Rhenus hydrogen-powered ship receive awards for sustainable inland shipping

Rhenus Group on Tuesday (21 January) said its first of three barges with hydrogen and battery-electric propulsion received the Platinum Label for environmentally friendly shipping and was also awarded the Innovation Award for Inland Navigation by the Allianz ESA 2024 in September for sustainable concepts. 

After a successful testing phase, it has been confirmed that the ship meets all construction and safety requirements and is therefore ready to start regular operations on European waterways.

The Mannheim I+II, the Rhenus Group's first inland vessel with hydrogen and battery-electric propulsion, is the first push barge combination in the world to receive the exclusive platinum label. 

This award has so far only been given to 19 European inland waterway vessels and underlines the outstanding innovative strength and commitment of the Rhenus Group to a sustainable future in shipping. In addition, the ship has been awarded the Green Award in the Gold category – proof of compliance with the highest environmental standards.

In September 2024, the Rhenus Group and its subsidiaries Rhenus PartnerShip and Contargo received an award for sustainable concepts in shipbuilding and trimodal transport. This award recognises the technology and the contribution to more environmentally friendly shipping in inland transport.

The Mannheim I+II has successfully passed the road test after undergoing extensive trials. For example, zigzag and crash-stop maneuvers were carried out to ensure the vessel's stability and safety. At the same time, several push barges were towed to determine the maximum tonnage of the push barge combination that the vessel is allowed to transport.

The test phase was carried out in close collaboration with the expert from Lloyd's Register, Office Rotterdam, to also meet the requirements for the approval of dangerous goods for container transport. The ship has now received a provisional certificate of registry and has started its first voyage with several containers towards the end of 2024.

PowerCell: Hydrogen fuel cells with methanol reformer tech offers solution to net-zero shipping

Dr. Andreas Bodén, Senior Vice President and Chief Technology Officer of fuel cell systems developer PowerCell shares with Manifold Times the potential of hydrogen fuel cells with methanol reformer technology as a solution in maritime industry’s transition towards net-zero-emission: 

 As the maritime industry transitions towards net-zero emissions, renewable fuels have been at the forefront in advancing sustainable shipping. According to Hydrogen Europe’s “Long-term outlook on zero-emission mobility” survey, e-fuels hold the most promise for various ship types, including ferries, cruise ships, and container vessels. 

Among these e-fuel options, methanol reformer technology is emerging as a potential solution in this transition. This technology can convert methanol into hydrogen onboard through steam reforming, enabling proton-exchange membrane (PEM) fuel cells with 30% greater efficiency than internal combustion engines, paving the way for compact, high-power, and net-zero energy solutions without relying on pure hydrogen infrastructure.

Hydrogen, often dubbed the building block of the energy transition, emerges as a viable option for certain vessels with fixed or shorter routes, such as passenger ferries and service vessels. However, its practicality for wider-scale use in deep-sea shipping has significant challenges related to supply of green molecules and energy density, as well as storage, transport, and handling.

Methanol addresses these challenges by serving as an easy and efficient liquid hydrogen carrier. It is easy to handle, store, and transport at ambient temperature and pressure. By serving as a hydrogen carrier, methanol overcomes the logistical obstacles of hydrogen fuel while still enabling the use of high-efficiency fuel cells. This symbiosis positions methanol and fuel cells as key players in scaling renewable fuels for the maritime industry.

Efficient use of scarce resources

Green fuels like renewable methanol face significant hurdles, from scaling production to securing offtake agreements. Marine economist Dr. Martin Stopford warns that shipping might lag behind other sectors, such as road transport and chemicals, in accessing renewable fuels. At the same time, the Methanol Institute tracks nearly 90 green methanol projects aiming to produce 9 million tons annually by 2027, some of which will benefit the marine industry.

Despite the level of optimism, renewable methanol will be a scarce and a costly resource for the foreseeable future. Lloyd’s Register estimates its initial cost at around $1,000 per ton, which is significantly higher than conventional fuels. Shipowners must therefore maximise efficiency, reducing the volume of renewable fuel required and mitigating operating expenses.

