Japan releases plan to achieve net zero carbon emissions by 2050

Recently Japan released its plan for reaching net zero carbon emissions by 2050. The government is to give tax incentives and other support for investment in green technologies and predicts that this will boost its economy. The plan is to include at least these developments:

 - To have all new cars to be electric, plug-in hybrid or hydrogen fuel cell driven by 2035 with a ban on the sale of fossil fuel driven cars. 

- To research into reducing the cost of batteries.

- To increase offshore wind power to 45 gigawatts by 2040.

- To bring renewable power to 60% by 2050.

- To be less reliant on nuclear power and have it more stable.

- To have thermal power plants with carbon capture technology related to carbon cycling and not storage underground. That is by using captured CO2 to produce synthetic fibres or to fortify concrete.

- To have nuclear and thermal power at a reduced 30-40% of the nation's electricity demand.

- To have all new buildings and houses built with zero emissions technology by 2030.

- To use green hydrogen and ammonia as fuels for gas turbine power generators and for fuel cells to power heavy vehicles and all sea-going vessels by 2050. (Japan has already launched its first hydrogen-carrying ship which is importing hydrogen from Australia.)

South Australia aims for 500% renewables by 2050 and for all new cars to be electric by 2035

 

(Source bbc.com)

The South Australian (SA) government aims for more than 500 per cent renewable energy by 2050 as it aims to become a clean energy exporter both nationally and internationally. Almost under the same breath, the government also announced that it aims to ensure that all new car sales will be electric by 2035 as it wants to be a leader in the uptake of electric vehicles in Australia.

SA already has its electricity grid at 60% renewables and plans to expand that to at least 500 per cent. The government has a Climate Change Action Plan which includes at least 68 proposed activities for more renewables, clean transport and more resilient urban and rural communities. The state has an abundance of solar, wind and other resources. The green hydrogen industry is well on its way in Australia and SA plans to become a major exporter of green hydrogen and other low emission products.

The state Liberal government has also released its plan for electric vehicles (EVs). Firstly it will electrify all government fleets, taxis and ride sharing vehicles by 2030. By 2030, they want electric cars to be mainstream and for all new cars sold to be electric by 2035. There will also be fuel efficiency and quality standards introduced which will help EV uptake but there is also a plan to put a road user tax on EVs which will be a disincentive but will help fund the changes.

A remote West Australian town to test a renewable hydrogen microgrid

Source: One Step off the Grid


A remote coastal town in Western Australia (WA) called Denham is now powered by four old wind turbines and a diesel generator. The community pays a high price for having the diesel trucked in and the turbines are at least 20 years old.

To generate most of their own power, the plan is to have a 704kW solar system, a 348kW hydrogen electrolyser, a compressor for hydrogen storage and a 100kW fuel cell to make electricity from the stored hydrogen when needed. There will be enough power for 100 homes but the new items will be connected to the existing system which will act as a backup. The hydrogen electrolyser, powered by solar energy, will split water to make green hydrogen. A Hydro Harvester could be used if water is scarce. 

The project is getting funding assistance from ARENA (Australian Renewable Energy Agency) which will use it as a test case for use in other remote Australian communities. "The potential for these communities to generate, store and use their own renewable energy could simultaneously reduce costs and reduce emissions without sacrificing the reliability of energy supply." said ARENA CEO Darren Miller.
