How would you use a nuclear-wind hybrid plant and maximise its potential? When intermittent windâs output falls, nuclear can step in to feed the grid. When itâs not doing that it can use its power to run the production of a wide range of commodities: from biofuels, hydrogen, pumped hydro to wastewater purification, desalination, chemical manufacturing and more â including straightforward thermal power for industry. In collaboration with NREL, the … [Read more...]
The top Clean Energy developments of 2020
The world is still a long way off the pathway to meeting our emissions goals. But 2020 saw a number of major steps in the right direction. Laurie Stone at RMI presents a list of what has been achieved and which trends and new policy commitments are pointing us towards a much needed faster transition. They include coalâs decline, wind and solarâs growing competitiveness (even compared to gas), the promise of green hydrogen, bans on gas/petrol … [Read more...]
HYBRIT project: Sweden goes for zero-carbon steel
Europeâs largest iron ore producer, LKAB of Sweden, plans to invest almost âŹ40bn over the next two decades in emissions-free steel production. LKAB, along with Vattenfall and SSAB, are behind the HYBRIT project which intends to grow, fossil-free, Swedenâs steel industry. They will use hydrogen instead of coal as the âreducing agentâ to remove the oxygen from the iron ore. Thomas Koch Blank at RMI runs through their strategy and the implications … [Read more...]
What effect will blending Hydrogen into the Natural Gas network have?
What are the technical barriers to blending hydrogen into the natural gas network? How well will the pipelines cope? How will the blend affect equipment and appliances? What are the costs and environmental impacts? The answers to these key questions are being sought by a collaboration of laboratories, industry and academia led by NREL, called HyBlend. The long-term impact of hydrogen on materials and equipment is still not understood. The effect … [Read more...]
How can Europe help build Chinaâs Hydrogen economy?
On 18th November Energy Post, in partnership with the EU-China Energy Cooperation Platform, hosted a series of online workshops under the theme âChina: Carbon Neutral by 2060â. The purpose was to understand the Chinese landscape and uncover opportunities for Europe. Here, the moderator for our âHydrogenâ panel, Gökçe Mete, summarises the workshop which included an expert panel discussion and questions from the audience. Taking part were Tudor … [Read more...]
The renewable electricity market in Ukraine: answers to the key questions
Tetiana Mylenka at Hillmont Partners law firm (Kyiv, London) answers key questions about the prospects for renewable energy in Ukraine. Is there any hope that the renewable energy sector in Ukraine is coming out of its crisis? As of today, it is too early to say that the renewable energy sector in Ukraine is coming out of its crisis. The adoption of the long-awaited Law No. 810-IX should resolve the situation and partially … [Read more...]
Biofuels vs Hydrogen: which can fuel aviation, shipping, trucks?
The positive signals coming from EV sales and charge points contrast with the lack of progress in finding alternative fuels for aviation, shipping and trucks. Cornelius Claeys runs through the prospects for biofuels and hydrogen to power long-haul transport. Biofuels are already used as a substitute for fossil fuels, and EV uptake will usefully free them for fuelling heavy transport. But as decarbonisation ambitions rise the pressure on scarce … [Read more...]
Which sectors need Hydrogen, which donât: Transport, Heating, Electricity, Storage, Industry?
Which sectors are most suited to hydrogen, and which are not? For the answer, six academics from the UK and the Netherlands - Tom Baxter, Ernst Worrell, Hu Li, Petra de Jongh, Stephen Carr, and Valeska Ting â use their areas of expertise to neatly summarise hydrogenâs pros and cons in Road and Rail, Aviation, Heating, Electricity and Energy Storage, and Heavy Industry. Their general message seems clear: hydrogen is still very expensive, so it can … [Read more...]
Green or Blue Hydrogen: cost analysis uncovers which is best for the Hydrogen Economy
Blue hydrogen is created from fossil sources, where the carbon emissions are captured and stored. Green hydrogen is made from non-fossil sources and favoured by policy makers who are wary of keeping the fossil economy going, even with CCS. As more regions commit to hydrogen, finding the right cost-optimal mix is crucial to its success. Schalk Cloete summarises his paper that models the whole system based on Germany. Integrating hydrogen will … [Read more...]
How will China build its Hydrogen economy?
What are Chinaâs hydrogen prospects? Thatâs 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...]
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 âInnovation Weekâ 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...]
No more âoffsettingâ: Google commits to 24/7 locally sourced carbon-free electricity by 2030
By âoffsettingâ fossil electricity consumed at one data centre through buying green power from somewhere else, Google has been 100% renewable since 2017. But offsetting always has its flaws. In this case, 40% of Googleâs actual power still comes from fossil fuels. Googleâs new plan, to be 100% green 24/7 straight off the local grid, is designed to solve that. It will also send market signals to increase clean capacity locally, not just where you … [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. Thatâs 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 â … [Read more...]
Will Saudi Arabia build the worldâs largest green hydrogen and ammonia plant?
The Gulf is already a major producer and consumer of hydrogen, mainly for fertilisers and specialty chemicals. Like most hydrogen produced globally, it is the âgreyâ kind made from hydrocarbons. But the regionâs low renewable power costs and abundance of land give it the key components for the industrial scale production of green hydrogen. So in July, the Saudi model city of Neom (Neom means ânew futureâ) and ACWA Power signed a joint venture … [Read more...]
