Ulstein introducing hydrogen fuel cell off-shore vessel; sea trials could happen in 2022
Recently, DNV GL identified the five most promising alternative fuels for shipping, with hydrogen as the ultimate zero-emission solution. The first complete hydrogen-fueled prospect has now been assembled by Ulstein Design & Solutions BV and Nedstack Fuel Cell Technology BV. The ULSTEIN SX190 Zero Emission DP2 construction support vessel is Ulstein’s first hydrogen-powered offshore vessel, featuring a Nedstack fuel cell power system. The DP2 vessel can cater for a large variety of offshore support operations. Sea trials of a newbuild ULSTEIN SX190 Zero Emission could happen as soon as 2022. This design uses proven and available technology, enabling clean shipping operations to reduce the environmental footprint of offshore projects. CO2, NOx and PM emissions are eliminated when using hydrogen fuel cells. The maritime industry needs to align and be ambitious in bringing green solutions forward for a sustainable future. With this hydrogen-fueled vessel, we aim for future zero-emission operations of long endurance.—Tore Ulstein, deputy CEO, Ulstein Group With today’s technology, the ULSTEIN SX190 design is already capable to operate 4 days in zero-emission mode. However, with the rapid developments in hydrogen storage and fuel cell technologies, a future zero-emission endurance of up to two weeks is targeted. For extended missions and capabilities, the vessel can fall back on its more conventional diesel-electric system using low sulfur marine diesel oil. The ULSTEIN SX190 Zero Emission design is based on Ulstein’s existing SX190 vessel platform and has a total installed power of 7.5 MW, of which 2 MW is generated by a fuel cell power system, typically Nedstack Proton Exchange Membrane (PEM) fuel cells, which are located in a separate, second engine room. Nedstack fuel cell systems have already been built and proven in the multi-megawatt power ranges and have now been marinized to meet the requirements of the marine industry, including class requirements and supply chains. Ulstein is constantly looking to improve marine operations and to reduce the environmental footprint of the vessels we deliver to the market. Implementing fuel cell technology in a workhorse like the SX190 CSV design is one of the steps we take to move the marine industry into a more sustainable future, in addition to our X-BOW hull shape, ULSTEIN ZED ‘get-in-and-leave-no-trace solution’ and plug-in hybrid solutions.—Ko Stroo, product manager at Ulstein Design & Solutions BV The PEM fuel cells used in the SX190 Zero Emission design are fueled by hydrogen from containerized pressure vessels, a well-proven and readily available technology. These hydrogen storage containers can be loaded and unloaded by normal container handling operations and equipment, thus eliminating the need for expensive bunkering infrastructure and providing worldwide operational flexibility. The hydrogen containers can be refilled at hydrogen production sites, either from industry by-product hydrogen or green hydrogen from electrolysis, making the vessel globally employable.

