Hydrogen Technology Uses

The ongoing debates on accelerated climate action at #COP28 highlight the pivotal role of #hydrogen in transitioning to net zero. Particularly for the decarbonization of hard-to-abate sectors such as steel or chemicals, a rapid ramp-up of the hydrogen economy is vital.   In Dubai, my colleagues Yvonne Ruf, Vatche Kourkejian and Uwe Weichenhain presented a thought experiment envisioning hydrogen as a key pillar of global decarbonization efforts by 2040:   ➡️ Hydrogen production will likely increase to 240 million metric tons (Mt) per year by 2040, requiring 1 TW of electrolyzer capacity. To achieve this, we need to install as much capacity each year in the 2030s as we did in the entire decade from 2020 to 2030.   ➡️ By 2040, clean hydrogen could account for two-thirds of global production. While blue hydrogen will support the decarbonization agenda, gray hydrogen will likely remain a significant part of the global mix, providing a reliable base for industries that still depend on it, especially in Asia.   ➡️ The demand for hydrogen will become increasingly diversified. Besides the manufacturing industry, which will consume almost half of the produced hydrogen, the mobility and energy sectors will also substantially contribute to demand.   Our latest study "The Roaring '30s - A clean hydrogen acceleration story" illustrates what it means to scale the entire hydrogen value chain. It features selected case studies in areas where there is still major potential to be exploited: the build-out of offshore wind, investment in hydrogen giga-projects, the construction of a large pipeline network and boosting activity in offtake sectors such as green steel and SAF.   💡 Read how the 2030s can become a decisive decade for the hydrogen industry here: https://lnkd.in/ewBRDKcX   #RolandBerger #ActForImpact

Electrolysis hydrogen production, compressed air energy storage (CAES), and Variable Renewable Energy (VRE) 🟦 Integrating variable renewable energy (VRE) into the electrical grid presents stability challenges that can be mitigated by combining hydrogen electrolysis, Compressed Air Energy Storage (CAES), and hydrogen-fired combustion turbine generators (CTG). National Energy Technology Laboratory (NETL) study emphasises that utilising underground caverns for air and hydrogen storage is highly economical where geography permits. Operating hydrogen storage at lower pressures, whether in caverns or surface vessels, reduces compression energy demands. Proton Exchange Membrane (PEM) electrolysis is energy-intensive, however, it offers a carbon-free alternative to hydrocarbons, especially when paired with 100% hydrogen-capable CTGs for utility-scale power. 🟦 Process Description: This hybrid energy storage and generation process functions as a closed-loop system that converts surplus renewable energy into storable fuels and pressurised air, later discharging them to meet peak grid demand. Phase 1: Energy Capture and Storage The process begins when the grid produces excess variable renewable energy (VRE). This surplus power is diverted to two primary functions: Hydrogen Production: A Proton Exchange Membrane (PEM) electrolyzer uses the electricity to split water into hydrogen. This fuel is produced strictly for on-site use, ensuring the facility remains independent of external hydrocarbon or ammonia supplies. Compression: Simultaneous to electrolysis, VRE powers high-pressure compressors that drive hydrogen into storage vessels and ambient air into underground salt-mined caverns. Phase 2: Power Generation and Discharge When energy demand peaks, the facility transitions from storage to generation through a synchronized discharge cycle: Expansion and Preheating: Compressed hydrogen and air are released from storage. As they flow toward the generation unit, they are preheated by an exhaust heat recovery system to increase thermal efficiency. Multi-Stage Generation: 1. The high-pressure hydrogen and air first pass through expanders, spinning turbines to generate an initial stream of electricity. 2. The preheated air and hydrogen feed into a Hydrogen-fired Combustion Turbine Generator (CTG) afterwards. 3. The CTG burns the 100% green hydrogen to produce the bulk of the facility's power output, while its hot exhaust is recirculated to provide the necessary heat for the incoming fuel and air supplies.

Hydrogen vs. Battery Buses: A European Transit Reality Check Brussels just ended its trial, Aberdeen’s buses are idle, and hydrogen costs remain multiple times higher per kilometer than battery-electric. Meanwhile, battery buses quietly scale up everywhere hydrogen gets tried. Full article: https://lnkd.in/gDY3Y4-P The story is always the same: expensive fuel, unreliable supply chains, questionable climate benefit, and fleets that stall out or shrink. Even the so-called “successes” rely on byproduct hydrogen from chemical plants and mountains of subsidies. Quick fleet reality check: • Brussels: 1 bus trial ended; pivoting fully to battery-electric. • Aberdeen: Entire fleet parked since mid-2024 due to hydrogen shortages. • Cologne: 101 buses, only works due to industrial byproduct hydrogen. • Auxerre: 5 buses, unique case with on-site green H₂ production. • Wuppertal: 10 buses from incinerated plastic-derived H₂—climate disaster. • Bolzano: 12 buses; cost per km >2x battery-electric. • Groningen/Drenthe: 30 H₂ buses, 300+ battery-electric in service or on order. • Essen/Mülheim: Buses driving 89 km to refuel. Reconsidering whole plan. • Pau: €1M annual ops cost; switching to battery-electric. • Montpellier: Cancelled 51-bus H₂ plan after realizing costs were 8x higher. • London, Birmingham, Liverpool: Hydrogen fleets capped, no growth planned. • Toulouse, Brighton/Crawley, Wiesbaden: Limited trials, shifting electric. • Hamburg: Small H₂ pilot, but 445 battery-electric buses incoming. • De Lijn (Belgium): Dismantled H₂ station, abandoned hydrogen entirely. The writing is on the wall. The EU’s infatuation with hydrogen for road transport is unraveling. Fleet after fleet is shrinking, paused, or pivoting. Hydrogen has real roles—in refining, ammonia, and fertilizers—but transit isn’t one of them. It’s time to stop throwing good euros after bad.