Methanol’s energy density surpasses hydrogen and ammonia but falls short of hydrocarbon fuels. Lloyd’s Register highlights that ship operators would require two and a half times more methanol than traditional fuel oil for equivalent energy output. This disparity underscores the necessity of adopting more efficient propulsion systems.

Fuel cells: A pathway to efficiency

Fuel cells with methanol reformer technology offer a solution. These systems can convert methanol into hydrogen onboard through steam reforming, producing energy from methanol 30% more efficiently than internal combustion engines. PEM fuel cells which can use this technology stand out for their compact size, efficiency, and high-power density. These technologies enable net-zero energy generation without the need for pure hydrogen infrastructure.

For smaller vessels like ferries and towboats, fuel cells can serve as the primary propulsion system, reducing renewable methanol consumption by up to 30%. Larger ships, such as container vessels, can use fuel cells to power auxiliary engines, eliminating emissions from fossil-fuel generators during port operations. Renewable methanol further curbs nitrogen oxide (NOx) emissions by up to 80%, while eliminating sulphur oxide (SOx) and particulate matter (PM) emissions. These benefits can be enhanced when using an internal combustion engine (ICE) or a fuel cell with reformer technology specifically designed to reduce local pollutants. 

Beyond methanol, fuel cell reformer technology can be developed for ammonia. This adaptability offers a pathway to the efficient use of ammonia as a future zero-carbon solution. This flexibility also allows shipowners to adopt renewable methanol now and transition to other fuels as they become viable.

Balancing sustainability and efficiency

The IMO’s revised GHG strategy targets net-zero emissions for international shipping by 2050, with interim milestones for 2030 and 2040. Achieving these goals requires efficient use of renewable fuels and innovative propulsion systems. PowerCell’s Methanol to Power Solution, M2Power 250, exemplifies the potential to enhance fuel efficiency and reduce operational costs. 

As the maritime industry is responsible for 3% of global GHG emissions, fuel cells with methanol reformers represent a practical solution. Whether powering smaller vessels or auxiliary systems on deep-sea ships, this technology bridges the gap between the current fuel limitations and the future of sustainable shipping. 

The marine industry must embrace innovative solutions to achieve net-zero emissions. Fuel cell technology, with its unparalleled efficiency and fuel optionality, positions many shipowners best to navigate the challenges of the energy transition.

ENGINE on The Week in Alt Fuels: Trump doctrine could favour blue hydrogen

Trump’s recent executive orders are unlikely to impact existing tax incentives for low- and zero-emission fuel production in the US, but they may redirect focus from green to blue fuels.

Trump’s recent executive orders are unlikely to impact existing tax incentives for low- and zero-emission fuel production in the US, but they may redirect focus from green to blue fuels.

US President Donald Trump recently issued an executive order to pause all unspent federal funding tied to the Inflation Reduction Act (IRA). Federal agencies now have 90 days to report how these funds align with the administration's broader energy goals to the Office of Management and Budget and the National Economic Council.

This order has raised questions about its potential impact on the US low- and zero-emission fuel production sector. But some experts suggest that the move is unlikely to harm the existing tax subsidies for clean fuel production under the IRA.

"All spending on Inflation Reduction Act and IIJA (Bipartisan Infra Law) ordered to be stopped by Trump Executive Order. I assume this applies to unspent discretionary grants and loans like most (all?) of DOE LPO and GDO, but not tax credits,” said Rob Gramlich, president of power-grid consultancy Grid Strategies. He added that stopping mandatory grants would venture into legal complexities under the impoundment law, which requires such funds to be spent unless overridden by the Supreme Court.

IRA tax credits like 45V for green hydrogen and 45Q for carbon capture promote the production of green and blue hydrogen-based fuels in the US by reducing the production cost of these fuels.

These subsidies could benefit several green and blue fuel projects in the US that could produce hydrogen-based fuels for the bunker market. For instance, Methanex and Woodside Energy are developing green methanol and blue ammonia production in Beaumont. HIF Global is building an e-methanol plant in Matagorda County, and LSB Industries has plans for a blue ammonia plant near the Houston Ship Channel.

Removing tax credits will raise low-carbon fuel production costs and contribute to keep price gaps with fossil fuels wide.

