Behaviour change is as an important part of our transition journey as the clean energy revolution. Kimberly Nicholas at Lund University summarises research that has gathered together nearly 800 peer-reviewed reports and case studies from across Europe that analyse ways of reducing car use. One main challenge is to quantify the benefits so policy-makers and citizens can make evidence-based decisions on how to re-imagine city mobility. Nicholas … [Read more...]
What’s best for Hydrogen transport: ammonia, liquid hydrogen, LOHC or pipelines?
The ability to transport hydrogen in bulk will mean clean energy can be taken where it’s needed, as easily as fossil fuels are today. But there is a cost involved in converting the hydrogen into something easy to transport (and un-converting it at the destination). Herib Blanco at IRENA summarises the findings of their paper that looks at those costs: a better understanding will enable us to choose the right pathways today fit for the next 30 … [Read more...]
Solar + Storage Hybrid plants are poised for explosive growth in the U.S.
At the beginning of 2021 the U.S. had 73 solar and 16 wind hybrid projects, amounting to 2.5GW of generation and 0.45GW of storage. By the end of 2021, over a third of the 675GW of solar in the grid connection queue were hybrids, and 19GW were wind hybrids. Only one in four typically get approved, built and connected. But that still points at a twenty-five-fold increase in hybrid generation. It’s why Joachim Seel, Ben Paulos and Will Gorman at … [Read more...]
Pathway for 100% Renewables in 24 U.S. states by 2035
We should not be surprised to see a growing number of 100% renewables roadmaps, with target dates in the 2030s, from nations as the transition gains pace. This study, “On the Road to 100 Percent Renewables” led by The Union of Concerned Scientists (UCS), details how the 24 states that make up the members of the U.S. Climate Alliance (USCA) can meet all of their electricity needs with renewable energy by 2035. Paula Garcia at UCS summarises the … [Read more...]
Piloting peer-to-peer electricity markets in China and the EU
Peer-to-peer (P2P) electricity trading is being promoted, to varying degrees, in both the EU and China. It allows individual citizens and businesses to produce and trade their own solar power (local, rooftop), while enabling the close-to-real-time balancing of supply and demand to maintain system stability. Helena Uhde at the ECECP gives an insight into the current status, implementation, regulations and policies in both regions. She cites two … [Read more...]
Europe must simultaneously replace Russia’s fossil exports and accelerate its clean energy deployment
The Ukraine crisis has had an immediate impact on Europe’s strategy for energy supply security. And this week’s sudden halting of gas supplies by Russia to Poland and Bulgaria only emphasises the urgency. Dolf Gielen, Ricardo Gorini, Luis Janeiro and Seán Collins at IRENA look at the best options, basing their findings on their latest “World Energy Transitions Outlook”, published in March, that lays out a routemap for the next eight years for … [Read more...]
Rotterdam’s World Hydrogen 2022 Summit & Exhibition: 3,000+ attendees, 120+ businesses, 9-11 May
The World Hydrogen 2022 Summit & Exhibition will open its doors to over 3,500 industry professionals on 9-11 May in Rotterdam where more than 120 leading hydrogen companies will be showcasing their technologies, applications and solutions at the city’s largest arena, the Rotterdam Ahoy. The anticipated meeting is the first large-scale hydrogen-focused event to take place following the pandemic in Rotterdam, a city recognised for its advances … [Read more...]
What’s best? Building Solar panels that last 30 years, or are short-lived easy-to-recycle and upgrade
The good news is that PV modules last so long – 30 years – that we don’t have to worry about recycling for a while. The bad news is that means we’re not thinking about the alternative pathway of deliberately building modules that last only a few years yet can be easily recycled and improved. Harrison Dreves at NREL describes the data-gathering and creation of a modelling tool that quantifies the flow of materials, energy, and carbon in the PV … [Read more...]
Wellbeing peaks at just 75GJ per capita: a reachable target for poorer nations to rise to (and rich ones to fall to)
Energy consumption is strongly linked to health and wellbeing, in particular life expectancy, infant mortality, happiness, food supply, access to basic sanitation services and access to electricity. But as Josie Garthwaite at Stanford University explains, new research is saying that those improvements cease above a certain number of gigajoules per person per year. Knowing that number will make understanding and setting targets much easier. For a … [Read more...]
How could Germany wind down Russian oil imports by the end of 2022
Berlin has said that, though difficult, it could become independent of Russian oil imports by the end of 2022, with a target of halving them by the middle of the year. Kerstine Appunn at Clean Energy Wire compiles information on the practical challenges for Germany’s oil infrastructure, refineries and security of supply. Germany is serviced by three pipeline systems for the west, the east and the south of the country. But they are not connected … [Read more...]
Post-war Ukraine needs energy independence, decarbonisation and EU cooperation
Energy independence is a choice for some countries. For Ukraine it is a life-or-death necessity, says Andriy Konechenkov, VP of the World Wind Energy Association and Chairman of the Ukrainian Wind Energy Association, in this op-ed. The Russian invasion has exposed the vulnerability of Ukraine’s current energy system. Many of its fossil-fuelled power plants are near the Russian border, exposing them to disruption by the invading neighbour. The … [Read more...]
Europe’s long-term energy security: do not become dependent on “green” Russia’s future LNG and Hydrogen exports
It’s not enough for Europe to cut Russian energy imports without a plan to make the change endure, says Leslie Palti-Guzman writing for the Atlantic Council Global Energy Center. Boycotts and divestments usually have expiry dates. What’s more, Russia will be proactive in driving its export capabilities to make them commercially attractive in the post-war world. Russia plans expanding LNG shipments from its Yamal Peninsular, as well as getting … [Read more...]
46% of Buildings “Embodied Carbon” can be slashed at little to no cost
Buildings and their construction account for around 40% of all carbon emissions today. Half those emissions come from the construction alone, so buildings successfully powered by clean energy won’t come close to fixing the whole problem. John Matson and Rebecca Esau at RMI describe how industry leaders are creating the tools to measure and gather data on the “embodied carbon” in building materials (concrete, rebar, glazing, insulation, other … [Read more...]
Q&A: How fast can renewables deliver on Germany’s new energy independence goals?
How quickly can Germany reduce its dependence on fossil fuels? Benjamin Wehrmann at Clean Energy Wire asks six practical questions that must be answered, then gathers the expert answers. What are the current expansion goals for wind, solar and other renewables? Following Russia’s invasion of Ukraine, will the new emergency plans bring an end to Russian imports as well as reach climate targets? Are renewable power companies ready to deliver a fast … [Read more...]
Aviation policy alert: non-CO2 emissions have up to four times the climate impact
There’s little point designing CO2 policies without knowing what other factors are heating up the atmosphere. So it is with aviation. The non-CO2 emissions (aromatics, NOx, SO2, H2O, particulate matter, etc.) from jet engines have up to four times the effect of CO2. You can see it in the contrail cirrus streaks trailing behind aircraft. Carlos LĂłpez de la Osa at Transport & Environment summarises their recent summit that brought together … [Read more...]
