EV's vs Hydrogen Cars - Has Japan lost the plot?
Japanese automotive leaders still seem to have their heads in the sand when it comes to the future of the auto industry.While Tesla and Chinese car makers like BYD have spent much of the last two decades perfecting electric vehicle manufacturing, Japan has bet the house on its hydrogen strategy and is now paying the price. Japanese automotive exports have plunged 21% since 2019 while China’s have almost tripled. So, the reluctance of Japan’s automotive executives to recognise the limitations of hydrogen powered vehicles may have catastrophic implications for Japan’s economy.https://thedriven.io/2023/05/23/hydrogen-and-cow-manure-japanese-auto-leaders-still-cant-see-the-electric-future/

Big increase in EV's - how will they be charged?
The Electric Vehicle Council forecasts a million EV's in Australia by 2030, but it could be up to 1.7 million electric vehicles. This will require a lot of new charging by networks and much greater household electricity usage. In such an environment, 'managed electric vehicle (EV) charging' could save energy networks and energy generation owners millions, but only if  drivers of the future hand over control of their refuelling electricity use.Managed charging is a concept that gives third parties access to smart chargers in order to adjust power levels up or down - watch this space:https://reneweconomy.com.au/jemena-sees-big-rewards-for-vehicle-to-grid-services-big-risks-to-unmanaged-ev-charging/

All-electric homes save money, emissions & health!
 Electric appliances are cheaper to run than equivalent gas. Also, If every Australian gas household went all-electric today, we would “save”  30 million tonnes of carbon dioxide emissions over the next 10 years.And, analysis from a team at Stanford University found that a cooktop burner on high or gas oven set to 180 °Celsius, can raise the levels of house-bound benzene (linked to blood cancer) to levels more dangerous than passive smoking.So, we should all be electrifying and the government should subsidise low-interest bank loans for domestic electrification - watch this space:https://reneweconomy.com.au/all-electric-homes-save-money-and-emissions-new-gas-connections-should-be-banned/

Renewables need a new type of Electricity Grid
Described as the “biggest change to the power system in history”, we are seeing a move to High Voltage Direct Current (HVDC) transmission grids around the world. These grids are overtaking alternating current/AC systems whose magnetic fields generate substantial losses in the process of transmission.And to facilitate the switching from AC to DC and back (given most of our household systems are AC) we now have the insulated gate bipolar transistor or IGBT.Maybe sounds technical, but with these two technologies, we will be able to better manage our grids for renewable energy.A thoroughly interesting development: https://www.economist.com/technology-quarterly/2023/04/05/electric-grids-fed-by-renewables-n

Climate Entrepreneur meets Climate Activist
Tim Washington is CEO and co-founder of JET Charge, Australia’s largest EV charging technology business. Also co-founder of Chargefox, now the country’s largest EV charging network. One of Australia's growing generation of climate entrepreneurs.Anna Rose founded the Australian Youth Climate Coalition in 2005 and is among Australia's leading climate activists. Named in Australian Financial Review/Westpac’s 100 Women of Influence in 2019, Anna is a Director of Farmers for Climate Action and CEO of Environmental Leadership Australia. They are chalk & cheese amidst Australia's push to net zero and in a webinar together on Tuesday 6th June:www.climateandpeace.com.au

What fuel for ships - to decarbonise and achieve Net Zero?
A wide range of fuels are in the mix for heavy maritime use, through to 2050. So the Global Centre for Maritime Decarbonisation, the Global Maritime Forum, and the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping recently conducted a survey. Many respondents expect their fleets to run on multiple types of fuel well into the future. Options include Amonia, Hydrogen, Methane, Methanol, Bio-deisel as well as Fuel Oil.This suggests that shipping’s route to decarbonization could be complex and the industry is in a period of experimentation and exploration to understand the implications of adopting such fuels: https://www.mckinsey.com/ind
