High-efficiency “spacecraft” solar cells are coming down in price
Solar cells commonly used in spacecraft are highly efficient but too expensive to be used commercially down here on Earth. Two methods, HVPE (hydride vapour phase epitaxy) and the preferred MOVPE (metalorganic chemical vapour phase epitaxy), have been used to make these super-cells, reaching efficiencies of 29.1%. The National Renewable Energy Laboratory (NREL) says its […]
ATEX proof WiFi equipment for remote work
RX Antenna Coupler Enhancement Solexy’s patented (7,057,577) Explosion-Proof Antenna Coupler permits the installation of Off-the-Shelf non-Ex certified antennas in hazardous areas. This coupler is designed to be used directly with listed explosion proof housings or conduit fittings. An integrated blocking circuit prevents hazardous energy reaching the antenna if a radio, modem or access point failure […]

Offshore Klaipeda 2020. 700 MW wind farm in the Baltic Sea.
Virtual workshop “Offshore Klaipeda”: over 150 participants from Lithuania and abroad The Offshore Klaipeda online event brought together international audience to discuss about the new opportunities emerging together with the ambition to develop 700 MW wind farm in the Baltic Sea, nearly 30 kilometres from the Lithuanian shore. Virtual workshop was attended by participants from Lithuanian […]
Lithium-Sulphur batteries: cheaper, greener, hold more energy
The rapid expansion of electric power across the world is putting a strain on battery production. The standard lithium-ion battery depends on minerals and metals in limited supply, so alternatives are needed urgently. Mahdokht Shaibani at Monash University describes the work of her team on developing lithium-sulphur batteries. There are many advantages, not least the […]
Biogas and Biomethane’s untapped potential across the world
The IEA’s World Energy Outlooks have no doubt that electrification alone cannot meet our climate goals. That’s why natural gas continues to play a major role. But biogas and biomethane have the potential to replace 20% of that gas, says the IEA’s special report “Outlook for biogas and biomethane: Prospects for organic growth”. At present […]
Investing for tomorrow, because Energy subsidies will decline 25% by 2050 – analysis
IRENA has modelled energy subsidies to 2030 and 2050 for their pathway to meet the Paris targets. Here, Michael Taylor summarises their findings. Firstly, they estimate today’s global direct energy sector subsidies to be $634bn/year (2017 figures). The vast majority, $447bn, went to fossil fuels. (By the way, he points out that none of these […]
Clean Energy threatened by lockdown of critical minerals supply
Clean energy technologies depend on the reliable and growing supply of critical minerals and metals, far more so than the old fossil fuel world. An EV uses five times the quantity needed by a conventional car, and an onshore wind plant requires eight times that of a gas-fired plant of the same capacity. Hence, electric […]
