De-mystifying economic policy for Hydrogen – “The 5 Levers” with GHD

De-mystifying economic policy for Hydrogen – “The 5 Levers”, with GHD Introduction to Ariel: Ariel Elboim a Senior Advisor for GHD working in the future energy market. A consultant for 10 years, Ariel has worked on the decarbonisation of infrastructure, and renewable energy projects across various sectors, including energy, water and transport. For the past 5 years, his focus has been dedicated to accelerating the growth of the hydrogen industry in Australia. He plays an active role not only through his project work for both private and public clients but also through his engagement with industry, including his position as H2Q Hydrogen Queensland Policy Advocacy Taskforce Lead. 1.45 - About GHD & Ariel's work GHD is a globally recognised organisation operating in the markets of engineering, architecture, digital, water, energy, environment, and transport. Above 11,000 employees across 5 continents and 120+ offices. Over the last 4 years, Ariel has been working holistically to accelerate the growth of the hydrogen industry in Australia, and that's been looking at strategic, tactical, operational projects, and more recently, at policy and policy mechanisms and how they can be conducive to the growth of the industry in Australia. 3.00 - The work H2Q Hydrogen Queensland is doing to help translate what industry sentiment is and how that can help inform government policy. They have been doing a lot of engagement and report writing over the last year with a white paper that was released over Christmas. 4.15 -Summary of the 5 levers & examples around the world Lever # 1 - Tax Regulation What can the government do in terms of regulatory standards and requirements to influence proponent behaviour, and what kind of tax levers can they use to influence taxpayers' behaviour? Regulatory standards and requirements that the government can implement to influence behaviour, or what kind of tax incentives or penalties can the government implement to also influence behaviour? 06.00 - Carbon prices around the world & the Safeguard Mechanism 08.20 - Lever #2 - Tax credits & subsidies Tax credits and subsidies are an incentive-based policy instrument that provides market-compatible forms of direct government intervention. 09.00 - U. S. Inflation Reduction Act This offers a tax credit of up to $3 per kilogram of hydrogen produced. That $3 per kilogram is based on the carbon intensity of the product. 10.06 - What can Australia do, even without having such ‘deep pockets’ as the US? 11.20 - Lever #3 - Market based schemes Market-based schemes are interesting because they're an amalgamation of different mechanisms and they usually consist of a pull mechanism or a lever that tries to pull investment into the market, and a push mechanism, so it pushes proponents to do something. 12.30 - Lever # 4 - Contracts for Difference This lever is getting a lot of attention across the world at the minute, especially in the hydrogen space. CFDs, Contracts for Differences, are financial contracts between a supplier and a purchaser of energy, provided a certain price. The Contract for Difference stipulates that the purchaser will pay the seller the difference between the market value at the time of contracting. Essentially a market price is agreed upon, usually called the strike price, and this is based on several factors. It could be the level of CO2 emissions that are being abated. It could be the cost of the fossil fuel plus a green premium, whatever the market decides is a strike price, but everyone agrees that's the baseline. 14.45 - Review periods for Contracts for Difference "Contracts for Difference usually last for about 10, 12, 15 years and by that point, the market will have readjusted to an equilibrium. And then you reassess it." 17.00 - "The biggest issue in the hydrogen space at the minute and the reason projects aren't getting past FID, or to FID, is because the prem

Before joining the company in 2014, Mr. Thomas worked 8 years in the solar photovoltaic sector in Europe. Mr. Thomas holds a Master’s Degree in Business Administration and in Renewable Energy. Michael Bartsch is the Regional Sales and Business Development manager for water electrolysis at Accelera by Cummins. Before joining the company in 2020, Mr Bartsch worked for 26 years in a mixture of Mining, Petroleum, Water Treatment and Geothermal sectors. Mr. Bartsch is an Industrial Chemist with formal qualifications in Science, Business Administration and Energy. Cummins is more than 104 years old, specialising in engines and gensets with 70,000 people worldwide. Accelera is a brand within the company that hosts all the new technologies and has five main businesses and between 2000-3,000 employees 2.30 – The main technologies within Accelera - Electrolysers - Fuel cells - Electrified components - Power train systems - Traction systems 4.00 – Explanation of the different types of electrolysers - Alkaline- PEM- Solid oxide- Anion Exchange Membrane 06.30 - PEM - Proton Exchange Membrane. 08.15 - Solid oxide and Anion Exchange Membrane 09.15 - Concerns about the catalyst being used in PEM technology 10.44 - Sizes of electrolysers that Accelera Manufacture The products are PEM technology. 30 bar pressure. HyLyzer 500, 1000 and 5000. 13.00 - Interesting and challenging projects across the globe: The Quebec project is commercial, meaning running the electrolyser daily. The hydrogen is liquefied and then delivered by Air Liquide to industrial customers. 15.30 – Emergence of much larger projects across the globe Customers are now leaning more toward double-digit and triple-digit production. 16.26 - Learnings through the project in Canada 19.17 - Australian market compared to the rest of the world The speed to market in the other locations is by far faster at the moment. In Australia, there is a push for regional codes and standards adoption. When products have to be modified before they can be introduced so there's a lag factor there in terms of being able to deploy or modify existing designs for them to be accepted. “We will initially be importing products mainly from Europe, but it'll get to a point where the project size here in Australia is big enough to justify local manufacturing.” 24.15 – Manufacturing of the Electrolysers “We've been working a lot on designing new processes and we are implementing them in the different factories. We have started already in Belgium, which was an existing factory. We have built another in Spain that will start production in the first quarter of next year. We will be using this flow-based manufacturing. It is super interesting because it gives us a lot of flexibility.” 25.00 – Current challenges - The business case of producing hydrogen; in many cases, it is more expensive than the conventional way of producing hydrogen with natural gas. - The size is increasing, and there is an increased link with renewable power which also brings challenges. - Electrolyser technologies are new so companies need to get used to it - Infrastructure challenges - hydrogen storage and pipelines - Execution capability Regulation and policy can be used to play an important role in giving a premium value to hydrogen in comparison to the incumbent technology…Where there is a lack of policy, there is a high uncertainty on those projects, meaning that it is difficult for us to anticipate and forecast the market. 33.13 - Which skillsets will be sought after in the coming years? 35.00 – Advancements in technology -
