Integration methodologies for solar-assisted heat pumps

Italian scientists have assessed the technical potential of vapor compression heat pumps assisted by photovoltaic-thermal systems. They analyzed two main configurations of this combination describing the advantages and disadvantages of both solutions. The cheapest and easiest to deploy system is a single-source direct-expansion (DX) configuration for hot water for space heating or domestic hot water.

Europe’s gigafactory boom – 25 by ‘25

A gigafactory, as the name indicates, is a facility that aims to produce Li-ion cells at a gigawatt-hours scale of total capacity, so they can then be used in electric vehicles or stationary storage applications. The global production capacity of Li-ion cells is expected to reach 740 GWh by the end of 2021 – almost a threefold increase from 2017 – and Europe will account for 8% of the total. João Coelho, an analyst at Delta-EE, looks at how Europe plans to catch up.

Southeast Asia’s big PV plans – 27 GW by 2025

PV markets in Southeast Asia have picked up over the past two years, driven by the astounding growth of Vietnam. Regional policies, combined with growing demand for renewable power in the manufacturing industry, will result in 27 GW of new PV installations across the region over the next five years, writes IHS Markit analyst Dharmendra Kumar. PV installations in these countries are driven by attractive feed-in tariffs, net energy metering, tariff-based auction mechanisms, and other incentives.

Strong growth predicted for Middle Eastern solar PV

The Middle East, and the Gulf in particular, has been home to record low solar tariffs in recent years. Major projects are being awarded via tenders, with prices gradually closing in on a remarkable 1 USDct/kWh. Of course, this is no coincidence due to the region’s favorable solar conditions: availability of cheap and sunny desert land, low labor costs, cheap project financing, supportive tax regimes, large projects benefitting from economies of scale, well designed tender structures, and decreasing PV component prices.

Politicians tend to overpromise, except when it comes to solar

The speed of all transitions is inherently underestimated, and solar PV is no exception. The EU has grossly underestimated its coming of age, as its forecasts for 2020 were off by 67% for the Netherlands and 74% for Germany, writes Rolf Heynen, CEO of Dutch New Energy Research.
