Green hydrogen

Last updated

Green hydrogen (GH2 or GH2) is hydrogen produced by the electrolysis of water, using renewable electricity. [1] [2] Production of green hydrogen causes significantly lower greenhouse gas emissions than production of grey hydrogen, which is derived from fossil fuels without carbon capture. [3]

Contents

Green hydrogen's principal purpose is to help limit global warming to 1.5 °C, reduce fossil fuel dependence by replacing grey hydrogen, and provide for an expanded set of end-uses in specific economic sectors, sub-sectors and activities. These end-uses may be technically difficult to decarbonize through other means such as electrification with renewable power. Its main applications are likely to be in heavy industry (e.g. high temperature processes alongside electricity, feedstock for production of green ammonia and organic chemicals, as direct reduction steelmaking), long-haul transport (e.g. shipping, aviation and to a lesser extent heavy goods vehicles), and long-term energy storage. [4]

As of 2021, green hydrogen accounted for less than 0.04% of total hydrogen production. [5] Its cost relative to hydrogen derived from fossil fuels is the main reason green hydrogen is in less demand. [6] For example, hydrogen produced by electrolysis powered by solar power was about 25 times more expensive than that derived from hydrocarbons in 2018. [7] By 2024, this cost disadvantage had decreased to approximately 3x more expensive. [8]

Definition

Most commonly, [9] green hydrogen is defined as hydrogen produced by the electrolysis of water, using renewable electricity. [1] [2] In this article, the term green hydrogen is used with this meaning.

Precise definitions sometimes add other criteria. The global Green Hydrogen Standard defines green hydrogen as "hydrogen produced through the electrolysis of water with 100% or near 100% renewable energy with close to zero greenhouse gas emissions." [10] [11]

A broader, less-used [9] definition of green hydrogen also includes hydrogen produced through various other methods that produce relatively low emissions and meet other sustainability criteria. For example, these production methods may involve nuclear energy or biomass feedstocks. [9] [12] [13]

Electrolysis

Hydrogen can be produced from water by electrolysis. Electrolysis powered by renewable energy is carbon neutral. The business consortium Hydrogen Council said that, as of December 2023, manufacturers are preparing for a green hydrogen expansion by building out the electrolyzer pipeline by 35 percent to meet the needs of more than 1,400 announced projects. [14]

Biochar-assisted

Biochar-assisted water electrolysis (BAWE) reduces energy consumption by replacing the oxygen evolution reaction (OER) with the biochar oxidation reaction (BOR). An electrolyte dissolves the biochar as the reaction proceeds. A 2024 study claimed that the reaction was 6x more efficient than conventional electrolysis, operating at <1 V, without O2 production using ~250 mA/gcat H2 current at 100% Faradaic efficiency. The process could be driven by small-scale solar or wind power. [15]

Cow manure biochar operated at only 0.5 V, better than materials such as sugarcane husks, hemp waste, and paper waste. Almost 35% of the biochar and solar energy was converted into hydrogen. Biochar production (via pyrolysis) is not carbon neutral. [15]

Uses

Hydrogen has the most potential to reduce greenhouse gas emissions when used in chemical production, refineries, international shipping, and steelmaking, according to the International Renewable Energy Agency. IRENA maturity of hydrogen solutions 2022.svg

There is potential for green hydrogen to play a significant role in decarbonising energy systems where there are challenges and limitations to replacing fossil fuels with direct use of electricity.

Hydrogen fuel can produce the intense heat required for industrial production of steel, cement, glass, and chemicals, thus contributing to the decarbonisation of industry alongside other technologies, such as electric arc furnaces for steelmaking. [17] However, it is likely to play a larger role in providing industrial feedstock for cleaner production of ammonia and organic chemicals. [4] For example, in steelmaking, hydrogen could function as a clean energy carrier and also as a low-carbon catalyst replacing coal-derived coke. [18]

Hydrogen used to decarbonise transportation is likely to find its largest applications in shipping, aviation and to a lesser extent heavy goods vehicles, through the use of hydrogen-derived synthetic fuels such as ammonia and methanol, and fuel cell technology. [4] As an energy resource, hydrogen has a superior energy density (39.6 kWh) versus batteries (lithium battery: 0.15-0.25 kWh). [19] For light duty vehicles including passenger cars, hydrogen is far behind other alternative fuel vehicles, especially compared with the rate of adoption of battery electric vehicles, and may not play a significant role in future. [20]

