Central cooling systems for large-scale green hydrogen production can be based on wet or dry cooling. But there also exist hybrid solutions. This article discusses three such solutions and considers the factors influencing the selection of cooling technology.

Water is essential for the production of green hydrogen. As the market matures, crucial questions about the use of water are starting to arise. How much water is needed? What quality is sufficient? Where should the water come from? Let’s shed some light on these fundamental questions.

Building on its expertise in polymer chemistry, Evonik has propelled itself to the forefront of innovation in gas separation membranes. Recently, the chemical giant has expanded its portfolio of high-performance membranes to drive the transition of today’s conventional energy supply to a sustainable gas economy of tomorrow. By developing the SEPURAN^® Noble membrane for hydrogen recovery and the DURAION^® membrane for green hydrogen production, the company is intensifying its efforts to drive sustainability through technological innovation.

Hydrogen plays a central role in the energy transition, and existing natural gas infrastructure is to be used for its transport and storage. TÜV SÜD assesses the integrity and service life of the pipelines intended for this purpose using fracture mechanics calculations. In doing so, the experts take into account the embrittlement of steel and factors such as crack initiation and crack growth under hydrogen atmospheres

Hydrogen addresses the main challenges towards a sustainable energy transition, but there are major problems that must be tackled. They include costs, efficiency and suitability for series production. Combining the expertise needed for large-scale implementation, CellForm develops the production of the key component of electrolysers and fuel cells, the bipolar plate, in order to disruptively address the current deficits of green hydrogen technology.

When it comes to bringing down the costs of green hydrogen production, maximizing plant efficiency is key. Compressors and electrolyzers represent a large portion of a plant’s total power consumption. By engaging with the manufacturers of these equipment assets early in the design process, operators can reduce OPEX and improve project economics.

Generation of hydrogen from renewables has the potential to bypass grid-development bottlenecks, enable energy to be transported to the place where it is required and allow multi-day and even seasonal energy storage in the form of hydrogen gas or hydrogen carriers. These functions have led many to herald hydrogen as THE essential ingredient of a renewable energy system.

With over 130 years of history, PRUSS is a globally established company specialising in the design and manufacture of customised control valves and actuators for a wide range of industrial sectors. Building on decades of expertise in valves for hydrogen service, the company is now developing products for the rapidly growing hydrogen market.

Green hydrogen is the key to making our major industries more sustainable. For a long time, it was thought to be an unaffordable solution, but society has started to realize that there are no real alternatives if we want to stop climate change. Recent geopolitical developments have only accelerated this realization. The good news is that the cost of green hydrogen will soon start to drop – and in the long run the price will likely fall even below today’s fossil alternatives.