But since they are already enacted, removing them would require further congressional action, which could “prompt legal challenges,” according to Robert Moczulewski, senior director at tax advisory firm Baker Tilly.

Gerben Hieminga, senior energy sector economist at ING, believes that “hydrogen and CCS tax credits can survive and continue to play a crucial role in reducing costs” under the Trump administration. In fact, they may even see “loosened eligibility criteria,” which can help to reduce costs, he added.

He also noted that the freeze could impede funding for green hydrogen technologies such as electrolysers, but Trump's focus on natural gas and carbon capture and storage (CCS) might boost blue hydrogen production.

“Blue hydrogen is likely to dominate green hydrogen, allowing the industry to grow more significantly due to the larger scale of blue hydrogen projects,” he said, estimating US blue hydrogen production could reach 4.8 million mt/year by 2030, compared to only 1.2 million mt/year of green hydrogen.

While tax credits may survive Trump's presidency, Hieminga cautions that uncertainties around “tax credit guideline finalisation, non-credit funding, and government-enabled hydrogen development programmes can slow down project development.”

In other news this week, Spanish project developer Reolum plans to build a plant to produce 140,000 mt/year of e-methanol for bunkering and other industries. The plant will be located in the Castilla y León region of northwestern Spain and is expected to become operational by 2027.

Swedish e-fuel company Liquid Wind plans to build another 100,000 mt/year e-methanol production plant in Finland. The fuel produced will primarily be supplied to the maritime and aviation sectors. Commercial operations are expected to begin in 2029.

Global marine fuels supplier Monjasa will start supplying biofuel bunker blends in the Panama Canal area. Monjasa will offer ISCC-certified B30-VLSFO blends in Panama, the company said in a social media post. It expects to supply about 5,000-7,000 mt/month.

Klaipėda Port launches Lithuania’s first hydrogen-powered vessel

Klaipėda State Seaport Authority on Wednesday (22 January) said the first ever green hydrogen and electricity-powered ship in Lithuania has been moved from shipyard into water. 

Leaving no trace on the environment, it will clean other vessels entering the port, accepting waste from them.

According to the current rules, vessels are obliged to hand over the waste they produce when they arrive and before they leave Klaipėda Port. The Seaport Authority was entrusted with the collection of the waste, and the company decided to use modern and environmentally friendly equipment to further improve the quality of the ship waste collection service.

The tanker’s main function is to collect storm water, sewage, sludge and garbage, as well as to ensure efficient waste management. The ship will be equipped with special tanks and a modern rainwater treatment plant that will allow the treated water to be transferred to the city’s sewage treatment plants. The tanker will be ready to work around the clock and collect up to 400 cubic metres of liquid waste.

The tanker is 42 metres long and 10 metres wide. The ship’s power system will consist of two electric motors powered by 2,000 kWh batteries and a hydrogen fuel cell system. Depending on the intensity of the work, the tanker will be able to operate in the port of Klaipėda for up to 36 hours without additional power charging.

This ship building project with a total value of EUR 12 million (USD 12.5 million) has been commissioned by the Port Authority and is being built by West Baltic Shipyard together with Baltic Workboats under a joint operating agreement.

“We have not only launched a tanker, but also a new approach to port operations – cleaner, smarter and more environmentally friendly. This first ever hydrogen and electricity-powered ship is not only an innovative technological solution, but also an important step in strengthening Lithuania’s image as a modern maritime nation,” said Algis Latakas, Director General of Klaipėda State Seaport Authority.

“At the moment, the tanker is getting used to the seaport water, so to speak, and at the end of the year we expect it to start its important mission of taking care of the clean seaport environment. Such a decision will not leave a footprint on nature, but it will certainly leave a strong mark on our path to a greener future.”

In June last year, a symbolic keel-laying ceremony at the West Baltic Shipyard of the West Baltic Shipyard Group marked the start of the ship’s construction. To date, the hull has been fabricated and painted, with piping, valves, coolers, shaft lines, rudder feathers, heat and fire insulation installed.

Once the tanker is moved into the water, the engine room equipment will be installed, the interior of the wheelhouse will be redecorated, the electrical wiring and the main electrical engines will be installed, the hydrogen system will be installed and other work necessary for the operation of the ship will be carried out.
