The blockchain club

Open-source blockchain platform Energy Web Foundation has revealed the number of its affiliates has risen from 37 last month to 100. New members include EnBW, Total and the State Grid Corporation of China. The platform was conceived to create an energy-blockchain ecosystem and to accelerate the energy transition.

Global solar demand reached 104 GW in 2018

According to new figures released by SolarPower Europe, last year saw 1.4 GW more new solar generation capacity than trade body had expected. Lower demand in China was compensated for by stronger developments in emerging markets.

Floating solar reaches new territories

In Cambodia, Singapore’s Cleantech is building a 10 MW solar plant including a 2.7 MW floating section, and in Lithuania, state-owned utility Lietuvos Energija is deploying a floating plant at the Kruonis pumped storage hydroelectric power plant.

Kyocera uses blockchain to test virtual power plant based on solar and storage

The module maker and electronics giant is testing the feasibility of a complex virtual power plant with a blockchain platform provided by US-based LO3 Energy.

Australian scientists use hydrogen atoms to boost solar cell efficiency

Researchers want to better understand how hydrogen atoms may improve the performance of phosphorus-doped multicrystalline silicon (mc-Si) films for passivating contact solar cells.

Pacific island nation re-tenders big solar-plus-storage project

An initial tender on Palau was won by French energy company Engie, through its unit Engie Electro Power Systems. The 100 MW microgrid project consisted of coupling 35 MW of solar and 45 MWh of storage with diesel generation.

Super-grids vs prosumer states: storage may decide the battle

Indra Overland, head of the Center for Energy Research at the Norwegian Institute for International Affairs, explains how the world’s future energy landscape may include pan-regional super-grids. However, prosumer states seeking energy independence could also be in the mix. According to Overland, the two developments will go hand in hand and the balance between them will be determined by the competitiveness of storage technologies.

Japanese scientists seek to lower costs of PV-powered hydrogen

A research team has conducted a demonstration of economic feasibility for battery-assisted, low-cost hydrogen production from solar energy. The scientists claim their system will mean hydrogen can be produced for $0.15-0.25 per cubic meter.

Jinko achieves 24.2% efficiency for its n-type monocrystalline cell

The Chinese module maker said the result was certified by the Photovoltaic and Wind Power Systems Quality Test Center at the Chinese Academy of Sciences. The record, Jinko said, is thanks to its high quality n-type wafers, selective doping technology and advanced fine-line printing.

‘No alternative to 100% renewables’

Transition to a world run entirely on clean energy – together with the implementation of natural climate solutions – is the only way to halt climate change and keep the global temperature rise below 1.5°C, according to another significant study.