Green hydrogen can also be used for long-duration grid energy storage, [21] [22] and for long-duration seasonal energy storage. [23] It has been explored as an alternative to batteries for short-duration energy storage. [24] [ better source needed ]

Green methanol

Green methanol is a liquid fuel that is produced from combining carbon dioxide and hydrogen (CO2 + 3 H2 → CH3OH + H2O) under pressure and heat with catalysts. It is a way to reuse carbon capture for recycling. Methanol can store hydrogen economically at standard outdoor temperatures and pressures, compared to liquid hydrogen and ammonia that need to use a lot of energy to stay cold in their liquid state. [25] In 2023 the Laura Maersk was the first container ship to run on methanol fuel. [26] Ethanol plants in the midwest are a good place for pure carbon capture to combine with hydrogen to make green methanol, with abundant wind and nuclear energy in Iowa, Minnesota, and Illinois. [27] [28] Mixing methanol with ethanol could make methanol a safer fuel to use because methanol doesn't have a visible flame in the daylight and doesn't emit smoke, and ethanol has a visible light yellow flame. [29] [30] [31] Green hydrogen production of 70% efficiency and a 70% efficiency of methanol production from that would be a 49% energy conversion efficiency. [32]

Market

As of 2022, the global hydrogen market was valued at $155 billion and was expected to grow at an average (CAGR) of 9.3% between 2023 and 2030. [33] Of this market, green hydrogen accounted for about $4.2 billion (2.7%). [34] Due to the higher cost of production, green hydrogen represents a smaller fraction of the hydrogen produced compared to its share of market value. The majority of hydrogen produced in 2020 was derived from fossil fuel. 99% came from carbon-based sources. [35] Electrolysis-driven production represents less than 0.1% of the total, [36] of which only a part is powered by renewable electricity.

The current high cost of production is the main factor limiting the use of green hydrogen. A price of $2/kg is considered by many to be a potential tipping point that would make green hydrogen competitive against grey hydrogen. [37] [38] [39] It is cheapest to produce green hydrogen with surplus renewable power that would otherwise be curtailed, which favours electrolysers capable of responding to low and variable power levels (such as proton exchange membrane electrolysers). [40] : 5 

The cost of electrolysers fell by 60% from 2010 to 2022, [41] and green hydrogen production costs are forecasted to fall significantly to 2030 and 2050, [40] : 26  driving down the cost of green hydrogen alongside the falling cost of renewable power generation. [42] [43] : 28  Goldman Sachs analysis observed in 2022, just prior to Russia's invasion of Ukraine that the "unique dynamic in Europe with historically high gas and carbon prices is already leading to green H2 cost parity with grey across key parts of the region", and anticipated that globally green hydrogen achieve cost parity with grey hydrogen by 2030, earlier if a global carbon tax were placed on grey hydrogen. [44]

As of 2021, the green hydrogen investment pipeline was estimated at 121 gigawatts of electrolyser capacity across 136 projects in planning and development phases, totaling over $500 billion.[ dubious – discuss ] [45] If all projects in the pipeline were built, they could account for 10% of hydrogen production by 2030. [45] The market could be worth over $1 trillion a year by 2050 according to Goldman Sachs. [46] An energy market analyst suggested in early 2021 that the price of green hydrogen would drop 70% by 2031 in countries that have cheap renewable energy. [47]

Projects

Australia

In 2020, the Australian government fast-tracked approval for the world's largest planned renewable energy export facility in the Pilbara region. In 2021, energy companies announced plans to construct a "hydrogen valley" in New South Wales at a cost of $2 billion to replace the region's coal industry. [48]

As of July 2022, the Australian Renewable Energy Agency (ARENA) had invested $88 million in 35 hydrogen projects ranging from university research and development to first-of-a-kind demonstrations. In 2022, ARENA is expected to close on two or three of Australia's first large-scale electrolyser deployments as part of its $100 million hydrogen deployment round. [49]

In 2024 Andrew Forrest delayed or cancelled plans to manufacture 15 million tonnes of green hydrogen per year by 2030. [50]

