Europe’s hydrogen ambitions need a reality check. The EU’s goal to produce and import 20m tonnes of clean hydrogen by 2030 is now widely seen as completely unrealistic, says William Todts at T&E. The business case is not good enough because of the high costs that aren’t coming down as hoped. It’s why only 4% of hydrogen projects get financed. Far better to focus on no regrets, low infrastructure hydrogen applications for ammonia-fertiliser, … [Read more...]
Annual Energy Efficiency improvements must double to meet climate targets. We know how to do it
Global energy intensity – a measure of how efficiently the global economy uses energy – improved by just over 2% in 2022. That needs to double to 4% annually to 2030 to meet global efficiency targets, explains Brian Motherway at the IEA. If achieved, by 2030 one unit of energy used will generate 40% more economic output than today. That’s huge, and shows why few other policy areas offer such widespread benefits. More than half of the 150 … [Read more...]
Green Methanol: an alternative fuel for heavy vehicles and shipping?
It’s very early days but pilot projects for green methanol are underway, explains Gabi Thesing writing for WEF. It’s a low-carbon fuel that can be produced from renewable sources such as biomass or using carbon capture. Compared to traditional fossil fuels it can reduce CO2 emissions by 60-95%, nitrogen oxide by 60-80%, and almost completely eliminate sulphur oxide and particulate matter emissions. Green methanol can be blended with traditional … [Read more...]
IRENA’s Innovation Week 2023: Renewable solutions to decarbonise end-use sectors
At the end of September IRENA held a four-day event “Innovation Week 2023: Renewable solutions to decarbonise end-use sectors” in Bonn, Germany. A wide range of speakers discussed tangible solutions to decarbonise energy intensive sectors such as transportation, buildings and industry, informed by first-hand project experiences and supported by insights from IRENA’s in-depth analyses. Topics included direct and indirect electrification, green … [Read more...]
Event summary: “Bioenergy after REDIII – sustainable, climate neutral fuels for industry, transport and negative emissions”
Sara Stefanini provides a written summary of our panel discussion held on Wednesday 4th October 2023. It’s a full summary of the 75 minute discussion, and begins conveniently with a summary of the highlights. Under the recently revised Renewable Energy Directive (REDIII) bioenergy can be counted towards the renewable energy targets – provided that it meets strict sustainability criteria. Bioenergy already accounts for 60% of the EU’s renewable … [Read more...]
Formula 1’s energy efficiency innovations for road transport are being wasted
Formula 1 racing is infamously emissions intensive. But the pressure to win is a pressure to innovate and raise energy efficiency, supported by an extravagant budget. Maximilian Auffhammer at the Energy Institute at Haas looks at what has been achieved over decades, and what has – and has sadly not – been translated onto our roads. The earliest cars had 4.5L engines that produced 400 horsepower, refuelled during the race. Today’s cars have 1.6L … [Read more...]
Could big U.S. subsidies for Hydrogen create perverse incentives, raise emissions?
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...]
Concawe Symposium tackles climate and pollution as RED commits fuel companies to 29% renewable content from 2030
With the adoption of REDIII last week we are set for a dramatic increase in the “renewable” element of liquid fuels. It means that in just 10 years, the renewable element will have tripled, rising from 10% in 2020 to 29% from 2030 onwards. In the EU, Concawe (a division of the European fuel manufacturing industry) develops scientific research and technical studies on the fuel industry’s products and operations, and their impact. Concawe is … [Read more...]
Affordable €25k EVs by 2025: Europe’s carmakers can do it. Instead they’re making more profitable SUVs
T&E present a summary of their study which shows that European carmakers can produce affordable EVs (40 kWh LFP battery, 250-300 km range) priced at €25k by 2025 with a reasonable 4% profit margin. Priced for the mass market, this would add a million extra EV sales annually, accelerate the removal of combustion engines, and counter China’s dominance of the EV market. The obstacle is the insistence by Europe’s leading manufacturers - BMW, … [Read more...]
U.S. Inflation Reduction Act: one year on, a summary of impressive progress in the energy transition
The U.S. Inflation Reduction Act has been described as unprecedented in its ambition for the nation’s energy transition. One year on from the passing of the bill in August 2022, Hannah Perkins and Adam Aston at RMI describe the progress on implementation as unprecedented too. The authors break their review down into categories: clean tech manufacturing, electrifying transport, greening buildings, decarbonising electricity, transforming industry, … [Read more...]
Germany plans for Carbon Capture in Industry: emissions, potentials, costs
In the first article of this series, Simon Göss and Hendrik Schuldt at carboneer gave the background to Germany’s new drive for carbon capture, and summarised the industrial sectors that will be its focus. Here, the authors analyse the emission profiles of German industries (in particular: steel, cement, lime, chemicals, waste incineration) and the associated CCS potentials and costs. The first thing to note is that it’s the process emissions … [Read more...]
The final hurdle for 100% Sustainable Aviation Fuel? Turning Lignin biomass into the “aromatic” component
Making 100% sustainable aviation fuel seems a long way away. Aircraft need energy-dense power, as delivered by fossil fuels, and sustainable alternatives are being developed. But a big challenge is that 10% - 25% of the fuel must be “aromatic” which neither thickens nor freezes at cold altitudes. Also, aromatics get absorbed by the plastic seals, make them swell, and ensure those seals between various components in the aircraft’s fuel system are … [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...]
Circular Battery Economy: what policies and processes can accelerate recycling and reuse?
As battery production scales up so do the risks of the long global supply chain failing, or causing more emissions, damaging the environment, and breaching human rights. A circular battery economy should greatly reduce those risks. Yet the U.S. has no federal recycling mandates or requirements for lithium-ion batteries, and state policies are inconsistent. Marie McNamara at RMI maps out the five critical issues that must be dealt with. Before … [Read more...]
“Battery Passports”: ensuring environmental sustainability, decarbonisation and mining labour rights
With battery production taking off, concerns are focussed on environmental sustainability, carbon footprint and labour rights where the raw materials are mined. Benedikt Sobotka, Co-Chair at the Global Battery Alliance and Robin Zeng, CEO at Chinese manufacturer Contemporary Amperex Technology, writing for WEF, describe the concept of the digital “battery passport” where compliance with the rules is certified and monitored throughout the life … [Read more...]
