MAN Energy Solutions, DNV to collaborate on decarbonization, hydrogen value-chain and digitalization in maritime industry
https://www.greencarcongress.com/2022/0 ... manes.html

MAN Energy Solutions and classification society DNV have signed a Memorandum of Understanding (MoU). Effective immediately, the MoU is due to run for a period of three years. Under its terms, the two companies will—by 30 June 2022—detail action plans within the fields of decarbonization, the hydrogen value-chain and digitalization. . . .

A survey taken on future fuels in the maritime industry by MAN Energy Solutions found that in this short- and medium-term, LNG / SNG / biogas are taking the lead, closely followed by MGO / ULSFO / VLSFO. Future fuels are also on the rise, with ammonia, hydrogen, methanol and biofuels taking the lead. On the other hand, conventional fuel types such as HFO with scrubber are still considered a viable way for upcoming projects.

The two-stroke side sees two major areas: LNG / SNG / biogas followed closely by ammonia, hydrogen and methanol. On the four-stroke side a different focus can be found with hydrogen taking the clear lead, followed next by LNG / SNG / biogas, ammonia and methanol.


ATI FlyZero project finds green liquid hydrogen most viable zero-carbon emission fuel for aircraft
https://www.greencarcongress.com/2022/0 ... yzero.html

FlyZero is the UK’s Aerospace Technology Institute (ATI) project aiming to realize zero-carbon emission commercial aviation by 2030. Funded by the Department for Business, Energy and Industrial Strategy, the project FlyZero began in early 2021 as an intensive research project investigating zero-carbon emission commercial flight.

The independent study brought together experts from across the UK to assess the design challenges, manufacturing demands, operational requirements and market opportunity of potential zero-carbon emission aircraft concepts.

FlyZero compared zero-carbon emission energy sources such as batteries, hydrogen and ammonia; the team concluded that green liquid hydrogen is the most viable, able to power large aircraft utilizing fuel cell, gas turbine and hybrid systems. For aviation to achieve net zero 2050 FlyZero determined that there must be investment now in both the development of sustainable aviation fuel (SAF) and green liquid hydrogen technologies.

Other major conclusions are:

Technology acceleration is key as industry and aviation can only afford one fleet refresh between now and 2050. This gives a window of opportunity to introduce zero-carbon emission aircraft in the regional, narrow-body and mid-size market segments. FlyZero modeled these concepts and determined that it is feasible to design and fly an experimental aircraft across the Atlantic by 2030 powered by hydrogen gas turbines.

The regional concept, powered by fuel cells, carries 75 passengers up to 800 nmi at a speed of 325 knots. Fuel cells are likely to be more competitive at smaller aircraft sizes than the FlyZero regional concept where the overall power requirement is lower. Its main advantages are that it only emits water and eliminates all other exhaust emissions (CO2, NOx, particulates).

The narrow-body concept carries 179 passengers up to a design range of 2400 nmi at a speed of 450 knots. The concept has the energy storage and propulsion system located at the rear of the aircraft, this includes the fuel tanks, fuel system and gas turbines.

The mid-size concept carries 279 passengers with a design range of 5750 nmi at a speed of 473 knots and an operational range of 5250 nmi. This means destinations including San Francisco (4664 nmi) and Beijing (4414 nmi) are within reach from London direct while Auckland (9991 nmi), Sydney (9198 nmi) and Honolulu (6289 nmi) are in reach with just one stop. FlyZero analysis concluded that a mid-size hydrogen aircraft could efficiently address 93% of existing long-haul scheduled flights and, therefore, the majority of emissions in this market sector.

The optimum route to decarbonizing aviation is through acceleration of a large (narrow-body and mid-size) commercial aircraft into service. FlyZero’s mid-size aircraft is able to reach all destinations in the world with a single stop. Less commercially risky than developing a narrow-body first, it would allow infrastructure development to be focused on fewer, but larger international hub airports.

