Are firms in the switchgear industry - power utilities, industrial sites, and related service and infrastructure sectors - happy to switch from using the gas SF6 and use alternatives that are less harmful to the climate? This is the question Marie-Charlotte Guetlein and Carine Sebi at the Grenoble École de Management asked over 400 switchgear customers to find out what’s needed to make the change. SF6 has 23,500 times the impact of CO2 and an … [Read more...]
Decarbonising end-use sectors: buildings, transport, industry. Which strategies are best?
The rapid pace of change in the energy sector is a positive sign for the transition. But the disruption it causes creates another big problem. It makes it harder to predict what will happen next. That makes strategies and pathways harder to design, and increases the risk of stranded assets. To try to come to grips with that future, Sean Ratka, Paul Durrant and Francisco Boshell summarise the findings of IRENA's 4-day “Innovation Week” held last … [Read more...]
Net Zero by 2050 technically and economically achievable, says Energy Transitions Commission report
Making Mission Possible, the latest report by the Energy Transitions Commission, describes a net-zero world by mid-century as technically and economically possible. The solutions are already available or close to being brought to market. What is still missing is the will to embrace, rapidly and at scale, the inevitable disruption that will ultimately deliver net-zero emissions, lower air pollution, cheaper energy bills, create new jobs and raise … [Read more...]
Hydrogen, CCS, and more: without new clean energy technologies we cannot hit our 2050 emissions targets
The flagship 400-page report, Energy Technology Perspectives 2020, is another salvo from the IEA to concentrate the minds of the world on new technologies and their roll out. That’s because transforming electrification and the power sector alone, where most of the progress is happening, will only get us one-third of the way to net-zero emissions by 2050. The IEA has analysed over 800 new technology options. The most important categories – … [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...]
New U.S. climate bill is unprecedented in “ambition, concrete details, and urgency”
Mark Silberg, Alisa Petersen and Ben Holland at RMI pick out six highlights from a new U.S. climate bill and accompanying report that they describe as unprecedented in “ambition, concrete details, and urgency”. The Democrat-sponsored “Moving Forward Act” passed the House at the start of July and now goes to the Senate. Though regional commitments already get the U.S. halfway to meeting the 1.5°C goal, federal action is needed for the rest. … [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...]
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...]
Re-shaping the EU ETS as a safety net, not a driver
The EU ETS (Emissions Trading System) has struggled to cope with the current economic crisis which has caused a drop in the European carbon price, while the expected drastic drop in 2020 emissions will only add to the existing surplus of allowances. This highlights how necessary it is to reform the mechanism for managing this surplus or even to implement a carbon floor price, explain Charlotte Vailles at I4CE and Nicolas Berghmans at IDDRI. They … [Read more...]
An EU Hydrogen strategy: from industry feedstock to energy vector
The bravest recovery strategies will invest robustly in new yet-to-take-off clean energy technologies. If you are going to have to spend hundreds of billions to revive your economy isn’t it better to replace the old with the new rather than prop up what you’ll have to abandon soon anyway? In anticipation of that happening, new technologies are lining up. Here, Cédric Philibert at the IFRI Centre for Energy & Climate summarises their detailed … [Read more...]
IRENA’s Global Renewables Outlook and how Europe can lead the way
If the coronavirus slump has knocked everything off track IRENA’s first ever Global Renewables Outlook is a timely reminder of what that track should look like. It can help policymakers design stimuli packages that will get us back onto it, and even accelerate the transition. IRENA’s Gayathri Prakash, Nicholas Wagner and Ricardo Gorini run through the comprehensive report’s main recommendations. Annual investment, shares and GW targets to 2030 … [Read more...]
Green Ammonia can replace fossil fuel storage at scale
What’s the best way to store energy, from industry scale to electric vehicles, replacing the widespread use of fossil fuels? Pure hydrogen is an energy dense alternative, but the gas takes up a lot of space. Liquid ammonia doesn’t, yet it contains the hydrogen and therefore the energy. Ian Wilkinson at Siemens explains the advantages of using ammonia, NH3. Already the world produces 180m tonnes a year, worth €80bn. It’s mainly for agricultural … [Read more...]
Biogas and Biomethane’s untapped potential across the world
The IEA’s World Energy Outlooks have no doubt that electrification alone cannot meet our climate goals. That’s why natural gas continues to play a major role. But biogas and biomethane have the potential to replace 20% of that gas, says the IEA’s special report “Outlook for biogas and biomethane: Prospects for organic growth”. At present only a fraction of that is being utilised. Here the IEA summarises their comprehensive report. Costs are the … [Read more...]
Germany’s drive to decarbonise its prized heavy industry: an overview
Sören Amelang at Clean Energy Wire runs through their collection of factsheets, analyses, reports and interviews that have tracked German industry’s attempts to grapple with decarbonisation. The very high energy intensity required by industries like steel, chemicals and cement makes a simple switch to clean electricity – short of a total redesign of processes – impossible. But Germany wants to maintain, even extend, its world leadership in … [Read more...]
