To promote green shipping
MAN Diesel & Turbo and the International Windship Association (IWSA) invited 200 leaders of the maritime industry to the ‘Ambition 1.5°C: Global Shipping’s Action Plan’ to debate an agenda to reduce shipping emissions.
MAN Diesel & Turbo wants to expand the debate on how to reach COP 21’s
targets and engage with all stakeholders – whether the general public,
NGOs, shipowners or classification societies – to see what solutions are
already in place or required.
The hopes and demands of the shipping industry
for a strengthened mandate of the IMO were not fulfilled in Paris; Bonn offers
us a new opportunity to accelerate what MAN Diesel & Turbo calls the
‘Maritime Energy Transition’, the move to cleaner technology within our
industry. Ultimately, uniform environmental standards must be established at
international level – a strong IMO as an international regulator is therefore
The term ‘Maritime Energy Transition’ stems from the German expression ‘Energiewende’ and encapsulates MAN Diesel & Turbo’s call to action to reduce emissions and establish natural gas as the fuel of choice in global shipping. It promotes a global ‘turn to gas’, driven by the IMO, and a common approach by the shipping industry and politics to invest in infrastructure development and retrofits.
Launched in 2016 after COP 21, the initiative has since found broad support within the shipping industry and German politics.
The Maritime Energy Transition is also an umbrella covering all MAN Diesel & Turbo activities in regard to supporting a climate-neutral shipping industry, including:
In the German city of Herten, in the Ruhr region, a waste-to-energy plant is about to supplement its electricity and heat production with a steam turbine by MAN Diesel & Turbo. The operator of the plant, Abfallentsorgungsgesellschaft Ruhrgebiet [Ruhr Waste Disposal Company], has ordered the highly flexible MAN turbine of the MARC series to raise its output of both district heating and electric power. The climate-friendly expansion of regional supplies will provide additional heating energy for around 25,000 households in the district heating network of the Ruhr region, which is also currently being expanded.
In total, six combustion lines in Herten generate high-energy steam, converted by steam turbines and generators to electrical power and district heating. In the cooler months of the year, the focus is on decoupling district heating as heat energy; in the summer the emphasis is on power generation. The additional MAN Diesel & Turbo steam turbine generator set will support this varying operation with a maximum degree of flexibility and efficiency.
"Projects such as this demonstrate the transition that is going on in the energy landscape," explains Holger Kube, Head of Sales Power Generation at system manufacturer MAN Diesel & Turbo in Oberhausen. "Smaller steam turbines such as our MARC series are used primarily by regional suppliers and industrial companys. Away from large-scale power plants, they generate electrical power and heat both for local demand and for feeding into the grid. For this decentralized form of power generation, various fuels are used. In addition to waste, this is also biomass or the waste heat from industrial processes."
He adds: "In the medium term, we foresee a trend toward such plants in the small to medium output range, and not just in Germany. Besides the pure efficiency, flexibility is a deciding factor, allowing the operator to respond to fluctuating supply and demand requirements. While the requirements for the plant in Herten vary seasonally, the requirements of the energy market as a whole are increasing, in part due to the fluctuating supply from renewable sources. Here, efficient, flexible and reliable solutions are needed," Kube explains.
