Hydrogen Trains Uneconomic
Germany introduced hydrogen FCEV trains from 2018 in Frankfurt and Saxony areas. LNVG as now gone to tender for over 100 all battery electric as hydrogen too expensive and H2 trains termed “misery trains”.

Heat Pumps For Energy Savings
Heat pumps or air conditioners were invented in the early 1900’s and now are the most cost effective for heating and cooling. Replace gas heat systems with heat pumps reduces energy demand by 3 times.
Electric Ships
Coastal shipping with swap out electric container batteris have always been proposed to decarbonise shipping. Now the first 2 by Cosco are in production. 36 batteris, 24 Tonne CO2 per day less emissions
Queensland Pumped Hydro Proposals
Queensland has announced 2 large pumped hydro schemes costing over $30 billion and not due to come onliine on 2029 to 2035. Large projects have major financial risks, but QLD is determned to have large capacity long term storage.
Green Steel with Carbon Capture Unlikely
Green steel produced by direct reduction is likely to have metallurgical coal become a stranded asset, as cost reductions and increasing technology improvements to make green steel viable.
Fusion or Fiction
Fusion or fiction – can fusion actually provide essentially high quantities of low emission electricity. Or is another 30 years of research needed
Hydrogen for Home Heating
Sophisticated modelling shows hydrogen for home heating is a non starter except in a few use cases and heatpumps and batteries provide a more effective solution to home energy use.
IEA Forecasts Wrong by 7 Times
IEA have consistently under forecast the increase in solar panels (PV) globally by 7,000 times. in 2009, they forecast just 30GW of solar. In 2023 there will be over 440 GW installed. How do they get is so wrong?
Arctic Ice Cover Gone in 20 Years
A June 2023 article concludes sea ice will be sbsent in September as early as a decade, contradicting IPPC 6 conclusion it would not be until mid century. Lack of sea ice has major implications for climate change and weather
Food Disruption Impacts
The food revolution by precision fermentation will be the most profound of the 4 disruptions occuring. By 2030 the dairy industry will be bankrupt. By 2035 land used for beef and dairy farming will be not used.
Low Investment in Renewables By Oil Companies
Oil companies talk about changing to renewable energy but their investment in new energy is low to zero. Their claims should be dismissed as greenwashing.
Chinese Cars are Coming to UK
At the Fully Charged show in UK, the Chinese cars are coming. BYD, Geely, Great Wall, and SAIC all demonstrated new models addressing different market segments. Korean cars are already annouced.
Hydrogen Cult Madness
Is Hydrogen like a cult? Hydrogen cult madness? Proponents claim that H2 will solve the renewable energy transition challenges but the science evidence it wont.
Direct Air Capture – Unproven
DAC is at best unproven and more likely a strategy by major oil companies to delay meaningful reduction in green house gas emissions
Innovative Toroid Propeller Design
The innovative toroid propeller design for drones from MIT and for boats by Sharrow Marine show R&D continues to improve efficiency and will have a major impact on drones and shipping.
Ethanol Worse than Gasoline for Global Warming
Is ethanol worse than gasoline for global warming? Turns out it is worse! A recent publication showed that corn ethanol compared with petroleum products increased: So while it is clear ethanol mixtures for gasoline is bad policy, ethanol continues to be used in transportation due to the large
Gravity Batteries With Heavy Blocks
Gravity batteries using heavy blocks has moved from pilot phase to the first 2 demonstration plans in China (100MWh) and in USA. Watch their progress.
Grid Batteries Rapid Increase
The latest figures from Tesla show a rapid increase in the amount of grid storage deployed globally in the first quarter of 2023. Over 160GWh backlog in Tesla orders and over 300GWh projects announced for all batteries
Sustainable Aviation Fuels Unrealistic
SAF or Sustainable Aircraft fuels are unrealistic. Used cooking oils are as expensive. Agriculture is challenges. Synthetic fuel is expensive. What are some of the options
Carbon Capture and Storage Fail
Carbon Capture and storage is a strategy for reducing carbon emissions but the evidence is that it is a scam for fossil fuel companies to use government subsidies while at the same time increasing carbon emissions. Even worse, taxpayers will be responsible for end of life projects.