Cummins announces PLANET 2050 strategy; net-zero carbon emissions by 2050
Cummins Inc. announced its next environmental sustainability strategy—PLANET 2050—which includes science-based goals that meet or exceed the goals in the United Nations Paris agreement on climate change. By 2050, Cummins is targeting net-zero carbon emissions. PLANET 2050 focuses on three priority areas: addressing climate change and air emissions; using natural resources in the most sustainable way; and improving communities. It includes eight specific goals, timed to 2030, as well as aspirational targets for 2050. It is the most comprehensive and ambitious environmental sustainability strategy ever pursued by the company. Specific 2030 goals related to parts, products, and company-managed facilities and operations are: Reduce absolute greenhouse gas emissions from facilities and operations by 50% (science-based target). Reduce absolute lifetime greenhouse gas emissions from newly sold products by 25% (science-based target). Partner with customers to reduce greenhouse gas emissions from products in the field by 55 million metric tons. Reduce volatile organic compounds emissions from paint and coating operations by 50%. Create a circular lifecycle plan for every part to use less, use better, use again. Generate 25% less waste in facilities and operations as a percent of revenue. Reuse or responsibly recycle 100% of packaging plastics and eliminate single-use plastics in dining facilities, employee amenities and events. Reduce absolute water consumption in facilities and operations by 30%. Cummins will invest to achieve the goals, which will require new technology and capabilities. The company has a history of developing challenging goals and then finding ways to achieve them. Cummins reports results transparently even when falling short of goals. As Cummins has done with past environmental goals, the progress on 2030 goals will be periodically evaluated and communicated including consideration of whether more can or should be done in line with global energy and environmental challenges. In 2020, Cummins will launch a strategic community environmental program to align its efforts and affirm its commitment to the environment as one of the company’s three community priority areas. Also, as part of its focus on communities and natural resources, Cummins joined the CEO Water Mandate, which is focused on addressing global water challenges through corporate water stewardship, in partnership with the United Nations, governments, civil society organizations, and other stakeholders. Cummins will continue to work in partnership with others to advocate for tough, clear and enforceable regulations across the globe to address air emissions and for science-based climate policies. Earlier this year, Cummins’ executives testified before two US Congressional committees, advocating that legislation should include national-level emissions targets for product-specific applications, regulatory certainty and realistic implementation schedules. They also supported robust federal investment in research and development, grant programs for adoption of new technologies, and tax incentives. We recognize that achieving our strategy requires Cummins to invest in new technologies along with the development, implementation and enforcement by governments of clear regulations that drive down economy-wide air and greenhouse gas emissions. We will continue to work with trade associations, our customers, suppliers, community leaders, and other stakeholders to advocate for policies in line with our 2050 targets.—Brian Mormino, Executive Director Worldwide Environmental Strategy and Compliance A team of experts created Cummins’ plan after consulting the United Nations Sustainable Development Goals, analyzing best practices globally, considering the unique needs of the company’s stakeholders, and undertaking significant internal review. In 2017, Cummins formally committed to developing science-based targets under the Science Based Target Initiative, which provides a framework for the calculation of greenhouse gas goals for products and facilities that are in line with recommendations by climate scientists. In 2019, Cummins was named to the S&P Dow Jones Sustainability Index for North America for a 14th consecutive year. In 2006, the company set its first facility energy and greenhouse gas goal and joined US EPA Climate Leaders program, firmly stating its commitment to addressing climate change. In 2014, the company released a global environmental sustainability plan with facility goals in water, waste, and energy. Progress against the goals is publicly reported annually in Cummins’ Sustainability Progress Report. From our perspective, it is hard to overstate the significance of the leadership Cummins is demonstrating with PLANET 2050. Two things in particular stand out: 1) a commitment to carbon neutral products and operations as one of the world’s leading power companies and, no less importantly, 2) a call to action and commitment to positive public advocacy supporting the policies that will be essential to enabling a prosperous low-carbon economy.—Eric Olson, Senior Vice President at BSR BSR (Business for Social Responsibility) is a global nonprofit organization that works with its network of more than 250 member companies and other partners to build a just and sustainable world. From its offices in Asia, Europe, and North America, BSR develops sustainable business strategies and solutions through consulting, research, and cross-sector collaboration.

