How effective is solar-to-chemical energy conversion?

Significantly, the solar-to-chemical energy conversion (SCC) process achieved successful implementation under low concentration of photocatalyst usage (0.4 g·L −1) and in open air conditions (Supplementary Fig. 20, Supplementary Movies 1 and 2), with an impressive efficiency of 2.4% in pure water and 3.6% in lake water (Fig. 3a).

How efficient is solar-to-chemical conversion in ambient conditions?

Ye, Y.-X. et al. A solar-to-chemical conversion efficiency up to 0.26% achieved in ambient conditions. Proc. Natl Acad. Sci. USA 118, e2115666118 (2021).

How efficient is solar to hydrogen (STH)?

Numerical analysis shows that the solar to hydrogen (STH) efficiency reaches 19.85 % without waste heat recovery. Zhang et al. [24, 25] proposed an integrated system that integrates porous heat absorbers with tubular SOEC, and numerical studies show that the integrated reactor can achieve 25.58 % energy conversion efficiency.

What is solar-to-chemical conversion (SCC)?

Solar-to-chemical conversion (SCC) provides a promising avenue for resolving the energy and environmental crises that afflict contemporary society by harnessing the largest renewable energy sources on Earth 1, 2, 3, 4, 5, 6, 7, 8.

How efficient is a solar-to-hydrogen reactor?

Assuming a typical photovoltaic efficiency of 20 %, the proposed reactor has a maximum solar-to-hydrogen efficiency of 17.18 %, and this value can increase to 20.64 % when integrated with the waste heat recovery system.

How efficient is a solar-thermal collaborative SOEC system?

Theoretical analysis shows that the solar to hydrogen (STH) efficiency of the solar-thermal collaborative SOEC system can reach 33.3 % ideally . However, this value is sensitive to the combined form between solar heat and electric power, and the reported efficiency is much lower in real practice [10, 11].