Global cumulative CO2 emissions from aviation could be reduced by 4 gigatons (Gt) by 2050 and 14 Gt by 2060. This requires 50% of the commercial fleet to be hydrogen-powered by 2050 and assumes mid-size hydrogen-powered aircraft are operating by 2035, with hydrogen-powered narrow-body aircraft in service by 2037. It is critical to achieve these dates to hit the net zero 2050 goal.

Revolutionary technology breakthroughs are required in six areas to achieve zero-emission flight: hydrogen fuel systems and storage; hydrogen gas turbines; hydrogen fuel cells; electrical propulsion systems; aerodynamic structures; and thermal management. The UK has expertise and capability today in these, but little in liquid hydrogen fuels. Climate science is also fundamental to aerospace research.

From the mid-2030s, liquid hydrogen is forecast to become cheaper as well as greener than Power to Liquid SAF which is expected to be the primary SAF as demand increases. PtL SAF requires more electrical energy to produce than liquid hydrogen. Scalability of other SAFs is limited by availability of raw materials.

Hydrogen-powered aviation will require new aircraft certification policies. New health and safety regulations will also be needed for transporting and storing liquid hydrogen at airports and refuelling aircraft. Regulators will need to take a global approach to developing and adopting these. . . .


Maersk, Egyptian authorities sign partnership agreement to explore large-scale green fuel production in Egypt
https://www.greencarcongress.com/2022/0 ... aersk.html

In the presence of the Egyptian Prime Minister, a Memorandum of Understanding (MoU) was signed on Monday in a joint bid to further accelerate the supply of green fuels and the global transformation to net-zero shipping. This partnership follows six fuel sourcing partnerships announced earlier this month, and with it Maersk joins forces with the General Authority for Suez Canal Economic Zone (SCZone), the Egyptian New and Renewable Energy Authority (NREA), the Egyptian Electricity Transmission Company (EETC), and the Sovereign Fund of Egypt for Investment and Development (TSFE).

Egypt has excellent conditions for renewable energy production and ambitions to become global leader in the green energy value chain. We are very excited to be able to explore options together, drawing on our more than 100 years of business relations in the country.

The availability of green energy and fuel in sufficient quantities and at cost competitive price levels is the single biggest challenge to the decarbonisation of global shipping. For Maersk, our recently announced strategic partnerships with six industry leading companies are key in addressing this challenge, but to stay on the 1.5-degree pathway even more scale is needed within this decade. That is what this partnership is exploring.


—Henriette Hallberg Thygesen, CEO, Fleet & Strategic Brands, Maersk

The parties will be conducting a feasibility study before the end of 2022 to examine an Egypt-based hydrogen and green marine fuel production, powered by renewable energy with Maersk as committed offtaker. . . .

Maersk intends to explore similar opportunities in other regions with strong potential for renewable energy development, drawing on business and governmental relations to facilitate opportunities for nations and commercial players to embrace the rapid acceleration in green fuel production that is key to the decarbonization of shipping.


US-based Raven SR to build waste-to-hydrogen project in Spain
https://www.greencarcongress.com/2022/0 ... raven.html

Raven SR, a US-based renewable fuels company (earlier post), plans to build a waste-to-hydrogen production facility in Aragón, Spain, following the opening of its subsidiary Raven SR Iberia in Zaragoza, announced earlier this month. The Raven SR project in Aragón will produce 1,600 metric tons per year of renewable hydrogen from approximately 75 tons of organic solid waste per day. Raven SR plans to bring the modular project online in 2023. . . .

Raven’s technology can convert any carbonaceous feedstock into a synthetic gas that is 55-65% hydrogen—higher than most processes, including plasma arc gasification. This hydrogen-rich syngas produces higher quantities of fuels with fewer emissions than any competing technology.

Raven can also add small amounts of CO2 to adjust the H2/CO ratio in the process that is needed for FT fuel production. About 15% of feedstock is converted into a solid bio-carbon which can potentially be sold. . . .


