Industry overview 2 13
H 2 Introduction to green hydrogen Hydrogen is broadly applicable to multiple end markets, and can be obtained as a gas through fossil fuels (Grey, Blue), nuclear power (Pink H2) or renewable sources (Green H2) What is hydrogen? Main types by source of energy utilized Applications and end markets Hydrogen (H ) is a clean, chemical energy carrier 2 alternative to methane (natural gas) On the planet, vast numbers of hydrogen atoms are contained in water, plants, animals and humans – It's the most abundant chemical element in the universe, contributing ~75% of total mass – However, despite being present in nearly all molecules in living things, it’s very scarce as a gas (less than one part per million by volume) Hydrogen can be produced from a variety of energy sources, such as natural gas, nuclear power, biogas and renewable power like solar and wind Hydrogen can be obtained through a process called electrolysis, which consists of using electricity to split water into oxygen and hydrogen H2O Electrolysis O2 Oxygen Hydrogen H2 O2 H2 - Grey hydrogen Hydrogen produced from natural gas using steam methane reforming (SMR) Natural gas CO2 H2 Blue hydrogen Grey hydrogen, but with carbon capture utilization and storage techniques applied Green hydrogen “Clean hydrogen,” generated from renewable energy, using water as a feedstock for electrolysis Natural gas H2 CO 2 Carbon capture (CCS) O2 Water H2 Renewable energy Hydrogen H2 Mobility Used as a substitute for fossil fuels in fuel cell cars, trucks, planes, trains, etc. Heat and power Power generation for grid, power buffering and heat for residential and industrial uses Agriculture Converted to ammonia and used in fertilizers and crop nutrients Source: Hydrogen Council, US Department of Energy, McKinsey, Bloomberg Industrial applications Used for steel production, hydrocracking, hydrogenation and synthetic gas Hydrogen is compressed and stored underground in tanks or caverns, to be used in the future Seasonal storage Pink hydrogen Hydrogen produced using electrolysis powered by nuclear energy O2 Water Nuclear energy 13
Regulatory support schemes Strong regulatory support worldwide (focus on H2B2’s core markets) United States Bipartisan Infrastructure Law includes $9.5bn for clean H2 initiatives ($8bn earmarked for Regional Clean H2 Hubs) Inflation Reduction Act (IRA) provides green H2 with substantial investment or production tax credits $3/kg green hydrogen tax credit supporting H2 production Europe REPowerEU sets a target of 10mm tons of domestic green H2 production and 10mm tons of imports by 2030 European Commission (EC) announced the creation of a €3bn European H2 bank in September 2022 EC has also proposed an upper subsidies capped at €4/kg for green hydrogen projects Target of 50% of all H2 demand in industry from renewable origin by 2030 Latin America Colombia: target of 1-3GW of electrolysis capacity (40% low-carbon) by 2030 Chile: 21% of its 2050 carbon neutrality target using green hydrogen (25GW by 2030) Uruguay: target of 1mm tons per annum of green H2 production by 2040 India Adopted net zero by 2070 in 2021 Committed to non-fossil energy capacity of 500GW by 2030 155GW new non-hydro capacity for green hydrogen production by 2030 25-year waiver on transmission charges for renewable power used by electrolyzers Japan In April 2023, the government of Japan published a draft to revise the Basic Hydrogen Strategy The draft includes a target of 12mm tons hydrogen supply by 2040 The plan also mentions JPY 15tn government and private investments to drive the adoption of the hydrogen economy Source: ARUP, Infrastructure Investment and Jobs Act Public Law No. 117-58, Inflation Reduction Act Public Law No. 117-169 16

Source: Company information, ARUP (1) Arup working under its capacity as vendor due diligence provider to H2B2 Electrolysis Technologies H2B2 addresses challenges to development of green hydrogen There has been industry-wide attrition in green hydrogen projects due to difficulties regarding securing external funding. H2B2 is positively situated to secure project financing where others are not. Green hydrogen is a relatively expensive energy compared to many alternative energy sources. This can be a limiting factor for near-term demand and investment Governments and regulatory bodies recognize the importance of hydrogen in the energy transition and have been increasing hydrogen-specific targets globally since 2016. These targets have been supported with regulatory incentives (e.g., US IRA, EU Green Industrial Plan, among others) that have made green hydrogen economically competitive Regulation and government incentives As the near- and medium-term demand grows rapidly due to regulatory drivers and improving economics, electrolyzer supply must increase commensurately to avoid industry wide shortages and project delays Supply Chain Security Securing an offtake agreement is key to obtaining funding for green hydrogen projects. Some past projects in the industry have stalled due difficulty securing offtake agreements to support project financing Potential offtakers are concerned about investing projects where there is uncertainty regarding the consistent production of hydrogen, given the relatively new technology and largely unproven execution capabilities of most EPC providers Most players are focused either on technology (electrolyzers) or EPC, creating a technology gap/risk for financing institutions and offtakers Execution Risk H2B2 has the ability to provide production guarantees, which facilitates long-term offtake contracts. H2B2 is able to provide this due to its extensive project execution experience and vertical integration H2B2 has the necessary capacity to complete the business plan.
