There is a danger that the U.S. Inflation Reduction Act (IRA) subsidies for hydrogen production (defined in provision 45V) may create perverse incentives that do not reduce emissions and may increase them. James Sallee at the Energy Institute at Haas explains why. The goal is to make “green” hydrogen powered by newly built clean energy. But what if the generously subsidised hydrogen is made from clean energy (new or not) that should be powering … [Read more...]
Iron and Steel: how can Hydrogen and Direct Electrification replace fossil-based production?
Karan Kochhar, Luis Janeiro and Francisco Boshell at IRENA look at the decarbonisation of iron and steel. They account for about 7% of global energy–related carbon emissions. The authors explain what’s needed for green hydrogen and direct green electrification to take over from traditional fossil-based production. Many projects are in the pipeline, and the authors reference case studies like H2 Green Steel, SIDERWIN and Boston Metal. Though that … [Read more...]
Ammonia from water microdroplets: lab demonstrates cheap, low-tech production
Very early stage research has discovered a new way of making ammonia cheaply, on a small scale (or large, if you want!), and with no harmful emissions, explains Adam Hadhazy writing for Stanford University. The process uses a cocktail of water, nitrogen gas, and a solid catalyst sprayed through a simple, low-tech instrument to make the ammonia. In contrast, the existing industry-standard Haber-Bosch process is energy intensive, large scale, and … [Read more...]
EU’s 40% domestic Cleantech ambition: same target for Wind (easy) and Solar (hard) doesn’t make sense
The proposed Net Zero Industry Act includes a target for the EU to manufacture domestically at least 40% of its cleantech deployment needs by 2030. That includes the key technologies of solar PV panels, wind turbines (onshore and offshore), EV batteries, heat pumps and hydrogen electrolysers. But it doesn’t make sense to have the same 40% target for all, explain Giovanni Sgaravatti, Simone Tagliapietra and Cecilia Trasi at Bruegel. The main … [Read more...]
IEA report: global manufacturing capacity is expanding rapidly for solar, wind, batteries, electrolysers, heat pumps
The IEA summarises its special briefing, “The State of Clean Technology Manufacturing.” It’s a global update on recent progress in key regions, focussing on five technologies – solar PV, wind, batteries, electrolysers and heat pumps – critical to the energy transition. It should be read to keep decision makers informed of investment trends and the impact of industrial strategies. Overall, manufacturing capacity for these technologies is expanding … [Read more...]
Financing Renewable Hydrogen globally: ramp up to 2030 only needs $150bn/year
Dolf Gielen, Priyank Lathwal and Silvia Carolina Lopez Rocha at the World Bank present a thorough review of the pathway to financing global clean renewable hydrogen over the coming decades. The wind and solar that powers production will continue to get cheaper, and so will electrolyser costs as they scale up. Nevertheless, the total financing will still be considerable. World Bank analysis shows around $30tn between now and 2050 will be needed … [Read more...]
Making Hydrogen direct from seawater using double-membrane electrolysis
Can hydrogen be produced from seawater? The standard method requires water to be purified, which is expensive to do and adds complexity to the device. David Krause at the SLAC National Accelerator Laboratory, Stanford University describes new research there that uses electrolysis and a double membrane directly on the seawater to separate out the chloride and isolate the hydrogen and hydroxides. The system operates without generating toxic … [Read more...]
Should U.S. DOE risk funding methane-based Hydrogen production when CCS is still not proven?
The U.S. Department of Energy (DOE) is allocating $8bn for building regional clean hydrogen hubs. Decisions on who to fund are being made now and will be completed by the end of this year. Any methane-based hydrogen project that achieves a 95% carbon capture rate will be sufficiently “clean” to qualify for the federal funding. But, as Suzanne Mattei, David Schlissel and Dennis Wamsted at IEEFA explain, the few “at scale” CCS projects now running … [Read more...]
Hydrogen’s innovation pipeline: signals strong ahead of World Hydrogen Summit in Rotterdam, May 9-11, 2023
The IEA and the European Patents Office have, for the first time, reported on patents filed worldwide to get a measure of the innovations we’re seeing in the hydrogen sector, summarised here by Ian Shine. Overall, Europe and Japan are leading. Although the U.S. is a close third, with 20% of the total, their filings have declined compared to the previous decade. The fastest growth is in China (15.2%) and South Korea (12.2%). There has been a … [Read more...]
Blending Hydrogen into the gas network: the challenges of pipeline fractures, faster flow rate + more
An important part of the strategy of bringing hydrogen into the mainstream of the global energy sector is inserting it into the existing gas infrastructure. That will be done by “simply” blending it with the natural gas. But there are well known challenges and uncertainties, which have been interrogated in a report from NREL and partner institutions. Hydrogen, being the smallest element, can easily permeate solid metals and render pipeline steel … [Read more...]
Green Hydrogen’s 6,000-fold scale-up by 2050 must far exceed Wind and Solar’s. Is it possible?
To scale “green” hydrogen to make its contribution to limiting warming to 1.5C, electrolyser capacity needs to grow 6,000-fold by 2050 from today’s levels of 600MW, according to the IEA’s Net-Zero emissions by 2050 scenario. Adrian Odenweller and Falko Ueckerdt at the Potsdam Institute for Climate Impact Research, writing for Carbon Brief, summarise their study that concludes even if electrolyser capacity grows as quickly as wind and solar, it is … [Read more...]
Make Hydrogen in developing nations: share prosperity while meeting our climate goals
The new hydrogen economy will not just be global, it must be used as a major economic development opportunity for low income nations and promoting shared prosperity, explain Dolf Gielen, Silvia Carolina Lopez Rocha and Priyank Lathwal at the World Bank. They carefully lay out the obstacles and pathways for making hydrogen in developing countries. It’s very capital intensive, but such projects – think of existing fossil fuels, mining, etc. – have … [Read more...]
Making Hydrogen will consume 2% of total global renewable capacity growth by 2027
25 countries plus the EU have announced big ambitions for renewable hydrogen production. But how much renewable energy will be needed to make the H2 over the next five years? Nations are not keen to expend new clean energy generation on (expensive today) hydrogen production when their grids are still not emissions-free. According to the IEA, for 2022-2027, their main case forecasts around 50GW of renewable capacity will be dedicated to hydrogen … [Read more...]
EU Energy Outlook to 2060: how will power prices and revenues develop for wind, solar, gas, hydrogen + more
Alex Schmitt and Huangluolun Zhou at Energy Brainpool present a summary of their “EU Energy Outlook 2060”. Its scenarios map out how the European (EU 27, UK, Switzerland and Norway) energy system will change dramatically in the coming decades. Current geopolitical tensions are added to climate mitigation and an outdated power plant fleet as the main drivers of change at the EU and national levels. The in-depth modelling is trying to answer the … [Read more...]
Investing in Hydrogen: is there a “first mover advantage”?
Is there a “first mover advantage” – or not - for an investor in the new hydrogen economy? Michiel Korthals Altes offers a series of “tests” of investment decisions based on the following criteria: economics, climate efficiency, system optimum, price stability, regulation, technology, now and in the future. He concludes that until the sector reaches maturity, conversion inefficiencies make the production of hydrogen a poor choice for most … [Read more...]