Bunched Pt-Ni alloy nanocages as efficient catalysts for fuel cells
An international team of researchers has synthesized one-dimensional bunched platinum-nickel (Pt-Ni) alloy nanocages with a Pt-skin structure for the oxygen reduction reaction in fuel cells. The nanocages display high mass activity (3.52 amperes per milligram platinum) and specific activity (5.16 milliamperes per square centimeter platinum)—nearly 17 and 14 times higher respectively as compared with a commercial platinum on carbon (Pt/C) catalyst. A paper on their work is published in Science. The catalyst exhibits high stability with negligible activity decay after 50,000 cycles. Experimental results and theoretical calculations reveal the existence of fewer strongly bonded platinum-oxygen (Pt-O) sites induced by the strain and ligand effects. The fuel cell supported by this catalyst delivers a current density of 1.5 amperes per square centimeter at 0.6 volts and can operate steadily for at least 180 hours. Platinum (Pt) is the most active electrocatalyst for the oxygen reduction reaction (ORR) in fuel cells and metal-air batteries with promising stability. Nevertheless, the state-of-the-art Pt catalysts still lack activity and stability with respect to the cost and availability for large-scale commercial implementation. Engineering the near-surface composition of nanostructured Pt alloys represents one promising approach to enhance the electrocatalytic performance of Pt-based electrocatalysts, in which the exposure of highly active sites with optimum performance can be maximized. Adding other transition metals can enhance the catalytic performance via ligand and strain effects through modifying the binding strength of Pt-oxygen intermediates. The introduction of open nanostructures, including hollow and porous nanoparticles such as nanocages (NCs) and nanoframes, may help in achieving this goal and also enhance mass transfer.—Tian et al. To prepare the nanocages, the team first prepared 1D Pt-Ni bunched nanospheres (BNSs) by reducing Pt and Ni precursors with varying ratios by a one-pot solvothermal method. Treatment under acidic conditions selectively removed Ni species to leave 1D Pt-Ni BNCs with ultrathin walls composed of a platinum skin and a residual platinum-nickel alloy below this skin. Schematic illustration of the preparation of Pt-Ni BNCs. Tian et al. This work provides an effective strategy for the rational design of Pt alloy nanostructures and will help guide the future development of catalysts for their practical applications in energy conversion technologies and beyond.—Tian et al.

Volkswagen Group to invest ~€60B in hybridization, electric mobility and digitalization over next 5 years; ~€33B on electromobility
Planned investments and development costs for future areas such as hybridization, electric mobility and digitalization will total roughly EUR 60 billion between 2020 and 2024 Share of planned spend for future topics increased in Planning Round 68 to approximately 40 percent from approximately 30 percent in the previous Planning Round Under the Volkswagen Group’s Planning Round 68, the investment plan for 2020 to 2024, the Group plans to spend nearly €60 billion (US$66 billion) on the future areas of hybridization, electric mobility and digitalization over the next five years. This amounts to slightly more than 40% of the company’s investments in property, plant and equipment and all research and development costs during the planning period. Compared with the Group’s last Planning Round, it represents an increase of around 10 percentage points. The Group intends to invest around €33 billion (US$36 billion) of this figure in electric mobility alone. We will step up the pace again in the coming years with our investments. Hybridization, electrification and digitalization of our fleet are becoming an increasingly important area of focus. We intend to take advantage of economies of scale and achieve maximum synergies. In light of the worsening economic situation, we are also working on increasing our productivity, our efficiency and our cost base so as to secure meeting our targets.—Herbert Diess, CEO of the Volkswagen Group During Planning Round 68, the long-term plan for the next 10 years was also modified. Through 2029, the Group plans to introduce up to 75 all-electric models to the market along with about 60 hybrid vehicles. The number of projected e-vehicles will rise to about 26 million, largely due to the addition of a year to the planning period to include 2029. Volkswagen is also planning to sell nearly 6 million hybrid vehicles by 2029. About 20 million of the e-vehicles planned through 2029 will be based on the Group’s Modular Electric Drive Matrix (MEB). Most of the remaining 6 million vehicles will be based on the High Performance Platform (PPE). E-vehicles are scheduled to be made outside Germany by the company’s plants in Mlada Boleslav, Chattanooga, Foshan and Anting. Others will be produced by German plants in Zwickau, Emden, Hannover, Zuffenhausen and Dresden. Plans for the Emden site were confirmed, according to which production of the electric A-SUV (ID.Next) should start in 2022. A camouflaged version of the ID.Next was already presented at this year’s Internationale Automobil-Ausstellung (IAA). A decision about a planned multi-brand plant is scheduled to be made by the end of the year. The Chinese joint ventures are not included in the consolidated group and are therefore excluded from the above-mentioned planning. These joint ventures finance investments in plants and products from their own resources.
