EnergyScape: progressing towards a secure energy future

The New Zealand EnergyScape project will create a data framework which relates key parameters (e.g., cost, risk, greenhouse gas emissions) across the entire New Zealand energy network. Users will then have a tool to forecast the impacts of given policy measures, such as comparing the effects of an energy future dominated by carbon sequestration and biofuels, with a future dominated heavily by renewable electricity and electric cars.
EnergyScape is well underway.

When the Australian government needed an independent expert opinion on the health risks of air pollution from urban road tunnels, it chose a New Zealand scientific team.
Across the Tasman, huge urban motorway projects are underway involving extensive use of tunnels. Sydney’s Orbital Motorway now has 14 km of tunnels, and up to 20 km of tunnels are mooted for central Brisbane.

Get ready for the hydrogen economy

Biogas power made easy

Biogas power made easy. It took less than two hours to convert an off-the-shelf generator to run on biogas at Dexcel’s Scott Farm, near Hamilton in the Waikato. Equipment with a total load of 9–10 kW ran happily for over two hours on electricity from the generator. And, unlike petrol or diesel, there was almost no black soot or odour.

Cutting emissions: what will it take?

Cutting emissions: what will it take?
In early May, the Intergovernmental Panel on Climate Change (IPCC) released a ‘Summary for Policymakers’ of its latest report examining the options and costs of reducing greenhouse gas emissions.
Current policies and practices, it says, would see global greenhouse gas emissions continue to grow over the next few decades.

Charting the path to a hydrogen economy

Charting the path to a hydrogen economy
The CRL Energy-led project, Transitioning to a Hydrogen Economy, is part of the search for a long-term solution to New Zealand’s need for both energy security and environmental sustainability.
A hydrogen economy offers the prospect of ‘decarbonised’, very low emissions transport, greatly reduced dependence on imported fuels, high process efficiencies, and the development of clean, efficient small-scale distributed energy systems.
Mass market hydrogen cars are still some years away, but informed investment decisions need to be made well

Investigating bioenergy options

Investigating bioenergy options
Can bioenergy for heat, power, and transport fuel significantly enhance New Zealand’s energy options, assessed in terms of price, security of supply, and environmental outcomes?
As we outlined in the previous issue of Climate-Energy Solutions Update, bioenergy is the energy derived from the conversion of plant material to provide heat, power, or liquid fuels.
