El consorcio liderado por el suministrador de naves de emisiones cero, ACUA Ocean, en colaboración con el proveedor de infraestructura de emisiones cero, Unitrove, ha obtenido una subvención multimillonaria del gobierno británico en un importante impulso para descarbonizar el sector marítimo, según informó Unitrove.

El consorcio, el cual ha sido bautizado como “Hydrogen Innovation – Future Infrastructure & Vessel Evaluation and Demonstration (HI-FIVED)” recibirá más de US$4.553 millones de financiación para construir y exhibir sus innovadoras tecnologías de buques autónomos e infraestructuras de repostaje de hidrógeno líquido.iales

Se prevé que el proyecto, dotado con US$6.442 millones, estará terminado en otoño de 2024 y su objetivo es establecer un corredor marítimo ecológico entre Aberdeen y las Islas Orkney y Shetland para el transporte de

China has maintained its leadership in the global race for new offshore wind turbine installations despite an expected decline in annually added capacity, according to the latest numbers from the World Forum Offshore Wind (WFO).

The WFO's annual report shows that nearly seven gigawatts of offshore wind capacity was added in China in 2022, a substantial drop compared to 12.7 GW of new capacity that was added to the national grid in 2021.

The plunge was attributed to the expiration of a favorable Chinese feed-in tariff, which

Abstract

The trend to replace internal combustion engines with electric zero-emission drives, visible in the automotive industry, also exists in the shipbuilding industry. In contrary to land vehicles, the requirements for the electric propulsion system of tugs are much greater, which combined with the limited space and energy on

South Africa is one of the largest countries in Africa, the 25th biggest in the world, and currently ranked 31st among major economies and 99th in the list of the richest countries in the world..

South Africa came out of a very long and hard struggle against apartheid (an institutionalized system of racial segregation) finally becoming a democracy in 1994..

Fast forward to 2023, South Africa is facing another major struggle, this time, economic in nature, caused by “load-shedding” which has continued for the past 14 years with no real solution in sight..

Load shedding is the intentional and controlled reduction of electric power supplied to certain areas in order to prevent a total blackout or power failure..

It is a common practice
