solar PV, e-fuel import, grid building and the early decaronization of the energy transition. The research offers unique perspectives on how the region can switch to very high shares of renewable energy and integrate strategically advanced technologies to build a sustainable, low -carbon future. The research is split into two publications entitled “An analysis of multi-sector, multi-node and multi-scenario energy system for the Caribbean with a focus on the role of offshore floating photovoltaic“Published in Reviews for sustainable and sustainable energy and entitled “The energy system of the Caribbean of the Caribbean: emphasize the import of e-fuel, grid integration and accelerated transition“Published in Not renewable power generation.
The analysis reveals a clear shift to high electrification, reducing the dependence on fossil fuels. Solar PV is expected to dominate, accounting for 67-94% of the total electricity generation, with wind 6-30% contributing. The generation of solar PV consists of 12-13% Prosumer PV, 28-81% onshore land mounted PV and 1-45% offshore floating PV. This transition is central to the transformation of the region into one Solar-X-economyWhere solar energy feeds electricity networks and drives clean fuel production and industrial processes. The solar-x-economy is a special case of the general power-to-x-economy that describes energy systems that are predominantly based on electricity for all kinds of energy demand in all energy sectors. The solar-x-economy model offers a blueprint for others Tropical Island Nations Faced with similar challenges and also on the way to very high shares of renewable energy.
Solar energy emerges as a dominant power, driven by the excellent sun sources of the Caribbean and the improvement of economic feasibility, in accordance with earlier findings for the Energy transition from Puerto Rico. In the solar-x-economy, solar PV will generate electricity and contribute to electricity-based e-Brandse and E-chemical production, promoting energy breach and economic growth. Supported by wind energy, hydropower and geothermal sources, will start this renewable link and tackle and create climate change New industries and opportunities for work.

Electrification is crucial for low -carbon road transport, with the transition from combustion engines to electric vehicles that prove very efficient solutions. However, challenges continue to exist in marine and air transport, which require solutions such as e-hydrogen, e-cerosene or biofuels. The Caribbean can achieve sustainable industrialization and a diversified economy by using its cheap renewable energy sources for complete low -carbon poor due to direct and indirect electrification. The power-to-x approach makes it possible Deep carbon -poor from difficult to keep sectors. These studies emphasize the importance of integrating storage technologies to tackle the variability of renewable energy and to guarantee a stable and reliable energy supply in all sectors, including those related to the power-to-x framework. Similar results were found for the similar case of storage as the most important element in the Power-to-X-economy in Hawaii.
Storage technologies such as batteries, hydrogen and methane storage are essential for balancing variability in generating renewable electricity. Batteries offer daily flexibility, hydrogen storage offers buffer capacity for longer -term needs and methane storage performs seasonal demand variations. Vehicle-to-grid technologies Help in managing demand variations, improving overall flexibility and resilience of the energy system of the Caribbean. These technologies are of vital importance for maintaining the reliability of the solar to-X-economy.
EMPort from E-Fuel is a crucial part of the energy transition of the Caribbean. The limited land area underlines their importance for developing the infrastructure that is needed to reach full carbon in all energy sectors, in particular on smaller islands. However, the import of e-Hydrogen is considered unfeasible due to technical challenges and the high costs related to Shipping liquid e-hydrogen. E-fuel input can lower land use and system costs by 7-16%, while the fuel supply and the electricity trade reduce by a maximum of 70% by 2050. The import of e-fuels reduces the use of local resources, shifting competitiveness and investment requirements for exporting hubs. However, the extra flexibility provided by Power-to-X processes is lost. Nevertheless, e-fuel import offers a strategic opportunity for archipelagos to reduce dependence on fossil fuels and to support economic growth. These studies emphasize that the transition from the Caribbean to carbon neutrality is feasible without importing e-fuel, by improving indigenous renewable energy sources, which enhances the capacity of the region to achieve the goals of the carbon in accordance with the findings of a Previous study on Puerto Rico.
Research promotes local and international perspectives on early decaronization for archipel countries. By using renewable energy technologies, such as PV, wind energy and batteries of solar energy, early action can significantly reduce emissions and transition costs to a low-carbon economy. Although accelerated transitions entail 3-12% higher costs than full defossilization by 2050, the long-term environment and economic benefits outweigh these short-term costs, which means that immediate action insisting to prevent higher future costs.
Grid -Interconnection plays a crucial role in enabling the energy transition of the Caribbean and offers considerable cost savings. The study shows that interconnected gratings can lower the system costs by 11%, can lower the empty costs of electricity by 14%and lower CO2 Emissions with 4%. Interconnections improve system reliability and flexibility, allowing islands to share energy sources, reduce dependence on fossil fuels and optimize renewable electricity generation. Raster integration further improves system efficiency, making renewable energy paths 7-24% cheaper compared to alternatives to fossil fuels. With grid sub -buildings, the Caribbean can maximize the use of its renewable energy sources, guaranteeing lower costs and greater energy security.
The research concludes that adopting renewable energy considerably lowers the costs of the energy system. The PV-Battery Hybrid solution emerges as the most economic option for the Caribbean, and the possibility of this hybrid configuration that dominates the future energy system, is also displayed in Earlier literature. In optimum policy scenarios, the level of electricity and simultaneous costs of final energy is expected to be 12-37% and 4-30% lower than alternatives by 2050. This shows that renewable energy-based routes are more cost-competitive than traditional fossil fuel options. The integration of PV-driven solutions for solar energy into a solar-x-X-economy offers both environmental benefits and substantial economic opportunities.
Looking ahead, the Energy Fair of the Caribbean area will be prominent on solar PV, wind energy, batteries, electrolyzers and other power-to-x technologies, which stimulates the defossilization of the region. Dit onderzoek onderstreept de cruciale rol van goedkope hernieuwbare elektriciteit, energieopslag en elektrificatie bij het opzetten van een duurzaam energiekader, met een duidelijk traject naar koolstofneutraliteit tegen 2050.