Hydrogen refueling station operator H2 MOBILITY Deutschland raises €110M
https://www.greencarcongress.com/2022/0 ... 1-h2m.html

Hydrogen refueling station operator H2 MOBILITY Deutschland closed a €110-million investment round. Hy24, the world’s largest clean hydrogen infrastructure investment platform, led the round with €70 million. Air Liquide, Daimler Truck, Hyundai, Linde, OMV, Shell, and TotalEnergies also contributed to the capital raise.

H2 MOBILITY, a leading operator of hydrogen refueling stations which already operates more than 90 stations across Germany, intends to use the funding to further expand its network to 300 stations by 2030, becoming the backbone of zero-carbon private and commercial traffic in Europe.

Of these, more than 200 will be large-scale refueling stations capable of meeting demand for zero-carbon, heavy-duty and long-haul transportation on the European Continent.

The expansion of H2 MOBILITY Deutschland’s network will be focused on several high-traffic transportation corridors, giving it a cornerstone role in the future mobility system of the European Union. . . .


ZeroAvia and ZEV Station sign MoU to develop hydrogen refueling ecosystem at California airports
https://www.greencarcongress.com/2022/0 ... oavia.html

ZeroAvia, a developer of hydrogen-electric aviation, signed an MoU and announced a new partnership with the hydrogen fueling firm ZEV Station to develop green hydrogen refueling infrastructure for airports in California.

The companies will work together on developing an initial regional airport project that represents sufficient scale to showcase how hydrogen-electric propulsion systems can deliver zero-emission commercial flights. ZeroAvia will leverage its significant research and development in hydrogen production and refueling for aviation alongside ZEV Station’s extensive team experience in the provision of gaseous hydrogen for road vehicles, in order to develop an innovative hydrogen airport refueling system.

As part of the partnership, ZeroAvia plans flight demonstrations of hydrogen-electric aircraft from pilot airports, supported by the co-developed refueling ecosystem and dedicated support from ZEV Station.

ZeroAvia has already developed a fully functioning microcosm of potential refueling operations. The Hydrogen Airport Refueling Infrastructure (HARE), developed as part of the HyFlyer projects in conjunction with the European Marine Energy Center (EMEC), has demonstrated green hydrogen production through to airside fueling.

Airports are central points of significant demand thanks to the high volumes of hydrogen required to power aircraft. Busy hubs can produce economies of scale for hydrogen production and thus make it more economical to remove greenhouse gas emissions in other areas such as ground operations, onward transportation links, and proximate industry. . . .

ZEV Station, with a main office in Palm Springs, California is engineering a highway zero-carbon fueling station for both Fuel Cell and Electric vehicles at the same forecourt. Their charging-only test site is slated to open at the end of next month. The first Premier ZEV Station with both charging and hydrogen is under permitting and targeted for operation in early 2023. ZEV Station is in the planning for a network of stations with production of their own hydrogen, delivering to satellite stations. . . .

In the coming weeks, ZeroAvia will begin flight-testing its hydrogen-electric powertrain using its Dornier-228 testbed aircraft. This work, part of the HyFlyer II project, will deliver a fully certified 600kW model for aircraft of up to 19-seats for 2024 and is supported by the UK Government’s Department for Business, Energy and Industry Strategy (BEIS), Aerospace Technology Institute (ATI) and Innovate UK through the ATI Program.

The company plans to scale up its technology to 40-80 seat aircraft by 2026, with ground tests of the 1.8 megawatt power plant prototypes starting this year.

Oil sands company Suncor Energy strengthens its focus on hydrogen and renewable fuels, divesting wind and solar
https://www.greencarcongress.com/2022/0 ... uncor.html

Suncor Energy, a Canadian integrated energy company that is one of the top oil sands producers in the country, will strengthen its focus on hydrogen and renewable fuels to accelerate progress towards its objective to be a net-zero company by 2050. Suncor also plans to divest its wind and solar assets. . . .

