Green hydrogen costs projected to decrease by up to 60% by 2030
A new report from Hydrogen Council predicts that the cost of renewable hydrogen production will fall drastically by up to 60% over the coming decade due to the declining costs of renewable electricity generation and the scaling up of electrolyzer manufacturing. Thanks to its optimal renewable resources, Australia will be among the countries most favorably placed to contribute to the development of the hydrogen economy.
Switzerland increases net metering tariff for rooftop PV
Swiss renewable energy association VESE has reported an average 4% increase for owners of PV systems not exceeding 10 kW in size. However, the remuneration continues to vary widely between the 30 largest network operators in the country.
MIT researchers put slimmer silicon back on the table
With solar grade polysilicon prices having plummeted in recent years, cutting down on consumption of the material has not been a priority. But strategies exist and significant savings can be made through deploying thinner wafers that use less silicon, insists a new paper published by MIT and NREL. And as manufacturers are increasingly hitting dead ends on other routes to cost reduction, this option could be back on the table for many.
Ingeteam unveils new residential hybrid inverter
The manufacturer said its new hybrid device includes a maximum power point tracking system, which makes it ideal for east/west oriented rooftop PV systems. The inverter is available with power outputs of 3 kW and 6 kW and is compatible with most lead-acid and lithium-ion batteries that are made by leading storage specialists.
A new technique to get the right angular-tilt
UK scientists are proposing a new approach to calculating the optimum angular-tilt of PV panels for a planar surface at a particular site. In their view, the new technique may unlock innovative yield optimization methods for the installation of PV systems.
Raising the efficiency of polycrystalline cells with new luminescent EVA film
Chinese researchers have developed a pure EVA film, which they claim can enhance the conversion efficiency of conventional crystalline solar cells by around 0.50%. The film is able to convert UV light into strong visible light.
Zinc-air battery aims for extremely low $45/kWh cost
New York state has chosen Zinc8’s zinc-air battery to demonstrate the technology’s viability over a three-year period in a 100 kW/1 MWh storage system.
Japan’s fifth solar auction delivers final lowest price of $0.10/kWh
Only 39.8 MW of PV projects were allocated in the fifth round of Japan’s procurement program for large-scale solar. The lowest price offered was ¥10.99/kWh ($0.10) and the highest ¥13.0, for an average price of ¥12.57.
Spain reaches 8.7 GW of cumulative solar
The country saw the addition of 3.975 GW of new solar installations last year. Most of this capacity comes from solar projects selected by the Spanish government in the renewable energy auction held in July 2017.
ERA-Net awards 23 future energy pilot projects across Europe
Under the umbrella of the European Union’s Horizon 2020 initiative, the research platform ERA has initiated a new batch of future energy projects. Looking at the list of winning projects, it is easy to tell that hydrogen, virtual power plant, and blockchain projects are really at the center of what Europe thinks will be important for its net-zero carbon plans by 2050.
