Across the world, industry is regarded as a hard-to-decarbonise sector, and an emissions priority. In China it’s responsible for over 65% of its energy consumption and 70% of carbon emissions. Ji Chen and Shuyi Li of the Rocky Mountain Institute (RMI) look at the highlights of China’s efforts, and reference them against the RMI’s Reinventing Fire: China analysis. Efficiency, electrification, CCUS, hydrogen and “recycle and reuse” all play an … [Read more...]
The Clean Hydrogen revolution: how, by whom, when?
Hydrogen rivals oil and gas for storage and hard-to-decarbonise sectors (industry, heavy and long distance transport). But it isn’t all carbon free. “Grey” hydrogen – the cheapest at €1.50/kilo - is made from gas. “Blue” hydrogen depends on the fortunes of carbon capture technology. “Green” hydrogen is CO2 free, but needs further cost reductions in the green electricity used in the electrolysis process. Noé van Hulst, at the Netherland’s Ministry … [Read more...]
50% Hydrogen for Europe: a manifesto
Electricity has well known limitations, mainly for bulk and long-range transport, industrial processes requiring high temperature heat, and the chemicals industry. To entirely replace fossil fuels we need hydrogen, say Frank Wouters and Prof. Dr. Ad van Wijk. It has an energy density comparable to hydrocarbons. There's more: Europe’s electric grid can’t cope with 100% electrification, yet hydrogen would use the existing gas pipe networks. The … [Read more...]
Hydrogen round-up: “fuel cells will replace diesel engines within 10 years”
As the focus moves from decarbonising the electricity sector to embrace transportation and heating, slowly but surely, hydrogen is starting to play a more important role. The gas has a number of advantages over electricity, including its flexibility and the fact that it can provide energy storage for long periods of time, unlike electricity. It can use the existing gas network if it is used for heating, and it is more appropriate than electricity … [Read more...]
New “Gas for Climate” scenarios: can green gas and hydrogen save gas pipelines?
Gas has a key role to play in decarbonising the energy sector. Until a comprehensive clean energy network can accommodate variable renewables using storage, baseload power will be needed. Natural gas is a lower carbon option than coal, so there is a strong case for it to be the first-choice bridging fuel towards a net-zero energy economy. However, exactly how much gas, what type of gas and how existing infrastructure can store energy in the form … [Read more...]
Renewable hydrogen “already cost competitive”, says new research
Jocelyn Timperley at Carbon Brief has interviewed the lead author, and the critics, of this new report titled “Economics of converting renewable power to hydrogen”. The research says renewable hydrogen is already proving competitive for niche, high-intensity users in Germany and Texas. Future technological improvements, combined with expected changes to subsidies and CCS requirements, can make it so for large-scale industrial users in the next 10 … [Read more...]
The compelling case for carbon capture and storage
By 2040 60% of primary energy will still come from fossil fuels, says the IEA. That means Carbon Capture and Storage (CCS) must be part of the technology mix to hold back climate change. Yet today there are only 18 CCS facilities in operation, with 25 in the pipeline. We’ll need at least 2,000 by 2040. Brad Page, CEO of the Global CCS Institute, lays out the reasons why we have no time to lose. The World Economic Forum’s meeting in Davos … [Read more...]
Hy-Society – flexible hydrogen’s winning formula
Open the papers and you'll see that hydrogen-based transport, mobility and infrastructure are securing serious investment. In the past, the high cost of fuelling infrastructure - and "stupid" concept of using electricity to make hydrogen to make electricity - have stalled the advancement of this ultra-versatile clean fuel and energy storage solution. However, thanks to the availability of surplus power from RES and hydrogen's remarkable … [Read more...]

Why decarbonising gas might be harder than you think
Decarbonising the European energy system by 2050 will require a fundamental shift for the way the gas industry operates, away from business-as-usual in network planning and market design. Achieving net-zero greenhouse gas emissions in Europe, in line with the Paris Agreement on Climate Change, leaves no room for fossil gas consumption where CO2 is not captured and stored. But turning the gas industry into a zero-carbon industry is no simple task. … [Read more...]
Hydrogen is heading up the European policy agenda
Hydrogen’s momentum is building, as European ministers consider approving a new ‘Hydrogen Initiative’ this week that aims to “maximise the great potential of sustainable hydrogen technology.” With funding from the EU’s Fuel Cells and Hydrogen Joint Undertaking, a consortium of industrial heavyweights in the H2FUTURE project is already ramping up production of hydrogen from renewable sources. But, as the International Renewable Energy Agency notes … [Read more...]
Beyond oil: options for clean fuel production
Several options exist for clean fuel production in the long-term future, writes Schalk Cloete in the third and last part of a series on the future of the internal combustion engine. Next-gen biofuels have the potential to approach current oil prices at a low environmental cost. Hydrogen can be produced economically from excess wind/solar power, nuclear heat or fossil fuels with CCS. Ammonia and hydrocarbon synfuels from clean hydrogen can be … [Read more...]

The growing potential of green hydrogen
The idea of a hydrogen-based economy has been around since the oil crises of the 1970s, but it has not materialised up to this point. Yet according to Jan Cihlar of Ecofys, a Navigant company, hydrogen could still become a key enabler of the low carbon transition, if it is produced with renewable electricity. The potential of further cost reductions make this a possibility in some applications in transport and industry. … [Read more...]
The lowdown on hydrogen – part 2: production
Electrolysis, powered by renewables, is often seen as the ideal way to produce hydrogen. But electrolysis is expensive and not always efficient, writes Roger Arnold. There are other ways that are more efficient and also climate friendly. This is part 2 of a two-part series on hydrogen written by independent energy expert Roger Arnold. Part 1 deals with the uses of hydrogen in transport. … [Read more...]
