The global push for decarbonization has positioned green hydrogen as one of key components of the energy transition. However, large-scale deployment remains constrained by high costs, fragmented supply chains, and long project timelines. Addressing these barriers, Rely – a joint venture between Technip Energies and John Cockerill – has introduced an innovative approach that combines standardization, seamless integration, and a fully wrapped project delivery model for green hydrogen and power-to-X. With its flagship product, Clear100+, Rely is transforming how green hydrogen plants are designed, built, and operated, making industrial-scale hydrogen production more efficient, cost-effective, and reliable.

The global hydrogen market is facing major challenges. While the demand for green hydrogen is projected to reach at least 25 million metric tons by 2050, the available production capacity to reach this goal remains insufficient. Electrolyzers, the key plants for hydrogen production, are still not built on the necessary scale. At the same time, Power-to-X technologies are unlocking revolutionary methods to transform green energy into sustainable fuels, chemicals, or ship propellants. Innovative and scalable engineering processes are vital for these technologies to succeed. Aucotec’s data-centric platform Engineering Base offers a tailor-made solution, demonstrating why structured data is the key for the Power-to-X and hydrogen industries and further business cases including predictive maintenance and AI analytics.

Methanol is gaining prominence as a key player in the transition to a more sustainable future, particularly in sectors such as shipping, chemicals, and aviation, with the latter showing promise as an end use via the methanol-to-jet route. This synthetic compound is classified as an RFNBO (Renewable Fuel of Non-Biological Origin) when produced using hydrogen generated from renewable electricity and carbon dioxide captured from various sources. In this article, we will address the most relevant parameters of e-methanol plants and their coupling with renewable hydrogen production.

Hydrogen storage remains a key challenge for advancing the hydrogen economy. While current technologies, such as high-pressure gas and cryogenic liquid storage, have served various applications, they face limitations in cost, volumetric and gravimetric efficiencies, and jurisdictional restrictions related to safety. Solid-state hydrogen storage using reticular materials, such as Metal-Organic Frameworks (MOFs), offers a promising alternative at low pressures and ambient temperatures without compromising storage capacity. This article explores how hydrogen storage based on reticular materials compares to conventional methods and examines its potential to revolutionize the hydrogen value chain.

The steel industry faces mounting pressure to reduce its environmental impact. A critical step in decarbonizing steel lies in removing fossil fuels across all stages of production. In September 2023, Swedish steel manufacturer Ovako opened the world’s first plant to produce fossil-free hydrogen for heating steel before rolling. This is a significant step in helping the company meet its ambitious targets for a sustainable future.

Greene Tweed, a family-owned company with origins dating back to 1863, has consistently demonstrated leadership in advanced materials and high-performance solutions across diverse industries. Headquartered in Lansdale, Pennsylvania, U.S., Greene Tweed specializes in designing and manufacturing high-performance elastomers, composites, and engineered components that tackle some of the most demanding challenges in hydrogen applications and beyond. With a steadfast commitment to innovation, the company is well-positioned to drive technological advancements that support the global transition to clean energy.

Global electricity demand is projected to grow substantially, with the economies of India and China seeing the greatest increases. Many factors come into play, including the proliferation of electric vehicles, data center expansions driven by artificial intelligence, the conversion to highly efficient heat pumps for heating, and the overall transition to decarbonize.

The H-Battery represents a breakthrough in renewable energy storage, building on the alkaline fuel cell (AFC) technology previously used on NASA’s Apollo and Columbia missions. Despite its initial success, AFC has been largely forgotten in terrestrial applications due to its sensitivity to CO₂, which compromises its performance on Earth. ShipTown has now pioneered a solution that overcomes this limitation, allowing the AFC to tolerate CO₂ contamination. Additionally, the H-Battery is a reversible system that functions as both a fuel cell and an electrolysis cell, with a combined round-trip efficiency of around 50%.

One of the key applications of green hydrogen is in the production of green ammonia, which can significantly reduce the carbon footprint of nitrogen-based fertilizers. By integrating advanced technologies such as Stamicarbon’s NX STAMI Green Ammonia™ process, small- to medium-scale plants can efficiently produce ammonia while lowering emissions. This shift offers an opportunity to decarbonize fertilizer production, contributing to more sustainable agricultural practices and helping meet the growing global demand for food in an environmentally responsible way.
