Transcript

Today we’re diving into three groundbreaking hydrogen developments that are shaping the global hydrogen economy. We’ll review Australia’s A$432 million investment in green hydrogen, Europe’s €2.5 billion cross-border hydrogen pipeline, and a pioneering bio-stimulated hydrogen trial in California, weaving in a deep dive into biohydrogen’s potential. Each story will explore its implications for global production methods and the broader energy transition. All of this on todays hydrogen podcast.

We begin in Australia, where on July 4, 2025, Reuters reported that the government is investing A$432 million, equivalent to US$283 million, in Orica’s Hunter Valley Hydrogen Hub, the world’s largest explosives manufacturer. This project, part of Australia’s A$2 billion Hydrogen Headstart Program, deploys a 50-megawatt electrolyzer powered by renewable energy to produce hydrogen for industrial applications at Orica’s Kooragang Island facility in New South Wales. The initiative targets decarbonization of industrial processes, which account for 23.56% of global hydrogen consumption, according to Grand View Research. Despite challenges—Origin Energy and Fortescue withdrew from similar projects, and Queensland’s A$12.5 billion CQ-H2 plant collapsed—Australia’s commitment includes an additional A$814 million in grants to projects like Copenhagen Infrastructure Partners’ Murchison initiative, showcasing robust policy support. Producing hydrogen via electrolysis at US$3 to US$5 per kilogram with a carbon intensity of 0.1 to 0.5 kilograms of CO2 equivalent per kilogram, as estimated by the DOE, this project competes with hydrogen derived from hydrocarbons, which costs US$1 to US$2 per kilogram, according to the IEA.

Global Implications: Australia’s A$432 million investment demonstrates how substantial subsidies can accelerate the adoption of cleaner hydrogen production methods worldwide. By offsetting the high capital costs of electrolyzers, which range from US$1,000 to US$2,000 per kilowatt according to BloombergNEF, this approach enables hydrogen from renewable sources to challenge the dominance of steam methane reforming with carbon capture, which produces hydrogen at US$1 to US$2 per kilogram with a carbon intensity of 0.5 to 1 kilogram of CO2 equivalent per kilogram, widely used in Asia. This model inspires regions like the Middle East, where Saudi Arabia’s NEOM project aims to produce 4 million tons of hydrogen annually by 2030, and Europe, which targets 40 gigawatts of electrolysis capacity by 2030, according to the IEA. Nuclear-powered hydrogen production in countries like France and Japan, costing US$2 to US$4 per kilogram with a carbon intensity of 0.1 to 0.5 kilograms of CO2 equivalent, provides a complementary low-carbon option, as noted by the DOE. Similarly, methane pyrolysis in Canada and Australia, also at US$1 to US$2 per kilogram, offers flexibility by generating valuable carbon byproducts, with the carbon black market projected to reach US$12.8 billion by 2032, per DataHorizon Research. However, global infrastructure gaps, such as the high cost of pipelines at US$1 to US$2 million per mile, pose challenges, but Australia’s planned 1,400-kilometer hydrogen network sets a precedent for enabling hydrogen to support industrial decarbonization globally, according to the IEA.

Next, we head to Europe, where on July 3, 2025, Reuters reported that France’s Natran, a unit of Engie, along with Terega and Spain’s Enagas, have formed a joint venture to develop the Barmar pipeline, a Barcelona-to-Marseille underwater link. This pipeline is a key component of the €2.5 billion H2Med project, designed to transport 2 million tons of renewable hydrogen annually by 2030, connecting Portugal, Spain, France, and Germany, and meeting 10% of the European Union’s projected hydrogen demand, according to the IEA. With Enagas holding a 50% stake, Natran 33.3%, and Terega 16.7%, Barmar addresses critical transport bottlenecks, enabling hydrogen to reach industrial and energy hubs like Germany’s Ruhr region. Transporting hydrogen through pipelines costs €2 to €3 per kilogram, supporting Europe’s ambitious target of 40 gigawatts of electrolysis capacity by 2030, backed by €992 million from the EU Hydrogen Bank, per BloombergNEF.

