Although PV trails wind and nuclear in terms of its anticipated future footprint, the opposition party’s attempt to outflank left of center rivals on climate change has resulted in one of the world’s most ambitious national roadmaps towards a zero-carbon future.

The Netherlands-administered Caribbean island last year saw almost half its power demand provided by a 4.1 MW solar-plus-storage plant, commissioned in late 2017. The facility generated 6.5 million kWh of the 14.3 million kWh of electricity consumed in the territory in 2018.

Renewable energy is rapidly being adopted by mining companies as the combination of off-grid power and cheaply available renewables offers a strong business case.

A German start-up achieved more than 99% efficiency when charging a vehicle developed by the Bochum University of Applied Sciences with electricity from solar cells. Ambibox’s DC charging technology was used in a research project in the Australian desert.

Analyst WoodMac has spelled out the urgent need to decarbonize the global hydrogen production industry. While the fuel can offer a sustainable grid balancing act for intermittent renewables, in its current fossil-fuel driven form it is pumping out more than 800 megatons of carbon into the atmosphere every year.

Renewables may be making encouraging advances in the south Asian nation but the natural gas infrastructure deal announced today by the Saudi power company at a stroke eclipses the 375 MW of solar capacity in Bangladesh and its 609 MW development pipeline.

In this op-ed for pv magazine, Roy Torbert and José Juan Terrasa-Soler, of the Rocky Mountain Institute and Resilient Power Puerto Rico, respectively, analyze the cost of Puerto Rico’s energy recovery and the role that microgrids play in reconstruction and resiliency.

Although the International Energy Agency’s latest renewables report forecasts impressive solar growth there is still a nagging feeling it has produced conservative estimates and the emphasis on sharing costs with grid operators is predictable.

The islands of the Caribbean have been focusing on the deployment of storage solutions, minigrids and microgrids in response to the damage their power systems suffered during the 2017 hurricane season. But with the opportunities, there are also challenges.

Two German companies will develop one of the largest off-grid PV and storage projects to date. The low cost of the technology and expense of conventional generators is likely to see the hybrid plant recover its costs in three to seven years.