Brazil

Brazil's energy matrix is considered one of the cleanest in the world. Experts highlight the country's potential for producing green hydrogen. Research carried out in the country indicates that biomass (such as starches and waste from sewage treatment plants) can be processed and converted into green hydrogen (see: Bioenergy, Biohydrogen and Biological hydrogen production). The Australian company Fortescue Metals Group has plans to install a green hydrogen plant near the port of Pecém, in Ceará, with an initial forecast of starting operations in 2022. In the same year, the Federal University of Santa Catarina announced a partnership with the German Deutsche Gesellschaft für Internationale Zusammenarbeit, for the production of H2V. Unigel has plans to build a green hydrogen/green ammonia plant in Camaçari, Bahia, which is scheduled to come into operation in 2023. Initiatives in this area are also ongoing in the states of Minas Gerais, Paraná, Pernambuco, Piauí, Rio de Janeiro, Rio Grande do Norte, Rio Grande do Sul and São Paulo. Research work by the University of Campinas and the Technical University of Munich has determined the space required for wind and solar parks for large-scale hydrogen production. According to this, significantly less land will be required to produce green hydrogen from wind and photovoltaic energy than is currently required to grow fuel from sugarcane. In this study, author Herzog assumed an electricity requirement for the electrolysers of 120 gigawatts (GW). On November 20, 2023, Ursula von der Leyen, President of the European Commission, announced support for the production of 10 GW of hydrogen and subsequently ammonia in the state of Piauí. Ammonia will be exported from there.

Canada

World Energy GH2's Project Nujio'qonik aims to be Canada's first commercial green hydrogen / ammonia producer created from three gigawatts of wind energy on the west coast of Newfoundland and Labrador, Canada. Nujio'qonik is the Mi'kmaw name for Bay St. George, where the project is proposed. Since June 2022, the project has been undergoing environmental assessment [51] according to regulatory guidelines issued by the Government of Newfoundland and Labrador.

Chile

Chile's goal to use only clean energy by the year 2050 includes the use of green hydrogen. The EU Latin America and Caribbean Investment Facility provided a €16.5 million grant and the EIB and KfW are in the process of providing up to €100 million each to finance green hydrogen projects. [52] [53]

China

In 2022 China was the leader of the global hydrogen market with an output of 33 million tons (a third of global production), mostly using fossil fuel. [54] As of 2021, several companies have formed alliances to increase production of the fuel fifty-fold in the next six years. [55]

Sinopec aimed to generate 500,000 tonnes of green hydrogen by 2025. [56] Hydrogen generated from wind energy could provide a cost-effective alternative for coal-dependent regions like Inner Mongolia. [57] As part of preparations for the 2022 Winter Olympics a hydrogen electrolyser, described as the "world's largest" began operations to fuel vehicles used at the games. The electrolyser was powered by onshore wind. [58]

Egypt

Egypt has opened the door to $40 billion of investment in green hydrogen and renewable technology by signing seven memoranda of understanding with international developers in the fields. The projects located in the Suez canal economic zone will see an investment of around $12 billion at an initial pilot phase, followed by a further $29 billion, according to the country's Planning Minister, Hala Helmy el-Said. [59]

United Arab Emirates

In 2021, in collaboration with Expo 2020 Dubai, a pilot project was launched which is the first "industrial scale", solar-driven green hydrogen facility in the Middle East and North Africa." [76]

United Kingdom

In August 2017, EMEC, based in Orkney, Scotland, produced hydrogen gas using electricity generated from tidal energy in Orkney. This was the first time that hydrogen has been created from tidal energy anywhere in the world. [77]

In March 2021, a proposal emerged to use offshore wind in Scotland to power converted oil and gas rigs into a "green hydrogen hub" which would supply fuel to local distilleries. [78]

In June 2021, Equinor announced plans to triple UK hydrogen production. [79] In March 2022 National Grid announced a project to introduce green hydrogen into the grid with a 200m wind turbine powering an electrolyser to produce gas for about 300 homes. [80]

In December 2023, the UK government announced a £2 billion fund would be setup to back 11 separate projects. The then Energy Secretary, Claire Coutinho announced the funding would be invested over a 15-year period. The first allocation round would be known as HAR1. [81] Vattenfall planned to generate green hydrogen from a test offshore wind turbine near Aberdeen in 2025. [82]

United States

The federal Infrastructure Investment and Jobs Act, [83] which became law in November 2021, allocated $9.5 billion to green hydrogen initiatives. [84] In 2021, the U.S. Department of Energy (DOE) was planning the first demonstration of a hydrogen network in Texas. [85] The department had previously attempted a hydrogen project known as Hydrogen Energy California. Texas is considered a key part of green hydrogen projects in the country as the state is the largest domestic producer of hydrogen and has a hydrogen pipeline network. [86] In 2020, SGH2 Energy Global announced plans to use plastic and paper via plasma gasification to produce green hydrogen near Los Angeles. [87]