Global Implications: The €2.5 billion Barmar pipeline highlights the pivotal role of transport infrastructure in scaling the global hydrogen economy. In Asia, where Japan and South Korea aim to import 5 to 10 million tons of hydrogen annually by 2050, similar pipeline networks, costing US$1 to US$2 million per mile, are essential, according to McKinsey. The Middle East’s Gulf Cooperation Council could develop regional networks to export hydrogen produced from renewable sources, as projected by BloombergNEF. Steam methane reforming with carbon capture, producing hydrogen at US$1 to US$2 per kilogram with a carbon intensity of 0.5 to 1 kilogram of CO2 equivalent in countries like China and India, relies on pipelines to connect production to demand centers, per Nature Energy. Methane pyrolysis in Australia and Canada, also at US$1 to US$2 per kilogram, supports diverse applications by generating carbon byproducts for a market projected to reach US$12.8 billion by 2032, per DataHorizon Research, but requires robust transport infrastructure. Nuclear-powered hydrogen in France and Canada, costing US$2 to US$4 per kilogram, ensures a stable supply for pipeline networks, according to the DOE. Globally, investments of US$50 to US$100 billion in pipelines by 2035 are critical to enable hydrogen to decarbonize industries and energy systems worldwide, per the IEA, with Barmar serving as a pioneering model.

Finally, we head to California, where on June 24, 2025, Gold H2, a subsidiary of Cemvita, announced the world’s first successful subsurface bio-stimulated hydrogen production trial in the San Joaquin Basin, according to their press release. By injecting microbes and nutrients into a depleted oil reservoir, Gold H2 achieved hydrogen concentrations of 400,000 parts per million, or 40% of the gas stream, using a huff-and-puff method in partnership with ChampionX, per Global Hydrogen Review. The trial leveraged existing infrastructure, avoiding new drilling or energy-intensive facilities, with targeted production costs below US$0.50 per kilogram and a carbon intensity of 0 kilograms of CO2 equivalent per kilogram, as estimated by the DOE. Let’s explore biohydrogen’s background, production, and economics before diving into its global implications.

Biohydrogen Background and Production: Biohydrogen is produced biologically using microorganisms like bacteria or algae through processes such as dark fermentation, photo-fermentation, or bio-stimulation, according to ScienceDirect. Dark fermentation employs bacteria, such as Clostridium, to break down organic matter, yielding 2 to 4 moles of hydrogen per mole of glucose at temperatures of 30 to 50 degrees Celsius, as noted by the National Renewable Energy Laboratory. Photo-fermentation uses photosynthetic bacteria to achieve higher yields of 6 to 8 moles of hydrogen per mole of substrate but requires light, per the IEA. Gold H2’s bio-stimulation approach injects microbes and nutrients into depleted reservoirs to convert residual hydrocarbons into hydrogen, achieving a 40% hydrogen purity in the gas stream, as reported by Hart Energy. This method avoids the US$10 to US$50 million drilling costs associated with traditional natural hydrogen production, requiring only US$1 to US$5 million in microbial and nutrient inputs per site, with CO2 byproducts, accounting for 20% of costs, reinjected into the reservoir, per the Journal of Petroleum Technology.

Biohydrogen Economics: Biohydrogen’s production costs, ranging from US$0.50 to US$0.80 per kilogram, undercut steam methane reforming with carbon capture at US$1 to US$2 per kilogram and hydrogen from electrolysis at US$3 to US$5 per kilogram, according to the DOE. Revenue streams include hydrogen sales and carbon credits, valued at US$50 to US$100 per ton of CO2 avoided, with biogas byproducts fetching US$200 to US$300 per ton, per BloombergNEF and NREL. California’s San Joaquin Basin reservoirs could yield up to 250 billion kilograms of hydrogen, according to Gold H2, though the 40% hydrogen purity requires additional purification costing US$0.10 to US$0.20 per kilogram, per BloombergNEF. Scaling to commercial production of 0.5 to 1 million tons annually by 2035 requires investments of US$1 to US$2 billion, with research and development costs of US$5 to US$10 million per site, according to the IEA.

Global Implications: Gold H2’s trial in the San Joaquin Basin positions biohydrogen as a transformative option for the global energy transition, offering a low-cost, low-carbon alternative. Depleted oil and gas reservoirs in regions like Canada’s Alberta, Russia’s Siberia, and the Middle East’s Persian Gulf could produce 1 to 2 million tons of hydrogen annually by 2035 at US$0.50 to US$0.80 per kilogram, according to the IEA, supporting a wide range of industrial and energy applications. Biohydrogen’s minimal reliance on subsidies, unlike hydrogen from electrolysis, which depends on incentives like the U.S.’s 45V credit of up to US$3 per kilogram or Europe’s €992 million Hydrogen Bank, enhances its adoption in cost-sensitive markets, per BloombergNEF.
