A new report from the European Heat Pump Association (EHPA) has shown that heat pump technologies are currently unable to compete for heating with gas due to high taxes and levies on electricity. According to its experts, a carbon tax, or removing this tax imbalance, may create a level playing field for renewable technologies in the heating sector.

U.S. start-up EnerVenue has secured funding to build a gigafactory to produce nickel-hydrogen batteries for large scale renewable and storage applications. The battery has an efficiency ranging from 80 to 90%, depending on the cycle rate, and its energy density per square foot is equal to, or better than lithium-ion batteries, according to the company.

Green hydrogen cost may reach between €0.7 and €1.8/kg by 2030 and €0.3 and €0.9/kg by 2050, according to a European research team led by the European Technology and Innovation Platform for Photovoltaics. The scientists found that the levelized cost of hydrogen (LCOH) could drop from around €0.031-0.081/kWh currently to €0.02-0.05 by 2030 and €0.01-0.027 by 2050.

CE Oltenia wants to build eight solar parks at three of its coal power plants and five of its coal mining sites by 2026. This new capacity should replace installed power from coal that the company wants to shut down over the next five years.

The Massachusetts Clean Energy Center (MassCEC) showed, through a pilot incentive program, that whole-home heat pumps are a feasible solution for heating when switching from gas. Project costs, however, were found to be higher than expected.

Through the procurement exercise, the government wants to build ground-mounted solar power projects on an independent power producer (IPP), and build-own-operate (BOO) basis.

The modular power station comes with two lithium iron phosphate (LFP) batteries and has a capacity of 6 kW/24.6 kWh. It relies on a 3 kW pure sine wave inverter which the manufacturer said is able to adjust the AC charging rate.

The module is claimed to be one of the top five most performant heterojunction solar modules, in terms of power density, with the champion panel achieving 214.15 W/m² and the average device 209.5 W/m². The panel showed an efficiency ranging from 20.95% to 21.41%.

Antonio Delgado Rigal, chief executive of energy forecasting service AleaSoft, tells pv magazine that skyrocketing gas and electricity prices are putting the global economy under strong pressure, while also opening up huge opportunities for solar, renewables and green hydrogen. He says current gas and electricity prices, along with rising CO2 prices, already make green hydrogen competitive. He therefore calls for immediate action on building new capacity, but acknowledges that a quick end is not yet in sight for rising prices.

At the end of June, Italy’s cumulative PV capacity surpassed 22.4 GW. Rooftop PV keeps driving the Italian solar market.
