President Biden's Leaders Summit on Climate last month helped focus minds on making firm commitments to reducing global emissions. As we all know, targets are one thing, credible and realistic solutions are another. To understand the challenge better, Dolf Gielen, Ricardo Gorini and Gayathri Prakash at IRENA break down into themes those areas that need much more effort and, if dealt with successfully, can get us to net zero by 2050: structural … [Read more...]
Industrial Clusters: the logic of co-location now has a new driver, net-zero emissions
Industrial clusters locate plants and factories in one area to share resources, problems and solutions. They already have a long history of collaboration. But the logic of co-location now has a new driver: net-zero emissions. The sectors can range from heavy industry (e.g. steel and cement) to light (food, paper, etc.) The challenge is to make the most of new clean technologies and processes, and at the same time maintain or increase … [Read more...]
Carbon Border Adjustments: can the EU create a mechanism that is fair?
The proposed EU carbon border adjustment mechanism (CBAM) is meant to control imports of high-carbon goods from places that are not bound by Europe’s rising de-carbonisation rules. The obvious targets are commodities like steel, aluminium and cement. But it could be extended to all EU imports, including agricultural products. Michel Colombier at IDDRI warns that the EU is in danger of not listening nearly enough to its trading partners. He … [Read more...]
Decarbonising Industry is key to China’s net-zero strategy
China has committed to a CO2 emissions peak before 2030 and carbon neutrality before 2060. It’s 14th 5-year plan will be released in March, followed by sector-oriented plans. For the first time it will include a dedicated plan addressing climate change. Dolf Gielen, Yong Chen and Paul Durrant at IRENA start by laying out China’s energy mix for scrutiny, then dive into its industrial sector which accounts for 60% of gross final energy use. Success … [Read more...]
Bioenergy is the undervalued pillar of the clean energy transition
Bioenergy is already the world’s largest source of renewable energy, responsible for 70% of the supply (and around 10% of total primary energy). Burning organic matter goes back to the invention of fire and is still commonplace around the globe. Yet it gets hardly any of the attention and policy support that’s given to other clean energy technologies like solar, wind and now hydrogen. Bioenergy can and should play an even greater role, explain … [Read more...]
How will China build its Hydrogen economy?
What are China’s hydrogen prospects? That’s the question Kevin Tu at the IFRI Center for Energy & Climate attempts to answer in a report that he summarises here. He points at the growing number of policies that show China is taking hydrogen very seriously. China wants to expand production as well as build up end uses in transport, steel and cement manufacturing, and storage. The main drivers are the Covid pandemic, energy security, the … [Read more...]
Little progress decarbonising Industry. Renewables can be the answer
The decarbonisation of heavy industry is making little progress. There are two main reasons. Firstly, there are no easy technology wins. Efficiency and carbon capture have been the favoured options. But efficiency gains have their limits, and carbon capture is still proving very expensive. Secondly, governments don’t want their home industries to lose competitiveness incurring costs reducing emissions. Dolf Gielen and Paul Durrant at IRENA say a … [Read more...]
IEA: Without accelerating clean energy innovations we cannot hit net zero by 2050
The impressive rise of renewables and energy efficiency, alone, will not be sufficient to meet the world’s 2050 emissions goal, says the IEA in its flagship Clean Energy Innovation report. New technologies, taken all the way through to widespread adoption by the market, must become an essential part of the net zero pathway. The stark warning is that existing policies to decarbonise shipping, trucks, aviation and heavy industry are not nearly … [Read more...]
“Green” chemical plants that ramp up and down with wind, solar
One solution to variable renewables is to create customers that have no problem with ramping up and down production along with the power. In fact, when the wind and solar is producing too much power for the grid it can be bought very cheaply, making intermittent customers very happy. Jim Conca describes a new design for a Chlor-Alkali Chemical Plant that can “idle” without critical components of the plant degrading – the main reason for a plant … [Read more...]
Tipping Points reached for Solar, Wind, Batteries, EVs. What of the other Clean Energy techs?
History shows a disruptive technology’s tipping point can be under 5% of market share, that’s all it takes. The number of horses in use peaked in the U.S. once car ownership reached 3%. Gas lighting in the UK peaked with electric lighting at just 2% of the market. Landline phones in the U.S. fell precipitously after mobiles captured 5% of the market. Ji Chen and Koben Calhoun at RMI argue the tipping point has already been passed for solar, wind, … [Read more...]
Allam Cycle carbon capture gas plants: 11% more efficient, all CO2 captured
Globally, carbon capture is making precious little progress. Is the Allam Cycle natural gas power plant an important step forward? David Yellen at the Atlantic Council Global Energy Center explains that, according to its designers, its energy conversion efficiency is 59%, 11% more than a standard combined-cycle gas turbine plant that’s carbon capture-equipped. It also captures 100% of the CO2, 10% more than the standard. NET Power plans to bring … [Read more...]
New EU Industrial Strategy focuses on emissions, but is it enough?
This month the European Commission released its new EU Industrial Strategy to set the direction of travel for the EU economy in the context of the European Green Deal. Energy-intensive industries - like steel, cement, aluminium, paper and chemicals - account for roughly 17% of EU emissions and have struggled to reduce them in recent years. But Johanna Lehne at E3G doubts the strategy is enough to meet the ambition of becoming the first … [Read more...]
Norway’s “Northern Lights” project: creating the CCS business model
Northern Lights, a carbon capture and storage (CCS) project backed by the Norwegian government, is drilling test wells in the North Sea to find suitable places to store CO2. Project partners include Shell and Total, and others are joining them. CO2 will be shipped to an onshore terminal from which it is piped to the subsea wells. Once established, the plan is for other European countries to send their CO2 too. The project will also create the … [Read more...]
Don’t wait for international agreements. Sector-wide action can accelerate the Transition
December’s COP25 in Madrid showed how difficult it is proving to get agreement between nations on how to ramp up the deep decarbonisation the world needs. David Victor at the University of California, San Diego, writing for Rocky Mountain Institute, accepts that international consensus is never going to be easy. Instead, he recommends that individual sectors take control of their destiny. His co-authored report “Accelerating The Low Carbon … [Read more...]
EXCLUSIVE INTERVIEW – GCCA’s Claude Lorea: “How can we provide the world with the concrete it needs in a sustainable way?”
Concrete is, after water, the most consumed resource on the planet and no other man-made material is more widely used. Without it, there are no buildings, bridges, dams or roads – no Sydney Opera House, no Hoover Dam or Golden Gate Bridge, no Pantheon in Rome. It is no surprise, then, that it has significant environmental impacts. More than 4bn tonnes of cement, the main ingredient of concrete, are produced every year leading to between 5 and 8% … [Read more...]
