Alfen to create sustainable energy installation for Theobroma
The system will combine solar power, bio energy from cocoa shells, and large-scale battery storage to sustainably produce energy and steam, guaranteeing a reliable energy supply. It will also cut operational costs and carbon emissions, saving over a million litres of diesel per year.
The energy grid in Nigeria is not always reliable, and as such, Theobroma – which processes cocoa beans to make high-end cacao products for the chocolate industry – uses diesel generators for its power. This, of course, causes pollution, is expensive, and is not always available locally.
Alfen was awarded the contract to build a sustainable end-to-end energy installation for Theobroma, composed in part of over 8,000 solar panels that will be installed on roofs and the factory terrain of its facility. This will be combined with Alfen’s in-house developed battery storage system to optimise the generated electricity, and the bio energy created with cocoa bean waste.
Evert Raaijen, Sales Engineer Energy Storage at Alfen, said: “With two energy storage systems of approximately 1 MWh each, this is the largest local energy storage project in Nigeria. With the combination of solar energy and battery storage, we expect to help Theobroma attain an annual saving of over one million liters of diesel”.
Alfen is carrying out the entire project, from design to maintenance, and the project should be completed in 2018.
Raaigen continued: “The installation we’re building for Theobroma is a combination of system innovations, integrated with existing solutions. We are highly specialized in complex system integrations with energy storage solutions such as these systems. Theobroma will be able to remotely monitor performance with our back office system, while maximum savings are attained with smart power management features. Furthermore, this installation is a modular system, which enables quick and easy future upscaling.”
Trafigura and Yara International explore clean ammonia usage
Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050.
How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.
Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:
- The supply of clean ammonia by Yara to Trafigura Group companies
- Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
- Development of new clean ammonia assets including marine fuel infrastructure and market opportunities
Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.
There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.
Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.
Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.
Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.
It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
