MOSCOW (MRC) -- Shell Catalysts & Technologies is launching the Shell Blue Hydrogen Process, which integrates proven technologies to increase significantly the affordability of greenfield projects for “blue” hydrogen production from natural gas along with carbon capture, utilization and storage (CCUS), said Hydrocarbonprocessing.
Affordable blue hydrogen enables the decarbonization of hard-to-abate heavy industries while creating value for refiners and resource holders. Shell’s new process can reduce the levelized cost of hydrogen by 22% compared with the best the market has to offer today.
Without low-carbon hydrogen, the net-zero goals announced by governments and companies will be difficult to achieve. Currently, hydrogen production is nearly all “grey” (from hydrocarbons without CCUS). If hydrogen is to contribute to carbon neutrality, it must be produced on a much larger scale and with far lower emission levels.
Blue hydrogen production can be relatively easily scaled up to meet demand. With carbon dioxide (CO2) costing USD25–35/t, blue hydrogen becomes competitive against grey, even with its higher capital costs. And green hydrogen, produced from the renewable-energy powered electrolysis of water, may still be more than double the price of blue hydrogen by 2030[i] and not achieve cost parity until about 2045.
This analysis is based on conventional steam methane reforming (SMR) and auto-thermal reforming (ATR) technologies. The availability of the Shell Blue Hydrogen Process, which integrates proprietary Shell gas partial oxidation (SGP) technology with ADIP ULTRA solvent technology, further improves blue hydrogen economics.
A key advantage of SGP technology over ATR is that the partial oxidation reaction does not require steam. Instead, high-pressure steam is generated, which satisfies the steam demands of the process and some other power consumers. There is also no need for feed gas pretreatment, which simples the process line-up. And SGP gives refiners greater feed flexibility, as it is more robust against feed contaminants and can thus accommodate a large range of natural gas qualities.
Compared with ATR, SGP technology gives a 22% lower levelized cost of hydrogen from: 17% lower capital expenditure (higher operating pressure giving smaller hydrogen compressor and CO2 capture and compressor units); and 34% lower operating expenditure (excluding the natural gas feedstock price) from reduced compression duties and more steam generation.
When compared with SMR, SGP technology leads to even greater hydrogen production cost savings from both the capital and operating expenditure perspectives.
As MRC informed before, Royal Dutch Shell plc. said earlier this month that its petrochemical complex of several billion dollars in Western Pennsylvania is about 70% complete and in the process to enter service in the early 2020s. The plant’s costs are estimated to be USD6-USD10 billion, where ethane will be transformed into plastic feedstock. The facility is equipped to produce 1.5 million metric tons per year (mmty) of ethylene and 1.6 mmty of polyethylene (PE), two important constituents of plastics.
Ethylene and propylene are feedstocks for producing PE and polypropylene (PP).
According to MRC's ScanPlast report, Russia's estimated PE consumption totalled 1,496,500 tonnes in the first eight months of 2020, up by 5% year on year. Shipments of all ethylene polymers increased, except for linear low desnity polyethylene (LLDPE). At the same time, PP shipments to the Russian market reached 767,2900 tonnes in the eight months of 2020 (calculated using the formula - production minus exports plus imports - and not counting producers' inventories as of 1 January, 2020). Supply increased exclusively of PP random copolymer.
Royal Dutch Shell plc is an Anglo-Dutch multinational oil and gas company headquartered in The Hague, Netherlands and with its registered office in London, United Kingdom. It is the biggest company in the world in terms of revenue and one of the six oil and gas "supermajors". Shell is vertically integrated and is active in every area of the oil and gas industry, including exploration and production, refining, distribution and marketing, petrochemicals, power generation and trading.