In 2002, Suncor partnered with Enbridge to build one of the first renewable energy projects in Canada and since then, Suncor has developed eight wind power projects in three provinces—Saskatchewan, Alberta and Ontario. Moving forward, Suncor will continue to participate in many aspects of the electricity value chain, including producing power through its integrated co-generation operations, through power marketing and trading, by providing customers with EV charging and potentially procuring renewable power through power purchase agreements.

Suncor’s strategy is focused on increasing shareholder returns and accelerating its progress to be a net-zero company by 2050. In support of this objective, Suncor is focusing its efforts in areas that are complementary to its base oil sands business including replacing coke-fired boilers at Base Plant with lower emission cogeneration units and accelerating commercial scale deployment of carbon capture technology.

Other targeted activities include partnering with ATCO on a project to build a world-scale hydrogen project in Alberta and deploying next generation renewable fuel technologies such as Lanzajet’s sustainable aviation fuel technology and Enerkem’s waste-to-fuels technology. . . .

Suncor is one of the founders of the Oil Sands Pathways to Net Zero initiative—an alliance of oil sands producers working collectively with the federal and Alberta governments to achieve net zero greenhouse gas (GHG) emissions from oil sands operations by 2050 to help Canada meet its climate goals.


Next Hydrogen, Black & Veatch sign MoU to develop large-scale integrated green hydrogen solutions
https://www.greencarcongress.com/2022/0 ... 11-nh.html

Next Hydrogen Solutions Inc., a designer and manufacturer of electrolyzers, recently signed a memorandum of understanding (MoU) with Black & Veatch, a global engineering, procurement, consulting and construction company, to offer a complete and integrated solution for producing large-scale green hydrogen for industrial customers.

Next Hydrogen will combine its technology and electrolysis expertise with Black & Veatch’s market leadership in large-scale industrial engineering solutions to target broad applications worldwide for industrial and transportation customers. . . .


thyssenkrupp nucera to deliver electrolyzers for Air Products’ hydrogen facility in Arizona; 2nd joint project under strategic partnership
https://www.greencarcongress.com/2022/0 ... krupp.html

Air Products has awarded thyssenkrupp nucera a contract for the supply of alkaline water electrolysis technology for a 10 metric ton per day facility to produce green liquid hydrogen in Casa Grande, Arizona. Under this contract, thyssenkrupp nucera will deliver two of their large-scale alkaline water electrolysis standard modules. . . .

. . . thyssenkrupp nucera has developed a modularized and cost-efficient solution for large scale hydrogen production. (Earlier post.) To simplify the construction of new hydrogen plants and keep costs down, it offers electrolyzers in prefabricated skid-mounted modules that can be added up to several hundred megawatts up to gigawatt scale.

Project activities have been initiated, and the facility is expected to be on-stream in 2023. The gaseous hydrogen will be converted to liquid hydrogen using Air Products’ proprietary technology. The production site will also include a terminal for Air Products to distribute the product for the mobility market in California and other locations in the US. . . .

Through several regulations California has taken steps aggressively to decarbonize its transportation sector—the largest emissions sector in its economy—through conversion to zero-emission vehicles. The state has also set a goal that all drayage trucks be zero-emissions by 2035 and heavy-duty vehicles convert to zero-emissions vehicles by 2045.

For heavy-duty applications, hydrogen fuel cells offer faster refuel times, longer range, and larger payloads, while also performing better in extreme climate conditions than battery-electric solutions. Hydrogen as a transportation fuel most closely mirrors the traditional transportation fueling experience. . . .


Shell and Uniper to work together on blue hydrogen production facility in the UK
https://www.greencarcongress.com/2022/0 ... umber.html

Uniper has signed an agreement with Shell to progress plans to produce blue hydrogen at Uniper’s Killingholme power station site, in the East of England. The hydrogen produced could be used to decarbonize industry, transport and power throughout the Humber region.

Blue hydrogen refers to hydrogen produced by the reformation of natural gas, with the CO2 produced as a result of this process being captured and stored using CCS technology.

The Humber Hub Blue Project includes plans for a blue hydrogen production facility with a capacity of up to 720 megawatts (MW), using gas reformation technology with carbon capture and storage (CCS).