Japan just made a bold move that could shift the future of commercial transport. Hydrogen fuel cell vehicles have struggled to compete with diesel because of high operating costs. That challenge has slowed adoption despite clear environmental benefits. This new subsidy program offers ¥700 per kilogram of hydrogen (around $4.84) covering up to 75% of the price gap between hydrogen and diesel at 90 key stations. Here’s why it matters: • Japan aims to grow its hydrogen truck fleet from 160 today to 17,000 by 2030, a 100x increase. • This subsidy tackles the biggest hurdle: the cost difference. • Industry leaders like Toyota and Hino Motors are already testing hydrogen trucks. • Green hydrogen costs could drop by 60% by 2030 in Japan, making fuel cells even more viable. • With carbon pricing starting in 2026, diesel will get more expensive, forcing a rethink. The infrastructure and market for hydrogen-powered fleets is increasing.

Japan is accelerating its transition toward cleaner energy by integrating hydrogen into existing power systems, offering a practical bridge between fossil fuels and a fully renewable future. Instead of replacing infrastructure entirely, engineers are modifying current gas turbines to operate on a mix of hydrogen and natural gas, gradually increasing the proportion of clean fuel over time. This blended approach allows energy producers to significantly reduce carbon emissions without the need for immediate large-scale system overhauls. Hydrogen combustion produces water vapor rather than carbon dioxide, making it an attractive option for reducing environmental impact. However, challenges remain, particularly in storing and transporting hydrogen safely and efficiently, as well as managing byproducts like nitrogen oxides under high temperatures. Although still in development and testing phases, hydrogen-compatible systems represent a realistic pathway for industries that cannot transition overnight. By adapting existing infrastructure, countries can move toward sustainability without disrupting energy supply. As research progresses, hydrogen could become a key component of global energy strategies, bridging the gap between current systems and future clean technologies.

Beyond the Hype: The Strategic Role of Hydrogen & Fuel Cells in Robust Energy Management The world is moving into more sustainable energy integration, and sustainable energy systems (SES) isn't just only about adding more renewables to the grid—it's about managing intermittency, maximizing efficiency, and decarbonizing hard-to-abate sectors. Based on recent analysis, the integration of Hydrogen (H2) and Fuel Cell (FC) technologies is moving from "potential" to "paramount" in advancing global energy management strategies. So, let us breakdown  why H2 and FCs are central to the new energy paradigm: 🔹 Bypassing the Carnot Limit Fundamentally, fuel cells are electrochemical conversion devices, not heat engines. They avoid the efficiency limitations of the Carnot cycle. While electrical efficiency is high (up to 60% for SOFCs), the real value for energy managers lies in Combined Heat and Power (CHP). By utilizing waste heat, integrated FC systems can approach 85% overall energy utilization efficiency. 🔹 Strategic Decarbonization Pathways Hydrogen acts as the critical, zero-carbon energy carrier enabling two vital strategic goals: Solving Intermittency (Green H2): Coupling electrolyzers with Renewable Energy Sources (RES) provides a mechanism for long-term, seasonal grid storage—bridging the gap when solar and wind aren't available. Heavy Transport & Industry (Blue H2 + CCS): For sectors difficult to electrify directly, hydrogen produced via SMR with integrated Carbon Capture and Storage offers a viable transition path. Furthermore, combining biomass energy with CCS (BECCS) presents potential for net-negative emissions. 🔹 Market Reality & The R&D Edge Momentum is accelerating. We are seeing significant growth beyond stationary power into heavy-duty transport and large-scale infrastructure (with multi-gigawatt national targets announced globally). The R&D focus now—spearheaded by initiatives like the DOE's H2@Scale—is rightly targeting the remaining economic hurdles: reducing electrolyzer manufacturing costs and advancing durable, high-pressure storage solutions. The Outlook: H2 and FC technologies are no longer fringe elements. They are essential components for sector coupling and achieving deep decarbonization in a manageable, reliable energy system.