In 2021 then New York governor Andrew Cuomo announced a $290 million investment to construct a green hydrogen fuel production facility. [88] State authorities backed plans for developing fuel cells to be used in trucks and research on blending hydrogen into the gas grid. [89] In March 2022 the governors of Arkansas, Louisiana, and Oklahoma announced the creation of a hydrogen energy hub between the states. [90] Woodside announced plans for a green hydrogen production site in Ardmore, Oklahoma. [91] The Inflation Reduction Act of 2022 established a 10-year production tax credit, which includes a $3.00/kg subsidy for green hydrogen. [92]

Public-private projects

In October 2023, Siemens announced that it had successfully performed the first test of an industrial turbine powered by 100 per cent green hydrogen generated by a 1 megawatt electrolyser. The turbine also operates on gas and any mixture of gas and hydrogen. [93]

Government support

In 2020, the European Commission adopted a dedicated strategy on hydrogen. [94] The "European Green Hydrogen Acceleration Center" is tasked with developing a €100 billion a year green hydrogen economy by 2025. [95]

In December 2020, the United Nations together with RMI and several companies, launched Green Hydrogen Catapult, with a goal to reduce the cost of green hydrogen below US$2 per kilogram (equivalent to $50 per megawatt hour) by 2026. [96]

In 2021, with the support of the governments of Austria, China, Germany, and Italy, UN Industrial Development Organization (UNIDO) launched its Global Programme for Hydrogen in Industry. [97] Its goal is to accelerate the deployment of GH2 in industry.

In 2021, the British government published its policy document, a "Ten Point Plan for a Green Industrial Revolution," which included investing to create 5 GW of low carbon hydrogen by 2030. [98] The plan included working with industry to complete the necessary testing that would allow up to 20% blending of hydrogen into the gas distribution grid by 2023. A BEIS consultation in 2022 suggested that grid blending would only have a "limited and temporary" role due to an expected reduction in the use of natural gas. [99]

The Japanese government planned to transform the nation into a "hydrogen society". [100] Energy demand would require the government to import/produce 36 million tons of liquefied hydrogen. At the time Japan's commercial imports were projected to be 100 times less than this amount by 2030, when the use of fuel was expected to commence. Japan published a preliminary road map that called for hydrogen and related fuels to supply 10% of the power for electricity generation as well as a significant portion of the energy for uses such as shipping and steel manufacture by 2050. [101] Japan created a hydrogen highway consisting of 135 subsidized hydrogen fuels stations and planned to construct 1,000 by the end of the 2020s. [102] [103]

In October 2020, the South Korean government announced its plan to introduce the Clean Hydrogen Energy Portfolio Standards (CHPS) which emphasizes the use of clean hydrogen. During the introduction of the Hydrogen Energy Portfolio Standard (HPS), it was voted on by the 2nd Hydrogen Economy Committee. In March 2021, the 3rd Hydrogen Economy Committee was held to pass a plan to introduce a clean hydrogen certification system based on incentives and obligations for clean hydrogen. [104]

Morocco, Tunisia, [105] Egypt [106] and Namibia have proposed plans to include green hydrogen as a part of their climate change agenda. Namibia is partnering with European countries such as Netherlands and Germany for feasibility studies and funding. [107]

In July 2020, the European Union unveiled the Hydrogen Strategy for a Climate-Neutral Europe. A motion backing this strategy passed the European Parliament in 2021. [108] The plan is divided into three phases. [109] From 2020 to 2024, the program aims to decarbonize existing hydrogen production. From 2024-2030 green hydrogen would be integrated into the energy system. From 2030 to 2050 large-scale deployment of hydrogen would occur. Goldman Sachs estimated hydrogen to 15% of the EU energy mix by 2050. [110]

Six European Union member states: Germany, Austria, France, the Netherlands, Belgium and Luxembourg, requested hydrogen funding be backed by legislation. [111] Many member countries have created plans to import hydrogen from other nations, especially from North Africa. [112] These plans would increase hydrogen production, but were accused of trying to export the necessary changes needed within Europe. [113] The European Union required that starting in 2021, all new gas turbines made in the bloc must be ready to burn a hydrogen–natural gas blend. [114]

