How influential/significant is RE100? The Korean government appears to have adopted CFE as a target instead as it allows for nuclear and hydrogen power as well as renewables. They had a press conference today about CFE as well as RE100 where the Ministry of Industry seem to be trying to appease corporates by saying “you only need renewables to have powered the portion of products going to RE100 customers”. In 2021, Samsung Electronics disclosed that 43% of revenue is to RE100 customers and they were likely to lose to about 20% should they fail to meet the renewable energy requirement. As of 2024, more customers have joined RE100 and so potentially the revenue at risk is bigger. Focusing on “pragmatic” CFE is one thing… especially since there are only 20 corporates as members - all Korean. But ignoring RE100 is not going to help. While the number of companies that have signed up for the initiative remains at only 400 or so, it is getting larger and the last I checked, criteria for 2024 is getting even stricter. https://lnkd.in/gyKJrUHS

In 2022, the U.S. Energy Information Administration (EIA) projected a record-breaking power demand of 4,027 billion kWh. Natural gas and coal were set to account for about 37% and 22%, respectively, of this unprecedented demand for energy, followed closely by nuclear at 19%. The balance belonged to renewables. As the global supply of fossil fuels comes under increasing pressure from the evolved demand patterns of post-pandemic economics and a growing impetus for sustainability, renewable energy sources are in focus. However, the current renewable and alternate energy paradigm is not without its unique pitfalls. Take the case of Hydrogen! Read on: https://lnkd.in/gkDpGnGd #EngineeringTheChange

Using the properties of #co2 in power systems can support a climate-friendly energy transition. Affordable, clean power is essential to drive sustainable economic development. Renewables such as wind, solar, hydro, and tidal power will be integral to a low-carbon energy mix. However, baseload power and long duration energy storage will be required to supplement these non-programmable renewable power sources. CO2 can support that in several ways. The Allam-Fetvedt cycle enables thermal power generation from fossil fuels with zero CO2 emissions to air. It uses supercritical CO2 (sCO2) from oxyfuel combustion as the main working fluid in a semi-closed Brayton cycle. sCO2 is also at the heart of the indirect-fired supercritical CO2 recompression Brayton cycle which can be used with concentrated solar power, or on modern nuclear reactors. The STEP (Supercritical Transformational Electric Power) project is being executed by General Electric and the Gas Technology Institute (GTI) at the Southwest Research Institute (SwRI) site in San Antonio. It will operate a 10MWe power plant using a recompression closed Brayton cycle (RCBC) with sCO2 as the working fluid. This 10MWe plant will be the world’s largest indirect-fired sCO2 power cycle test facility, with operation and testing during at the end of 2024. Supercritical CO2-based power cycles have the potential for increased heat-to-electricity conversion efficiencies. As a power generation working fluid, sCO2 combines the best properties of both a liquid and a gas because it has a high density and low viscosity. A large amount of energy is lost when steam turns back into water in the Rankine cycle. The implication is that only one third of the energy in the steam can be converted into electricity. In comparison, the sCO2 Brayton cycle has a theoretical conversion efficiency of more than 50%. In addition to its use as a working fluid in power generation, CO2 can be used in a reversible power storage cycle to compliment non-programmable renewable power sources. The Italian startup Energy Dome uses gaseous and liquid CO2 in a closed cycle in their CO2 Battery™. The technology is a form of #ldes that avoids the use of batteries. The Energy Dome cycle expands vaporised liquid CO2 across a turbine to generate power during periods of peak demand. The expanded CO2 is stored in a large dome at atmospheric pressure. When there is abundant renewable power generation from solar PV sources during the peak daylight hours, CO2 gas is withdrawn from the dome. It is compressed and liquefied using excess power from the grid which may otherwise be curtailed. Liquid CO2 is stored in cryo-tanks, like those used in #industrialgases applications. Interested to know more about CO2 sourcing, supply chains and utilisation? Join us in Telfs in Austria on 19th and 20th Jan for the gasworld CO2 Summit. I will be presenting on the theme of CO2 utilisation for #efuels production. See you there?

By early 2025, renewable energy is poised to surpass coal, constituting over one-third of total electricity generation, as per the International Energy Agency. The agency's Electricity 2024 report indicates accelerated global power demand, with low-emission technologies meeting the rising consumption, signaling a swift energy transition. #renewableenergy #renewables #cleanenergy #unitedsolargroup

Renewable energy isn’t just a trend; it’s the solution to our rising global #energy demand. The latest report from the International Energy Agency (IEA) confirms what Sunnova Energy has been advocating for years—the world is turning to #cleanenergy to power its future with solar and wind on course to surpass coal as the world’s top source of energy in early 2024. This is a victory for the environment and a testament to the momentum behind renewable technology. Solar power is emerging as the frontrunner in this clean energy revolution, paving the way for a world less reliant on fossil fuels. During Q4 2023, Sunnova placed more than 34,000 customers into service, displaying the rising interest in #solar backed by quality guarantees. The entire energy industry needs to realize the immense potential solar offers to a more sustainable environment. More from World Economic Forum.

Last year, global energy production from renewable sources increased by 13% to a record level of 4,748 TWh. This growth was almost entirely driven by wind and solar energy. It accounted for 74% of all net additional electricity generated. Humanity also set a new record for consumption.

Electrification and hydrogen pathway future energy use Here is simple analysis that I hope is of some interest. Apologies to those that view the findings as obvious. The top left figure shows UK energy use leading up to covid. I’ve used the data to calculate what a future period might look like for an electrification, green and blue hydrogen pathway as the UK transitions to net zero. The following assumptions are made. As a result of energy efficiency measures, electricity and gas use drops by 20%. For the electrification pathway, 70% of gas is electrified with a cop of 2.0. 80% of transport is electrified with a BEV energy efficiency 2.5 times better than an ICE. That produces the top right figure. For the blue hydrogen route, hydrogen synthesis is 75% efficient. 80% of transport moves to hydrogen and a FCEV has the same efficiency as an ICE. The outcome is bottom left. For the green hydrogen route the efficiency of electrolysis is 75%. The same assumption for blue hydrogen in transport is made producing the bottom right figure. What is evident? Due to the efficiency improvements offered by electrification the seasonal variations are less and the peak energy usage has dropped by over 40% Electricity use doubles from pre-covid values. For blue and green hydrogen, total energy usage is only slightly less than historical business as usual values. Electricity requirements for green hydrogen are 25% higher than for the electrification scenario. Whilst this simple analysis brings out some key energy points. It does not address a beast from the east with no wind and little solar. Though, the analysis does show that electrification would need less dispatchable energy. Dispatchable energy requirements would be dependent upon nuclear base load and load shifting. Dispatchable energy would be a mix of: Unabated fossils Abated fossils Thermal storage Batteries - macro and micro Hydrogen Hydrogen derivatives Hydro Geothermal Tidal Wave Compressed gases Bio-fuels Interconnectors Also, I’m not what many accuse me of - blind-sided by energy efficiency. Pathways have to be determined from system wide, risked comparisons of - capex, opex, safety, environment, operability, schedule, technical maturity, NPV, NPC and IRR. That system wide comparison is lacking in my opinion.
