Dedicated to Continuous Innovation
Dubai Electricity and Water Authority (DEWA) organised field visits for 217 participants in COP28 to the Mohammed bin Rashid Al Maktoum Solar Park. Most of the visitors were from outside the UAE. The visits, which were organised during COP28, included the Innovation Centre and the 4th phase of the solar park. The guests praised the …
Abstract: This investigation reports the thermodynamic efficiency analysis of a hybrid ZnSO4/ZnO water-splitting cycle. The data required for efficiency calculations are gathered from HSC Chemistry Software. The prime goal is to examine the effects of the thermal energy needed for heating inert sweep gas and separating the gaseous components in the cycle on the solar-to-fuel …
Abstract: Ceria-based H2O/CO2-splitting solar-driven thermochemical cycle produces hydrogen or syngas. Thermal optimization of solar thermochemical reactor (STCR) improves the solar-to-fuel conversion efficiency. This research presents two conceptual designs and thermal modelling of RPC-ceria-based STCR cavities to attain the optimal operating conditions for CeO2 reduction step. Presented hybrid geometries consisting of cylindrical–hemispherical and conical frustum–hemispherical structures. …
As of November 30th, the POWERCHINA Gonghe 50 MW Molten Salt Tower CSP Plant, constructed with the participation of Cosin Solar, achieved a new monthly power generation record of 12.222GWh in November since its commissioning. The operational records indicate that the plant’s theoretical power generation for the month was 12.2352GWh, while the actual power generation …

When thinking about renewable energy, most people conjure visions of solar panels on rooftops or elegant white wind turbines, few imagine the humble greenhouse. And yet, a greenhouse with a twist is key to a groundbreaking solution in bringing net-zero to the tough-to-disrupt industrial heat sector. Industrial heat is the world’s largest end-use of energy …
There’s a rush on to capture the sun with mirrors. Fields, deserts, and areas the size of capital cities, are being covered in big shiny heliostats, and sunlight focussed on troughs, tubes and towers, designed to bring us out of the fossil-fuel age and into a greener, more sustainable future. Wes Stein CSIRO solar research …

In the first quarter of 2024, India plans to put out a tender for renewable energy that includes not just a carve-out, but the largest ever, requiring over 50% to be supplied by Concentrated Solar Power (CSP), the thermal form of solar electricity. There is renewed policy interest in CSP as a longer-duration source of …