The captured carbon would be fed through the proposed Zero Carbon Humber onshore pipeline, part of the East Coast Cluster, recently selected as one of two carbon capture and storage schemes to receive initial government support under the Government’s Cluster Sequencing Process.

The Humber Hub Blue Project recently passed the eligibility criteria for Phase-2 of the Government’s Cluster Sequencing Process. Successful projects which could be eligible for Government funding will be shortlisted from May 2022. Phase-2 projects are expected to take final investment decisions from 2024 to then be operational from 2027.

Blue hydrogen production at Killingholme could see the capture of approximately 1.6 million metric tonnes (Mt) of carbon per year through CCS, making a significant contribution to the UK Government’s target to capture 10Mt of carbon per year by 2030. . . .

Uniper is also a partner in the Zero Carbon Humber project to develop the necessary carbon dioxide pipeline transport for blue hydrogen production. As part of the East Coast Cluster the captured carbon dioxide will be stored permanently offshore in the Northern Endurance Partnership’s facility in the UK’s North Sea.

Uniper continues to develop a separate green hydrogen project, using electrolytic hydrogen production technology, as part of the overall Humber Hub development at Uniper’s Killingholme site. Uniper, along with its project partners, will shortly complete the Project Mayflower feasibility study, part funded by the Department for Transport’s Clean Maritime Demonstration Competition, administered by InnovateUK, looking at the decarbonization of port related activities at the Port of Immingham.


BC to open office to accelerate hydrogen deployment
https://www.greencarcongress.com/2022/0 ... 14-bc.html

The Canadian province of British Columbia is establishing an office to expand hydrogen deployment rapidly and to streamline projects from proposal to construction. The BC Hydrogen Office will work with federal and local governments to help attract investments and simplify the multi-jurisdictional review and permitting processes.

There are already 40 hydrogen projects proposed or under construction in BC with more on the way. These projects represent $4.8 billion in proposed investment in the province. Many are small or medium-sized projects to provide local hydrogen supply or solutions, but some are major investments, including some of the largest proposed green hydrogen-production projects in the world. . . .

In 2021, British Columbia became the first province in Canada to release a comprehensive hydrogen strategy. Part of CleanBC, the BC Hydrogen Strategy includes 63 actions for government, industry and innovators to take over the short term (2020-25), medium term (2025-30) and long term (2030 and beyond). These include:

incentivizing the production of renewable and low-carbon hydrogen;

developing regional hydrogen hubs where production and demand are co-located;

financial supports for deploying fuel cell electric vehicles and infrastructure;

expanding the use of hydrogen across different industrial sectors and applications;

promoting the adoption of hydrogen in areas where it is most cost-effective in terms of emission reductions;

creating the B.C. Centre for Innovation and Clean Energy to drive the commercialization of new hydrogen technology; and

establishing ambitious carbon-intensity targets and a regulatory framework for carbon capture and storage.

BC has the resources to produce both green and blue hydrogen with low carbon intensity. More than 98% of BC’s electricity is renewable, allowing the production of green hydrogen via electrolysis. BC also has low-cost natural gas reserves, significant geological storage capacity and expertise in carbon capture and storage (CCS) technology, providing the potential to produce blue hydrogen from natural gas with adequate and permanent CCS.

Immediate priorities are to:

scale-up green hydrogen production using the abundant supply of clean, renewable electricity; and

establish a regulatory framework for CCS to enable blue hydrogen production while ensuring it has similar or lower emissions.

More than 50% of Canada’s hydrogen and fuel-cell companies are in BC; the province accounts for about 60% of Canada’s research investment in hydrogen and fuel-cell development.

By mixing in hopium into the carbon capture tech of course! Nothing says "possible" like pixie dust after all.

Edit: explaining further for GRA's sake. No carbon capture tech has proven to be even carbon neutral in their implementation (even planting trees, since that takes years to take effect), let alone the carbon negative scale needed to offset whatever carbon-intensive business they were supposed to "offset".