In November 2020, Chile's president presented the "National Strategy for Green Hydrogen," stating he wanted Chile to become "the most efficient green hydrogen producer in the world by 2030". [115] The plan includes HyEx, a project to make solar based hydrogen for use in the mining industry. [116]

Regulations and standards

In the European Union, certified 'renewable' hydrogen, defined as produced from non-biological feedstocks, requires an emission reduction of at least 70% below the fossil fuel it is intended to replace. [117] This is distinct in the EU from 'low carbon' hydrogen, which is defined as made using fossil fuel feedstocks. [118] For it to be certified, low carbon hydrogen must achieve at least a 70% reduction in emissions compared with the grey hydrogen it replaces. [118]

In the United Kingdom, just one standard is proposed, for 'low carbon' hydrogen. Its threshold GHG emissions intensity of 20gCO2 equivalent per megajoule [119] should be easily met by renewably-powered electrolysis of water for green hydrogen production, but has been set at a level to allow for and encourage other 'low carbon' hydrogen production, principally blue hydrogen. [120] Blue hydrogen is grey hydrogen with added carbon capture and storage, which to date has not been produced with carbon capture rates in excess of 60%. [121] To meet the UK's threshold, its government has estimated that an 85% carbon capture rate would be necessary. [122]

In the United States, planned tax credit incentives for green hydrogen production are to be tied to the emissions intensity of 'clean' hydrogen produced, with greater levels of support on offer for lower greenhouse gas intensities. [123]

In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. The voltage that is needed for electrolysis to occur is called the decomposition potential. The word "lysis" means to separate or break, so in terms, electrolysis would mean "breakdown via electricity."

Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, in various ratios. The gas often contains some carbon dioxide and methane.

<span class="mw-page-title-main">Alternative fuel</span> Fuels from sources other than fossil fuels

Alternative fuels, also known as non-conventional and advanced fuels, are fuels derived from sources other than petroleum. Alternative fuels include gaseous fossil fuels like propane, natural gas, methane, and ammonia; biofuels like biodiesel, bioalcohol, and refuse-derived fuel; and other renewable fuels like hydrogen and electricity.

Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH3OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline. Methanol is safer for the environment than gasoline, is an anti-freeze agent, prevents dirt and grime buildup within the engine, has a higher ignition temperature and can withstand compression equivalent to that of super high-octane gasoline. It can readily be used in most modern engines. To prevent vapor lock due to being a simple, pure fuel, a small percentage of other fuel or certain additives can be included. Methanol may be made from fossil fuels or renewable resources, in particular natural gas and coal, or biomass respectively. In the case of the latter, it can be synthesized from CO2 (carbon dioxide) and hydrogen. The vast majority of methanol produced globally is currently made with gas and coal. However, projects, investments, and the production of green-methanol has risen steadily into 2023. Methanol fuel is currently used by racing cars in many countries and has seen increasing adoption by the maritime industry.

Electrolysis of water is using electricity to split water into oxygen and hydrogen gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient 'tanks' or 'gas bottles', hydrogen can be used for oxyhydrogen welding and other applications, as the hydrogen / oxygen flame can reach approximately 2,800°C.

Hydrogen gas is produced by several industrial methods. Nearly all of the world's current supply of hydrogen is created from fossil fuels. Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue hydrogen.

Proposed carbon-neutral fuels can broadly be grouped into synthetic fuels, which are made by chemically hydrogenating carbon dioxide, and biofuels, which are produced using natural CO2-consuming processes like photosynthesis.

<span class="mw-page-title-main">ITM Power</span>

ITM Power plc is an energy storage and clean fuel company founded in the UK in 2001. It designs, manufactures, and integrates electrolysers based on proton exchange membrane (PEM) technology to produce green hydrogen using renewable electricity and tap water. Hydrogen produced via electrolysis is used for mobility, Power-to-X, and industry.

Power-to-gas is a technology that uses electric power to produce a gaseous fuel.

<span class="mw-page-title-main">Proton exchange membrane electrolysis</span> Technology for splitting water molecules

Proton exchange membrane(PEM) electrolysis is the electrolysis of water in a cell equipped with a solid polymer electrolyte (SPE) that is responsible for the conduction of protons, separation of product gases, and electrical insulation of the electrodes. The PEM electrolyzer was introduced to overcome the issues of partial load, low current density, and low pressure operation currently plaguing the alkaline electrolyzer. It involves a proton-exchange membrane.
