Scatec ASA, a renewable energy solutions provider, has signed the power purchase agreements for the three Kenhardt projects in the Northern Cape Province of South Africa, under the Risk Mitigation Independent Power Producer Procurement Programme (RMIPPPP)
In the latest issue of African Review, Fabrice Mpollo, investment manager at Norfund, discussed the prospects of off-grid and renewable energy projects on the continent
The series of projects announced in Egypt over the past three months has captivated foreign developers, highlighted the country’s potential, and came as the country gears up to host COP27 in 2023
Egypt’s pipeline for green hydrogen projects stands at 11.62GW, equivalent to over 1.57mn tonnes of green hydrogen, ranking the country in the top three green hydrogen pipelines globally, after Australia and on par with Mauritania
The estimated cost for these hydrogen projects alone, without additional infrastructures, will be around US$20bn. The projects are expected to come online before 2035, according to Rystad Energy research.
The interest shown by international developers in Egypt is due to some favorable factors including the country’s location, natural gas infrastructure, liquefaction facilities, bunkering market, and marine ports, as well as its high solar and wind potential. Egypt is also close to markets like the European Union and the Middle East – regions set to see a huge demand for hydrogen in the coming years.
The government of Egypt plans to release a US$40bn national hydrogen plan in the coming months, recognising the importance of production, storage and export/import of green hydrogen and ammonia under its economic development strategy and allowing for state support and tax incentives. The process of establishing, operating, and managing hydrogen projects has been simplified, requiring a single permit, which means less red tape.
“Egypt has all the prerequisites to become a green hydrogen giant – fantastic renewable potential, space for mega projects and construction expertise. The US$40bn in planned investments by the Egyptian government demonstrates commitment and will bring further foreign investment. Sitting between three continents and with the Suez Canal carrying approximately 12% of all the seaborne freight in the world, Egypt can supply renewable energy near and far,” commented Minh Khoi Le, head of hydrogen at Rystad Energy.
This plan would be a huge development for Egypt’s green hydrogen economy. The upcoming legislation will enable green hydrogen and ammonia plans, and with the over 11GW of projects already announced, Rystad Energy expects a huge inflow of foreign investment into the country. Several feasibility studies and MoUs between Egyptian state entities and leading international ammonia and hydrogen market players for the development of green ammonia and green hydrogen have been reported in 2021.
Project by capacity
Major announcements made this year include French utility EDF and ZeroWaste, a UAE-based project developer, which signed an MoU with Egypt's Suez Canal Economic Zone (SCZONE) to produce 350,000 tonnes of green fuel annually in the Ain Sokhna region for ships, vessels, and tankers crossing the Suez Canal. The project’s first phase will produce 140,000 tonnes of green ammonia using close to 25,000 tonnes of green hydrogen from desalinated seawater and renewable energy as feedstock. Commissioning is scheduled for 1Q 2026.
Rolls-Royce has taken a significant step towards meeting its net zero goals, set out last year, with the approval of its mtu Series 4000 and Series 1600 diesel engines for use with sustainable fuels in power generation applications
Following successful trials on the test bench and in the field, Rolls-Royce business unit power systems has approved its Series 1600 and Series 4000 generator sets for use with EN15940 synthetic diesel fuels.
"There is already a lot of interest in HVO in particular from many customers in the energy industry and data center business who want to improve their carbon footprint," explained Tobias Ostermaier, president, stationary power solutions at Rolls-Royce Power Systems. "The results from pilot customers show a significant reduction in greenhouse gases, nitrogen oxide and particulate emissions by using HVO instead of fossil diesel in their gensets."
HVO use significantly reduces CO2, nitrogen oxide and particulate emissions
Waste vegetable and animal fats and used cooking oils can be used as base materials for HVO, which are converted into hydrocarbons by means of a catalytic reaction with the addition of hydrogen. The advantages of HVO are clean combustion with a reduction in particulate emissions of up to 80%, nitrogen oxide emissions by an average of 8% and (depending on the manufacturing process and feedstock) CO2 emissions by up to 90% compared to fossil diesel. Because HVO fuel is produced from renewable raw materials, its production, transport, and combustion generate only about as many greenhouse gases as were absorbed by the plants during the growth of the biomass.
Convincing performance without engine and system modifications
The tests confirmed that mtu engines perform equally excellent when using HVO (as compared to diesel) in terms of maximum power, load acceptance and fuel consumption. HVO is a drop-in fuel, which means that there are no adaptions needed to the diesel plant infrastructure, hardware or software for its use.
Target: 35% greenhouse gas savings by 2030 with new fuels and mtu technologies
As part of its sustainability programme, Rolls-Royce announced in the middle 2021 that it would realign its product portfolio so that by 2030, new fuels and mtu technologies can save 35% greenhouse gas emissions compared to 2019 levels. The company is now already successfully operating an mtu fuel cell system, has established a clear roadmap for the introduction of hydrogen engines, and is now progressively releasing further engines in more applications to run on sustainable fuels.
New capacity for generating electricity from solar, wind and other renewables has increased to a record level worldwide in 2021 and will grow further this year as governments increasingly seek to take advantage of renewables’ energy security and climate benefits, according to the International Energy Agency
