Guinea-Bissau’s energy mix is characterized by an extreme reliance on traditional biomass for total energy consumption and imported fossil fuels for its limited electricity generation.

Oil Products (15%): Entirely imported as refined products (diesel, gasoline, kerosene); the country has no indigenous production or refineries. Electricity (1%): Represents a tiny fraction of the total fuel share in final consumption. The country increasingly relies on the OMVG interconnection to import hydroelectricity from neighboring Guinea and Senegal via the West African Power Pool (WAPP).

Guinea-Bissau is positioning itself for a green hydrogen future by adopting the ECOWAS (Economic Community of West African States) Green Hydrogen Policy and Strategy Framework, which targets significant production capacities by 2030 and 2050. Pilot projects are emerging, such as plans to utilize solar power and electrolysis to serve the Bolama region. The broader ECOWAS strategy aims for 0.5 million tons of green hydrogen production by 2030, with a major scale-up planned by 2050.

As of 2026 there is no information indicating that Guinea-Bissau is producing green hydrogen by electrolysis of seawater.

Greece’s energy mix is currently undergoing a rapid transition from a heavy reliance on domestic lignite (brown coal) toward renewable energy and natural gas. In 2024, clean energy (renewables and large hydro) met 50.5% of the country’s electricity demand.

Wind & Solar accounted for approximately 44.4% of demand in 2024. Solar PV capacity specifically reached 9.6 GW by the end of 2024, doubling in just two years. Natural Gas provided 37.5% of demand.

The updated National Energy and Climate Plan aims for renewables to cover 75% of electricity generation by 2030 and 95.6% by 2035.

Greece is rapidly positioning itself as a key European green hydrogen hub, targeting 1.7 GW of electrolysis capacity by 2030 and 30.6 GW by 2050 to decarbonize heavy industry and transport. Backed by significant solar and wind resources, the nation enacted its first dedicated hydrogen law in July 2025 (Law 5251/2025) to regulate production, transport, and storage, including a 25-year Hydrogen Producer Certificate. Hellenic Hydrogen, a joint venture, is developing a 100 MW electrolyzer in Northern Greece, while the H2 CRETE Valley Project focuses on green H2 and ammonia production.

Ghana’s energy mix is currently dominated by thermal power (primarily natural gas) and hydropower, which together account for over 98% of electricity generation. As of 2025, the country is actively expanding its renewable energy capacity, aiming to increase the share of non-hydro renewables from approximately 2% to 14%.

Ghana is rapidly positioning itself as a hub for green hydrogen in West Africa, driven by its significant solar and wind potential, with the first pilot system inaugurated in Tema in February 2025. This initiative aims to produce sustainable energy through electrolysis, supporting decarbonization efforts and energy security. Key developments include international partnerships (e.g., Germany), feasibility studies for hydrogen valleys, and a focus on using green hydrogen for local industrial applications.

On February 20, 2025, Ghana commissioned its first green hydrogen production system at the Don Bosco Solar and Renewable Energy Centre in Tema, in partnership with the University of Applied Sciences of Bochum and other German partners.

In 2024–2025, Germany’s energy mix is transitioning toward renewables, which constitute over 50% of electricity generation, yet fossils (oil and gas) still dominate over 75% of primary energy consumption. Following the April 2023 nuclear phase-out, wind remains the leading power source, followed by solar, coal, and natural gas, with a 2045 carbon neutrality target.

Germany is positioning itself as a global leader in the green hydrogen economy, recently shifting its policy to focus on rapid infrastructure development and international imports to meet a projected demand of 95–130 TWh by 2030. Germany aims to reach 10 GW of domestic electrolyzer capacity by 2030, a target doubled from its original 2020 strategy. The Hydrogen Acceleration Act, approved in October 2025, designates hydrogen projects as being of “overriding public interest,” intended to slash permitting times and fast-track infrastructure.

Germany has embraced the H2Global Initiative, a flagship auction mechanism that provides subsidies to bridge the price gap between expensive green hydrogen imports and what domestic industries can pay.

Because domestic production will only cover a fraction of its needs, Germany has established a robust outward-oriented strategy. It has active agreements with several countries, including Australia, Chile, Morocco, and Finland.

Key projects include RWE, currently commissioning of Europe’s largest green hydrogen plants in Germany; EWE, constructing a 320 electrolyzer in Emden and converting gas storage facilities for hydrogen; GASCADE Leading work on the HYLU pipeline to connect northern production to the grid.

German firms face stiff competition from China, which currently controls nearly 60% of global electrolyzer manufacturing capacity.
